Exercise physiologists say there are three components to great running: A high VO2 max, the volume of oxygen an athlete can consume at maximum exertion; great running efficiency, a measurement of the energy used to run at a particular pace; and an ability to keep going at a high level of exertion for a long time, expressed as the percentage of VO2 max that can be sustained during a run.
Tracking a player's heart rate allows the team to see, among other things, at what points and during which drills a player is at maximum exertion, and how often he reaches that point.
Thus despite a reduced cardiac output at maximum exertion at altitude in our study, there was still no demonstrable increase in whole body oxygen extraction.
Patients were monitored for heart rate, blood pressure, rhythm, symptoms, ECG changes and rate of perceived exertion (on a 1 10 scale, where 10 is maximum exertion) at rest and at every stage of the exercise protocol.
In view of the reduced work rate at maximum exertion at high altitude a comparison was made between mean C(a−v O2 for peak exertion at high altitude and the equivalent V ˙ O 2 at sea level; no difference in oxygen extraction was detected.
Subjects were asked to start the pull initially with a moderate intensity and slowly increase the intensity to maximum exertion while keeping the trunk extended to prevent muscle injuries.
However, considering that the form and function of the respiratory system may be adjusted to the demands of maximum exertion [37], maximal metabolic rate (MMR) may represent a more appropriate measure of metabolic demand.
Sometime Death will pick out a man with the muscles of a superhero, pick him out in repose, perhaps, or in his moment of maximum exertion, when his thighs and shoulders are trembling and he feels most alive.
This is most likely to happen if people do not breathe properly in a workout (the breath should never be "held"; rather, one should exhale during maximum exertion and inhale when the muscles relax) or if they try to sustain a muscle contraction for too long.
It was at the point of maximum exertion that the dam burst, in every sense of the term".
Much Caribbean pop tends to groove at medium tempo, but Tabou Combo can play fast and furious, inspiring dancers to maximum exertion.
