Fig. 3From: Local alternating heat and cold stimulation affects hemodynamics and oxygenation in fatigued muscle tissue and autonomic nervous activity: a single-arm interventional studyScatter diagram representing change in TOI and change in LF/HF. *Value was calculated as the pre-intervention value minus the post-intervention value. TOI, tissue oxygenation index; LF, low frequency; HF, high frequencyBack to article page
