Racers eat all sorts of things hoping to extend endurance. A long history of drugs and supplements have been used from illegal to unhealthy to useless to good common sense nutrition.
Some racers load on unhealthful simple sugars hoping that will maximize needed carbohydrate stores called glycogen in the muscles. Others shun carbohydrates, even healthy needed nutrition in fruit and vegetables because they want to lose weight. A main effect of low carbohydrate diets is loss of muscle glycogen, quickly reducing size and water weight, giving the illusion of weight loss, and reducing exercise ability.
Another factor was identified in a study at Oxford University looking at using a high-fat diet. They found "stark reduction in physical endurance and a decline in cognitive ability after just nine days." Researcher found increased levels of a protein called the 'uncoupling protein' in the muscle and heart cells of rats on the high-fat diet. This protein 'uncouples' the process of burning food stuffs for energy in the cells, reducing the efficiency of the heart and muscles.
The study used rats, which have different nutritional needs than people. Previous rat nutrition studies led to higher than needed protein estimations, still believed by body builders hoping to build muscle through eating. This rat study seems to be in line with longitudinal dietary studies of human athletes who could not run as long on a treadmill or navigate as well through a maze. Dr Andrew Murray led the work at Oxford University. He stated, "We found that rats, when switched to a high-fat diet from their standard low-fat feed, showed a surprisingly quick reduction in their physical performance."
Primary Source: 'Deterioration of physical performance and cognitive function in rats with short-term high-fat feeding' by Andrew J Murray and colleagues. The FASEB Journal, 2009; DOI: 10.1096/fj.09-139691. Copy of the paper: http://www.fasebj.org/cgi/rapidpdf/fj.09-139691v1.pdf
What they called a high fat diet was 55 per cent of the calories from fat. This may be less total fat than what I observe many people eating with fast food and junk food. Patients come to me proudly showing a food diary that they think is balanced because it lowers the total fat percentage of a recipe with lard by adding sugar. That is still the same high fat amount. Reduce your total fat, and keep your head not to avoid vegetables because they have a high percentage of carbohydrate. The percentage is high, not the total. If you have a one-dollar bill in your pocket and that's all, your pocket has 100% dollar bills, but not a lot of them.
In American Samoa, 93.5% of the people are estimated to be overweight since changing traditional complex carbohydrate low fat meals to Western imports of fatty food, junk sugar, and processed meat like Spam. In the Republic of Kiribati, another tropical island nation of the central Pacific, 81.5% are estimated overweight for the same reasons. Egypt began an increase of obesity when they began importing fast food. In the United States, over 65% of the people are considered overweight, related to considerable fat and high simple sugar from processed food with corn oil and high fructose corn syrup.
If your body chemistry, your temperament, medications you take, or economic situation pushes you to gain body fat from eating too much unhealthful food, eating less of it is still key to reducing overweight. I am not a nutrient biochemistry specialist, just a physiologist. For health and sports success over the long term, a working generality is to stop eating the fat and refined sugar of junk food, fast, food, and processed food, and many so-called "health-foods" which are expensive candy or over-processed products. Try an apple or favorite fruit and some walnuts for healthy exercise and endurance.
There are many components of health covered in the hundreds of Fitness Fixer articles already here, including how to fix injuries, stop pain, and improve sports and life abilities without expensive unhealthful sports food or drugs and medicines that reduce overall health.

