Abstract: 

Background and Objective: Grip and pinch strength is a measure indicating the function of hand and is considered as a sign of general health. Work-related musculoskeletal disorders (WMSDs) are highly prevalent due to the incongruity of work with the workers. However, the diseases caused by such incongruity are preventable. Regarding this, the present study was conducted with the aim of investigating the relationship of maximum oxygen uptake (Vo2max) with grip and pinch strength and endurance.
Materials and Methods: This cross-sectional study was conducted on 120 male assembly workers using simple random sampling technique. The Vo2max, grip endurance and strength, as well as pinch endurance and strength were assessed by means of step test, dynamometer, and pinch gauge, respectively. The grip endurance was specified through determining the maximum time (in seconds) that one could continue applying one third of the maximum voluntary contraction. Data analysis was carried out using Pearson correlation coefficient in SPSS 20. P-value less than 0.05 was considered statistically significant.
Results: According to the results, Vo2max had a direct relationship with grip and pinch strength and endurance (P<0.05). Furthermore, Body Mass Index, age, and height showed a direct relationship with grip and pinch strength and Vo2max (P<0.05). However, grip endurance demonstrated no significant relationship with BMI and height (P>0.05). Additionally, there was a direct relationship between age and the endurance of grip and pinch (P<0.05).
Conclusion: As the findings indicated, in order to prevent WMSDs and enhance occupational efficiency, the individuals with high Vo2max should be employed in the jobs requiring high grip and pinch strength and endurance.
