“..The changes that occur to the cardiovascular system during exercise all have a common function: they allow the body to meet the increasing needs demanded from an increased workload on the body. Many components of the cardiovascular system work in tandem with one another to achieve this goal. Like a fine tuned machine, the components of the cardiovascular system are orchestrated by local mechanisms, as well as by the neural and endocrine systems, to supply the increase in demand. The role of the nervous and endocrine systems will be discussed in a later topic. To better understand the contribution of every mechanism, we will need to take a quick look at each in greater detail. The following physiologic factors perform a unique contribution to the overall goal of homeostasis. These will include:..”

Sweat Is Cool humankinetics.com
“..Sweating does for humans what panting does for dogs, but sweating does it better. Sweating is an effective way to stay safely cool in hot environments. That simple fact explains why humans are better than most animals at being physically active in the heat for prolonged periods. Animals that do not sweat cannot pant fast enough to keep up with the heat production of exercise. In humans, when body temperature increases slightly above normal resting temperature (98.6 ℉, or 37 ℃), the hypothalamus in the brain senses the increase in temperature and signals the sympathetic nervous system to dilate blood vessels in the skin and activate sweat glands. (See figure 10.3.)..”
Why do we sweat.mp4
The Science of Sweat By Tim Newcomb Dec 7, 2016 popularmechanics.com
From nerves to exercise, this is sweat’s cool factor.
“..When your body starts to heat up, whether it’s because of exercise, work, or outside temperature, your brain reacts by releasing sweat from the more than 2.5 million eccrine glands spread out across nearly all of your body, pouring liquid through pores to lower your body temperature. But when sweat simply drips off you and hits the floor, it can’t lower your body temperature. To reap the cooling effect of sweat, though, that salty liquid must evaporate off the skin and turn into a gas, says William Byrnes, a sweat expert at the University of Colorado…”
Sweat isn’t triggered by heart rate or movement, but by receptors in the hypothalamus area of the brain. Individuals living in hot and humid environments will adapt to the weather, just as people aerobically trained will sweat more and sooner. The body welcomes “adaptions that help us with heat regulation,” Byrnes explains.
Because the stink of sweat doesn’t come from the odorless, colorless liquid the body produces in an effort to cool the skin, but rather from contact with bacteria present on the body, we have to combat it from all angles. With this bacteria concentrated in the armpit, applying a powerful deodorant to that specific area, instead of rubbing it all over, proves the most effective way to combat B.O…”

SWEAT SPOTS: Exercise clothing TIPS for those who SWEAT a lot!
“Published on Oct 7, 2011
**HEY, SUBSCRIBE & RATE THIS!** Just a few tips on what I have found to work me (being that I am someone who sweats profusely during exercise), in terms of clothing material to purchase (stay away from 100% cotton, however nylon & spandex work great!).
Wicking fabric is a must, just be sure to check the labels of the workout gear you’re thinking of purchasing. Just because it is sold as fitness gear, does not mean that it will provide the wicking effect you need if you tend to sweat a lot!
If you have a brand you recommend, please do share!”

“…Bamboo pulp yields a natural fabric that’s light, breathable, and moisture-wicking—it also protects your skin from ultraviolet rays. “It feels insanely soft, repels odors, regulates your temperature, and is UPF 50+,” says Tasc Performance designer, Sarah Chase. Tasc Performance and other brands blend chemical-free bamboo with organic cotton, wool, and spandex to make workout clothes l..
…A recent Belgian study found that it gives off less post-workout stench than polyester because synthetic fabrics allow stink-causing bacteria to thrive. But don’t head to spin class in a cotton tee just yet. Cotton absorbs moisture, potentially making you feel like a dishrag during a hard-charging workout. Still, for yoga, weight training, or other low-sweat activities, go with clothes made from cotton blends”..
Famously used to make women’s stockings, the synthetic fabric is soft as silk, mildew resistant, and dries quickly. It’s also breathable and wicks sweat from your skin to the fabric’s surface, where it can evaporate.You’ll find nylon in all kinds of sportswear, ..
Polyester’s main drawback: the stink factor. Synthetic material can foster bacteria growth, and it also doesn’t dry quite as quickly as polypropylene or nylon….
But unlike polyester, this synthetic material is totally water-resistant, says Lauren Hallworth, product line manager for Brooks Running apparel. “Even if you’re sweaty after a run and the outside of the shirt is wet, what’s touching you is completely dry,” says Hallworth. “It’s great as a base layer.” Polypropylene forces moisture to pass through its fibers, expelling it to the fabric’s surface where it can evaporate. ..

