Is the whole not greater than the sum of its parts? The case of sarcopenic obesity
muscle institutionalization fat mass sarcopenia
2018/11/14
Sarcopenia is defined as the loss of muscle mass and function with aging, which accelerates after the seventh decade of life and is a harbinger for the onset of disability and institutionalization (1)...
Postexercise repletion of muscle energy stores with fructose or glucose in mixed meals
athletes intramyocellular lipids muscle glycogen recovery,
2018/11/13
Background: Postexercise nutrition is paramount to the restoration of muscle energy stores by providing carbohydrate and fat as precursors of glycogen and intramyocellular lipid (IMCL) synthesis. Comp...
Relationships Between Lower-Body Muscle Structure and, Lower-Body Strength, Explosiveness and Eccentric Leg Stiffness in Adolescent Athletes
Muscle architecture children associations ultrasound
2016/2/23
The purpose of the present study was to determine whether any relationships were present between lower-body muscle structure and, lower-body strength, variables measured during a countermovement jump ...
Leukocyte telomere length is related to appendicular lean mass: cross-sectional data from the Berlin Aging Study II (BASE-II)
appendicular lean mass BASE-II leukocytes muscle mass sarcopenia telomere length
2018/11/23
Background: Age-related progressive loss of muscle mass is an increasing problem in our aging society, affecting physical ability, risk of falls, and need for health care. Telomere length has been rec...
β-alanine supplementation improves isometric endurance of the knee extensor muscles
β-alanine Carnosine Isometric endurance
2015/7/23
=We examined the effect of four weeks of β-alanine supplementation on isometric endurance of the
knee extensors at 45% maximal voluntary isometric contraction (MVIC).
Effects of acute creatine supplementation on iron homeostasis and uric acid-based antioxidant capacity of plasma after wingate test
Creatine Iron homeostasis Antioxidant
2015/7/23
Dietary creatine has been largely used as an ergogenic aid to improve strength and athletic
performance, especially in short-term and high energy-demanding anaerobic exercise. Recent findings have al...
Dose response effects of a caffeine-containing energy drink on muscle performance: a repeated measures design
Caffeine Sports nutrition Force productio
2015/7/23
Energy drinks have become the most used caffeine-containing beverages in the sport setting. The
aim of this study was to determine the effects of two doses of a caffeine-containing energy drink on mu...
Exercise-induced muscle damage is reduced in resistance-trained males by branched chain amino acids: a randomized, double-blind, placebo controlled study
Recovery, BCAA Muscle damage Resistance training
2015/7/23
It is well documented that exercise-induced muscle damage (EIMD) decreases muscle function and
causes soreness and discomfort. Branched-chain amino acid (BCAA) supplementation has been shown to incre...
Effects of carbohydrates-BCAAs-caffeine ingestion on performance and neuromuscular function during a 2-h treadmill run: a randomized, doubleblind, cross-over placebo-controlled study
erformance and neuromuscular randomized
2015/7/22
Carbohydrates (CHOs), branched-chain amino acids (BCAAs) and caffeine are known to improve
running performance. However, no information is available on the effects of a combination of these ingredien...
The effect of beta-alanine supplementation on neuromuscular fatigue in elderly (55–92 Years): a double-blind randomized study
neuromuscular fatigue beta-alanine
2015/7/14
Ageing is associated with a significant reduction in skeletal muscle carnosine which
has been linked with a reduction in the buffering capacity of muscle and in theory, may increase the
rate of fati...
Meal and Beta-Alanine Coingestion Enhances Muscle Carnosine Loading
BETA-ALANINE RETENTION, ERGOGENIC SUPPLEMENTS, CARNOSINE SYNTHASE, BETA-ALANINE METABOLIZATION
2017/7/17
Introduction: Beta-alanine (BA) is a popular ergogenic supplement because it can induce muscle carnosine loading. We hypothesize that, by analogy with creatine supplementation, 1) an inverse relations...