Exercise and Weight Loss Reduces Kidney Disease and Death
Wednesday, October 14, 2009
Jolie Bookspan, M.Ed, PhD, FAWM
We recently found a cure for "irony deficiency disease." My near-7 foot tall husband and I were walking to a Vidocq forensic society meeting. A bake sale was set up in the building lobby - junk food, refined junk pastries, pies with artificial colorings. The sign stated "Bake Sale for Kidney Disease." I asked which items caused the most kidney disease. I was sure it was a staged joke for a commercial on nutrition awareness. The sellers were disappointed with me. Apparently, it was a real bake sale. "Bake Sale for Kidney Disease" is true, both for them and their kidneys.
Research reported in the Clinical Journal of the American Society Nephrology of pooled data from 13 studies showed found, in obese adults with kidney disease, losing weight through diet and exercise prevented additional decline in kidney function and reduced proteinuria, which is excess excretion of protein in the urine, a major characteristic of kidney damage.
Regular exercise of the recommended amount cuts risk of death in patients with chronic kidney disease by 56%, according to an analysis of National Health and Nutrition Examination Survey (NHANES) data. People who exercised, but less than recommended levels were still 42% less likely to die during follow-up than sedentary people.
1. Weight Loss Interventions in Chronic Kidney Disease: A Systematic Review and Meta-analysis. Sankar D et al. Clin. J. Am. Soc. Nephrol., September 17, 2009 as doi: 2. Physical Activity and Mortality in Chronic Kidney Disease (NHANES III). Beddhu S, et al. Clin J Am Soc Nephrol 2009; DOI: 10.2215/CJN.01970309. doi:10.2215/CJN.02250409.
Obesity is a major factor in kidney disease. A large percentage of the United States adults and children are overweight or obese, increasing their risk of kidney ailments, plus diabetes and high blood pressure, which in turn affect kidney function. More than 20 million Americans already have chronic kidney disease, with the number and severity growing.
Researchers of the Systematic Review and Meta-analysis stated,
"The health care costs that are associated with this increase are staggering. In obese adults, weight loss may offer real benefits in terms of the kidneys, in addition to the heart-related benefits of shedding excess pounds."

In the hot days of summer, common warnings involve avoiding the heat. What about the advantages of heat? Hot environments can improve your health in several ways.
Done right:
Exercising in the heat improves your fitness level and ability to exercise.
Exercising in the heat increases your tolerance to heat, making life more comfortable in the heat.
Exercising in the heat prevents the decreases in heat tolerance that otherwise occur with increased age, which can be unhealthy, even dangerous.
Exercising in the heat makes positive changes in your body that improve your fitness. You increase blood volume, improve cooling ability, make changes in sweating, increase the vasculature that helps circulation, cooling and exercising at the same time, increase specific chemical compounds in the body that improve health and ability to exercise.
