    Abstract: Reaction time is a measure of how quickly an organism can respond to a particular stimulus. In sports, the reaction time is the ability to respond quickly with proper posture and control to a stimulus such as sound or light. Choice reaction time has multiple stimuli and multiple responses and reaction must correspond to the correct stimulus. Purpos... Show More

    Abstract: Unstable surfaces have been used in resistance training, but there are no studies that compared energy cost between stable and unstable surfaces in circuit weight training. This study compared energy cost, post-exercise peak blood lactate and perceived exertion rate between stable surface and unstable surface. Twenty healthy men (24.65 ± 3.48 years... Show More

    Abstract: Collegiate golf is physically demanding; however, little research has been done to establish the energy expenditure (EE) and metabolic demand on a golfer during competition. With advances in wearable technology, it has become easier to gain knowledge on physical activities outside the lab. Therefore, the purpose of this study was to determine the a... Show More

    Abstract: Indiscriminate use of anabolic steroids is associated with cardiovascular diseases, such as myocardial infarction, thrombosis, and arterial obstruction. Furthermore, high levels of androgens increase hepatic toxicity and the risk of cancer. Contrastingly, green tea prevents and controls cardiovascular and hepatic diseases, as it can improve the lip... Show More

    Abstract: Chronic Kidney Disease (CKD) patients are inactive and have reduced physical performance. The CKD lead to abnormalities in various systems including the hemostatic and oxidative systems. The platelet activation occurs with the participation of adenine nucleotides such as ATP and ADP. This nucleotides are part of a system calls purinergic signaling,... Show More
