Mixed
High-intensity strength training preserves functional gains (strength and mobility) for a longer duration during detraining compared to low-intensity training.
If you are an older adult who might have periods of inactivity due to illness or travel, prioritize high-intensity strength training. The strength and mobility gains you build are more likely to be preserved for over a year, whereas lighter training benefits may disappear within months of stopping.
All training induced gains in the LIST group had been abolished after four to eight months of detraining, whereas in the HIST group strength and mobility gains were maintained throughout detraining.
Why this rating
Longitudinal follow-up of 48 weeks post-training provides strong evidence for detraining effects.
Source
Strength training and detraining effects on muscular strength, anaerobic power, and mobility of inactive older men are intensity dependent
