The influence of closed or open grip type during a pull-up test to exhaustion

The aim of this study is to assess whether a closed (CG) or open grip (OC) can influence the maximum number of repetitions during the pull-up test to exhaustion. Ninety-five physically active males (age 23.5 ± 6.2 years, body mass 69 ± 7.9 kg, height 174.0 ± 6.4 cm, BMI 22.9 ± 2.2) randomly performed the pull-up test to exhaustion twice, once for each type of grip, one week apart. No significant difference (p = 0.092) was found between the maximum number of repetitions performed with the OG (14.2 ± 5.7) or the CG (13.9 ± 5.9). Spearman's correlation showed no significant association between participants' body mass and the number of repetitions (r = 0.128, p = 0.22 for OG; r = 0.157, p = 0.13 for CG). According to our results, the grip is not relevant in the determination of the performance during a pull-up test to exhaustion. Thus, using one grip instead of another may be recommended independently of performance needs. Grip type may be adapted considering the practised sport, and specific athletic requirements, as well as individual preference.
