Leg muscle mass and strength are decreased during reduced activity and non-weight-bearing conditions such as bed rest (BR) and spaceflight. Supine treadmill exercise within lower body negative pressure (LBNPEX) provides full-body weight loading during BR and may prevent muscle deconditioning. We hypothesized that a 40-min interval exercise protocol performed against LBNPEX 6 days week(-1) would...

Physical fitness assessments for tactical occupations (e.g., military, law enforcement, and emergency services) can include predictive tests of anaerobic power, cardiovascular fitness, muscular endurance, strength, agility, and/or simulated occupational tasks. Not only these be used to assess the ability someone undertake job role but they determine injury risk, training failure, general health...

Forty-five men (18-35 years) trained three times a week for eight weeks to determine the effects of four constant-resistant weight training programmes on muscular strength, endurance, body composition and cardiovascular functioning. Subjects were randomly assigned to one of four programmes: Endurance (2 sets of 15 repetition maximum [RM]); Explosive (1 set of 15 RM); Strength 1 (3 sets of 6 RM)...

Changes in muscle mass and strength across the adult age span are variable and related to the ciliary neurotrophic factor (CNTF) genotype. In particular, a single CNTF haplotype (1357 G→A) is important for neuronal and muscular developments and may be associated with muscle strength response to resistance training. We examined whether CNTF genotype differentially influences the effect of resist...

BACKGROUND Back pain is a common condition during childhood and adolescence. The causes of back pain are largely unknown but it seems plausible that some physical factors such as back muscle strength, back muscle endurance and aerobic capacity may play a role in its development, in particular in the early years. OBJECTIVES The objectives of this review were to investigate in childhood and ado...

The study examined the relationship between selected motor tests and competitive successfulness in tennis for different age categories. The sample was comprised of 615 tennis players of both genders in the age categories of under-14 and under-18 years. Several motor abilities were investigated: the neuromuscular power of the arms, the elastic power of the legs, the dynamic muscular strength end...

This review aimed to analyze the impact of whole-body-vibration (WBV) training on strength, power, muscle endurance, functional lower-extremity flexibility (FLEF), and strength (FLES) in older adults evaluate effectiveness different WBV periods. Electronic searches were conducted using four databases. The methodological quality level evidence selected articles assessed by two reviewers. Standar...

Do you constantly battle muscle cramps during intense or long training? Does muscular weakness prevent you from putting forth full effort? Do asthmatic symptoms prevent you from completing workouts? Does it feel as if your heart skips a beat, causing feelings of lightheadedness and dizziness? Are physical returns from an intensive strength training program less than anticipated? If you answered...

The professionalization of the army is one main components process creating optimal numbers, mobile, well-armed, combat-capable Armed Forces in Ukraine. At current stage, combat capability Ukraine ensured not only by availability latest types weapons, sufficient funding training activities and full staffing, but also high level military professional servicemen, quality dynamism educational inst...
