- The influence of sport practices on body composition, maturation and maximum oxygen uptake in children and youthPublication . Mercê, Cristiana; Branco, Marco A. C.; Rodrigues Ferreira, Mário André; VencesBrito, Antonio; Catela, David; Seabra, Ana Paula; Milheiro, Vítor; Cynarski, WojciechSystematic sport practice at younger ages positively influences body composition and maximum oxygen uptake (VO2max). On the other hand, its influence on maturation is still not consensual, and some studies claim a negative effect. Few studies have approached the differences in this influence according to different sport practices. The present study aims to analyse and compare the influence of karate and swimming practices, and the non-practice of sports, on body composition, VO2max and maturation in children and youth. Data were collected in 126 youth, 54 karate athletes, 36 swimming athletes and 36 participants with no sport practice (M=11.56±2.06 years). The type of sport practice had a different influence on body composition and VO2max, no negative influence was verified on maturation. In general, the sport practices revealed a positive influence in children and youth’s body composition. The karate practice provided significant lower body fat mass and higher lean mass in males. Swimming athletes revealed a significant higher VO2max compared to all other groups, while karate didn´t differed from no-practice group. The different influence of sport practices verified highlighted the importance of a multilateral development of children and youth by practising several sports.
- Nicknames reciprocally attributed among portuguese surfers and bodyboarders as body techniques’ metaphorsPublication . Catela, David; Milheiro, Vítor; Frazão, Henrique Manuel Pereira de OliveiraBody techniques require the embodiment of pre-reflective principles and are constrained by the physical and functional properties of the instrument used. Nicknames miniaturize particular characteristics because it is an intentional way of representing a distinct dentity and of adding humor. Surfers and bodyboarders share same natural space, with different instruments and body techniques. The purpose of this was to detect if reciprocal nicknames attributions reflect cultural differences, based on respective identitary body techniques. Materials and Methods: Non-experimental descriptive study, with a convenient sample of 31 surfers, 10 bodyboarders, and 8 surfers and bodyboarders, aged between 13 and 38 years old, with a practice experience between 1 and 25 years, with a structured survey with opened questions. Results: Results sustain the hypothesis that nicknames are systematic and follow a pattern, being humouristically formed and reformed relative to the topology of the bodyboarders’ body techniques and of the surfers’ instrument. Conclusion: Reciprocal nicknames attributed among Portuguese surfers and bodyboarders seem to crystalize interrelated semiotic processes instruments, actions, and identities) of the residential whole of these surfing cultures, through masked protective and social terms, expressing a context of coexistence and playfulness, predominantly based on body techniques topology.
