Heavy resistance training at retirement age induces 4-year lasting beneficial effects in muscle strength: a long-term follow-up of an RCT.

Objectives: Muscle function and size decline with age, but long-term effects of resistance training in older adults are largely unknown. Here, we explored the long-lasting (3 years) effects of 1 year of supervised resistance training with heavy loads.

Methods: The LIve active Successful Ageing (LISA) study was a parallel group randomised controlled trial at a university hospital in Denmark.
