Branched-chain amino acids (BCAA) supplementation has been considered an interesting nutritional strategy to improve skeletal muscle protein turnover in several conditions. In this context, there is evidence that resistance exercise (RE)-derived biochemical markers of muscle soreness (creatine kinase (CK), aldolase, myoglobin), soreness, and functional strength may be modulated by BCAA suppleme...

A free radical-scavenging preparation (pollen extract) or the corresponding placebo was given to 50 volunteers over a period of 4 weeks to test the hypothesis that muscle soreness is associated with the generation of free radicals. The increase in malonyldialdehyde and lactate immediately after exercise both in blood and in muscle tissue was significantly lower after treatment with the scavengi...

QUESTION Does warm-up or cool-down (also called warm-down) reduce delayed-onset muscle soreness? DESIGN Randomised controlled trial of factorial design with concealed allocation and intention-to-treat analysis. PARTICIPANTS Fifty-two healthy adults (23 men and 29 women aged 17 to 40 years). INTERVENTION Four equally-sized groups received either warm-up and cool-down, warm-up only, cool-do...

BACKGROUND Post-exercise muscle soreness is a dull, aching sensation that follows unaccustomed muscular exertion. Primarily on the basis of previous laboratory-based research on eccentric exercise, soreness is usually said to follow an inverted U-shaped curve over time, peaking 24 - 48 hours after exercise. As such, it is often described as "delayed-onset" muscle soreness. In a study of long-di...

Looking to keep the soreness at bay, eh? Muscle soreness, characterized by pain, tenderness, stiffness, swelling in the muscles, often happens to people who are just beginning to pump iron [2] ? but it can also be experienced by seasoned weight training enthusiasts. What?s more, having sore muscles isn?t only physically uncomfortable, it?s also associated with reduced muscle strength and range ...

This study investigated the effect of a supplement containing 9 essential and 3 non-essential amino acids on muscle soreness and damage by comparing two endurance exercise bouts of the elbow flexors with amino acid or placebo supplementation in a double blind crossover design. The supplement was ingested 30 min before (10 h post-fasting) and immediately after exercise (Experiment 1), or 30 min ...

OBJECTIVE To pilot a model for determining whether a homoeopathic medicine is superior to placebo for delayed onset muscle soreness (DOMS). DESIGN Randomised double blind placebo controlled trial. SETTING Physiotherapy department of a homoeopathic hospital. SUBJECTS Sixty eight healthy volunteers (average age 30; 41% men) undertook a 10 minute period of bench stepping carrying a small wei...

objective(s): the purpose of the present study was to examine the effects of l-glutamine on electromyographic (emg) activity of the quadriceps muscle injured by eccentric exercise (ee).   materials and methods: seventeen healthy men (age: 22.35±2.27 yr; body mass: 69.91±9.78 kg; height: 177.08±4.32 cm) were randomly and double-blind study with subjects assigned to either an l-glutamine suppleme...

[Purpose] The aim of this study was to investigate whether or not a single whole-body vibration treatment after eccentric exercise can reduce muscle soreness and enhance muscle recovery. [Subjects and Methods] Twenty untrained participants were randomly assigned to two groups: a vibration group (n=10) and control group (n=10). Participants performed eccentric quadriceps training of 4 sets of 5 ...
