Ad = Advanced; Hi = Highly-advanced; Δ = Difference between PRE and POST; Sign. = Level of significance; ES = Effect size (Cohen’s d); rel. = relative to body weight. Levels of significance were only calculated for changes from PRE to POST in the placebo group and marked as follows: *= p ≤ 0,05; **= p ≤ 0,01; ***= p ≤ 0,001). Significant differences between group were marked as follows: # = p ≤ 0,05; ##; p ≤ 0,01; ### = p ≤ 0,001.
