Autonomic nervous activity and lipid oxidation postexercise with capsaicin in the humans.

چکیده
This study evaluated the synergistic effects of acute exercise with capsaicin (200mg) upon the restoration of cardiac autonomic functions and depolarization- repolarization interval as well as substrate oxidation. Nine healthy males [21.9(0.8) yrs] volunteered for this study. Cardiac autonomic activity, metabolic responses, and the ECG QT intervals were continuously measured during 5 min at rest and postexercise recovery after 30 min exercise at 50% VO2max on a stationary ergometer with placebo (ECON) or capsaicin intake (ECAP), and no exercise control (NCON) were randomized. Results indicated that the HF power reflecting parasympathetic activity significantly returned to the baseline much faster during ECAP than ECON trial during postexercise [122.1 (23.2) vs. 60.2 (11.7) %, p < 0.05]. The ECAP trial significantly decreased RQ [0.79(0.02) vs. 0.85 (0.03), p < 0.05] with significantly greater fat oxidation [69.3 (6.0) vs. 49.4 (10.8) %, p < 0.05] in comparison to NCON trial during 120 min postexercise recovery without any adverse effects on cardiac electrical stability as determined by trigger-averaged ECG QT interval analyses. We suggest that capsaicin before the exercise may contribute to the improvement of cardio-protective functions and metabolic responses as one of the beneficial supplements accelerating faster restoration of autonomic activity and enhanced lipolysis during postexercise recovery without any adverse effects on cardiac electrical stability. Key pointsCapsaicin before exercise may contribute to the improvement of cardio-protective functions as one of the beneficial supplements accelerating faster restoration of autonomic activityCapsaicin before exercise enhanced lipolysis during postexercise recovery periodCapsaicin intake does not influence cardiac electrical stability during recovery period.

Alterations of autonomic nervous activity and energy metabolism by capsaicin ingestion during aerobic exercise in healthy men.
We investigated whether capsaicin ingestion (150 mg) enhances substrate oxidation associated with thermogenic sympathetic activity as an energy metabolic modulator without causing prolongation of the cardiac OT interval during aerobic exercise in humans. Ten healthy males [24.4 (4.3) y] volunteered for this study. The cardiac autonomic nervous activities evaluated by means of heart rate variabi...

Various lines of published evidence have already demonstrated the impact of TRPV1 agonists on energetic metabolism through the stimulation of the sympathetic nervous system (SNS). This study presents a trial investigating if stimulation of the two related sensory receptors TRPA1 and TRPM8 could also stimulate the SNS and impact the energetic metabolism of healthy subjects. The trial was designe...

We investigated the effects of capsaicin supplementation (150mg) on alterations of autonomic nervous system (ANS) activity associated with adverse effects of cardiac depolarization-repolarization intervals during aerobic exercise in obese humans. Nine obese males (26.1 ± 1.5 yrs) volunteered between study designed. The cardiac ANS activities evaluated by means of heart rate variability of power...

NEW FINDINGS What is the topic of this review? The autonomic nervous system plays a key role in bringing about the cardiovascular responses to exercise necessitated by the increased metabolic requirements of the active skeletal muscle. The complex interaction of central and peripheral neural control mechanisms evokes a decrease in parasympathetic activity and an increase sympathetic activity to...
