There is a direct linear relationship between intensity of aerobic exercise and VO 2. Our maximum intensity is a reflection of our maximal oxygen consumption (VO 2 max). Such a measurement represents a cardiovascular fitness level. [3] VO 2 is measured in METs (mL/kg/min). One MET, which is equal to 3.5 mL/kg per minute, is considered to be the ...
In the study, moderate-intensity exercise led to significant cortisol increases, while high-intensity exercise caused dramatic spikes—up to 80 percent higher than baseline.
Humans have a high capacity to expend energy for many hours during sustained exertion. For example, one individual cycling at a speed of 26.4 km/h (16.4 mph) through 8,204 km (5,098 mi) over 50 consecutive days expended a total of 1,145 MJ (273,850 kcal; 273,850 dieter calories) with an average power output of 173.8 W.

In an incremental exercise test, it is the first speed at which any increase in exercise intensity fails to elicit an increase in oxygen consumption. The vV̇O 2 max of world class middle- and long-distance runners may exceed 24 km/h or 2:30/km pace ( 15 mph or about 4:00/mile), making this speed slightly comparable to 3000 m race pace.
The relationship between stress and weight gain is complicated. ... You'll power through the day but gain weight. ... Aim for a minimum of 150 moderate-intensity exercise or 75 minutes of vigorous ...
[2] [4] Increased exercise intensity has been shown to hinder the “distraction effect” caused by listening to music while exercising. [ 5 ] This finding suggests that music can be beneficial for long durations of light to moderate intensity exercise and improve aerobic performance by “distracting” the individual exercising.
If you have neither a power meter or a heart rate monitor, you can also use your rate of perceived exertion (RPE) or the talk test to help to make sure you’re working at a high intensity ...
Other studies have shown that exercise-based rehabilitation at a moderate intensity in heart failure patients improves cardiorespiratory fitness and increases both exercise endurance capacity and VO2max (12–31% increase). [15] More recent studies have examined the effects of high-intensity exercise on patients with heart failure.
