Key result
A 6-week 4x4 cycle ergometer HIIT protocol prescribed using %HRmax effectively increased lower-limb power, strength, and functional capacity in active older adults.
Why the study?
Does a 6-week 4x4 cycle ergometer HIIT protocol prescribed using %HRmax improve lower-limb power/strength and functional capacity in active older adults?
Does a 6-week 4x4 cycle ergometer HIIT protocol prescribed using %HRmax improve lower-limb power/strength and functional capacity in active older adults?
p-value: p=0.034
A 6-week cycle ergometer HIIT protocol using age-predicted HRmax is feasible and effective for improving lower limb strength and functional capacity in older adults without requiring excessive oversight.
Supports 6-week cycle HIIT for lower-limb strength gains in older adults; hypothesis-generating pending randomized confirmation.
= 0.034) also presented significant differences pre- to post-intervention. There was a 96% participant session completion rate. These data imply that a simple 4x4 cycle ergometer HIIT protocol prescribed using a %HRmax is effective at increasing lower-limb power/strength and can be used in the general older adult population without excessive oversight. Our intervention protocol demonstrates that 6 weeks of cycle ergometer HIIT is an adequate amount of time to result in lower limb strength and functional capacity improvements in active older adults.

Keating et al. (2022) studied active older adults. 4x4 cycle ergometer HIIT protocol prescribed using %HRmax vs. pre-intervention baseline was evaluated on lower-limb power/strength and functional capacity (p=0.034). A 6-week 4x4 cycle ergometer HIIT protocol prescribed using %HRmax effectively increased lower-limb power, strength, and functional capacity in active older adults.
