Abstract

Physical training and fitness are important aspects in an athlete's readiness to achieve optimal performance in their sport. One important indicator of fitness is vital lung capacity, which measures the maximum amount of air that can be moved into and out of the lungs. The aim of this study was to investigate the optimization of vital lung capacity as a strategy to improve athlete fitness. This study used qualitative research methods. The data collection technique in this research is literature study. The data that has been collected is then analyzed in three stages, namely data reduction, data presentation and drawing conclusions. The research results show that optimizing lung capacity to improve athlete fitness can be done through several methods, including breathing exercises, physical training and aerobic training. Increasing vital lung capacity can also help minimize the risk of injury, as a stronger respiratory system is able to prevent excessive fatigue. Overall, this can have a positive impact on athletes' achievements, both at national, regional and international levels, as well as representing the country, region or institution they are fighting for.

Abstract

In 2019, the coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome corona virus 2 (SARS-CoV-2), has killed more than 6.6 millions of people around the world as of end of 2022. The long-term impact of COVID-19 is persisted, including its impact on male reproduction. SARS-CoV-2 enters into host cells using the angiotensin-converting enzyme 2 (ACE2) and transmembrane serine protease 2 (TMPRSS2) receptors. Both of these receptors are expressed more in men, and therefore men are more susceptible to SARS-CoV-2. COVID-19 potentially cause infertility by damaging testicular tissues and interfering with the process of spermatogenesis. A decrease in serum levels of testosterone, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) as well as a decrease in sperm quality in men with COVID-19 compared to healthy men of the same age has been reported in several studies. Utilizing existing research data, this study aims to explore in detail of how SARS-CoV-2 tends to affect male fertility.