When you exercise and increase body temperature, your body produces more of an interesting compound called heat shock protein. Heat shock proteins are families of proteins that do several things including preventing other proteins from damage by infection, ultraviolet light, starvation, heat, cold, and other harsh conditions. Heat shock proteins are thought to mobilize immune function against infections and diseases, even cancer.
Improved ability to tolerate heat without discomfort, called heat adaptation, occurs fairly quickly - with large improvements within the first week of exerting in the heat. Exercising in heat is more effective to produce heat acclimatization than heat exposure without exercise. Aerobic fitness is a major factor in heat tolerance.
It is a myth that you must avoid sweating to stay healthy. Exercising enough to sweat makes you more flexible, increases many chemical reactions in your body that are healthy. Sweat itself has compounds beneficial for your skin and body. Don't worry that you must exercise only indoors in air-conditioning in order to do healthful exercise. A protective environment does prevent initial discomfort, but reduces benefits and the ability to be comfortable in the heat.
This all does not mean to go out and cause yourself heat injury by overdoing without thinking. It is to gain the many benefits of exercising safely in the heat
I will cover more physical changes from exercise in the heat that improve health and exercise level in future articles.

Reader Robert Davis has been enthusiastically sending in success story after success story. He sent his first story of fixing a painful back injury from weightlifting - Fixed Injuries, Got Strong, With Functional Exercise.
Since getting the idea of using healthy daily movement instead of injurious movement during daily life and exercise, Robert stopped major causes of his injuries. He has rapidly been getting strong using fun functional exercise, and improving function. He has been taking ingenious photos using his camera phone. His stories and photos will be posted. He is sending them in fast and furiously. I enjoy hearing how he experiments with each thing, and sees and understands how they work so he can incorporate the concepts into daily movement, not just going thorough arbitrary motions and calling it exercise.
We are still having problems uploading photos and movies for you - since October. It has been a time-intensive and difficult process to get any photos at all uploaded for these posts. It has changed and delayed a few of the articles I wanted to write for you. When Healthline staff can help, they will. Robert generously made a page to store visuals so you can link and see them. Start with:
Watch how he uses a healthful squat for real life, not just 10 times in a gym.
Robert writes:
"Make a mess and pick up only one item at a time via a squat. If you need to clean the house only pick up one item at a time. The constant up/down motion of the squat etc should get the heart rate up for a good cardio workout. Why not kill two birds with one stone? Tired of the stationary bike? Do this for a half hour:)"
Good bending is natural built-in cardiovascular exercise, leg strength and stretch, Achilles tendon stretch, hip strengthener, warm-up for stretching, and back pain prevention, since it stop one major cause of back pain - bad bending (bent over at the waist or hip). Done properly, good bending strengthens knees and does not cause knee pain. The Related Posts below explain more.

