The aim of this study was to examine the association of perceived respiratory and muscular exertions and associated training load (TL) for monitoring changes in several aerobic fitness and neuromuscular performance parameters during 32 weeks of soccer training in young professional players. Twenty male soccer players (age=20.6±1.8 years, body height=1.80±.06 m, body mass=73.6±6.7 kg) belonging ...

BACKGROUND In Spain, more than 50% of 60-year-olds are obese. Obesity is a disease with serious cardiovascular risks. The mortality rate for cardiovascular disease in Spain is 31.1%. OBJECTIVES To improve aerobic fitness, strength, flexibility and balance, and body composition (BC) in persons over 60 years old. MATERIALS AND METHODS A clinical intervention study of 24 participants was carri...

To identify individual response patterns in selected aerobic fitness variables of regular starters (ST; N = 7) and non-starters (Non-ST; N = 10), top level professional soccer players were tested for maximal oxygen uptake (VO2max), velocity at 4 mM of lactate (V4), velocity at maximal oxygen uptake (νVO2max) and oxygen pulse (O2-pulse) in July and December following consecutive periods of fixtu...

The aim of this study was to address the question if the VO2 kinetics is further improved as the aerobic training status increases from trained to elite level athletes. Maximal oxygen uptake (VO2max), work-rate associated to VO2max (IVO2max) and VO2 kinetics of moderate (Mod) and maximal exercise (Max) were determined in fifty- five subjects. Then, they were assigned into three groups: low (LF)...

OBJECTIVE We sought to examine whether change in physical activity energy expenditure (PAEE) is associated with change in metabolic risk factors and whether this association is independent of change in fat mass and aerobic fitness. RESEARCH DESIGN AND METHODS In a population-based sample of 176 men and 217 women followed prospectively for 5.6 years, we measured PAEE by individually calibrated...

BACKGROUND Stress fractures account for substantial morbidity for young women undergoing U.S. Marine Corps basic training. HYPOTHESIS Certain pretraining characteristics identify women at increased risk of stress fractures during boot camp. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS Data collected included baseline performance on a timed run (a measure of aerobic fitness), a...

OBJECTIVES To examine the relations between maximal and submaximal indices of aerobic fitness and off road cycling performance in a homogeneous group of high level mountain bikers. METHODS 12 internationally competitive mountain bikers completed the study. Maximum oxygen uptake (Vo(2max)), peak power output (PPO), power output (PO), and oxygen uptake (Vo(2)) at first (VT) and second (RCT) ven...
