11 cze 2020 · Most of the studies published to date have shown that the performance in short-duration maximal exercises (i.e. less than 1 min - e.g. sprints, jumps, isometric contractions) exhibits diurnal...
27 lis 2010 · So the brain will, for example, detect the rate of heat storage early on and then reduce the exercise workrate through adjustments in muscle activation, the result of which is a slowing in pace, but also a drop in heat storage and avoidance of that limiting body temperature.
2 sie 2017 · Here, we review the physiological and biomechanical variations underlying elite human running performance in sprint to ultramarathon distances. Maximal running speeds observed in sprint disciplines are achieved by high vertical ground reaction forces applied over short contact times.
In the present review, time-of-day and chronotype effect on HRV in response to acute sessions of physical activity are discussed.
10 mar 2024 · Men usually have the upper hand, thanks to more muscle mass, higher testosterone, and body composition that favors speed. Elite male sprinters can dash over 37 km/h (about 23 mph), while top female sprinters are not far behind, reaching speeds around 33 km/h (roughly 20.5 mph).
The analysis of the results shows an important improvement in the capacity of predicting short trail running performance, with the innovative feature of this study being the inclusion of the variable percentage fat mass.
Heart rate recovery (HRR) after strenuous exercise has been shown to be faster (i.e., heart rate decreases more quickly) among individuals with higher levels of fitness and after aerobic training programs in a variety of adult and pediatric populations (13,24,30,33).
