Methods: This was a randomized, counterbalanced crossover study. Fifteen Division 1 collegiate basketball players y consumed 6. Blood perfusion total hemoglobin and oxygen saturation of frontal brain were continuously measured by near-infrared spectroscopy during the cycling.

Whether protein supplementation enhances these adaptations remains unclear. Objective: The present study was designed to determine the impact of protein supplementation on changes in VO2max during prolonged endurance training.

Methods: We used a double-blind randomized controlled trial with repeated measures among 44 recreationally active, young males. Subjects performed 3 endurance training sessions per week for 10 wk.

The VO2max, simulated km time trial performance, and body composition dual-energy X-ray absorptiometry were measured before and after 5 and 10 wk of endurance training. Fasting skeletal muscle tissue samples were taken before and after 5 and 10 wk to measure skeletal muscle oxidative capacity, and fasting blood samples were taken every 2 wk to measure hematological factors.

Determinants of Maximal Oxygen Consumption

The muscle fiber type also will influence both the ability of the muscle to be aerobically trained and the resultant maximum oxygen consumption.

Type I, or slow twitch, fibers are naturally endowed with more oxidative aerobic enzymes and mitochondria, the place in the cell where aerobic metabolism takes place. They also have more capillaries per fiber area and as a result can supply more oxygen to the muscle fiber.

Type II muscle fibers are less well adapted for aerobic work but can still be trained to augment key aerobic enzymes. They also have a reduced capillary to fiber area ratio. This is not a discussion of muscle fiber types, and has been vastly oversimplified.

Therefore, the larger the mass of exercising, trained, type I muscle, the greater will be the oxygen utilization on a whole body level. This figure is important in sports where movement of the body against the force of gravity is of little consequence.

Facilities like ours at NISMAT have the ability to directly measure oxygen consumption while a person is exercising. A person wears headgear which contains a non-rebreathing valve which the person holds in the mouth, like a snorkel. Room air is inhaled through the valve and air which is exhaled goes through a tube into a metabolic measurement cart.

The cart measures the amount of oxygen and carbon dioxide in the exhaled air, as well as the volume of air. Knowing that room air contains The test consists of a person walking or running on a treadmill, pedaling a stationary cycle ergometer, rowing on an ergometer or hand cranking an upper body ergometer.

The intensity of the work increases on a regular basis, usually every one or two minutes and continues until the subject can go no further. A true maximum effort is difficult and takes a great deal of motivation from both the person administering the test and the subject; it is also important to have proper resuscitative equipment and personnel on hand in the even that the subject has a problem during the test.

The best indicator of a maximal effort occurs when the work rate increases but oxygen consumption does not increase over the previous work rate. Good tests of maximum oxygen consumption take about minutes of exercise.

Many facilities like health clubs determine oxygen consumption by estimating it. Since work rates on a treadmill or bicycle are known, and average oxygen costs for maintaining these work rates have been measured, one can apply these equations and estimate maximum oxygen consumption.

As shown in the graphs below, there are well-known relationships between neart rate and VO2 max and work rate and VO2 max. These are imprecise measurements and subject to a great deal of subject variability with respect to how efficiently a person exercises as well as measurement error associated with inaccurate calibration of the exercise equipment.

Exercising harder, more frequently, and longer will boost that increase up a little as well. Yes, even highly motivated individuals who train diligently are unlikely to attain the high values mentioned above in elite runners.

However, few people ever train hard enough to achieve their genetic potential. While HIIT or heavy resistance training is effective and beneficial, remember to allow at least 48 hours of recovery time between high-intensity exercise sessions and try to limit yourself to no more than three strenuous workouts per week.

If you do start increasing the intensity of your workouts to boost EPOC, consider adding these recovery strategies. Bersheim, E. and Bahr, R. Effect of exercise intensity, duration and mode on post-exercise oxygen consumption.
