A comparison of once- and twice-weekly eccentric training on muscular health of older adults

INTERVENTION: Parallel randomisation was performed using a random number generator online. The non‐active control group maintained normal living conditions whereas the two training groups performed multi‐joint isokinetic eccentric exercise for 12 weeks at 50% of their maximum eccentric strength. The once‐weekly training group trained once per week and the twice‐weekly training group trained twice per week; training volume was not matched between groups. The training lasted for 7 minutes in week 1 and progressed to 12 minutes in week 4, which remained the same hereafter until the training programme was completed in week 12. Participants were assessed at baseline, mid‐training (week 7) and post‐training (week 13). CONDITION: Improving neuromuscular structure and function in healthy older adults ; Musculoskeletal Diseases PRIMARY OUTCOME: Lower‐limb muscular strength measured via dynamometry at baseline, mid‐training (week 7) and post‐training (week 13) SECONDARY OUTCOME: ; 1. Lower‐limb muscular power measured using the 10‐repetition sit‐to‐stand test at baseline, mid‐training (week 7) and post‐training (week 13); 2. Vastus lateralis muscle thickness measured using B‐mode ultrasonography at baseline, mid‐training (week 7) and post‐training (week 13); INCLUSION CRITERIA: 1. =60 years of age 2. Able to independently ambulate without walking aids 3. Free from any illnesses and/or medication that affected the neuromuscular system or balance 4. Not currently involved in a structured exercise programme