10 Winter Running Essentials by Jeff Laboon mensfitness.com
All the running gear to keep you warm and dry on your winter runs—”Baby, it’s cold outside,” won’t stand as an excuse not to go.
The Adidas Sequencials Half-Zip Long Sleeve Tee doesn’t just offer a mock turtleneck to protect your neck and trap body heat from escaping. Made with a spandex-type blend, its material allows for full range of motion while also keeping you cool and dry between your base and jacket. What’s more: The zipper and mesh side panels allow for extra ventilation without sacrificing body heat. Get it in grey or “infrared,” an orangish color that will shine bright on the darkest of runs. ($60, adidas.com)
Though they may not leave much to the imagination, a pair of tights must be in your running wardrobe. Period. Because just like the upper body, you want a compression layer touching the skin that can easily wick away sweat. Under Armour’s ColdGear Action Leggings are a modest set of tights made from nylon, polyester, and elastane, and paired with some synthetic underwear, they’ll keep you cool and dry. Trust us, if there’s one part of the body you want to keep comfortable on a freezing run, it’s your, lower body. Your girlfriend/wife will thank you. ($50, underarmour.com)
Running in the right sock (or wrong sock) can make all the difference in your winter workout. You want a moisture-wicking sock that’s thick and warm enough to prevent frostbitten toes, but that isn’t too bulky to cram into your shoe. The Smartwool PhD Toe Sock Mini controls the temperature in your feet and blocks the bacteria that make them reek. Its individual toes are intended to prevent blisters, and even though they’re partially made of merino wool, these socks won’t itch—promise. They cover the balls of your feet to ensure there isn’t a slit …”

GORE-TEX® and WINDSTOPPER®: What’s the difference? inspiration.goreapparel.com
A Study Program for curious minds and serious athletes
“..Here’s a new term to learn: expanded polytetrafluoroethylene (ePTFE). The GORE-TEX® membrane found in both GORE-TEX® and WINDSTOPPER® is an extremely thin layer of expanded polytetrafluoroethylene (ePTFE). It has over 9 billion pores per square inch–these pores give the GORE-TEX® fabric its amazing characteristics.
What are those characteristics? To sum it up short and sweet: WINDSTOPPER® products are windproof, breathable and WATER RESISTANT, while GORE-TEX® products are windproof, breathable and WATERPROOF. As you can see, the real difference lies in the waterproofness.
As a visual aid, take look at these jackets from our GORE BIKE WEAR® ELEMENT collection to learn more about the characteristics of GORE-TEX® and WINDSTOPPER®:..”
Eccrine glands control body temperature and are concentrated on our foreheads, underarms, soles and palms. They release sweat with little odour, mostly composed of water, salt and other trace minerals such as calcium and potassium.
Apocrine glands are found mostly around the armpits, lower abdomen and genitals. Their purpose is to excrete wastes (mostly fats and proteins) from the body. Although this sweat also has little odour itself, bacteria on the skin feed on it and produce malodorous waste products such as androstenes and isovaleric acid. The process takes about 20 minutes.
Studies show that women find fresh male sweat reasonably pleasant, but the chemical compounds that result from its breakdown highly unpleasant…”

