Physical Growth and Changes in Intermittent Endurance Run Performance in Young Male Basque Soccer Players

Abstract

The present 4-year longitudinal study examined physical growth and development of intermittent endurance run performance in young Basque soccer players aged 10-15 years applying multilevel regression modeling. Anthropometry, predicted adult stature and Yo-Yo Intermittent Recovery level 1 test (Yo-Yo IR1) of players from the under-11 teams from the Athletic Club of Bilbao were measured at pre- and end-season (two measurements per year of study, n = 33 considered for analysis). A non-linear effect of age on intermittent endurance run was observed, with significantly higher increases in Yo-Yo IR1 between 10-11 year-old and 14-15 year-old players. The development of Yo-Yo IR1 performance in all the years of the study was influenced positively by training exposure during the seasons (P < 0.01) and independent of maturity status and body size (P > 0.05). The steady development of intermittent endurance run performance during pubertal years in adolescent Basque soccer players is partially influenced by training exposure.

Growth, functional capacities and motivation for achievement and competitiveness in youth basketball: an interdisciplinary approach

“…Variation by maturity status group in intermittent endurance performance was explained by chronological age per se. These observations concur with recent longitudinal data in adolescent soccer players (Carvalho et al, 2014;Deprez et al, 2014), but contrast with longitudinal observations of male adolescents in general (Beunen et al, 2002;Welsman & Armstrong, 2000), among whom maturity status influences maximal oxygen consumption only after adjusting for age and body dimensions. Additionally, the size exponents derived from the allometric scaling are consistent with observations in samples of adolescent basketball players and lower than those in studies of young athletes (Cunha et al, 2011;Eisenmann, Pivarnik, & Malina, 2001).…”

Understanding the Mismatch Between Coaches’ and Players’ Perceptions of Exertion

“…In addition, it is known that when players grow mature, intermittent endurance capacity also improves. 26,27 Thus, coaches might have included maturity status through accounting for ISRT in scoring intended and observed exertion.…”

Motor Performance in Male Youth Soccer Players: A Systematic Review of Longitudinal Studies

“…All studies were from the European continent: eight were conducted in Portugal (25.8%) [19,22,[25][26][27][28][29][30], seven in Belgium (22.6%) [17,23,[31][32][33][34][35], four in the United Kingdom (12.9%) [36][37][38][39], three in the Netherlands (9.7%) [18,40,41], three in Spain (9.7%) [24,42,43], two in Italy (6.5%) [20,44]. Single studies were conducted in Austria [45], Finland [46], Germany [47], Switzerland [21], and Serbia [48] (Figure 2).…”
