The use of varying creatine regimens on sprint cycling.

This study aimed to determine the effects of different acute creatine loadings (ACRL) on repeated cycle sprints. Twenty-eight active subjects divided into the control (n=7) and the experimental (n=21) group. The exercise protocol comprised three 30s Anaerobic Wingate Tests (AWT) interspersed with six minutes recovery, without any supplements ingested and following placebo and creatine ingestion, according to each ACRL (40g, 100g and 135g throughout a four-day period).

Effects of a physical activity program. The study of selected physical abilities among elderly women.

This study evaluated the effects of a 12-week exercise program on the physical abilities of 55 sedentary women ages 60 to 75. The variables tested were dynamic balances, muscular endurance, sit and reach flexibility, and muscular coordination. Participants were grouped into three exercise groups (n = 45) and one control group (n = 10).
