Study of the relationships between torso and lower limb muscle strength in young high level athletes with different specialties

Introduction

In the modern literature, more and more often an attempt is made to find any dynamic asymmetries of the lower extremities in high level athletes, while recently the importance of torso strength has begun to emerge. The primary purpose of this study was to evaluate the relationship of dynamic asymmetries of the lower limbs with the isometric strength of the torso muscles, in high level young Greek athletes of different sex and sports specialties. Secondly, an attempt was made to compare the different values of muscular strength of the lower limbs and torso with the different anthropomorphic characteristics of the athletes.

Material and methods

This is a cross-sectional study conducted on young high level athletes. The subjects were evaluated at the maximum torque produced by the flexors and knee extensions in isokinetic movement as well as at the maximum torque produced by isometric movement of the abdominal and dorsal muscles. Athletes' performance is recorded with the help of the Biodex 4 machine.

Results

The study population consists of 165 young high level athletes, of which 83 (50.3%) are boys and 82 (49.7%) girls, from 9 different sports. A statistically significant relationship was found between the extreme values of trunk force and the asymmetries of the lower extremities. 18% of the sample presented with clinically significant lower limb asymmetry exceeding 15%. No statistically significant relationship was found between inter limb asymmetry of lower extremities and torso asymmetry, with girls having greater inter limb asymmetries than boys. Karate athletes had the smallest torso asymmetries.

Conclusions

In conclusion, the study showed that there is a relationship between the dynamic asymmetry of the torso muscles and the asymmetry of the lower limbs, in young high-level athletes. Many athletes have developed large lower limb asymmetries that make them prone to injury. Girls appeared to have greater inter limb asymmetries of the lower limbs, compared to boys. Finally, the karate athletes presented the smallest torso asymmetries. More high-level studies are needed to document the torso-lower limb asymmetries relationship.
