Avaliação dos efeitos do treinamento no período preparatório em atletas profissionais de futebol

O objetivo do presente estudo foi avaliar os efeitos do treinamento no período preparatório em atletas profissionais de futebol. Participam 17 atletas, com idade acima de 18 anos que disputaram a terceira divisão do campeonato paulista, em 2009. O programa de treinamento predominante foi o tipo neuromuscular e por meio dos testes de sentar e alcançar, salto sêxtuplo, salto vertical e velocidade de deslocamento em 30m os atletas foram avaliados antes do início do programa de treinamento (M1) e após sete semanas (M2). Os dados coletados foram armazenados em banco computacional, produzindo-se informações no plano descritivo (medidas de centralidade e dispersão) e, no inferencial, Teste t de Student e Anova One-way. Os principais resultados apontam para melhora da flexibilidade, força explosiva e rápida, e sensível diminuição na velocidade de deslocamento em 30 metros.

Etapas e volume de treinamento das ginastas Brasileiras participantes de Jogos Olímpicos (1980-2004)

Results from Brazilian female Artistic Gymnastics improved over the past 10 years at an international level of competition. This study aimed at describing career development process in sports through a qualitative research resorting to the Oral History method. Ten Brazilian gymnast players in Olympic Games from 1980 to 2004 participated in the study. The information they provided allowed for the identification of specific variables present in their long term preparation: structure and organization of their practice, duration of the preliminary preparation phases, volume of daily practice in different phases of training, and length of time for the achievement of better results. © FTCD/CIDESD.

Ocorrência de lesões de ligamentares e músculo tendíneas ao longo das fases do ciclo menstrual de atletas de alto redimento: um estudo de caso longitudinal

Female athletes are more susceptible to injury when compared with males. This increased risk of injury, may be caused by fertile-menstrual cycle. The aims of this study were to investigate the prevalence in the occurrence of muscle-tendon and ligament injuries in different phases of the menstrual cycle over a period of high performance sports training and identify possible differences of occurrences between the phases. Fifteen female athletes, members of a women's basketball team, with ages between 15 and 22 years (average 17.5 ± 2.6 years), with regular menstrual cycles and daily practitioners of training, received follow-up during the menstrual cycle for 5 months. During the period were noted occurrences of injury in relation to the menstrual period of each athlete. The results showed 13 injuries, all of anterior cruciate ligament. The distribution of percentage values indicated a significantly higher risk of athletes suffer injuries in the follicular phase. The result makes us believe that significant elevations in the concentrations of estrogen in this fertile menstrual cycle phase, more open women to a higher risk of performing different injuries.

Psychological, biochemical and physiological responses of Brazilian soccer players during a training program

Aims of the study. - The aim of this study is to investigate the behavior of the physiological, biochemical and psychological parameters in Brazilian soccer players during a training program.Materials. - Fifteen athletes were evaluated at the beginning (T1), in the middle (T2) and at the end (T3) of the training program. on the first day, at 7:30 am, before the blood collecting at rest for the determination of serum creatine kinase (CK), serum creatinine and serum urea, the athletes had their psychological parameters assessed by the profile of mood state questionnaire (POMS). After 90 min, they performed a 250-m sprint. on the second day at 8:30 am, the athletes had their alactic anaerobic performance measured and, after 40 min, they completed the aerobic test. Friedman test was used to verify the behavior of overtraining markers.Results. - There was a decrease in vigor score in T3 (p=0.01) compared with T1 and T2. In T3 (p=0.01), the athletes also showed an increase in serum creatinine levels compared to T1. Furthermore, in the same period, we verified a diminishing in the team performance.Conclusion. - The training program developed between T2 and T3 led to the fall of the vigor score, the increase in serum creatinine concentrations and the diminishing in team performance.
