A complex training on a dynamic leg-press with visual feed-back will improve coordinative capacity, power, sensorimotor and cognitive aspects more than a classic training on the same leg-press but without visual feed-back.
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.

coordination
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
Time frame: 5 weeks
Power
power measured on the dynamic leg press and with the squat jumps
Time frame: 5 weeks
Balance
Balance measured with the Star Excursion Balance Test
Time frame: 5 weeks
Power - Endurance
Repeated power production during a repeated chair rise test where participants rise from a chair during one minute with two second rest between rises.
Time frame: 5 weeks
