The aim of this study was to compare motor performance in modified pull-up (MPU)and flexed knee push-up (FKPU) tests in young women. Thirty-five apparently healthy women (20.1±2.2 years) were submitted to each one of the tests at an interval of48 hours in a random balanced design. Most individuals performed between 0 an d 10 repetitions (86%) of the MPU test, and approximately 17% did not perform even one repetitions. On the other hand, the highest prevalence of outcomes for the FKPUtest was between 16 and 35 repetitions (71%). The Wilcoxon test identified statistically significant differences (p MPU). A moderate agreement (kappa =0.40) was found between the performance in both tests. Negative correlations of low magnitude (r=-0.23 to 0.46) were found between morphological variables (body weight,height, fat mass, and lean body mass) and motor performance in both tests. The results suggest that the FKPU test is presented as a better indicator ofmuscular endurance levels, where as the MPU test seems to better discriminate muscular strength in young women.

Este estudo investigou o efeito de um longo período de suplementação com creatina monoidratada (Cr m) sobre o trabalho total relativo (TTR) em esforços intermitentes máximos no cicloergômetro de homens treinados. Vinte seis indivíduos foram divididos aleatoriamente em grupo creatina (CR, n=13) e grupo placebo (PL, n=13). Os sujeitos receberam em sistema duplo-cego, doses de Cr m ou placebo-maltodextrina (20 g.d-1 por 5 dias e 3 g.d-1 durante 51 dias subseqüentes). Os grupos tiveram seus hábitos alimentares e sua condição física previamente controlados. Para determinação do TTR os sujeitos foram submetidos a protocolo de exercício em cicloergômetro composto de três Testes de Wingate de 30s separados por dois minutos recuperação, antes e após o período de suplementação. ANOVA, seguido pelo teste post hoc de Tukey, quando p
