Brief summary
To investigate the optimal training intensity for the improvement of muscle power during high velocity resistance training in older men and women
Interventions
Participants were randomised to explosive resistance training at 20%, 50%, or 80% of maximum dynamic muscle strength (1RM) or a non-training control group for 8-12 weeks. Participants randomised to training groups, exercised twice a week performing 3 sets of 8 rapid concentric/slow eccentric repetitions for 5 exercises (leg press, chest press, leg extension, seated row, leg flexion) using Keiser pneumatic resistance training machines. Control group participants maintained their usual physical a
