Associations Between Pulmonary Function and Muscle Strength in Turkish National Karate Athletes

Area of Science:

• Sports Science
• Physiology

Background:

• Respiratory efficiency is vital for sustaining muscular performance in high-intensity sports.
• Karate demands significant physical exertion, making respiratory function a key performance factor.

Purpose of the Study:

• To investigate the association between pulmonary function and isometric muscle strength in elite karate athletes.
• To determine the predictive capacity of pulmonary parameters for muscle strength in this population.

Main Methods:

• 23 national-level karate athletes underwent pulmonary function testing using a digital spirometer.
• Isometric muscle strength was measured for handgrip, lower back, and legs using a dynamometer.
• Correlation and linear regression analyses were performed to assess relationships and predictive power.

Main Results:

• Significant, large to very large correlations (r=0.639-0.812, p<0.01) were found between pulmonary function and isometric strength.
• Pulmonary function explained 27%-67% of the variance in isometric strength (p<0.05).
• Multiple regression showed pulmonary function predicted 71% of handgrip strength variance, 47% of leg strength, and 71% of back strength variance (p<0.05).

Conclusions:

• Strong associations exist between pulmonary function and isometric muscle strength in elite karate athletes.
• Pulmonary health and respiratory muscle function are critical for athletic performance in karate.
• Further research is needed to understand underlying mechanisms and optimize training for performance.
