Most running studies have considered level running (LR), yet the regulation of locomotor behaviour during uphill (UR) and downhill (DR) running is fundamental to increase our understanding of human locomotion.

THE purpose of this study was to determine which strength training exercises selectively activate the biceps femoris long head (BFLongHead) muscle.

The aim of this study was to analyze physical performance and physiological variables during High-Intensity Resistance Circuit Training (HRC) with the addition of two levels (moderate and high) of systemic hypoxia.

Our current state of knowledge regarding the load (lighter or heavier) lifted in resistance training programmes that will result in ‘optimal’ strength and hypertrophic adaptations is unclear.

Low-volume high-intensity interval training holds promise for cardiometabolic health promotion in adolescents, but sustainable interventions must be practical and engaging.

Eleven elite judoka (age: 14.8 ± 0.6 years, height: 163.2 ± 7.5 cm, body mass: 57.3 ± 11.1 kg, 5 boys/6 girls, and strength training experience: 2.7 ± 1.1 years) performed two 4-week strength training mesocycles (each with 12 sessions) with either traditional (TP) or daily undulating (DUP) periodization.

Hyperoxia results from the inhalation of mixtures of gas containing higher partial pressures of oxygen (O2) than normal air at sea level.

Over the last two decades, exercise of the core muscles has gained major interest in professional sports.

Research on the health of female athletes has developed substantially over the past 50 years.

Muscle strength is often measured through the performance of a one-repetition maximum (1RM).

The aim of this study was to investigate lactate recovery kinetics after high-intensity exercises.

Sprint interval training (SIT) provides a potent stimulus for improving maximal aerobic capacity ([Formula: see text]), which is among the strongest markers for future cardiovascular health and premature mortality.

The use of energy drinks among athletes has risen greatly.

Subacromial impingement syndrome (SIS) has been reported as an etiological source of shoulder pain among weight-training (WT) participants; however, a paucity of evidence exists to describe intrinsic risk factors.

For over three decades, muscle biologists have been fascinated by reactive oxygen species (ROS) generated in exercising muscle and the potential role that ROS may play in fatigue.

In strength training (ST), muscle activity is often analyzed by surface electromyography (EMG) and muscle damage through indirect markers, such as plasma concentrations of creatine kinase (CK) after exercise. However, there is little information about the influence of the strength exercises order on these parameters.

The present study aimed to investigate the influence of subjects’ strength level on both the ability to maintain power output performance and the physiological and perceived exertion responses during a power training session when different rest intervals (RI) are used.

The purpose of this study was to investigate the effects of a caffeine-polyphenolic supplement on (a) metabolic rate and fat oxidation at rest and after a bout of sprint interval exercise (SIE) and (b) SIE performance.

Program variables such as training intensity, volume, and rest interval length are known to elicit distinct hormonal, metabolic, and physical responses.

Weight-training sports, including weightlifting, powerlifting, bodybuilding, strongman, Highland Games, and CrossFit, are weight-training sports that have separate divisions for males and females of a variety of ages, competitive standards, and bodyweight classes.

Muscle dysmorphia (MD) is associated with a self-perceived lack of size and muscularity, and is characterized by a preoccupation with and pursuit of a hyper-mesomorphic body.

Assessment of “exercise readiness” is a central component to the flexible non-linear periodization (FNLP) method of organizing training workloads, but the underlying factor structure of this construct has not been empirically determined.

Cortisol (C) and testosterone (T) are impacted significantly by prolonged endurance exercise with inverse responses.

During the stages of long-term athlete development (LTAD), resistance training (RT) is an important means for (i) stimulating athletic development, (ii) tolerating the demands of long-term training and competition, and (iii) inducing long-term health promoting effects that are robust over time and track into adulthood.

The overarching aim of this study was to compare volume-equated high-repetition daily undulating periodization (DUPHR) versus a low-repetition daily undulating periodization (DUPLR) program for muscle performance.
