Answer:
Running events range from 60-m sprints to ultra-marathons covering 100 miles or more, which presents an interesting diversity in terms of the parameters for successful performance. 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. To create this high force output, sprint events rely heavily on anaerobic metabolism, as well as a high number and large cross-sectional area of type II fibers in the leg muscles. Middle distance running performance is characterized by intermediates of biomechanical and physiological parameters, with the possibility of unique combinations of each leading to high-level performance. The relatively fast velocities in mid-distance events require a high mechanical power output, though ground reaction forces are less than in sprinting. Elite mid-distance runners exhibit local muscle adaptations that, along with a large anaerobic capacity, provide the ability to generate a high power output. Aerobic capacity starts to become an important aspect of performance in middle distance events, especially as distance increases. In distance running events, V˙O2max is an important determinant of performance, but is relatively homogeneous in elite runners. V˙O2 and velocity at lactate threshold have been shown to be superior predictors of elite distance running performance. Ultramarathons are relatively new running events, as such, less is known about physiological and biomechanical parameters that underlie ultra-marathon performance. However, it is clear that performance in these events is related to aerobic capacity, fuel utilization, and fatigue resistance.
Explanation:
Answer: To increase arterial pressure you need to increase the cardiac output
Explanation:
Cardiac output is the volume of blood being pumped by the heart in one minute. It is equal to heart rate multiplied by stroke volume.
Two factors affect the strength of the blood: cardiac output and peripheral resistance. Cardiac output is the volume of blood circulated by the heart. Increasing heart rate also results in increased cardiac output, which increases blood pressure.
The answer b is not true.
Answer:
Well there's no real answer as to what the meaning is but it may sound cheesy or whatever but its basically what you want it to be. If you want to live and start a company or work a 6-5 job or take a vacation. It's really up to you on how you see it and what you want the meaning to be.
Explanation:
Answer:
=NETWORKDAYS(A1,A2)
Explanation:
To use NETWORKDAYS function, we make use of the syntax:
= NETWORKDAYS(begin_date,end_date,[holidays])
The argument in square bracket is optional.
Assume that cell H5 is the initial date and cell H6 is the final date, the above syntax will be implemented as:
=NETWORKDAYS(H5,H6)
