Chronic blockade of histamine H-1/H-2 receptors impairs microvascular and mitochondrial adaptations to interval training in humans, leading to blunted functional adaptations in exercise capacity, glycemic control, and vascular function. This suggests that histamine H-1/H-2 receptors play a crucial role in the integrative exercise training response in humans, potentially affecting post-exercise muscle perfusion regulation.
Exercise training is a powerful strategy to prevent and combat cardiovascular and metabolic diseases, although the integrative nature of the training-induced adaptations is not completely understood. We show that chronic blockade of histamine H-1/H-2 receptors led to marked impairments of microvascular and mitochondrial adaptations to interval training in humans. Consequently, functional adaptations in exercise capacity, whole-body glycemic control, and vascular function were blunted. Furthermore, the sustained elevation of muscle perfusion after acute interval exercise was severely reduced when H-1/H-2 receptors were pharmaceutically blocked. Our work suggests that histamine H-1/H-2 receptors are important transducers of the integrative exercise training response in humans, potentially related to regulation of optimal post-exercise muscle perfusion. These findings add to our understanding of how skeletal muscle and the cardiovascular system adapt to exercise training, knowledge that will help us further unravel and develop the exercise-is-medicine concept.
