This study aimed to determine the impact of sex on the differences and relationships of the one-repetition maximum (1RM) performance between three overhead pressing exercises (push press, push jerk and split jerk). 15 males (body mass: 82.3 ± 9.9 kg; weightlifting training experience: 2.6 ± 1.6 years) and 15 females (body mass: 64.4 ± 7.0 kg; weightlifting training experience: 2.2 ± 1.4 years) participated in this study. A ratio scaled (1RM/body mass) was utilized for the comparison between males and females.The 1RM of the three exercises were evaluated within the same testing session using a combined 1RM assessment method. The interaction effect of exercise and sex did not reach statistical significance (p=0.671;  2 =0.001), whereas significant main effects of exercise and sex with medium (p<0.01;  2 =0.096) and large effect sizes (p<0.001;  2 =0.306) were revealed. A similar main effect of exercise was reported for both malesand females (push press [0.8 ± 0.1] < push jerk [0.9 ± 0.2] ~ split jerk [0.9 ± 0.2]). The 1RM performance of the three exercises were significantly correlated for males (r [range] = 0.856-0.963) and females (r [range] = 0.636-0.925). These results suggest that sex does not impact the differences in the 1RM performance across weightlifting overhead pressing exercises. However, greater correlations and lower range variations in the 1RM performance during the push press, push jerk and split jerk are expected for males in comparison to females.

Purpose: The aim of the current study was to investigate the relationship between dive distance (DD) and countermovement jump (CMJ) height, track start CMJ height, countermovement broad jump (CMBJ) distance, track start broad jump distance, and isometric midthigh pull peak force and relative peak force. Methods: A total of 27 (11 female and 16 male) regional-national-international-standard swimmers (mean [SD]; age = 19.5 [5.5] y; mass = 69.3 [10.5] kg; height = 1.77 [0.09] m) performed 3 trials of a track start dive, CMJ, track start CMJ, CMBJ, track start broad jump, and isometric midthigh pull. Results: Data were separated into pooled (females and males combined), females, and males. Large to very large correlations were found between DD and all variables tested for pooled data (r = .554–.853, P < .001–.008), with DD-CMBJ displaying the highest correlation (r = .853, P < .001). CMBJ accounted for 70% of the variance in DD. Females demonstrated moderate nonsignificant correlations between DD isometric midthigh pull (r = .379, P < .125). Males demonstrated very large significant correlations between DD-CMJ (r = .761, P < .001). Conclusions: DD demonstrated strong correlations with jump performances and multijoint isometric force production in pooled data. Males showed stronger correlations than females due to being stronger and being able to perform the jumping/strength tasks to a higher standard. Enhanced jump performance and increased maximal force production may, therefore, enhance DD in swimmers.
