Jump Rope Training and Shoulder Isokinetics in CrossFit

NCT06924775 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 18

No results posted yet for this study

Summary

The goal of this quasi-experimental clinical trial is to evaluate whether weighted jump rope (WJR) training can improve the isokinetic shoulder strength profile in male and female CrossFit practitioners.

The main questions it aims to answer are:

* Does six weeks of WJR training affect internal and external shoulder rotational peak torque relative to body mass?
* Does WJR influence the external/internal shoulder rotation ratio in dominant and non-dominant arms at varying angular velocities? Researchers will compare pre- and post-intervention isokinetic measurements to see if WJR training leads to significant changes in shoulder strength and balance.

Participants will:

* Incorporate WJR sessions three times per week into their usual CrossFit training.
* Undergo isokinetic testing of both shoulders at baseline and post-intervention at 60°/s, 180°/s, and 300°/s.
* Have their training adherence and technique monitored throughout the study.

Conditions

  • Evaluation of the Effects of Weighted Jump Rope Training on the Isokinetic Shoulder Profile in CrossFit Practitioners

Interventions

OTHER

Weighted jump rope training

Unlike isolated jump rope studies, this intervention was embedded within the participants' habitual CrossFit routine, enhancing ecological validity. Performing the jump rope protocol immediately prior to regular training-rather than as a stand-alone session-was intended to promote warm-up and neuromuscular priming benefits. The use of a weighted rope introduced a resistance stimulus that is rarely incorporated in jump rope interventions.
