Type IIb fibers are known as fast-twitch glycolytic fibers. Two to three hours post-exercise blood pressure drops below pre-exercising values, this is known as "post-exercise hypotension". In summary, exercise is accomplished by alteration in the body response to the physical stress (exercise physiology). Plasma levels of cortisol, epinephrine, norepinephrine, and dopamine increase with maximal exercise and return to baseline after rest.

Exercise Physiology is the physiology of physical exercise, concerned with the way our body responds to exercise and training. Exercise physiology is helpful in understanding different kinds of exercises and the benefits the body derives from them. High blood pressure = systolic blood pressure ≥140 and/or diastolic blood pressure ≥90 mm Hg blood pressure. Endurance training increases plasma volume, which elevates the blood volume that returns to firstly the right heart and after that to the left ventricle. The end-diastolic phase is the phase in which the passive filling (diastole) of the heart finishes. the myoglobin content may sometimes increase, thus the oxygen storage capacity increases. Resistance training thus leads to greater force development of the trained muscles. It addresses the short term biological responses to the stress of physical activity and studies the acute responses and chronic adaptations to a wide range of exercise conditions. Slow-twitch fibres: The cross-sectional area of slow-twitch (AKA red) fibres increases slightly in response to aerobic work. Z)h)h����u R�@-� QKK@ KE- b�K@ KF)i b�\R��R�b��P�1N�� &(�.
