The flavanol (-)-epicatechin, a component of cacao (cocoa), has been shown to have multiple health benefits in humans. Using 1-year-old male mice, we examined the effects 15 days (-)-epicatechin treatment and regular exercise on: (1) performance, (2) muscle fatigue, (3) capillarity, (4) mitochondrial biogenesis mouse hindlimb heart muscles. Twenty-five mice (C57BL/6N) were randomized into four groups: water, water-exercise (W-Ex), ((-)-Epi), (-)-epicatechin-exercise ((-)-Epi-Ex). Animals...
The purpose of this study was to examine the acute effects a caffeine-containing supplement on upper- and lower-body strength muscular endurance as well anaerobic capabilities. Thirty-seven resistance-trained men (mean +/- SD, age: 21 2 years) volunteered participate in study. On first laboratory visit, subjects performed Wingate Anaerobic Tests (WAnTs) determine peak power (PP) mean (MP), tests for 1 repetition maximum (1RM), dynamic constant external resistance strength, (TOTV; total...
Thrombospondin‐1 (TSP‐1) is a known inhibitor of angiogenesis; however, skeletal muscle phenotype TSP‐1 null mice has not been investigated. The purposes this study were to compare and contrast wild‐type by examining the following: (1) capillarity in cardiac muscles; (2) fibre type composition oxidative enzyme activity hindlimb; (3) consequences gene deletion for exercise capacity. In mice, maximal running speed was 11% greater time exhaustion during submaximal endurance 67% compared with...
The purpose of this study was to examine the patterns for mechanomyographic (MMG) and electromyographic (EMG) amplitude mean power frequency (MPF) vs. torque relationships during submaximal maximal isometric isokinetic muscle actions. Seven men (mean +/- SD age, 22.4 1.3 years) volunteered perform concentric leg extension actions at 20, 40, 60, 80, 100% voluntary contraction (MVC) peak (PT) on a Cybex II dynamometer. A piezoelectric MMG recording sensor placed between bipolar surface EMG...
The purpose of this study was to determine the effects resistance training in combination with a leucine and whey protein supplement or carbohydrate placebo on strength muscle cross-sectional area (CSA). Thirty-three men (mean age +/- SD = 22.4 2.4 years) were assigned 1 3 groups: (1) supplementation group (SUPP), (2) (PL), (3) control (CON). SUPP PL performed unilateral leg extensor muscles nondominant limb for 8 weeks. each limb, CSA quadriceps femoris (QF), body composition assessed...
Beck, TW, Housh, TJ, Malek, MH, Mielke, M, and Hendrix, R. The acute effects of a caffeine-containing supplement on bench press strength time to running exhaustion. J Strength Cond Res 22(5): 1654-1658, 2008-The purpose the present study was examine (SUPP) one-repetition maximum (1-RM) exhaustion (TRE) at velocity that corresponded 85% peak oxygen uptake (O2peak). used double-blinded, placebo-controlled, crossover design. Thirty-one men (mean ± SD age = 23.0 2.6 years) were randomly assigned...
The purpose of this secondary analysis was to report the psychometric properties Patient-Reported Out comes Measurement Information Systems (PROMIS) Computer Adaptive Test (CAT) - Fatigue in individuals receiving hemodialysis (HD) treatment. Measures included Piper Scale-12, Six-Minute Walk Test, PROMIS CAT-Fatigue, and Charlson Comorbidity Index. English-speaking adults older than 18 years, cognitively intact, two three times weekly HD treatment were included. A total 86 (M = 61.7 SD...
The purpose of this investigation was to examine the effects 3 days velocity-specific isokinetic training on peak torque (PT) and electromyographic (EMG) signal. Thirty adult women were randomly assigned a slow-velocity (SVT), fast-velocity (FVT), or control (CON) group. All subjects performed maximal, concentric, leg extension muscle actions at 30 270 degrees .s(-1) for determination PT visits 1 (pretest) 5 (posttest). Electromyographic signals recorded from vastus lateralis, rectus...