The Shinobi no Mono, or the Ninja of old Japan, were renowned for their running speed and endurance.
Running drills called "ashi" (foot or feet) were an important part of Ninjutsu physical training. Try this basic Ninja ashi, or running drill:
Put a straw hat on your chest.
Run without holding the hat with your hands or other fastening.
Run so fast that the hat does not fall - this requires keeping a minimum speed for the duration of the ashi drill.
Where is the photo? He (or she - there were female Ninjas) must have run by so fast you didn't see. We are still working on the problem of photos not uploading. Healthline staffer Jerry has been helping to upload several photos for posts to come. Thankyou Jerry.

Here is Friday Fast Fitness - How to know what heart rate will give you a cardiovascular training effect.
Several formulas calculate exact heart ranges and "target heart rates." There are a variety of commercial (expensive) heart rate monitors. Arguments in sports medicine continue on which is the right formula and if heart rates in water or at elevation can be calculated the same way. These issues will be covered in posts to come. For now:
Your body is smart. Heart rate generally follows "perceived exertion." If you feel your running or other exercise pace is moderate, your heart rate is likely to be at a moderate training range. If it feels light, then heart rate will likely be too low to give much training effect.
Find something you enjoy enough to continue more than ten minutes at a time.
Keep a pace that you feel is moderate to hard, depending how you like it.
If your running or other exercise pace feels moderate, it is also moderate for your cardiovascular system. If it feels hard, your heart and body and mostly likely working hard for your current level If it feels light, then it is too light to give much training effect.

The new Indiana Jones movie came out this past weekend, the Kingdom of the Crystal Skull. It is set in 1957 with fun fitness and iconry of the era, for future blog posts. Today - the Rocket Sled.
In the early part of the movie, Indiana Jones and the Soviet Russians brawl through a US military testing base in Nevada. Jones and a Russian officer wind up on a rocket sled, which blasts them on a speed track into the desert.
Rocket sleds are one of several devices that create and test the effects of high acceleration on equipment and the people who use them. High acceleration forces occur when jets take off quickly, when launching a space flight, to eject from a hit (compromised) fighter jet, on roller coasters and spin and fall rides, when you fall from a height, and any time you change speed and/or direction quickly. Interesting changes occur in the body under acceleration. Acceleration is one of the areas of my study as a research physiologist and was my work for a time at two facilities testing air vehicle and human systems.
G-force is a measure of acceleration, not force, but the term g-force is also used for the reaction force that results from acceleration. More on meaning, spelling, and math of g and G in another post. Too much g-force can result in g-LOC (Loss of Consciousness), pronounced "jee-lock"in English, but just as meaningful when using the Cyrillic pronunciation of "loss." When piloting a multi-billion dollar property (the fighter jet) G-LOC is not a good thing for anyone. The pilot may convulse, called "doing an Elvis" because the flailing looks like playing an air guitar - a real air guitar. Then the pilot may "ding" (lose consciousness) and the vehicle may "descend below the level of the terrain" (crash) and "disperse energetically" (explode) and "value unfavorably" (be destroyed), and the crew and anyone they land on may "achieve a negative health status" (die).
So we test.
A rocket sled is a small platform. Rockets propel it on the ground on rails. It creates high onset g-forces for a time limited to the length of the track. When personnel or equipment riding it sit as in a car or plane, they experience acceleration pressing them from front to back (on an x-axis).
To measure the higher g-forces with short onset experienced in jet bail-out procedures, a vertical ejection tower can be used. A small seat is propelled quickly upward by a contained blast force under it (like lighting a bomb). If they are positioned to sit upright, the acceleration acts on them from head to foot, on their y-axis.
To experiment with varying accelerations over different amounts of time and onsets, one device used is a centrifuge. A long support arm swings around and around a center anchoring point -like swinging a ball on a string around your head. A container, often ball shaped, at the end of the support arm holds the equipment or personnel being tested. The ball can rotate to position the people inside at any angle to simulate the changing positioning of a cockpit during maneuvers, for example.
What happens to the people in these testing devices? Often they throw up all over my nice equipment. Some of my test subject pilots used to have contests who could eat the worst thing to redisplay on testing day. One ate plastic bugs just for the fun he was sure to cause - then he didn't throw up, no matter what we did to him. In vertical (y-axis) ejections, there is high impact and acceleration forces on the discs and spine. Back injury is a concern for ejection scenarios. Vibration, both during acceleration and non-acceleration situations, such as for helicopter and jack hammer operators seems to be a high contributor to back pain. It is not known if the various vibration devices sold as fitness devices are of the kind (vibration frequency or amplitude) that contribute to joint pain. G-LOC is another consideration. Why do we test it? To see how to prevent it, if we can screen for who is more likely to get it, if we can train those prone to it to be more resistant, and so on, in g-force tolerance improvement programs (g-TIP).
The set of photos at right is a well-known one of USAF Colonel John Paul Stapp, M.D., Ph.D., riding the rocket sled. He was a pioneer of acceleration study and is also known as the originator of the expression "Murphy's Law" for things that can go wrong. The effect on his face along the x-axis is not from his high speed, but the acceleration which is increasing in photos ii and iii, and decreasing in v and vi. Even though his speed is greatest in photo iv, speed is not increasing or decreasing much, so there is little effect.
More on the interesting effects of acceleration and environmental testing from roller coasters to jets to movies in posts to come.

