1b) Sedentary: < 45 ml/kg/min McArdle, W.D., Katch, F. I., & Katch, V. L. (2006) Untrained: 45 to 50 ml/kg/min McArdle, W.D., Katch, F. I., & Katch, V. L. (2006) Well-Trained: 50 to 60 ml/kg/min McArdle, W.D., Katch, F. I., & Katch, V. L. (2006) Highly Trained: 60-70 ml/kg/min McArdle, W.D., Katch, F. I., & Katch, V. L. (2006) Elite: > 70 ml/kg/min Lucia, A., Hoyos, J., Pérez,M., & Chicharro. (2000) Discussion: The other factors besides VO2 max that may be related to endurance performance include anaerobic threshold, fatigue resistance, economy of motion and fuel usage (McArdle et al., 2006).
1c) Average maximal oxygen consumption for males: 58.46ml/kg/min Standard Deviation for males: 7.0ml/kg/min
Average maximal oxygen consumption for females: 50.2ml/kg/min Standard Deviation for females: 4.7ml/kg/min
2a) The differences in body composition, size, haemoglobin cells, blood volume account for the variance in VO2 max in males and females. Men have more lean muscle mass and respiration occurs at the cellular level of the mitochondria in the muscle, so the more mitochondria means the body can be in a longer state of aerobic respiration (Bonen & Shaw 2008).
2b) V02 max decrease is accompanied by the loss of lean muscle tissue as one ages. According to a study by Betik and Hepple (1988), the reduced rate of muscle oxygen delivery caused by a lowered cardiac output, reduced skeletal muscle oxidative capacity and mitochondrial volume and density, are important factors that cause this decline. It is also important to note that the decline in skeletal muscle oxidative capacity has been noted to decrease by roughly 50% in the older population even under conditions that simulate similar oxygen
