The Effect of A Flywheel Hip Extension Vs A Traditional Hip Extension Exercise on Hamstring Strength

International Journal of Strength and Conditioning
The 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.

THE REDUCTION OF VIBRATIONS IN A CAR – THE PRINCIPLE OF PNEUMATIC DUAL MASS FLYWHEEL [PDF]

Scientific Journal of Silesian University of Technology. Series Transport, 2014
The dual-mass flywheel replaces the classic flywheel in such way that it is divided into two masses (the primary mass and the secondary mass), which are jointed together by means of a flexible interconnection. This kind of the flywheel solution enables

Microgravity‐induced changes in skeletal muscle and possible countermeasures: What we can learn from bed rest and human space studies

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 ...

Performance, cardioventilatory and perceptual responses to perceived opponent ability during head‐to‐head cycling competition

Experimental Physiology, EarlyView.
Abstract We aimed to investigate whether cycling competition influences performance and pacing compared to an individual time trial. The second aim was to determine whether performance is further influenced by deceptive or accurate augmented feedback, delivered as an opponent riding at 2% higher power outputs than a previous competitive time trial ...