Fast Fitness - Easy Handstand for Balance, Upper Body Strength -The Movie
Friday, May 09, 2008
Jolie Bookspan, M.Ed, PhD, FAWM
Here is Friday Fast Fitness - a quick, safer way to try a handstand. Standing on hands has many health and strength benefits and can be easily practiced in this way.
My student Dennis, Olympic medalist in wrestling, demonstrates in this short movie. Click the arrow to watch the movie:
Stand with your back about a foot in front of a wall, and crouch to put your hands on the floor (avoid slippery surface)
Put one foot high up on the wall, then lift the other foot up too
To get down, step one foot back down, then the other
Keep breathing. Smile. Relax. Send in your own photos of trying this. Be safe and have fun.
Here is Fast Friday Fitness - if you have been afraid to try a handstand, here is a quick easy way to have success. You will strengthen your hands, wrist, arms, shoulders, upper body, and core, practice balance, and get blood circulating.
Crouch down near a wall (avoid slippery floor)
Put one foot high up on the wall
Lift up the other foot
To add a nice stretch on the hamstrings, lift one leg away from the wall into a wide split position in the air, as below.
If you have uncontrolled glaucoma or high blood pressure, ask your care providers first.

We are here working in Asia. Everywhere, we see schoolyards with kids playing sepak takraw. Modern sepak takraw is played on a court with three players on each side. Players don't use their hands to volley. They use feet, legs, shoulders, and head to keep the ball in the air, volleying back and forth. Main features of sepak takraw are acrobatic mid-air kicks to keep the ball in play, and the athleticism and speed of the players.
Sepak takraw has been played in Southeast Asia for hundreds of years. The word "sepak" is Malay for kick and "takraw" is the woven ball. In Thailand, the game is often simply called Takraw. In 1984, a Thai inventor revolutionized the sport with a synthetic takraw to replace the slower traditional rattan ball.
Takraw has roots in Malaysian, Chinese, and other national games. In Bangkok Thailand, there are wall paintings at the Wat Phra Kaew (Temple of the Emerald Buddha) of Hanuman, the Vanara (Monkey-like) Hindu god, playing takraw in a ring with his monkey troops. The game developed into teams competing across a court with a net, about the size of a badminton court. This modern-day version is a Southeast Asian specialty.
Thailand wins most of the gold medals at the Asian Games. Here is a motion clip of just 48 seconds of playing Takraw. Click the arrow to watch.
In Monday's post on Swimming and Pulmonary Edema Part I, Katharine, an Ironman Triathlete, told of having pulmonary edema of swimming twice this year and asked if warm up or fluids were involved. US Open Water Swimming also interviewed me about pulmonary edema. Here are some things they asked.
1. What is pulmonary edema and why should swimmers know or be concerned about it?
Edema means too much fluid accumulation. Fluid suddenly fills the lungs. The left side of the heart is not pumping properly. It can cause you to have to stop a race. It can sometimes cause serious illness and death.
2. Is it more likely to occur in cold water?
It seems to be more likely in cold water. It has occurred in surface swimmers and scuba divers in both cold and warm water. Cold is only one of the several proposed causes.
Causes or contributors seem to be things that increase cardiac preload and afterload, including immersion in water, cold water, heavy exercise, negative pressure breathing (like breathing with a snorkel, and swimming with the chest below the surface and even the slight elevation of the head to breathe in), and drinking too much water or other fluids before swimming. Don't drink lots of water before swimming.
3. What are the signs and symptoms?
Unusually shortness of breath (not just fatigue) and coughing bloody froth. No chest pain.
With a stethoscope you can hear rales, an abnormal rattling breathing sound. Chest x-rays show the classic pattern of pulmonary edema. When blood oxygen in the arteries is checked, arterial O2 may be lowered.
4. Do wet suits provide any measure of protection against PE?
Difficult to say since it has occurred in people with and without wet suits. I haven't seen charts where the numbers of each predisposing possibility, like protective garments and temperature, were compared.
5. Can medical personnel easily detect PE?
Pulmonary edema is not subtle. The person is usually gasping and spitting pink froth, and asking for help with a worried look.
A swimmer who develops shortness of breath and cough in a race may have something else like exercise induced asthma.
6. What is the first aid if PE is suspected?
Get them out of the water. Sit them up to elevate the head, if conscious. Give them 100% oxygen by mask, and get them to the emergency facility.
7. If PE is untreated and the athlete continues to the race/swim, what could happen?
Depends how serious. Symptoms can resolve on their own or they can get worse. I wish I knew the future for them, but it's like other injuries. There have been deaths. We wonder how many people who suddenly went under were not drowning but developed pulmonary edema. We have no way yet to tell. Drowning also produces pulmonary edema (after the fact). Repeat cases of pulmonary edema can occur in the same person.
Interestingly, the frothing pulmonary edema occurs in racehorses after hard races. They are blowing bloody nose froth all over, but veterinarians have reassured me that the horses are fine. Any readers who are veterinarians, please tell me more. If a person is frothing, get help.

