Health and Physical Education - XI So considering all such things we can say that ‘endurance is the physiological as well as psychological ability of an individual to do some specific type of work for longer duration with the desired quality under the condition of fatigue’. Endurance can be divided into three types, as far as nature of the activity is concerned. . Basic endurance: This type of endurance ability makes an individual capable to carry out any type of work for longer duration. It is not task specific. This type of endurance largely depends upon aerobic capacity of an individual. In this type of endurance, the pace of the activity is slow. . General endurance: This type of endurance ability makes an individual capable to carry out any type of work for longer duration with various movement patterns and pace. The nature of the pace may change according to the demand of the activity. . Specific endurance: This type of endurance ability makes an individual capable to carry out a specific type of work for longer duration with a set type of movement patterns and pace. This involves aerobic as well as anaerobic qualities of an individual and is highly trainable in nature. Factors determining endurance Various physiological and psychological factors are involved in determining the endurance of an individual. These factors are muscle fibre type, aerobic capacity, anaerobic capacity, movement pattern and psychological factors. . Muscle fibre type: Muscles are made up of two types of fibres, namely fast twitch and slow twitch fibre. Both types are present in the muscle of an individual. If the ratio of slow twitch fibres is more, then an individual will possess the aerobic capacity which will enable him/her to have endurance ability. In the same manner, if there is higher ratio of fast twitch fibres, then an individual will possess the anaerobic capacity and will dominate in strength and speed activities. . Aerobic Capacity: It is the ability of muscle to utilise more amount of oxygen while working. This type of capacity largely depends upon the oxygen uptake, its transportation from atmosphere to the working muscles and oxygen consumption. Oxygen intake is the amount of oxygen which is -
