Fig. 6From: Effects of alternating heat and cold stimulation at different cooling rates using a wearable thermo device on shoulder muscle stiffness: a cross-over studyScatter diagram representing changes in muscle hardness and subjective symptoms in each condition. a Muscle stiffness. b Muscle fatigue. H3C1, alternating stimulation with 3Â min of heat and 1Â min of cooling. H3C2, alternating stimulation with 3Â min of heat and 2Â min of cooling. H3C3, alternating stimulation with 3Â min of heat and 3Â min of cooling. NO, no stimulation. * The value was calculated as the after intervention value minus the after typing valueBack to article page
