Contractions Connor Howe 31451131 HMKN 310 UBC Okanagan Greg duManoir October 18, 2015 Introduction Muscle fatigue is the result of a series of structural, metabolic and energetic changes in muscle fibers caused by changes in nervous system efficiency as well as decreased oxygen and nutrient supply (Cifrek, Medved, Tonković, & Ostojić, 2009). A major driving force behind muscle fatigue is lactate buildup. As lactate builds up there is a shift in intracellular pH levels which causes a…

Maximal Oxygen Consumption; also known as VO2max, is defined as the highest rate at which oxygen can be taken in and used by the body every minute during intense exercise (2). It is measured in mL/kg/min, defined as the milliliters of oxygen per kilogram of body mass per minute. VO2max is generally measured by using a maximal exercise test to physical voluntary exhaustion where speed or power are increased consistently, requiring more oxygen uptake each phase. (1) Exercise intensities are…

categories 1) Utilization and 2) Delivery. Utilization is being able to extract and use oxygen. Delivery is about the transportation of oxygen cells either through the CVD or pulmonary system. VO2 is important for exercise and transporting oxygen to the muscles. VO2 max is important to health because it gives information on the function cardiac output of the heart, and the arterial-venous oxygen difference. In addition, it is used in making ATP, which is used for energy. Energy is used for your…
