Clinical Trial Summary

Ageing in humans is accompanied by a progressive decline in lower-limb muscle power production. In addition to a decline in musculoskeletal fitness, ageing is associated with a reduction in cardiovascular and metabolic fitness. Therefore, if exercise interventions aim for a high impact on the overall health status of middle-aged and older adults, they should combine endurance, high-intensity interval training and muscular strengthening activities. Recreational football training combines all these training components, which implies that it could constitute an adequate training modality for participants of all ages. What remains to be investigated in more detail, is whether recreational football training can improve muscle power production in middle-aged to older adults and whether this potential improvement is present across the full force-velocity (F-V) profile. Next to a detailed analysis of the leg-extensor F-V profile as primary outcome, simultaneous effects on functional capacity, body composition and endurance exercise capacity were investigated. In addition, feasibility and the physical demands (internal and external load indicators) of the training program were tracked throughout the intervention period.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Maximal power	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. Maximal power is used for the analyses.	Time Frame: Change from baseline in maximal power (watt) at 12 weeks
