A person’s maximal oxygen uptake (V02 max), also commonly referred to as aerobic capacity, is determined in a laboratory by measuring how much oxygen a person can use in one minute of maximal exercise. Great endurance athletes can extract five or six liters of oxygen per minute from the environment during an all-out treadmill run or bicycle ride. An average person extracts only two or three liters in a une minute exercise bout. V02 max is often adjusted to account for a person’s body size since bigger people may have higher scores because of their larger size. Scores are often reported as milliliters of oxygen per kilogram of body weight (m1/O2/kg). This score is calculated by dividing your VO2 max value by your weight in kilograms.
Aerobic exercise is the most effective means of improving VO2 max.
As noted previously in this concept, good cardiovascular fitness requires a fit heart muscle, fit vascular and respiratory systems, fit blood, and fit muscles. Regular aerobic exercise improves these systems, which are essential for improved max VO2. (more…)

There are several good PRE programs for strength development, each having advantages and disadvantages.
Progressive resistance exercise can be performed in properly designed weight-training programs using free weights, constant resistance machines, variable (accommodating) resistance machines, isometrics, pulleys, calisthenics, springs, latex tubing, or isokinetic dynamometers. Machines may offer resistance by weight stacks, hydraulic or pneumatic pressure, or electrical resistance. Concept 12 describes some sample exercises and compares some of these programs. Weight training is considered the fastest and best method of improving strength. However, properly designed calisthenics are adequate for developing strength in most people. (more…)

Exercise adherence means regular lifetime exercise. Positive addiction is another term commonly used to describe this healthy life-style. The implication is thatexercise is addicting, but unlike addictions such as drugs and smoking, the consequences of the addiction are positive. Experts have not established that exercise can be addicting, though it is generally agreed that some people develop very strong exercise habits (exceptional adherence) even to the point of exercise neurosis. Habitual exercisers regularly indicate that they have positive feelings, even feelings of euphoria, when they do regular, sustained exercise. (more…)
