Background and Objective: Grip and pinch strength is a measure indicating
the function of hand and is considered as a sign of general health. Workrelated
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.
