6 paź 2020 · Together VO2max and running economy determine maximal aerobic speed, which is the slowest speed at which VO 2max occurs. Maximal aerobic speed correlates with race speed on shorter distances...
16 lis 2018 · The purpose of this work is to develop a novel, minimal and universal model for human running performance that employs a relative metabolic power scale. The main component is a self-consistency relation for the time dependent maximal power output.
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.
16 maj 2014 · When humans ran against a maximum impeding force of −6% body weight, the average braking impulse decreased by 52% while the average propulsive impulse increased by 48%, resulting in a 38% increase in the net metabolic cost of running.
1 maj 2017 · It is clear that the running speed generated for a given submaximal V ˙ O 2 max can vary by 15–20%, and among relatively homogeneous groups of highly trained male runners, running economy is a definitive factor in determining race performance (Conley & Krahenbuhl, 1980; Joyner, 1991). However, less is known about the fundamental biological ...
24 wrz 2018 · Ten high-caliber male human runners ran on a force-measuring treadmill at 8, 10, 12, 14, 16 and 18 km h −1 while we analyzed their expired air to determine metabolic rates. We measured ground reaction forces and joint kinematics to calculate contact time and estimate active muscle volume.
1 gru 2009 · Abstract. The purpose of this study was to compare running economy across three submaximal speeds expressed as both oxygen cost (ml·kg −1 ·km −1) and the energy required to cover a given distance (kcal·kg −1 ·km −1) in a group of trained male distance runners.
