Q: DOES SELF-SELECTION OF RESISTANCE LOAD SHOW MERIT?

A: Many trainers establish a client’s one-repetition maximum (1-RM) to estimate appropriate intensity for resistance training. However, research published in 2017 suggests that allowing female clients to self-select their load based on rating of perceived exertion is a workable alternative to using 1-RM.

Researchers recruited 20 women (aged 23 ± 3) who performed three exercise sessions 72 hours apart. In the self-select session, subjects were free to adjust the weight to provide a comfortable yet challenging workout. Their average loads corresponded to 57% of 1-RM.

The researchers concluded that self-selected loads are effective at eliciting a muscular response in trained women and that RPE is an accurate gauge of resistance exercise intensity. Note that previous research has found that women who self-select their resistance loads demonstrate greater intent and self-efficacy than those who rely on imposed loads.
