Competitive sports demand peak psychophysiological performance and basketball is no exception. This study investigates the effects of Progressive Muscle Relaxation (PMR) as an intervention to enhance the psychophysiological well-being of basketball athletes. PMR, a wellestablished relaxation technique, has shown promise in reducing stress and enhancing overall performance. In this research, a group of basketball athletes participated in a structured PMR program while a control group followed regular training routines. Various psychophysiological variables, including stress levels, heart rate variability and perceived performance, were assessed before and after the intervention.

The findings reveal that the implementation of PMR resulted in significant reductions in stress levels and improvements in heart rate variability among the basketball athletes. Additionally, athletes in the PMR group reported enhanced perceived performance compared to the control group. These results underscore the potential of PMR as a valuable tool in the psychophysiological optimization of basketball athletes, with implications for stress management, recovery and overall athletic performance. PMR could be integrated into training regimens to promote mental and physical well-being among basketball athletes, ultimately enhancing their competitive edge on the court.

This study investigates the dietary patterns and supplement utilization among competitive female bodybuilders. Dietary intake plays a pivotal role in achieving peak performance and the desired physique in bodybuilding competitions. Through a comprehensive analysis, this research explores the nutritional strategies, micronutrient supplementation and dietary challenges faced by female bodybuilders in their pursuit of athletic excellence. The findings shed light on the complex interplay between nutrition and competitive bodybuilding, providing insights that can inform personalized dietary recommendations and optimize performance outcomes.

This review explores the phenomenon of cardiac troponin elevation following physical activity in healthy young athletes. Cardiac troponins are highly sensitive markers of myocardial injury traditionally associated with acute cardiac events. However, recent research has demonstrated that intense exercise can also lead to transient elevations in cardiac troponin levels, even in the absence of underlying heart disease. The aim of this review is to provide a comprehensive analysis of the factors contributing to cardiac troponin elevation in young athletes, its clinical significance and implications for sports cardiology practice.

This paper delves into the intricate realm of sports cardiology, specifically focusing on the emerging field of cardiac biomarkers. The study explores the relevance and application of various biomarkers in assessing cardiovascular health among athletes. Through an extensive literature review, we investigate the utilization of biomarkers in the diagnosis, monitoring and risk stratification of cardiac conditions in athletes. This review aims to shed light on the pivotal role of biomarkers in enhancing the early detection and management of cardiovascular issues in sports medicine, ultimately contributing to the holistic well-being of athletes.
