The Effect of A Flywheel Hip Extension Vs A Traditional Hip Extension Exercise on Hamstring Strength
International Journal of Strength and ConditioningThe main aim of this present study was to compare the effect of a flywheel hip extension exercise versus a traditional gravity-dependent exercise on hamstring strength. Twenty U-20 male soccer players volunteered to participate in the study.

Experimental Physiology, EarlyView.Abstract Despite exercise countermeasures to sustain health and performance in spaceflight, complete maintenance of muscle mass and functions in microgravity is still not possible for most astronauts. The principal cause of the limited effectiveness of existing exercise countermeasures is the difficulty in achieving full loading forces in space.

Blood flow restriction exercise during microgravity exposure in parabolic flight
Experimental Physiology, EarlyView.Abstract This case report evaluates whether it is possible to perform blood flow restriction (BFR) exercise during exposure to microgravity. The objectives were three‐fold: (1) to determine if a personalised tourniquet system (PTS) hardware technology performs nominally and enables BFR exercise in microgravity; (2) to determine if BFR augments the ...

Modeling and simulation of a passive variable inertia flywheel for diesel generator
Energy Reports, 2020 The power supply system of diesel generators is isolated. Sudden loading and unloading will lead to fluctuation of the engine speed and exert an impact on the power supply quality.

Imposed expiratory resistance, dynamic hyperinflation and locomotor power and fatigue
Experimental Physiology, EarlyView.Abstract Expiratory flow limitation results in dynamic hyperinflation, dyspnoea and premature exercise intolerance. We aimed to measure whether expiratory resistance reduces locomotor power via limiting maximal voluntary motor activity, exacerbating muscle fatigue, or both.
