Brief Summary

The new training device, the eccentric arm-crank, will be examined for its training effects in athletes with a spinal cord injury (SCI) by this project. That the training device can be used in patients with paraplegia in the future, the so-called "testing of the applicability of this concept" will be carried out during this study. Fourteen volunteer, healthy athletes with SCI are first tested for their upper body performance, followed by a training phase over 20 trainings and at the end the performance data is collected again. The training intensity and duration is continuously increased during the training phase.

Eccentric Training

EXPERIMENTAL

This Group will train on the KREHA for 20 Trainings

Other: eccentric arm-cranking training

Interventions

eccentric arm-cranking training OTHER

Over the twenty training sessions, able-bodied participants will exercise on the KREHA device. An arm-crank has to be decelerated, which will be rotated by a prematurely defined revolution rate and training duration. During this intervention a certain power has to be applied. During the whole time of training a continous progression in power and training duration is applied.