The General Adaptation Syndrome: Applications for Sports Training sports-training-adviser.com
“..In the 1930s, Hans Selye first described the General Adaptation Syndrome (GAS) as the predictable way in which the body restores itself to balance, or homeostasis, in response to stress. … Around the same time exercise physiologists began exploring adaptations taking place due to different forms of training stresses…
The General Adaptation Syndrome has three distinct stages:
The Alarm Stage, or alarm reaction stage, is the initial response when stress is first recognized. This fight or flight response is a very quick hormonal response that served to help animals survive in the face of danger since ancient times.
We might respond to narrowly missing a serious car accident in the same way. Our bodies immediately release hormones, including cortisol, adrenaline and noradrenaline to provide instant energy. Adrenaline immediately raises the blood pressure and heart rate. When the stress is removed, the body returns to normal state of homeostasis.
The Resistance Stage, or adaptation stage, occurs if the stress continues or recurs for a period of time. In this stage, the body makes adjustments in its structures or enzyme levels to give it added protection against this specific type of stress. Rest must occur in order for recovery and rebuilding to take place.
The type of training the athlete performs determines the type of protein synthesized during recovery. This is the reason for “specificity” of the adaptive response to training. A speed training session will mobilize the energy, building projects and immune responses in the cells and tissues involved in producing speed. The stimulation of these reserves during a speed training session will dictate the type of structural changes during recovery to make the cell stronger for the next speed training session.
Mobilization of the immune system strengthens the defense capacity of the body and stimulates the repair process by dismantling and rebuilding damaged cells. The immune system plays a critical role in the outcome of the response to training.
The Exhaustion Stage occurs when long-term stress is not removed. At this point the athlete becomes fatigued and irritable. The body runs out of reserve energy and stress takes its toll on the athlete’s mental, physical, and emotional abilities. When excessive long-term stress persists, as in the case of overtraining, the athlete is unable to function and is forced to take time for recovery….”

The Body’s Fuel Sources
This is an excerpt from Endurance Sports Nutrition, Third Edition by Suzanne Girard Eberle.
The Body’s Fuel Sources
Our ability to run, bicycle, ski, swim, and row hinges on the capacity of the body to extract energy from ingested food. As potential fuel sources, the carbohydrate, fat, and protein in the foods that you eat follow different metabolic paths in the body, but they all ultimately yield water, carbon dioxide, and a chemical energy called adenosine triphosphate (ATP). Think of ATP molecules as high-energy compounds or batteries that store energy. Anytime you need energy—to breathe, to tie your shoes, or to cycle 100 miles (160 km)—your body uses ATP molecules. ATP, in fact, is the only molecule able to provide energy to muscle fibers to power muscle contractions. Creatine phosphate (CP), like ATP, is also stored in small amounts within cells. It’s another high-energy compound that can be rapidly mobilized to help fuel short, explosive efforts. To sustain physical activity, however, cells must constantly replenish both CP and ATP.
Our daily food choices resupply the potential energy, or fuel, that the body requires to continue to function normally. This energy takes three forms: carbohydrate, fat, and protein. (See table 2.1, Estimated Energy Stores in Humans.) The body can store some of these fuels in a form that offers muscles an immediate source of energy. Carbohydrates, such as sugar and starch, for example, are readily broken down into glucose, the body’s principal energy source. Glucose can be used immediately as fuel, or can be sent to the liver and muscles and stored as glycogen. During exercise, muscle glycogen is converted back into glucose, which only the muscle fibers can use as fuel. The liver converts its glycogen back into glucose, too; however, it’s released directly into the bloodstream to maintain your blood sugar (blood glucose) level. During exercise, your muscles pick up some of this glucose and use it in addition to their own private glycogen stores. Blood glucose also serves as the most significant source of energy for the brain, both at rest and during exercise. The body constantly uses and replenishes its glycogen stores. The carbohydrate content of your diet and the type and amount of training that you undertake influence the size of your glycogen stores…”

General Training Principles
Sports Training Principles sports-training-adviser.com
“..The commonly known training principles (Specificity, Overload, and Recovery) are heavily grounded in exercise physiology–the study of the effects of exercise on the human body. However, other sport sciences also support these principles.
For example, the Specificity Principle concerns how the athlete’s body adapts to the stress placed on it. Specificity also applies to practice conditions and the environment in motor learning literature.
Regardless of the fields in which they are studied, it is most important for coaches to understand how to effectively apply them in practice and competition.
While it is important to know how to use these principles, skill learning, movement mechanics, and other areas aspects of sports performance must be integrated into the programs of athletes at their respective levels of competition. ..”
