Chemistry
The body is full of complex biochemical reactions taking place from moment to moment even at rest. These are as important as our structure for optimal endurance. These chemical activities have specific effects on other aspects of our body chemistry and on our structural and mental state. For example, the wide-ranging effects of many of the body’s hormones, including testosterone and growth hormone, influence our training. The reverse is also true, as these hormones are also influenced by our physical training. These actions control physical muscle development, the chemical reactions that supply energy, and the body’s natural anti-inflammatory chemicals, which promote recovery. These changes also influence our mental state.
Consuming different types of foods can also produce various effects on the body, which influences endurance. This takes place in the brain, muscles, intestines, and other areas. For example, a meal of highly refined carbohydrates, such as pasta, pancakes, or cereal, before training or competition can have an adverse effect on the use of fats for energy and endurance. Or, going on a diet to lose weight can result in structural changes in muscles that can cause an injury or a stress fracture in a bone. Caffeine and other popular drugs, such as NSAIDs (non-sterosidal anti-inflammatory drugs), affect the body in ways that can help or hurt endurance, too. Even the brain’s delicate chemistry can influence our muscle function, hormones, and our thought processes through the balance of chemical messengers called neurotransmitters.
