Training Programs Effects on Strength and Balance in Older Adults

The a-priori power analysis calculation reported a total sample size of 51 participants. We decided to increase the sample size of approximatively 20% hypothesizing an increment of drop-outs due to the not completely solved COVID-19 pandemic at the time of the study. In this single-blinded randomized controlled study, both intervention groups received 24 training sessions of 45 minutes each, twice a week for 12 weeks.The two intervention groups and the control group were tested at the baseline (T0), after six weeks (T1), and after twelve weeks (T2). Subjects of the intervention groups had to complete at least 21 out of 24 training sessions. Moreover, all subjects had to complete all the assessments. Otherwise, they were completely excluded from the data analysis.
