What is cardiorespiratory  fitness? Refers to the ability to perform large  muscle, dynamic, moderate-to-high  intensity exercise for prolonged periods. It reflects the functional capabilities of the  heart, blood vessels, blood, lungs, and  relevant muscles during various types of  exercise demands.

What is it meant to be physically fit? The ability to perform moderate-to-vigorous  levels of PA without undue fatigue and the  capability of maintaining this capacity  throughout life   (Pollock, 1998).

What is it meant to be  physically fit? “A set of attributes that people have or  achieve that relates to their ability to  perform physical activity   (USDHHS, 1996) .” “A state of well-being with low risk of  premature health problems and energy to  participate in a variety of physical activities   (Howley & Franks, 1997) .”

Question? Quantity of exercise, how much exercise is  enough for  health/fitness  benefits? Quantity and quality  (esp. with regards to  intensity) of PA to attain health  benefits  (including degenerative diseases, e.g.  osteoporosis, and chronic diseases, e.g.,  diabetes and cardiovascular disease) is much  lower  than the  quantity and quality  required to  attain fitness  benefits (including an increase in  VO2max). VOLUME of ex is a function of Freq. intensity,  and time (duration). There is a dose-response  (minimum and maximum amount) relationship  for the volume of exercise necessary for H/F  benefits. Even small increases in caloric expenditure may  improve H/F outcomes with the greatest benefit  accruing in sed. folks
