Kinesiotaping Diminishes Delayed Muscle Soreness but does not Improve Muscular Performance.

This study aimed at determining the effect of kinesio-taping (KT) on muscle performance and delayed onset muscle soreness (DOMS) after exercise induced muscle damaged. Sixty-six healthy men volunteered to participate (age:18-25 y/o), who performed 200 isokinetic lengthening contractions of the dominant quadriceps. Then subjects were randomized to either control (no treatment), sham (no tape tension), or KT (10% tape tension) groups.

Continuous Ultrasound Decreases Pain Perception and Increases Pain Threshold in Damaged Skeletal Muscle.

Objective: Determine whether therapeutic ultrasound (TUS) delivered in a continuous mode reduces pain perception after muscle injury.

Design: Randomized, double-blind trial.

Setting: Institutional laboratory.

Resveratrol improves muscle function but not oxidative capacity in young mdx mice.

Patients with Duchenne muscular dystrophy (DMD) have reduced muscle function due to chronic muscle damage, inflammation, oxidative stress, and reduced oxidative capacity. Resveratrol reduces inflammation and oxidative stress, and increases oxidative capacity in other disease models. The purpose of this study was to determine the effects of resveratrol on muscle function, muscle pathology, and oxidative capacity in young mdx mice.

Resveratrol decreases inflammation and increases utrophin gene expression in the mdx mouse model of Duchenne muscular dystrophy.

Background & Aims: Duchenne muscular dystrophy (DMD) is a lethal genetic disease with no cure. Reducing inflammation or increasing utrophin expression can alleviate DMD pathology. Resveratrol can reduce inflammation and activate the utrophin promoter.

Six1 and Six1 cofactor expression is altered during early skeletal muscle overload in mice.

Six1 is a transcription factor that, along with cofactors (Eya1, Eya3, and Dach2), regulates skeletal muscle fiber-type and development. SIX1 (human) gene expression decreases after overload, but the time course of Six1 expression, if protein is affected, and if the response differs between muscles with differing phenotypes, is not known. Our purpose was to examine Six1 gene and protein expression and co-factor gene expression during the initiation of muscle overload, and determine if the muscle phenotype altered this response.

Therapeutic ultrasound affects IGF-1 splice variant expression in human skeletal muscle.

Background: Animal models of skeletal muscle damage and repair demonstrate that therapeutic ultrasound (TUS) enhances muscle force recovery after damage, increases satellite cell proliferation, and decreases insulin-like growth factor (IGF)-1 splice variant (mechano growth factor) gene expression. However, these effects have not been verified in humans.

Purpose: This study was undertaken to examine the 3 known splice variants of the IGF-1 gene in human skeletal muscle after damage and TUS treatment.
