Alpha level was set at 𝑃<0.05.
Superscripts (^a,b,c).
For a particular variable, mean values with different superscript are significantly (𝑃<0.05) different. Mean values with same superscripts are not significantly (𝑃>0.05) different. The pair of cell means that is significant has different superscripts.
Key:
𝑥: Mean.
SD: standard deviation.
SE: Static Endurance.
DE: Dynamic Endurance.
SRPE: rate of perceived exertion to Biering-Sørensen Test of Static Muscular Endurance.
DRPE: rate of perceived exertion to Repetitive Arch-Up Test.
