The aims of this study were to investigate the sarcomeric accumulation and expression of heat shock proteins (HSPs) after two bouts of maximal eccentric exercise. Twenty-four subjects performed two bouts of 70 maximal voluntary eccentric actions using the elbow flexors in one arm. The bouts were separated by 3 wk. The changes in concentric (60 degrees/s) and isometric (90 degrees) force-generat...

The present research attempts to ascertain the impact of immediate verbal feedback (IVF) on modifications of stroke length (SL). In all swimming styles, stroke length is considered an essential kinematic parameter of the swimming cycle. It is important for swimming mechanics and energetics. If SL shortens while the stroke rate (SR) remains unchanged or decreases, the temporal-spatial structure ...

Actinomycosis of the tonsillar tissue is a rare pathological condition whose clinical significance has been disputed over by authors worldwide. We report a case of Actinomycosis of the tonsils in a young boy with symptoms of chronic tonsillitis. We believe that the infection would have been the cause of repeated bouts of sore throat in the patient leading to chronic tonsillitis and tonsillar at...

Hatchling sea turtles emerge from nests, crawl down the beach and enter the sea where they typically enter a stereotypical hyperactive swimming frenzy. During this swim the front flippers are moved up and down in a flapping motion and are the primary source of thrust production. I used high-speed video linked with simultaneous measurement of thrust production in tethered hatchlings, along with ...

BACKGROUND The primary analysis in a longitudinal randomized controlled trial is sometimes a comparison of arms at a single time point. While a two-sample t-test is often used, missing data are common in longitudinal studies and decreases power by reducing sample size. Mixed models for repeated measures (MMRM) can test treatment effects at specific time points, have been shown to give unbiased ...

The different characteristics of the four swimming strokes affect interplay between limbs, acting as a constraint to force produced by each hand and foot. purpose this study was analyze symmetry production with varying number limbs in action see its effect on velocity. Fifteen male swimmers performed all-out bouts 25-m swims full-body stroke segmental actions. A differential pressure system use...
