Relationship between anthropometric variables and elbow flexor muscle strength at varying hip joint angle in apparently healthy young adults

Abstract

Elbow flexor muscle strength testing and evaluation is an integral component of treatment programmes for musculoskeletal problems involving the elbow joint in Orthopaedic and Physiotherapy practice. The primary aim of this study was to investigate the relationship between anthropometric variables and the elbow flexor muscle strength at different testing positions.

Material and Method. A total of 210 participants (males=105, females=105) voluntarily participated in the study. The anthropometric indices were measured using standardized procedures. The elbow flexor muscle strength was assessed using an adapted cable tensiometre.

Results. The result showed that significant correlation was found between elbow flexor strength (assessed at four different positions), body weight and arm girth among male and female participants as well as height and forearm length among the females. There was significant gender difference in elbow flexor strength at all hip angles.

Conclusion. Height, body weight, arm- forearm length and arm girth are directly related with elbow flexor muscle strength of apparently healthy young adults. During muscle strength testing or strengthening programme, significant consideration should be given to anthropometric variables of subject or patient.
