It is used by athletes in non-endurance sports to promote strength, speed and power and by body builders to build muscle mass. Aerobic means "relating to, involving, or requiring free oxygen", and refers to the use of oxygen to adequately meet energy demands during exercise via aerobic metabolism.Īnaerobic exercise is a physical exercise intense enough to cause lactate to form. Wikipedia describes these training methods as follows:Īerobic exercise (also known as cardio) is physical exercise of low to high intensity that depends primarily on the aerobic energy-generating process. When discussing about any endurance sport and training methods to enhance and improve the components mentioned above, we come across to important training terms aerobic and anaerobic exercises. Fractional utilization – %V0 2max at lactate threshold.The Lactate Threshold / Anaerobic Threshold.However, the majority of a middle/long distance athlete’s training time would be devoted to developing and maximizing their aerobic capacity and efficiency.Īn athlete’s level of ability, as an endurance athlete, will be determined by a number of key physiological components. Energy is also supplied from the anaerobic metabolism of glycogen to form lactate and an initial 4-6 seconds supply comes form the intra-muscular store of high-energy phosphates.ĭespite being small the anaerobic contribution may make a significant contribution to the relative exercise intensity sustained during long events, particularly it comes into play when working hard up a hill, during mid race surges or during a sprint finish. Long events increase aerobic demand as duration increases, and the main aerobic source of energy is through the metabolism of carbohydrates (glycogen) and fats in the form of free fatty acids. The main requirement is the ability to sustain a fast pace over a prolonged period, without sustaining undue fatigue through the build up of lactic acid. An endurance sport is therefore any sport in which there is a prolonged physical stress. So, endurance can be defined as the ability to withstand stress over prolonged periods of time. Training for endurance can reduce the ability to exert endurance strength unless an individual also undertakes resistance training to counteract this effect. It is usually used in aerobic or anaerobic exercise. The definition of 'long' varies according to the type of exertion – minutes for high intensity anaerobic exercise, hours or days for low intensity aerobic exercise. Wikipedia defines the term as such:Įndurance (also related to sufferance, resilience, constitution, fortitude and hardiness) is the ability of an organism to exert itself and remain active for a long period of time, as well as its ability to resist, withstand, recover from, and have immunity to trauma, wounds, or fatigue. But what is endurance in its essence? Let’s define the term and see what really constitutes an endurance sport. Our races usually take a long time to complete and they strain our skiers physically and mentally. Our pro skiers train hard and spend long hours getting into shape. Visma Ski Classics, being the world-class long distance pro skiing tour, is a prime example of a proper endurance sport. Source material by Training 4 Endurance & Wikipedia
