Background: Hand-grip strength has an important role in daily activities and serves as a reliable indicator of overall strength of body and health.
Aims: The purpose of present study was to determine the association between relative total hand grip strength and cardiorespiratory fitness of individuals who joined in Isfahan iron smelting factory recruitment tests.
Methods: Data were collected from 1010 men aged 20-35 years that participated in this study. The Right and Left-hand strength evaluated by dynamometer; cardiorespiratory fitness with 20m shuttle run test; push-ups; curl-ups; trunk strength and body fat percentage with valid tests and protocols. Relationship between relative overall hand-grip and cardiorespiratory index of individuals and other variables were examined using multiple linear regression.
Results: The regression analysis showed significant association between relative total handgrip strength (THGS) and cardiorespiratory fitness of participants adjusted by body mass index (r= 0.482; p=0.001) and body surface area (r= 0.207; p=0.001).
Conclusions: Data analysis revealed that hand-grip strength adjusted by body max index and body surface area could be an indicator of physical health and moderately reflect cardiorespiratory fitness in healthy young adults.
