Comparison Between Classic Leg-press Training and Complex Leg-press Training on a Dynamic Leg-press

Phase 2

Completed

• Conditions: Healthy
• Interventions: Other: resistance training; Other: complex resistance training

• Registration Number: NCT01451866
• Lead Sponsor: University of Applied Sciences of Western Switzerland

Brief Summary

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.

Detailed Description

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.

Arm && Interventions

Group	Intervention	Description
classic leg-press training	resistance training	Classic resistance training on the dynamic leg press. 6 x 8 repetitions at 60% 1 RM
Complex leg-press training	complex resistance training	Complex leg-press training with visual feed-back on a dynamic leg-press.

Primary Outcome Measures

Name	Time	Method
coordination	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

Secondary Outcome Measures

Name	Time	Method
Power	5 weeks	power measured on the dynamic leg press and with the squat jumps
Power - Endurance	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.
Balance	5 weeks	Balance measured with the Star Excursion Balance Test