"I am an Ironman Triathlete and have recently experienced symptoms of swimming induced pulmonary edema on two occasions this year and am trying to find as much information about this condition as possible. I have a background in swimming and have not experience this phenomena until recently. In both instances, my breathing became labored and fluid built up in my lungs during the early stages of a competitive triathlon swim.
"The most recent instance of what I suspect was 'SIPE' (Swimming Induced Pulmonary Edema) was on July 22nd at Ironman USA in Lake Placid. After the swim portion of the event, I had to be taken to the hospital as I was unable to breathe and was coughing up a 'pink frothy foam.' I felt normal within 24 hours and have still been able to continue to train as normal –initial ECG and Echo tests of my heart are normal, as well as a lung scan and x-rays of my lungs, throat and sinuses.
"The problem has only occurred in 2 out of 4 triathlon’s I have been in this year – and both instances occurred at approx. the 750m mark of an open water swim.
"It doesn't seem to be a common ailment so I’m trying to gather as much information on SIPE as possible from anyone who has studied it. I'm primarily trying to find out how to prevent it from happening. I am fine in training in the same 'open' cold water as I race it, so why is it happening on race day... Perhaps not enough of a swim 'warm-up' and an immediate elevation in HR... that along with added fluids in the days leading up to a long distance event such as an Ironman."
Warming up does not seem to be related to developing pulmonary edema. Why pulmonary edema can happen with swimming, what fluids have to do with it, and what to do, follow on Wednesday - click Swimming and Pulmonary Edema Part II .
Grunting in the gym made recent news. A member was forcibly removed from a gym when others complained. The article told of factions arguing who was right if grunting and other loud vocalizations when exerting for exercise were helpful or needless annoyance.
Exercise is supposed to be healthy and build discipline of mind and body. Antagonism and disputes are not healthy for mind or body. Moreover, both sides have missed the point.
Breathing out, either quickly or slowly in coordination with effort can help. It can be done silently - by exhaling without vocalizing. You can have both, the exhale and the peace. This quiet but forceful exhalation practice is used in many high exertion fields from martial arts to warfare to meditation.
Fighting ninjas were legendary for both focused effort and silent tactics. No sense making a war cry until it was needed for its better purpose - to increase tendency to submission by the other party on the receiving end of the cry. In other words, to be scary.
For exercise, focused exhalation can increase acceleration at specific points of the move to increase power. For heavy moves, it can help lessen increases of pressure in the chest cavity and blood vessels, depending how it is done. Sometimes, people put so much pressure into the exhalation that they increase internal pressure instead of prevent problems. Done either quickly or slowly, it can be used to strengthen the move by including expiratory muscles. Often in martial arts and yoga classes, we (teachers) use noisy breathing just to remind students to breathe at all. It is a cue until they remember to breathe on their own (quietly) instead of holding their breath.
In the war dances and drumming in many countries, in martial arts, and in meditation arts, a concentrated exhalation coordinated with effort is variously called kiah, kiai, hihap, battle cry, and other terms. Each school is certain that their own different translation and beliefs about these terms is the "right one." The exhalation can be vocalized in a short yell, a loud breath, or silent. In group efforts, from martial arts to hauling sheets on tall ships, to chain gangs, to exercise classes, it helps unify mood or keep cadence. Done without coordinating effort, it is called yelling, and sometimes it is just vocalizing in corny ways.
More about breathing, the kiai exhalation, and exercise for any sport are in the book Healthy Martial Arts.

Here is Friday Fast Fitness - Train speed and eye-hand coordination while having fun.
Have you seen martial arts movies where the master catches a fly with his chopsticks? The true master doesn't restrain or harm the lives of others. In the spirit of healthful exercise, World Vegetarian month and higher spirit, try this instead:
Tear a sheet of paper to different size pieces
Throw in the air
Catch as many pieces as you can as they flutter downward.
Want more? Use only one hand to catch. Then switch.
You can play this with children too. Get more exercise and prevent pain by using healthy bending to pick pieces up and start again.
"Vegetarians have the best diet. They have the lowest rates of coronary disease of any group in the country. [T]hey have a fraction of our heart attack rate and they have only 40 percent of our cancer rate." —William Castelli, M.D., Director, Framingham Heart Study, the longest-running epidemiological study in medical history
From my work in sports medicine, I will add to Dr. Castelli's work that I see fairly consistent reduction in joint pain and other pain syndromes when patients stop known "inflammatory foods" including meat and dairy.
October 1 is World Vegetarian Day (www.WorldVegetarianDay.org). The month of October is Vegetarian Awareness Month. The purpose is for a happier, more aware and respectful, and healthier society.

"You could exchange your "regular" car for a hybrid Toyota Prius and, by doing so, prevent about 1 ton of carbon dioxide from entering the atmosphere each year, but according to the University of Chicago, being vegan is more effective in the fight against global warming; a vegan prevents approximately 1.5 fewer tons of carbon dioxide from entering the atmosphere each year than a meat-eater does. The math is simple: You could spend more than $20,000 on a Prius and still emit 50 percent more carbon dioxide than you would if you just gave up eating meat and other animal products."
Feel encouraged. Being vegetarian or making occasional vegetarian meals does not have to involve any strange or expensive foods from specialty stores. You do not need any special pots or food processing equipment. It is a myth that vitamin supplements are necessary. Grocery bills can also be also far less expensive when you don't purchase meat (and don't substitute other expensive food that you do not need).

I will post easy-to-make healthful (real) food for athletes and exercisers, during October vegetarian month, and for Vegan month in November.

