Human fast-twitch muscle fibers generate high power in a short amount of time but are easily fatigued, whereas slow-twitch more fatigue resistant. The transfer this knowledge to coaching is hampered by the invasive nature current evaluation typology biopsies. Therefore, noninvasive method was developed estimate through proton magnetic resonance spectroscopy gastrocnemius. aim study investigate whether male subjects with an priori-determined fast (FT) characterized pronounced Wingate...
Carnosine occurs in high concentrations human skeletal muscle and assists working capacity during high-intensity exercise. Chronic beta-alanine (BA) supplementation has consistently been shown to augment carnosine concentration, but the effect of training on loading efficiency is poorly understood. The aim present study was compare between trained untrained arm leg muscles. In a first (n = 17), reliability quantification by proton magnetic resonance spectroscopy ((1)H-MRS) evaluated deltoid...
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 relationship between urinary excretion and loading present, 2) the latter stimulated carbohydrate- protein-induced insulin action.In study A, effect of 5-wk slow-release BA (SRBA) supplementation (4.8 g · d(-1)) on whole body retention was determined in seven men. further whether coingestion carbohydrates proteins...
Abstract Balanced vegetarian diets are popular, although they nearly absent in creatine and carnosine contain considerably less carnitine than non-vegetarian diets. Few longitudinal intervention studies investigating the effect of a diet on availability these compounds currently exist. We aimed to investigate transiently switching omnivores onto for 6 months muscle plasma creatine, homeostasis. In 6-month intervention, forty omnivorous women were ascribed three groups: continued (control, n...
Introduction Chronic β-alanine (BA) supplementation is an increasingly popular nutritional strategy, because it can elevate muscle carnosine content and thereby enhance high-intensity exercise performance. The current study investigated 1) whether sex body mass are determinants of BA-induced loading 2) the optimal maintenance dose for ensuring constantly elevated stores. Methods During phase, 34 participants (men women) were supplemented with 3.2 g (4 × 800 mg) BA per day 46 d (slightly...
Muscle carnosine loading through chronic oral beta-alanine supplementation has been shown to be effective for short-duration, high-intensity exercise. This randomized, placebo-controlled study explored whether the ergogenic effect of is also present longer duration Subjects (27 well-trained cyclists/triathletes) were supplemented with either or placebo (6.4 g/day) 6 weeks. Time completion and physiological variables a 1-hr cycling time-trial compared between preand postsupplementation....
There is a continuing research interest in the muscle fiber type composition ( MFTC ) of athletes. Recently, carnosine quantification by proton magnetic resonance spectroscopy 1 H‐ MRS was developed as new non‐invasive method to estimate . This cross‐sectional study aims better understand estimated relation (a) different disciplines within one sport; (b) cyclic sport exercise characteristics; (c) within‐athlete variability; and (d) athlete level. A total 111 elite athletes (74 runners, 7...
Classic track-and-field studies demonstrated that elite endurance athletes exhibit a slow muscle typology, whereas sprint have predominant fast typology. In cycling, conclusive data on typology are scarce, which may be due to the invasive nature of biopsies. The noninvasive estimation through measurement carnosine enabled explore 80 world-class cyclists different disciplines.The content (4 bicycle motor cross racing [BMX], 33 track, 8 cyclo-cross, 24 road, and 11 mountain bike) was measured...
Beta-alanine (BA) supplementation has been shown to augment muscle carnosine concentration, thereby promoting high-intensity (HI) exercise performance. Trained muscles of athletes have a higher increase in concentration after BA compared untrained muscles, but it remains be determined whether this is due an accumulation acute effects or chronic adaptations from prior training. The aim the present study was investigate high-volume (HV) and/or HI can improve BA-induced loading subjects.All...
Excellence in either sprinting or endurance running requires specific musculo-skeletal characteristics of the legs. This study aims to investigate morphology leg sprinters and runners Caucasian ethnicity. Eight male 11 volunteered participate this cross-sectional study. They underwent magnetic resonance imaging after data collection, digital reconstruction was done calculate muscle volumes bone lengths. Sprinters have a higher total upper volume compared (7340 vs 6265 cm3 ). Specifically,...
Current results reveal that carnosine and anserine competitively bind to the highly active carnosinase enzyme in human plasma. Acute combined supplementation is therefore described as novel strategy raise plasma carnosine. We report indices of maximal exercise/muscle power during initial stage a Wingate test were significantly improved by preexercise 20–25mg/kg body wt supplementation, pointing toward acute nutritional improve high-intensity exercise performance.
