PET 3351 Exercise Physiology Second Exam Review (Fall 2012) Chapter IV: The Physiological Basis of Muscular Strength and Flexibility 1. Strength is operationally defined as the maximal force that can be exerted in a single effort. Using this definition‚ strength should be assessed using one repetition maximum (1 RM)‚ though we often estimate strength using tests that may involve multiple repetitions. 2. In strength training and rehabilitation‚ emphasis should be given to both the concentric

It has 15 g of Carbohydrates which is the body’s main source of energy. It is also primary fuel source for muscles which are working at a moderate to high intensity and prolonged endurance. 2. It has sodium‚ potassium‚ calcium and magnesium which replenish the electrolytes commonly lost through sweat

The tetrazolium test indicates the presence of redox reaction‚ which signifies metabolic activity by turning samples that perform metabolism a pink color. Sucrose was used as a control to show that the test is accurate in that it does not turn samples that do not perform metabolism pink. Sucrose was not turned pink‚ which validates the accuracy of the tetrazolium test. As expected‚ samples ALV-882-21 and ALV-694-02 did not turn pink; the Feulgen’s/Schiff’s

the air‚ through the circulatory system throughout which metabolism uses oxygen to convert these nutrients into ATP for energy use (Johnson 1980). When an organism is experiencing starvation it is not receiving enough nutrients to support the normal rate of ATP and hence energy production and so slows all metabolic processes in the body in order to preserve energy for survival (Jacobstein and Gerken‚ 1989). With the decreased rate of metabolism there is less demand for oxygen and so the rate of oxygen

How the body achieves homeostasis of the internal fluid environment through excretion of waste products of metabolism. Hint: Relate this to lung and kidney functions. 3. The role of the endocrine system in cellular metabolism (Give 2 examples) 4. Give 2 examples of abnormal growth (Hint: overweight/obesity; underweight)

This allows you to increase your metabolism‚ lose weight naturally and simultaneously feel better. By losing weight‚ you can increase your metabolism‚ weight loss and lose weight effectively and naturally effective. Learn more in this article and learn more. What is spirulina?

The first half of module seven discussed protein digestion‚ absorption‚ and metabolism; while the second half focused on pathological stress and kidney disease. Protein digestion occurs in the stomach and small intestine. When a protein reaches the stomach it is denatured by hydrochloric acid. Once the protein is digested pepsin breaks apart the denatured protein into peptides. Peptides move into the small intestine where they encounter an enzyme that digest the peptides into di- or tripeptides‚

The liver produces bile‚ which helps digestion and absorption of dietary lipids. The pancreas produce molecules and enzymes which also help digestion. G. Chemical homeostasis is crucial to maintaining a healthy body. For example‚ when the pH levels in Eugene’s blood were off‚ it caused problems in his body. Investigating his
