Notes. EG = experimental group; CG = control group; HR = heart rate; Fatigue = subjective fatigue of the performing hand (scale from 0 to 10). HR 1 + fatigue 1: before baseline; HR 2: three minutes after acute exercise; HR 3 + fatigue 2: after practice session immediately after intervention; HR 4 + fatigue 3: after practice session 30 minutes after intervention; fatigue 4 + 5: before and after practice session 24 h after intervention.
