Eccentric exercise induces muscle damage and inflammation, resulting in a state of reduced physical activity with dysfunction feeling tiredness after exercise. Creatine is known to act as an energy buffer, but it has also been suggested exert inhibitory effects on peripheral inflammation. The purpose this study was test the hypothesis that creatine supplementation alleviates fatigue eccentric explore mechanism effect. C57BL/6J mice were fed AIN-93G-formulated control diet or...

Ice slurry ingestion enhances exercise performance by lowering the core body temperature. However, an operational issue related to this is requirement for a high intake of 7.5 g·kg -1 produce desired effects. We investigated effects low amounts ice at −2°C on tympanic temperature and during repeated high-intensity intermittent exercises in hot environment. This study was randomized, crossover study, with 6-day washout period. Twelve university rugby union players performed two 30-min...

The aim of this study was to investigate the effect ingestion ice slurry before bedtime on sleep quality rugby union players in summer season. Thirteen healthy male university volunteered for study. participants ingested either or a room-temperature beverage (control) 30 min bedtime. A wearable activity-based monitor used analyze objective parameters, and subjective scores were assessed using Oguri–Shirakawa–Azumi Sleep Inventory, middle-aged aged version (OSA-MA). No differences amount...

Delayed recovery of the core body temperature after exercise adversely affects physiological functions, and effects ingesting lower-temperature ice slurry on post-exercise remain unclear. We investigated −2 °C field-based rugby union training. Fifteen university players participated in our randomized controlled study. The training for 60 min a hot outdoor environment (wet-bulb globe temperature, 30.5 °C). Physiological responses were measured during physical performance test performed...
