"increased exertion" is correct and usable in written English.
You could use it to describe a situation that involves putting forth more effort, energy, and/or strength to achieve a goal. For example, "With increased exertion, he was finally able to lift the heavy box."
We previously reported that with a backpack load within 15% body weight (BW), young adults maintain their gait parameters at the expense of increased exertion during a 6-minute walk at self-selected normal walking speed.
However, we were unable to describe the trajectories that showed an increase in fatigue over time (increased exertion fatigue with mild offset, increased exertion fatigue with moderate offset, and increased general fatigue with mild offset).
The exertion fatigue classes had the following event rates: reference group (18.8%, n = 18), low exertion fatigue (2.6%, n = 1), mild exertion fatigue (14.7%, n = 10), increased exertion fatigue with mild offset (15.0%, n = 3), increased exertion fatigue with moderate offset (15.4%, n = 8), and severe exertion fatigue (28.6%, n = 10).
Regardless of the method, the normal response to an exercise stress test is measured as elevations in HR and blood pressure (BP) that are proportional to the increased exertion, which also then reflects in the expected recovery at cessation.
Moreover, it is important to determine whether butorphanol combined with oxygen insufflation has the same positive effect on immobilization-induced hypoxaemia in field-immobilized white rhinoceros where increased exertion and other variables may alter individual responses.
However, Bidlack adds that athletes require extra calories to provide energy for increased exertion, and extra water to compensate for heat-related fluid loss.
After a while, one became aware, as well, of the pungent result of increasing exertion.
In athletes, IL-6 receptor production increases with increasing exertion, and having more receptors raises sensitivity to IL-6 and triggers fatigue.
The player is then required to go through several steps of increasing exertion: a stationary bicycle, jogging, agility work and noncontact team drills.
The focus of this study was the possibility that increasing exertion could improve the voice and might result in the voice user experiencing less strain and, therefore, more comfort and ease.
An athlete can adjust training by breathing more deeply, increasing exertion to hit a target heart rate, or focusing on reducing stress in competitive situations (Kooser 2014).
