how to measure maximal aerobic capacity
- best accuracy is done in a lab - measures precise amount of oxygen entering and exiting the body suring teh exercise session
exercise

Using the American College of Sports Medicine (ACSM. and the National Athletic Trainers' Association (NATa. recommendations, calculate the amount of fluid an athlete weighing 200 pounds needs to consume 4 hours prior to vigorous training in order to remain adequately hydrated.Answer: The ACSM and the NATA guidelines call for athletes to consume approximately 0.7 to 1.07 ounces of fluid per 10 pounds of body weight 4 hours prior to exercise. For an athlete weighing 200 pounds, the calculation is as follows: First, divide 200 pounds (the athlete's total weight. by 10 pounds (the unit of weight used to calculate fluid ounces.: 200/10 = 20. Next, multiply 0.7 ounces X 20 units (of 10 pounds each. = 14 ounces Finally, multiply 1.07 ounces X 20 units (of 10 pounds each. = 21.4 ounces. An athlete weighing 200 pounds should drink 14 to 21.4 ounces of fluid 4 hours before training.
