Effect of 8 Weeks Endurance Training on Lipid Profile and Testosterone Levels in Young Judukas.

The present study examined the effects of endurance training on the lipid profile and testosterone levels in young male judokas. 18 judokas aged 18 to 21 years old participated in the study and were randomly divided into two groups: Exercise (n=9) and control group (n=9). The levels of LDL-C, HDL-C, TC, TG, and TT were measured in the blood samples of the subjects. No significant difference was detected in serum LDL-C in three stages of measurement (i.e. pre-, mid-, and post-test) (p=0.47); however, a significant difference was obtained in serum HDL-C during the three stages (p=0.03). There were no significant differences in serum TC (p=0.78) and TG (p=0.42). In Exercise group, TT levels was 18.98±12.45 in pre-test and it reached 20.56±5.76, but, it again reduced to 19.23±3.94 in Control group, TT levels was 18.76±6.98 in pre-test and it reached 20.35±14.87 while it dropped to 19.12±4.63. There were no significant difference between the stages in both groups (p>0.05).

Efeitos da prática sistemática do judô no tempo de reação de crianças / Efectos de la práctica sistemática de judo en el tiempo de reacción de los niños / Effects of judo systematic practice in children reaction time

O presente estudo avaliou o efeito da prática sistemática do judô no tempo de reação de crianças utilizando uma plataforma com recipientes enumerados de 1 a 3 a qual era ligada a um microcomputador. A tarefa consistia em transportar bolas de tênis em uma ordem pré-determinada e maior velocidade possível. Interpretou-se o tempo de reação como o intervalo do estímulo visual ao início da tarefa. A amostra foi compostapor 30 indivíduos divididos em três grupos (n=10), crianças não judocas, judocas e adultos. Foi encontrada diferença entre grupos determinando que não judocas apresentaram pior desempenho que judocas (p=0,04) e adultos (p=0,0002), não houve diferença entre judocas e adultos (p=0,09). Os resultados indicam que a prática sistemática é benéfica para o tempo de reação.
