The Action of the Energy Drink on the Recovery Heart Rate is Independent of the Functional Capacity

Rodrigo Freire Dutra et al. Francisco Eberth Marinho Marques Luciana Diniz Nagem Janot de Matos

The consumption of caffeinated energy drinks (ED) has increased considerably in recent years. Increased ability to concentrate, gain in work performance and increased performance in physical activity are some of the reasons that lead to the search for the drink.

During the pandemic, with changes in routine imposed by the need for social isolation, some works reported an increase in ED intake. There was also greater consumption in the young population motivated by factors such as better performance in sports and the ability to concentrate.^,

Acute Effects of Energy Drink on Autonomic and Cardiovascular Parameters Recovery in Individuals with Different Cardiorespiratory Fitness: A Randomized, Crossover, Double-Blind and Placebo-Controlled Trial

Andrey Alves Porto et al. Luana Almeida Gonzaga Cicero Jonas R Benjamim Carlos Roberto Bueno Jr … David M. Garner Luiz C.M Vanderlei Celso Ferreira Vitor Engrácia Valenti

Abstract

Background

It has been suggested that the consumption of energy drinks (ED) may affect cardiovascular activity.

Objectives

to investigate the acute effects of ED intake on heart rate variability (HRV) and cardiovascular recovery after moderate aerobic exercise in males with different cardiorespiratory capacities.

Methods

This is a randomized, double-blind, crossover, placebo-controlled study. Twenty-eight young adults were split into two groups according to their peak oxygen consumption (VO2peak) values: (1) High VO2 peak (HO) – VO2 peak > 52.15 mL/kg/min, and (2) low VO2 peak (LO) – peak VO2 <52.15 mL/kg/min. Subjects of both groups underwent two exercise protocols in randomized order: moderate aerobic exercise (60% of VO2peak) following the intake of 250 mL of water (placebo protocol) or 250 mL of ED (ED protocol). During the exercise tests, values of cardiorespiratory and HRV parameters were recorded.

Results

Significant differences were observed for the LF (normalized units) index between rest and Rec1 in HO energy and LO groups during the ED protocol. For the LF/HF ratio, significant differences were seen between rest and Rec1 in HO and LO during ED protocols.

Conclusion

Acute ED intake delayed heart rate recovery after exercise in subjects with low and high cardiorespiratory fitness.

Inter-Individual Responses to Citrulline Malate Oral Supplementation on Post-Exercise Hypotension in Hypertensives: A 24-Hour Analysis

Juliano Casonatto et al. Daniel Massaharu Enokida Kamila Grandolfi

Abstract

Background:

Studies have persuasively demonstrated that citrulline has a key role in the arginine-nitric oxide system, increasing nitric oxide bioavailability, an important mediator of peripheral vasodilation.

Objective:

To analyze the inter-individual post-exercise hypotension responsiveness following acute citrulline supplementation in hypertensives.

Methods:

Forty hypertensives were randomly assigned to one of the four experimental groups (control-placebo, control-citrulline, exercise-placebo, and exercise-citrulline). They ingested placebo or citrulline malate [CM] (6 grams). During the exercise session, individuals performed 40 minutes of walking/running on a treadmill at 60-70% of HR reserve. For the control session, the individuals remained seated at rest for 40 minutes. Office blood pressure (BP) was taken every 10 minutes until completing 60 minutes after the experimental session. The ambulatory BP device was programmed to take the readings every 20 minutes (awake time) and every 30 minutes (sleep time) over the course of 24 hours of monitoring. Statistical significance was defined as p < 0.05.

Results:

Unlike the other experimental groups, there were no “non-responders” in the exercise/citrulline (EC) for “awake” (systolic and diastolic BP) and “24 hours” (diastolic BP). The effect sizes were more consistent in the EC for systolic and diastolic ambulatorial BP response. The effects were “large” (> 0.8) for “awake”, “asleep”, and “24 hours” only in the EC for diastolic BP.

Conclusion:

CM supplementation can increase the post-exercise hypotensive effects in hypertensives. In addition, the prevalence of non-responders is lower when associated with aerobic exercise and CM supplementation.
