Under normal physiological conditions, cells are highly efficient at maintaining steady state. However, under conditions of physiological stress, such as hypoxia (reduced oxygen supply) caused by ischemia or strenuous exercise, the energy balance can be disrupted and the functional integrity … Continue reading →

Static Exercise Isometric contractions are usually held for 6 to 10 seconds and require a minimum exertion of two thirds maximum force. Maximum exertions produce greater results than sub-maximum efforts. A total contraction time of 30 seconds of applied force … Continue reading →

The branched-chain amino acids (leucine, isoleucine, and valine) are the major ones … Continue reading →
