Effects of Creatine Supplementation on the Myostatin Pathway and Myosin Heavy Chain Isoforms in Different Skeletal Muscles of Resistance-Trained Rats.

Creatine has been used to maximize resistance training effects on skeletal muscles, including muscle hypertrophy and fiber type changes. This study aimed to evaluate the impact of creatine supplementation on the myostatin pathway and myosin heavy chain (MyHC) isoforms in the slow- and fast-twitch muscles of resistance-trained rats. Twenty-eight male Wistar rats were divided into four groups: a sedentary control (Cc), sedentary creatine supplementation (Cr), resistance training (Tc), and resistance training combined with creatine supplementation (Tcr).

Effectiveness of aquatic exercise in the treatment of inflammatory arthritis: systematic review.

Spondyloarthritis and rheumatoid arthritis are classified as inflammatory arthritis and represent a significant source of pain and disability. Non-pharmacological intervention with physical exercise is among the therapeutic approaches most used by health professionals. This study aimed to investigate the effectiveness of aquatic exercise in the treatment of inflammatory arthritis.

Acute effects of different rest intervals between agonist-antagonist paired-sets in the neuromuscular system performance of young adults.

Introduction: The agonist-antagonist paired-sets (APS) is a resistance training that involves alternating between exercises for agonist/antagonist muscles of a joint, with little or no rest between then. There is evidence that APS is more strenuous than traditional methods, but evidence on the optimal RI between agonist-antagonist actions is unknown.

Objective: The aim of this study was to compare different rest intervals between agonist-antagonist actions during APS in young adults.

The Torque Referenced to a Perceived Exertion Level Is Affected by the Type of Movement in Men With Spinal Cord Injury.

Objectives: To compare a standardized submaximal intensity (based on the rate of perceived exertion [RPE]) with the percentage of the average and peak torque during a familiarization session in individuals with different spinal cord injury (SCI) levels in gravity-resisted and gravity-assisted movements.

Methods: This was a cross-sectional study at a rehabilitation hospital. Thirty-six individuals stratified in tetraplegia (TP), high paraplegia (HP), and low paraplegia (LP) groups and 12 matched control participants (CG) were enrolled in the study.

Epidemiological profile of soccer-related injuries in a state Brazilian championship: An observational study of 2014-15 season.

Background: Soccer related injuries are often reported in studies, but epidemiological research on this theme is rare in Brazil, Furthermore, the conditions in which athletes have returned to sports practice, namely, either symptomatic or asymptomatic, have been neglected in research.

Objectives: The aim of this study was to describe the epidemiological features of injuries among professional Brazilian soccer players in relation to location, type, mechanism, severity, recurrence, treatment and, lastly, symptoms in return to sport.

Study Design: Descriptive and cross-sectional, observational study.
