Key result
Protein supplements show no association with cardiovascular parameters or exercise capacity in male athletes.
Why the study?
Arrhythmias are responsible for most sudden cardiac deaths in professional athletes, and performance-enhancing dietary supplements have been implicated in recent years.
Does protein supplementation affect cardiovascular parameters (ECG, heart rate, effort capacity, blood pressure) in male sportsmen?

Does protein supplementation affect cardiovascular parameters (ECG, heart rate, effort capacity, blood pressure) in male sportsmen?
p-value: p=>0.05
Daily use of approximately 40 grams of protein supplements does not significantly alter ECG findings, heart rate, effort capacity, or blood pressure in male athletes.
No adverse ECG or exercise effects seen with ~40 g daily protein supplements in athletes; leaves open arrhythmia risk in larger prospective studies.
Purpose: Arrhythmias are reproached for most of the sudden cardiac deaths in professional athletes. Also, performance-enhancing dietary supplements have been blamed in recent years. In this study, we aimed to investigate the effect of protein supplements (PS) on regular training athletes. Materials and Methods: 70 male sportsmen (30.0 ± 7.3 year) who regularly train in the gym, were included in the study; 35 used approximately 40 grams of PS daily, while the other half regularly trained without additional PS. All participants underwent ECG, exercise test and results were evaluated by two independent cardiologists. Results: There were no differences between two groups in terms of age, smoking and alcohol use, body mass index, baseline ECG results, effort capacity, heart rate, and blood pressure values. Correlation analyses showed a negative correlation between the age and maximum HR in an effort test. Conclusion: This study showed that using PS in certain does not have any effect on ECG findings, heart rate at both rest and during exercise, effort capacity evaluated by a treadmill test, and blood pressure values of sportsmen.

Usalp et al. (2020) conducted a cross-sectional in Healthy male sportsmen (n=70). Protein supplements vs. No protein supplements was evaluated on ECG findings, heart rate, effort capacity, and blood pressure (p=>0.05). Protein supplement consumption had no significant effect on ECG findings, resting or exercise heart rate, effort capacity, or blood pressure in male sportsmen.
