RESUMO
O objetivo consistiu em investigar os efeitos das fases do Ciclo Menstrual (CM) em variáveis da aptidão física e a percepção subjetiva do esforço em mulheres jovens. Para tal, foram recrutadas 11 mulheres universitárias, que foram submetidas a testes de potência e de força dos membros superiores e inferiores e de aptidão aeróbica nas fases Folicular, Ovulatória e Lútea. Foram aplicados os testes de Arremesso de Medicine Ball, Salto Vertical e Horizontal, potência aeróbica (YoYo IRT) e de Força Máxima (1RM). Os resultados indicam que não houve diferenças significativas (p>0,05) nos testes de aptidão física entre fases do CM. Concluímos que as diferentes fases do CM não influenciam o desempenho de componentes da aptidão fí- sica, seja em aspectos neuromusculares ou na potência aeróbica.
The objective was to investigate the effects of the different phases of the Menstrual Cycle (CM) on physical fitness variables in young women. For that, 11 university women were recruited, who underwent power and strength tests for upper and lower limbs and aerobic fitness tests at Follicular, Ovulatory and Luteal phases. Medicine Ball Throw, Vertical and Horizontal Jumps, aerobic power (YoYo IRT) and maximum strength (1RM tests). The results indicate that there were no significant differences (p> 0.05) in physical fitness tests between any of the CM phases. We conclude that the different phases of CM do not influence the performance of physical fitness components, either in neuromuscular aspects or in aerobic power.

Para eso, fueron reclutadas 11 mujeres universitarias, que fueron sometidas a pruebas de potencia y fuerza de los miembros superiores e inferiores y de aptitud aeróbica en las fases Folicular, de Ovulacióny Lútea.

Los resultados indican que no hubo diferencias significativas (p>0,05) en las pruebas de aptitud física entre las fases del CM. Concluimos que las diferentes fases del CM no influyen en el desempeño de los componentes de la aptitud física, sea en aspectos neuromusculares o en la potencia aeróbica.

OBJECTIVES: To assess the prevalence of non-responders to different tests and to compare the effects of different resistance training (RT) volumes on muscle strength, anthropometric and functional performance of older women. METHODS: Three hundred seventy six women performed 12weeks of RT with either low or high volume (LV, 71.29±5.77years and HV 69.73±5.88years, respectively). Both groups performed the same exercises, and all parameters were held constant except for the number of sets performed per week. LV performed 8-12 for upper and 4-6 for lower body, while HV performed 16-20 and 8-10, respectively. Before and after the training period, the participants were tested for bench press and leg press 1RM, 30-s chair stand, 30-s arm curl, six-minute walk test, sit and reach, body weight and waist circumference. RESULTS: Both groups significantly improved in all strength and functional tests and reduced their body weight and waist circumference. ANOVA revealed higher gains in the leg press 1RM, 30-s arm curls and 6-min walk test for the HV group and higher increases in the results of the sit and reach test for the LV group. However, the differences were negligible and may be attributable to a type I error due to the large sample size. Non-responsiveness was not apparent in any subject, as a positive response on at least one outcome was present in every participant. CONCLUSIONS: Our results suggest that RT, even at low volume, improves waist circumference, muscle strength and physical function in the older population, with no evidence of non-responsiveness. Therefore, we should not be restrictive in prescribing this type of exercise to this population.
