The daily doses per body weight of BCAA and taurine were 145.7 ± 5.3 (109.5–181.5) and 95.5 ± 2.5 (80.3–116.5) mg/kg (mean ± standard error, range), respectively. The placebo-1 and -2 supplements were compounded to the selleck inhibitor same volume and color as the BCAA and taurine supplements, respectively, by using similar proportions of starch for the double-blind

method (Table 1). Supplementation was continued in a double-blind manner until dinner on the third day after exercise. Evaluation using a visual analogue scale (VAS) and by assessing muscle damage markers was completed on the morning of the fourth day after exercise. No significant differences in physical parameters measured a week before starting supplementation were noted between the groups (Table 1). All subjects were sedentary

men who were non-athletes. They were instructed to continue their click here normal activities and to abstain from any strenuous exercise for at least one month before the experiment. Moreover, they were instructed to continue their usual food intake, not to change the amount or frequency of dietary meat or seafood intake, and not to use any dietary supplements, anti-inflammatory drugs, or anything else that could affect muscle soreness and damage until the end of the study. They were also instructed to abstain from stretching or massage therapy during the experimental period. Figure 1 A schematic illustrating the experimental protocol and time course of the present study. EPZ-6438 mouse Participants Lepirudin were supplied with two kinds of sachets consists of combination of BCAA (or placebo of BCAA) and taurine (or placebo of taurine) from 2 weeks before exercise to the end of the experiment. Participants were performed elbow extension as part of ECC in the non-dominant arm using dumbbell weight. Muscle soreness

and damage were then monitored for 4 days after ECC. Abbreviations: PRE, prior to amino acid supplementation; BEx, before exercise; AEx, immediately after exercise; Day1-Day4, 1st to 4th days following exercise; ECC, 6 sets of 5 repetitions of eccentric elbow extensions at 90% of maximal isometric strength; VAS, visual analogue scale for delayed onset muscle soreness assessment; CIR, upper arm circumference; Blood, blood sampling; Amino Acids, combination of amino acids (BCAA and/or taurine) supplementation; Suppl., supplementation; B, breakfast; L, lunch; D, dinner. Exercise protocol Figure 1 outlines the experimental protocol, including the time course corresponding to amino acid supplementation, exercise, and parameter measurement. On the day of exercise, all subjects assembled at our laboratory at 07:00 after fasting overnight. Following blood sampling, they ingested their assigned supplements 15 min prior to performing ECC. After the exercise at 10:00, subjects were supplied with jelly-type food (160 kcal/180 g; Nihon Pharmaceutical Co., Ltd.
