guest blog by: Michael J. Ormsbee, Lillie Renteria, and Casey Greenwalt.Most people believe eating before sleep makes you accumulate fat because you are resting for multiple hours after you eat....

Caffeine is both a drug and a nutrient. A cup of coffee in the morning is used to wake up a cup in the evening is often used to work or study late. Athletes often use it to improve endurance perfor...

This study explored the influence of habitual caffeine intake on the acute effects of caffeine ingestion on resistance exercise, jumping, and Wingate performance. Resistance-trained males were test...

CrossTalk proposal: Exercise training intensity is more important than volume to promote increases in human skeletal muscle mitochondrial content

Purpose: Preconditioning exercise is a widely used strategy believed to enhance performance later the same day. The authors examined the influence of preconditioning exercises 6 hours prior to a...

and short recovery time (15–30 s) might suit individuals with limited time to exercise. Purpose We examined the effects of training at near maximal anaerobic power during cycling (PC) on maximal...

Hypohydration, or a body water deficit, is a common occurrence in athletes and recreational exercisers following the completion of an exercise session. For those who will undertake a further exercise...

Purpose: The primary objective was to assess the performance benefits of caffeine (CAF) supplementation in habitual users. Importantly, this investigation was designed to account for the potential...

Iron plays an important role in several exercise-relevant processes such as red blood cell production, and energy metabolism, whilst also contributing to our cognitive function, and the body’s immune...

Repeated days of hard training typically result in an accumulation of fatigue. How can the diet influence this?

Purpose: To investigate the placebo effect of caffeine on pacing strategy and performance over 1000-m running time trials using a balanced placebo design. Methods: Eleven well-trained male middle-d...

ate type, amount, and timing of intake of food, fluids, and supplements to promote optimal health and performance across different scenarios of training and competitive sport. This position paper was...

The aim of this study was to compare the effectiveness of exercise versus hot water immersion heat reacclimation (HRA) protocols.Twenty-four participants completed a heat stress test (HST; 33°C, 65%...

Sports Medicine - Heat acclimation and acclimatisation (HA) is typically used to enhance tolerance to the heat, thereby improving performance. HA might also confer a positive adaptation to maximal...

The Journal of Physiology publishes research in all areas of physiology and pathophysiology that illustrates new physiological principles or mechanisms.

このたび，本学で最初の「ツクバ・トップ・ランナー教員」として，2名の教員に対して教員抜擢昇任人事制度を適用したことをお知らせします。この2名の「ツクバ・トップ・ランナー教員」が，2018年10月から5年の期間中に卓越した研究力を発揮して極め

Lactose is a sugar found in milk. Is this type of carbohydrate a good source ion energy during exercise? This blog looks at the results of a recent study tat compared lactose with sucrose. What is...

group (CON-1). Furthermore, after the 5-wk intervention, we tested whether three sessions per week for 3 wk with heat suit (SUITmain) would maintain Hbmass elevated compared with athletes who...

Sports Medicine - Heat is associated with physiological strain and endurance performance (EP) impairments. Studies have investigated the impact of caffeine intake upon EP and core temperature (CT)...

European Journal of Applied Physiology - We evaluated (1) whether participating in middle- and long-distance running races augments muscle soreness, oxygen cost, respiration, and exercise exertion...

Sports Medicine - Physiological heat adaptations can be induced following various protocols that use either artificially controlled (i.e. acclimation) or naturally occurring (i.e. acclimatisation)...

Purpose: We investigated whether varying the number of repetitions of high-intensity exercise during work-matched warm-ups modulates physiological responses (heart rate, metabolic responses, and co...

Ingestion of dietary nitrate is associated with improved exercise tolerance and reduced oxygen (O2) cost of exercise, ascribed to enhanced mitochondrial efficiency, muscle contractile function, or...

Sports Medicine - Heat adaptation regimes are used to prepare athletes for exercise in hot conditions to limit a decrement in exercise performance. However, the heat adaptation literature mostly...

It is a well established fact that the body temperature increases during muscular exercise, and that the increase is regulated (NIELSEN, 1938). It was the purpose of this paper to study the effect...

dium alginate and pectin (hydrogel) on endurance running performance, exogenous and endogenous CHO oxidation, and GI symptoms. Methods Eleven trained male runners, using a randomized, double-blind...

Sports Medicine - The ergogenic effects of dietary supplements on endurance exercise performance are well-established; however, their efficacy in hot environmental conditions has not been...
