The differences in the male and female body involve more than just physical appearance such as height and weight; they also involve physical ability. While there are outliers, the average man has advantages over the average women in areas such as cardiovascular endurance, the ability to decompose fat and build muscle.

Muscle Growth

When men and women undergo the same type of intensive training, men typically gain more muscle size. The reason for this disparity has to do with the ratio of Type I and Type II muscle fibres. Women have an equal amount of Type I and Type II fibres, while men have a disproportionate amount of Type II fibres. Type II fibres are the fast-twitch fibres that are used for power, whereas Type I muscle fibres are slow twitch and used for aerobic purposes. This fact prevents women from experiencing the same muscle growth as men even when performing the same workout.

Fat Storage and Decomposition

Men have a lower body fat percentage than women. A healthy range for men is 10 to 15 per cent, whereas women hover between 20 and 25 per cent body fat. When the body accumulates excess fat, male bodies store it in their abdominal region while women store it in their hip area.

The simple distribution of fat gives men an advantage with mobilising and decomposing it. According to researchers Chantal Vella and Len Kravitz, in a 2002 study, fat that is stored in the abdominal region is more open to epinephrine stimulation than fat in the hip area. Men have additional advantage in that their resting metabolism is higher than that of women.

Lung and Heart Capacity

Men have been shown to have a better beginning level VO2 max, which is the maximum amount of oxygen the body can take in during maximum effort. The average untrained male will have a resting VO2 max of 3.5 litres per minute, while an untrained female will have at 2.0 litres per minute. This differential is due in part to the physical size disparities between men and women as well as women having a higher body fat percentage. With regards to the body's ability to deliver oxygen, women have a lower blood haemoglobin level than men which can impact oxygen delivery to the body.

Muscular Strength and Power

Due to the higher number of Type II muscle fibres, lower body fat percentage and greater VO2 max, men have greater muscular strength and power. Because of the increased Type II fibres, men have greater muscle mass, especially in the upper body, which is the source of their greater strength. The advantages in power come from the muscle fibres and VO2 measurements. On the average, men have significantly greater amounts of peak power and overall power when adjusted for body weight.