Parcours is pronounced par-core. It is a French word meaning "course" or trail. A parcours is a path with obstacles at varied intervals. You navigate using your body and brain, similar to steeplechase.
Some parcours are formally designed municipal parks. Some are impromptu collections of trees, walls, buildings, windows, and rocks. On a rainy day you can make your own in your house.
In ancient times, a course might involve days of travel. Today, several cities around the world have public courses used by people of all abilities and ages. Modern fitness programs use it, with names like freerunning and various brand names, but the idea is not new.
Stations may be a log to walk across, rings to swing on, various height and shape objects to stretch on and around, a place to see how far or high you can jump, something to balance on, a ladder or wall to climb over or under.
To get to the next station, you can walk, run, bike, skate, or whatever you can do. Parcours length varies from a block to miles. Some people make a day of it with picnics and rests between stations. Others go make a quick lunch run over part or all of the course.
In the early 1980s I was the first person to put exercise programs aboard cruise ships. Until then, cruises were associated only with deck chairs and food. I was told exercise would not catch on. I ran exercise, health education, and stretch classes, and led the scuba and snorkel trips. I also led a parcours, taking about an hour, all over the ship, from deck to deck, stem to stern, over and under tables, chairs, hatches, and railings, and through the cha-cha lessons. We ran, we walked, we balanced, we cha-cha'd, we tip-toed very fast to get away, we laughed.
Parcours uses the body in natural ways to build strength, spirit, and balance.
It can be healthier, better training, and more fun than doing artificial repetitions of an isolated exercise.
More to come on keeping parcours safe for joints, and preventing injuries.

The week before I left to teach at the Wilderness conference, I taught my University yoga class entirely on an exercise ball. I will post about functional movement on a ball in weeks to come.
We don't use three of the most ineffective things you can do on a ball - crunches, sitting on the ball (for almost anything), and arching the lower back over the ball. These seem to be three of the more common things done on the ball in fitness classes, but they are not fit or effective.
Another myth is that an exercise ball will magically make you sit straight. You can sit with as faulty positioning as on any other surface.
Most of my students brought in an owned or borrowed exercise ball. I brought in three more for students without access. Some of the students pin-balled cheerfully through the narrow doorway with a large inflated exercise ball. One came in on the subway holding hers. I managed a comic, calorie-burning commute with three on a bicycle. A few students brought theirs uninflated. Wow, such an idea.
They asked me if I had a pump.
I told them, "Yes, your lungs, blow it up."
They sat politely waiting for the other students who brought a pump to finish with theirs.
I chided them that people talk all about yoga and breathing but here was opportunity in the tangible. They sat politely waiting for the pump. I demonstrated - "fffooooooooou."
I told them that when I was small, I was transfixed when my father, a Russian ice swimmer, blew up a beach ball in one breath. I decided then and there that I wanted to do that. I experimented with bags. I'd inflate to all my capacity and compare the bag to my little chest. I later practiced this in my swimming career until I was measured by scientists who came one day to test our whole team. My lung volume (not counting residual that you cannot breathe out) came in close to 6 liters. They called me a sports car. I didn't know what that was and hoped they were not flunking me. Who knows how much was from my 35 to 40 mile a week swimming training, or inherited, or just lung size relative to height. Still, a "big engine" can be trained and added to the mix. Click the label "breathing" under this post for entries about training breathing and exercise capacity.
My students took a chance on believing me that breathing and yoga and health had something to do with real life, and took a big breath to the ball. Bigger, bigger, full. Then quick hands to cap it off. They laughed. Laughing is good for breathing too. Then we started class.
Take a nice full breath in right now. Let your lower abdomen come outward. Exhale normally.
Breathe when you cook, clean, and do daily life. Don't hold your breath or gasp.
Blow up balloons, pool floats, air cushions, enormous inflatable beach toys. Don't overbreathe and get dizzy.
Exercise until you have to breathe a lot. Don't let yourself get so out of shape that it ever becomes unhealthy to try fun exercise.

The study used rats, which have different nutritional needs than people. Previous rat nutrition studies led to higher than needed protein estimations, still believed by body builders hoping to build muscle through eating. This rat study seems to be in line with longitudinal dietary studies of human athletes who could not run as long on a treadmill or navigate as well through a maze. Dr Andrew Murray led the work at Oxford University. He stated, "We found that rats, when switched to a high-fat diet from their standard low-fat feed, showed a surprisingly quick reduction in their physical performance."
