Key result
Passive stretch of the human calf muscles decreases cardiac vagal outflow and spontaneous baroreflex sensitivity irrespective of prior exercise intensity (P<0.05).

May suppress vagal tone during passive stretch in healthy subjects; leaves open clinical relevance during recovery or in disease.
Does passive calf muscle stretch alter spontaneous baroreflex control of heart rate and vagal tone during graded metaboreflex activation in healthy subjects?
p-value: p=<0.05
Passive stretch of the human calf muscles decreases cardiac vagal outflow irrespective of the levels of blood pressure increase caused by muscle metaboreflex activation.
Drew et al. (2007) studied Healthy (n=10). Passive calf muscle stretch vs. Control trial (0% exercise) and circulatory occlusion alone was evaluated on Spontaneous baroreflex sensitivity (SBRS) and heart rate (p=<0.05). Passive stretch of the human calf muscles decreases cardiac vagal outflow and spontaneous baroreflex sensitivity irrespective of prior exercise intensity (P<0.05).
