Background Information Following research on physical performance, I came up with the hypothesis that males tend to perform better than females at physical activities because they have better strength, vital capacity and resting pulse rate. Vital capacity: is the volume of air that can be breathed from the lungs after a complete respiration. The vital capacity is usually 3-6 litres, varying with age gender and height. Average male V.C = 4700ml Average female V.C = 3400ml Males have a better vital capacity because they have a bigger surface area in their lungs which means they can inhale and exhale a large amount of air. Activities such as swimming will increases ones vital capacity while smoking, asthma alters it. Research has shown that the capacity of a person’s lungs is proportional to the surface area of his or her body. This means that the males will have a bigger surface area than girls. The formula ‘Surface Area (m2) = square root (kg*cm/3600)’ is used to measure the surface area of one’s body. I will use this to prove my hypothesis later in the experiment. Strength is the ability to exert a force against a resistance. The strength needed for a sprinter to explode from the blocks is different to the strength needed by a weight lifter to lift a 200kg bar-bell. This therefore implies that there are different types of strength. Males achieve better performance times at strength activities because they relatively engage in a perfectly legal, natural form of blood doping The Key sex hormone testosterone increases the production of hemoglobin.
