Power and speed among youth athletes from different tam sports
(Schnellkraft und Schnelligkeit bei Nachwuchssportlern verschiedener Mannschaftssportarten)
Team-sport training is generally characterized and by a diverse range of training types. Power and speed are variables that influence the performance of the athletes and are frequently tested to provide a profile as well as training-induced adaptations. Considering that the performance is specific to training and to the type of sport, the aim of this study was to evaluate the jump capacity (countermovement- jumps (CMJ), squat jumps (SJ) and CMJ with arms swing (CMJW)) and speed 20 meters sprint (20S)) of young athletes from different team-sports Basketball, Futsal, Handball and Volleyball during the preparation phase for the 2008 Youth Games of Parana State-Brazil.
Methods: The sample was composed of 45 male (Age: 16.3±0.6 years; Height: 1.81±0.4 m; Weight: 73.6±9.9 kg) and 41 female (Age: 15.5±1.1 years; Height: 1.66±0.4 m; Weight: 60.4±6.7 kg). The study was approved by the university human ethics committee and all subjects signed an informed consent document. The vertical jumps were collected according to Bosco protocol. The subjects stood on a contact mat and the jump height was calculated by an Ergojump apparatus (Bosco system). Three attempts were allowed and the highest one was recorded for each test. The speed was measured with a wireless time system composed of 3 pairs of infrared emitters at the 0-m, 10-m and the 20-m marks. Each subject completed two attempts and the fastest trial was recorded. The One way ANOVA was utilized to test the differences among the group of means and the Scheffee Pos Hoc was used as the follow-up test. The significance level was set at p ≤ 0.05.
Results: For the male athletes the results were: VERTICAL JUMP: Basketball (N 12)-SJ: 33.6±4.5 cm; CMJ: 37.5±4.0; CMJW: 45.0±5.1.Futsal (N 10)-SJ: 33.6±4.5 cm; CMJ: 37.4±3.1; CMJW: 43.7±3.9.Handball (N 13)-SJ: 35.3±5.8 cm; CMJ: 38.5±6.5; CMJW: 43.7±3.9.Volleyball (N 10)-SJ: 36.4±5.9 cm; CMJ: 40.1±6.7; CMJW 46.3±6.7), SPEED: Basketball-3.11±0.11s; Futsal-2.98±0.03s; Handball-3.11±0.17s; Volleyball- 3.00±0.18s.
For the female athletes the results were (VERTICAL JUMP: Basketball (N 12)-SJ: 26.6±3.1 cm; CMJ: 28.4±3.1; CMJW: 32.1±3.3. Futsal (N 10) - SJ 20.0±4.1 cm; CMJ: 23.9±4.5; CMJW: 28.2±3.1. Handball (N 12)-SJ 24.3±3.7 cm; CMJ: 26.6±4.1; CMJW: 31.0±5.1. Volleyball (N 7)-SJ 27.3±3.6 cm; CMJ: 30.9±3.7; CMJW 35.5±5.3. SPEED: Basketball-3.38±0.16s; Futsal-3.37±0.11s; Handball-3.43±0.13s; Volleyball- 3.36±0.18s. The statistical analysis revealed that there were no significant differences among the group means of the four types of teamsports considering either male or female subjects.
Discussion: Based on these results the used tests did not show differences when evaluating athletes from different types of team-sports. Despite the specificity of training and the characteristics of each sport, it was not possible to verify the differences caused by these aspects on such a young group of athletes.
