ObjectivesTo determine the effect of 26 weeks of low-load high-repetition resistance training (BodyPumpâ¢) on maximal strength, gait speed, balance and self-reported health status in healthy, active middle-aged and older adults.DesignTwo-group randomised control trial.MethodsSixty-eight apparently healthy, active adults aged over 55 years completed either 26 weeks of BodyPump⢠training (PUMP) or served as control participants (CON). The BodyPump⢠group (n = 32, age = 66 ± 4 years) trained twice per week for 26 weeks while the control group (n = 36, age = 66 ± 5 years) continued with their normal activities. Leg-press and Smith-machine bench-press one repetition maximum (1RM), gait speed, balance, and self-reported health status were all assessed at baseline and follow-up.ResultsSignificant group-by-time interactions in favour of the BodyPump⢠group were found for leg-press 1RM (PUMP +13%, CON +3%, p = 0.007, partial eta2 = 0.11), Smith-machine bench-press 1RM (PUMP +14%, CON +5%, p = 0.001, partial eta2 = 0.18), normal gait speed (PUMP +23%, CON +9%, p = 0.028, partial eta2 = 0.08) and single leg balance right (PUMP +24%, CON â7%, p = 0.006, partial eta2 = 0.12). There were no group-by-time interactions for health status measures. Three participants in the BodyPump⢠group withdrew from training due to injury or fear of injury related to training.ConclusionsLow-load high-repetition resistance training in the form of BodyPump⢠is effective at improving maximal strength, gait speed and some aspects of standing balance in adults over 55 years. The training was well tolerated by the majority of participants.
