Abstract

Objectives

To report hip adduction, abduction, and adduction:abduction strength ratio values in NCAA Division I American football players, and to compare strength values across position groups.

Design

Cross-sectional study.

Setting

University training facility.

Participants

85 male football players.

Main outcome measures

Isometric hip adduction and abduction strength values in the 0° hip-flexion long-lever and 0° hip-flexion short-lever testing positions, using a ForceFrame.

Results

Hip strength values are presented across two testing positions. ANOVA revealed significant differences (p ≤ 0.05) in hip strength between position groups, with medium-to-large effect size (n² = 0.116–0.284). Skill-position and mid-position players demonstrated significantly greater hip adduction and abduction relative strength in both testing positions, when compared to lineman-position players. In addition, skill-position and mid-position players demonstrated significantly greater hip adduction:abduction strength ratios (0.19–0.20, 24–25%) in the long-lever testing position, when compared to lineman-position players, with large effect size (n² = 0.178). No significant differences in strength were observed between skill-position and mid-position players. Hip adduction:abduction strength ratios ranged from 0.68 to 0.88 in the long-lever testing position and 1.05 to 1.09 in the short-lever testing position.

Conclusion

Significant differences in relative strength exist between position groups of NCAA Division-I football players, in hip adduction, abduction and adduction:abduction ratio.

期刊介绍： Physical Therapy in Sport is an international peer-reviewed journal that provides a forum for the publication of research and clinical practice material relevant to the healthcare professions involved in sports and exercise medicine, and rehabilitation. The journal publishes material that is indispensable for day-to-day practice and continuing professional development. Physical Therapy in Sport covers topics dealing with the diagnosis, treatment, and prevention of injuries, as well as more general areas of sports and exercise medicine and related sports science. The journal publishes original research, case studies, reviews, masterclasses, papers on clinical approaches, and book reviews, as well as occasional reports from conferences. Papers are double-blind peer-reviewed by our international advisory board and other international experts, and submissions from a broad range of disciplines are actively encouraged.
