For every site, the comparison between HW and C was larger than between HE and C, and most of the grip strength differences in the HW group were statistically significant or almost significant.

The sentences
Namely, the HW group reached significantly higher grip strength differences (compared to the C group) in the first ( p = 0.012), pinch I/II + III + IV ( p = 0.021), and pinch I/II + III ( p = 0.015), while the pinch I/III ( p = 0.171) and pinch I/III + IV ( p = 0.068) showed a trend towards improvement in the HW group.
We reported that differences between grip strength measurements in both hands are evident after 8 weeks of hangboard training, with a superior effect of the maximizing weight protocol and an inferior effect of the minimizing edges protocol, which failed to reach significance.
