Background This systematic review was conducted with the first objective aimed at providing an overview of the physiological characteristics commonly evaluated in rugby and the corresponding tests used to measure each construct. Secondly, the measurement properties of all identified tests per physiological construct were evaluated with the ultimate purpose of identifying tests with strongest le...

One may ask if the transition to bipedalism from condition of quadrupedalism, which occurred about 7 million years ago, has been cause or consequence a series fundamental physiological muscular aspects including cost locomotion, crucial determinant endurance, found be significantly lower in humans than apes. This issue strictly links unsolved issues regarding significance several structural and...

BACKGROUND Naval Air Warfare Center Aircraft Division investigated the abilities of small-stature females (< or = 120 lb.) to fly under G-stress using the Dynamic Flight Simulator (DFS) and its tactical fight/attack cockpit, displays and controls. The objective was to determine if these individuals possess sufficient upper-body muscular endurance to perform tasks required during fighter-pilot t...

This study examined the effect of concurrent muscular strength and high-intensity running interval training on professional soccer players' explosive performances and aerobic endurance. Thirty-nine players participated in the study, where both the experimental group (EG, n = 20) and control group (CG, n = 19) participated in 8 weeks of regular soccer training, with the EG receiving additional m...

Duchenne muscular dystrophy (DMD), the most common form of muscular dystrophy, is characterized by muscular wasting caused by dystrophin deficiency that ultimately ends in force reduction and premature death. In addition to primary genetic defect, several mechanisms contribute to DMD pathogenesis. Recently, antioxidant supplementation was shown to be effective in the treatment of multiple disea...

Ratings of perceived exertion (RPE) are routinely assessed in exercise science and RPE is substantially associated with physiological criterion measures. According to the psychobiological model of endurance, RPE is a central limiting factor in performance. While RPE is known to be affected by psychological manipulations, it remains to be examined whether RPE can be self-regulated during static ...

BACKGROUND: Fitness could influence task performance in police officers. Limited research details relationships between different fitness characteristics and police-specific tasks. OBJECTIVE: Determine anaerobic aerobic capacity with performance. METHODS: Data for 308 recruits was analysed. tests included: push-ups, sit-ups, mountain climbers (muscular endurance); pull-ups (strength); vertical ...

Recently, Kon et al. (2014) published in this journal an interesting paper entitled “Effects of systemic hypoxia on human muscular adaptations to resistance exercise training “ which determined the effect of 8 weeks of resistance training (5 sets of 10 reps at 70% of 1 RM of free weight bench-press and bilateral leg-press using a weight-stack machine) under hypoxia (HRT, 14.4% O2) or normoxia, ...
