The analysis of endurance, speed and explosive strength in young football players
2011
Introduction Endurance, speed and explosive strength are determinant factors of sporting performance for football players (Hoff & Helgerud, 2004). An evaluation of these abilities is fundamental in young subjects, who have still not completed their maturation, to plan an individualised and effective training program (Fernandez-Gonzalo et al., 2010). The aim of this study was to examine the level of variability in endurance, speed and explosive strength of lower limbs among young football players. Methods Sixteen male players with 5 years of experience playing football and participating in the “Giovanissimi Regionali” amateur championship (14.00 years old ± 7 months; 57.5 ± 6.66 kg weight, 1…
Relationship between heart rate variability and repeated sprint exercise in young soccer players
2014
Aim: The sport of soccer is characterized by neuromuscular performance resulting in short bursts interspersed by brief recovery periods over an extended period of time. Several studies suggest that the cardiac autonomic nervous system (ANS) assessed by heart rate variability (HRV) may provide useful information regarding the functional adaptations to training stimulus. Although HRV has often been associated with aerobic power and cardiovascular fitness, the influence of sympathovagal balance on neuromuscular performance in young athletes is not well assessed. The aim of this study was to assess the influence of the autonomic system on the performance of repeated sprints, involving predomina…
Influences of baseline heart rate variability on repeated sprint performance in young soccer players
2015
AIM: The aim of this study was to assess the influence of the autonomic system on the performance of repeated sprints, involving predominantly neuromuscular power, in young soccer players. METHODS: Twelve young soccer players, selected for the Sicilian Regional Football Representative, mean age 15 years, were recruited. Baseline heart rate variability (HRV) was measured and indices of power spectral analysis (LF, HF, and ratio LF/HF) were calculated to evaluate the sympathovagal balance. The athletes performed 10 maximal 6--sec cycling sprints (RS), interspersed with 30--sec of recovery, to measure the peak power output (PP) represented by the highest power value recorded during a 6--sec sp…
