The aim of this study was to determine the influence of activity performed during the recovery period on the aerobic and anaerobic energy yield, as well as on performance, during high-intensity intermittent exercise (HIT). Ten physical education students participated in the study. First they underwent an incremental exercise test to assess their maximal(More)
BACKGROUND Excessive time in front of a single or several screens could explain a displacement of physical activity. The present study aimed at determining whether screen-time is associated with a reduced level of moderate to vigorous physical activity (MVPA) in Spanish adolescents living in favorable environmental conditions.

To assess if exercise before puberty affects bone mineral content (BMC) and bone mineral density (BMD) we determined BMC and BMD in the dominant arm (DA) and non-dominant arm (NDA), lumbar spine and femoral neck in 25 tennis players (TP), 21 soccer players (SP) and 22 physically active controls (CG). All of them were under 12 years of age and prepubertal.(More)
The effects of professional tennis participation on dominant and non-dominant upper extremity muscle volumes, and on fiber types of triceps brachii (lateral head) and vastus lateralis muscles were assessed in 15 professional tennis players. Magnetic resonance imaging (MRI, n=8) examination and dual-energy x-ray absorptiometry (DXA, n=7) were used to assess(More)
OBJECTIVE To determine whether long-term recreational tennis participation is associated with increased bone and muscle mass in the dominant compared to the non-dominant arm, in postmenopausal tennis players. METHODS Dual-energy X-ray whole body scans were performed in 10 postmenopausal tennis players (mean +/- S.D.; 59.7 +/- 4.8 years) and 12(More)
Professional tennis players (TP) have marked inter-arm asymmetry in bone mass (BMC) and density (BMD). To determine if this asymmetry is influenced by training frequency and volume, we studied 24 young tennis players (mean age 10.6 years, Tanner 1–2), 17 physically active control boys (CG) and ten male professional tennis players. Young TP were divided into(More)
PURPOSE To determine the volume and degree of asymmetry of the musculus rectus abdominis (RA) in professional tennis players. METHODS The volume of the RA was determined using magnetic resonance imaging (MRI) in 8 professional male tennis players and 6 non-active male control subjects. RESULTS Tennis players had 58% greater RA volume than controls (P =(More)
We compared the effects of two resistance training (RT) programs only differing in the repetition velocity loss allowed in each set: 20% (VL20) vs 40% (VL40) on muscle structural and functional adaptations. Twenty-two young males were randomly assigned to a VL20 (n = 12) or VL40 (n = 10) group. Subjects followed an 8-week velocity-based RT program using the(More)
BACKGROUND To determine whether androgen receptor (AR) CAG (polyglutamine) and GGN (polyglycine) polymorphisms influence bone mineral density (BMD), osteocalcin and free serum testosterone concentration in young men. METHODOLOGY/PRINCIPAL FINDINGS Whole body, lumbar spine and femoral bone mineral content (BMC) and BMD, Dual X-ray Absorptiometry (DXA), AR(More)
PURPOSE To determine the volume and degree of asymmetry of the rectus abdominis muscle (RA) in professional soccer players. METHODS The volume of the RA was determined using magnetic resonance imaging (MRI) in 15 professional male soccer players and 6 non-active male control subjects. RESULTS Soccer players had 26% greater RA volume than controls(More)
