Upper limbs cycle ergometer increases muscle strength, trunk control and independence of acute stroke subjects: A randomized clinical trial.

Background: Studies demonstrate the benefits of upper limbs cycle ergometer (ULCE) in subacute and chronic stroke subjects, but the literature still needs to explore the acute phase of the disease.

Objective: Verify the effects of ULCE on muscular strength, trunk control and independence of post-stroke subjects in hospital acute phase.

Methods: In this randomized clinical trial participants were allocated into two groups.

Photobiomodulation therapy increases functional capacity of patients with chronic kidney failure: randomized controlled trial.

Photobiomodulation (PBM) has been used in different populations as a strategy to attenuate muscle fatigue and improve exercise performance. Recent findings demonstrated that a single session with specific PBM doses during hemodialysis (HD) increased the upper limb muscle strength of chronic kidney failure (CKF) patients. Now, the primary objective of this study was to evaluate the chronic effect of PBM on the functional capacity of this population.

Aerobic training reduces oxidative stress in skeletal muscle of rats exposed to air pollution and supplemented with chromium picolinate.

Objective: The purpose of this study was to investigate the effects of chromium picolinate (CrPic) supplementation associated with aerobic exercise using measures of oxidative stress in rats exposed to air pollution.

Methods: Sixty-one male Wistar rats were divided into eight groups: residual oil fly ash (ROFA) exposure and sedentary (ROFA-SED); ROFA exposure, sedentary and supplemented (ROFA-SED-CrPic); ROFA exposure and trained (ROFA-AT); ROFA exposure, supplemented and trained (ROFA-AT-CrPic); sedentary (Sal-SED); sedentary and supplemented (Sal-SED-CrPic); trained (Sal-AT); and supplemented and trained (Sal-AT-CrPic). Rats exposed to ROFA (air pollution) received 50 µg of ROFA daily via intranasal instillation.
