Clinical Trial Summary

Current evidence suggests resistance exercise as the primary therapeutic strategy to prevent age-related functional decline. The National Strength and Conditioning Association recently stated that a properly designed resistance exercise program should include power exercises performed at higher velocities in concentric movements with moderate intensities. We should be aware that not all older adults are easily motivated to train in unfamiliar gym-based settings with high subscription fees. Therefore, implementation of traditional gym-based resistance exercise at a large scale has been found to be difficult. Interestingly, we have previously shown that the use of high external loads, which implies the need for specific facility memberships, is not necessary to induce neuromuscular gains. This provides strong support for home-based training intervention strategies. Stair climbing or stepping-based exercise constitute a promising avenue to ameliorate the cost-effectiveness and implementation potential of resistance exercise in older adults. Such exercises can induce muscular activation levels similar to high-load resistance exercise and result in similar or even better gains in muscle mass, strength and power compared to slow-speed resistance exercise when properly designed. However, the (neuro)-muscular effects of stair climbing exercise have never been compared to the more optimal power-oriented resistance exercise, which is the primary aim of this study. The secondary aim of this study is to examine if stair climbing exercise also has beneficial effects on cognition.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	F-V profile	Force-velocity profiling is carried out unilaterally (dominant leg) on the pneumatic leg press device (Leg Press CC, HUR, Kokkola, Finland). The test protocol consists of a maximal isometric test (knee joint angle = 85°, hip angle = 55°; 3 attempts of 3s), followed by explosive concentric leg extensions at gradually increasing loads (unloaded, 15%, 30%, 45%, 60%, 75% of the maximal isometric force, 2-3 attempts per load, and additional single repetitions until one-repetition maximum is reached). Mean velocity of the best trial per load is used to estimate the individual F-v relationship through a linear equation. This F-v relationship will be used to examine the exercise-induced adaptations. F0 (maximal force), v0 (maximal velocity), a (the equation's slope), Pmax (maximal power) and the corresponding v and F at Pmax are used for the analyses.	Change from baseline in F-v profile at 12 weeks
Secondary	Gait speed	The average speed to walk 10m as fast as possible (in m/s)	Change from baseline in gait speed at 12 weeks
Secondary	5-repetition sit-to-stand time	The time (s) needed to perform 5 sit-to-stand transitions.	Change from baseline in sit-to-stand performance at 12 weeks
Secondary	5-repetition sit-to-stand power	The power (watt) needed to perform 5 sit-to-stand transitions.	Change from baseline in sit-to-stand performance at 12 weeks
Secondary	Stair ascent time	The time (s) needed to ascend a flight of stairs.	Change from baseline in stair climbing performance at 12 weeks.
Secondary	Stair ascent power	The power (watt) needed to ascend a flight of stairs.	Change from baseline in stair climbing performance at 12 weeks.
Secondary	Countermovement jump height	Jump height (cm) in a countermovement jump	Change from baseline in countermovement jump height at 12 weeks.
Secondary	MoCA test score	Total score (min 0, max 30, higher scores indicate better performance) on the Montreal Cognitive Assessment test	Change from baseline in Montrial Cognitive Assessment test score at 12 weeks.
Secondary	Digit Span Test score	Total score (min 0, max 30, higher scores indicate better performance) on the Digit Span Test	Change from baseline in Digit Span Test score at 12 weeks.
