Quick fact. Ready? When exercising at higher intensities, one often begins to feel fatigued even once half of intramuscular glycogen stores have been depleted. Higher carb diets may help to delay this fatigue by replenishing these muscular energy storages.

Quick fact. Ready? During physical activity, there is a whole bad vasoconstriction, EXCEPT for at the working muscle itself. This dilation at the active muscles is caused by the metabolites released during contraction, and helps to redirect blood flow towards them.

Quick fact. Ready? One should notice performance improvements even within the first week after beginning aerobic/endurance training. Training affects occur fairly quickly. However, detraining occurs just as quickly with such aerobic activities.

Quick fact. Ready? Endurance training for a minimum of 5-6 hours every week can result in a physical enlargement of the heart itself known as Athlete's Heart Syndrome. The increase in size allows for the heart to pump out more blood with every beat, making it more efficient. This is the body's way of adapting to the increased oxygen demand being put on it during prolonged aerobic training. Now, who wouldn't want a bigger heart?

Quick fact. Ready? The intensity of a specific activity can often be conveyed through way of METS (Metabolic Equivalents). These are expressed in relation to one's Basil Metabolic Rate, which is why Exercise machines ask to input one's weight prior to exercise.

Quick fact. Ready? Heart Rate Variability (HRV) is a measure of the balance between one's Sympathetic and Parasympathetic signals to the heart. High HRV is healthy, and indicates that the body is readily able to react to external stimuli.

Quick fact. Ready? The Psoas Major Test is a clinical method of checking for any inflammation of the Abdominal organs. Testing positive involves pain during extension of the hip, which then resides during flexion. This is strange, for the pain of the organs is transferred to the near by hip extenders.

Quick fact. Ready? There is a certain point during increasing intensity exercise, known as ventilatory threshold, in which breathing rate increases above and beyond the intensity of work that is actually being performed. This is due to a huge increase in cars on dioxide production.

Quick fact. Ready? Exercising with a particular muscle group only uses up the glycogen stored in those being used. The glycogen in all other unused muscle groups remains the same.
