Note: SD = Standard deviation; n = number; d = Cohen’s d effect size; SWD = Smallest worthwhile difference; CI = Confidence interval, HR = Heart rate; RPE = Rating of perceived exertion. The asterisks *, **, ***, and **** indicate the probabilities that the effect is possibly (>75%), likely (>90%), very likely (>95.5%), and most likely (=100%) higher or lower than the SWD. The letter u indicates an unclear effect with probabilities of >5% that the effect is both higher and lower than the SWD. The numbers in the brackets present the section of measurement within the circuit (Figure 1).
