Bone density in elite judoists and effects of weight cycling on bone metabolic balance

Article Abstract:

A study examines potential disrupter and stimulators of bone integrity through an analysis of bone parameters at baseline and the effects of the first weight cycle of the season on bone metabolic status in 48 male and female elite judoists. It is observed that elevated bone formation rate pertaining to judo athletes lent protection from alterations in bone metabolic balance with weight cycling, suggesting that powerful osteogenic stimuli provided by judo's unique biomechanical environment might help prevent bone loss associated with weight loss.

Exercise and vasorelaxing effects of CO-releasing molecules in hypertensive rats

Article Abstract:

A study investigates the effects of exercise training on the rat thoracic aorta (TA) responsiveness to a carbon monoxide-releasing molecule (CORM), tricarbonyldichlororuthenium. Results indicate that the exercise training improves the aorta's ability to relax in response to the CORM during hypertension, probably by increasing potassium K(super +) channel activity.

L-citrulline reduces time to exhaustion and insulin response to a graded exercise test

Article Abstract:

A study aims to determine whether time to exhaustion during a graded treadmill test, as well as plasma insulin and glucose profiles, could be improved with oral L-citrulline supplementation in healthy individuals. Results show a reduction in treadmill time following L-citrulline ingestion over the 24 hours prior to testing.
