Objective:

To investigate the effect of a 12-wk weighted-jump-rope training program on shoulder strength.

Design:

Pretest to posttest experimental design.

Setting:

University sports physiotherapy laboratory.

Participants:

24 healthy volleyball players age 13-16 y.

Intervention:

Group 1 took weighted-rope training (n = 9), group 2 took unweighted-rope training (n = 8), and group 3 did not train with any specific program (n = 7).

Main Outcome Measures:

Players’ strength determined with an isokinetic dynamometer (Isomed 2000) at 180 and 60°/s on external and internal rotators, supraspinatus peak torque, and total work of the dominant shoulder. Kruskal–Wallis and Mann–Whitney U tests were used to determine the difference among the groups.

Results:

At pretraining evaluation, there were no significant differences in the test scores of the isokinetic test of full can and empty can between the groups at 60 and 180°/s. There was no statistically significant difference for 60 and 180°/s between pretraining and posttraining assessment (P > .05) except that total eccentric work increased in groups 1 and 3 but decreased in group 2 at 180°/s during the full can (P < .05). There was no significant difference among the groups between the pretraining and posttraining testing at both 180 and 60°/s for the empty can (P > .05). Internal-rotation values at 60 and 180°/s decreased for both peak torque and total work for all groups. External-rotation peak torque and total work at 60°/s increased for group 1. External-rotation peak torque and total work at 180°/s increased for all groups.

Conclusions:

The results indicate that a jump-rope training program is a good conditioning method for overhead athletes because of its potential benefits to shoulder strength.

Bone remodeling as a response to exercise in human subjects is described in the literature, although most studies treat exercise as a qualitative factor contributing to bone remodeling. Quantitative description requires assessment of the mechanical loads on the bones. This work describes a generalized lower extremity model that uses existing musculoskeletal modeling techniques to quantify mechanical variables in the femoral neck during exercise. An endurance exercise program consisting of walking, jogging jumping rope, and weight-training was analyzed. Peak femoral neck cortex stresses and strains were high during jogging and squatting, compared to walking, whereas jumping rope and other weight-training exercises produced peak stresses comparable to or lower than walking. Peak stress and strain rates were significantly higher for walking, jumping rope, and jogging than for weight-training. The model should prove useful for any study investigating a quantitative relationship between exercise and bone remodeling.
