|Official Title:||Comparison of a Classic Leg-press Training Compared to a Complex Training on a Dynamic Leg-press With Visual Feed-back. Pilot-study|
- coordination [ Time Frame: 5 weeks ]coordination, i.e. sensorimotor capacity measured with (a) the difference between counter-movement jump and squat jump and (b) with a test for dynamic joint-position sense on the dynamic leg press
- Power [ Time Frame: 5 weeks ]power measured on the dynamic leg press and with the squat jumps
- Balance [ Time Frame: 5 weeks ]Balance measured with the Star Excursion Balance Test
- Power - Endurance [ Time Frame: 5 weeks ]Repeated power production during a repeated chair rise test where participants rise from a chair during one minute with two second rest between rises.

Active Comparator: classic leg-press training
Classic resistance training on the dynamic leg press. 6 x 8 repetitions at 60% 1 RM
Other: resistance training
hypertrophic resistance training
Experimental: Complex leg-press training
Complex leg-press training with visual feed-back on a dynamic leg-press.
Other: complex resistance training
complex resistance training with speed, excentric and power-endurance elements
The project evaluates two different resistance training programs on a leg press. One group will perform a standard resistance training with the aim of muscle hypertrophia, the other group will perform a complex resistance training combining rate of force development training, power training, speed endurance as well as sensorimotor aspects (i.e. following visual feedback to reproduce given forces or joint angles).
Hypotheses: Participants in the complex training group will change the relation between counter movement jump and squat jump, i.e. they will more improve in the counter movement jump because of improved sensorimotor capacity.
