Simulated hypergravity running increases skeletal and cardiovascular loads

Article Abstract:

Eight recreational and eight competitive athletes were studied to determine the cardiovascular and musculoskeletal effects of running in hypergravity conditions stimulated by the use of lower body negative pressure (LBNP). The result showed that increased HR (heart rate) and VO2 (oxygen consumption) indicate an increased cardiovascular load whereas increased GRF (ground reaction force) indicates an increased skeletal load.

Spinal kinematics in elite oarswomen during a routine physiological "Step Test"

Article Abstract:

A study is conducted to quantify rowing technique in terms of lumbopelvic motion, force production and work done at different work intensities. The spinal kinematics of elite rowers at different incremental work intensities and noted subtle is quantified by important changes to lumbopelvic and spinal kinematics at increasing work levels, particularly at maximal intensity.

Is there an association between athletic amenorrhea and endothelial cell dysfunction?

Article Abstract:

Research shows that athletic amenorrhea is associated with the endothelium mediated dilation of the brachial artery, which may predispose female athletes to accelerated development of cardiovascular disease. Data demonstrate a reduction in the endothelium-dependent brachial artery dilation in the amenorrheic group.
