The demands on a football player during a game or training can be determined from match/training analysis and physiological measurements during match play. Many factors influence the demands of a player, such as the players physical capacity, playing position, style of playing and even how much possession a team has during a game.
Track cycling events range from a 200m flying sprint (lasting ∼10 seconds) to the 50km points race (lasting ∼1 hour). The shorter sprint track events require the cyclist to utilise both the aerobic and anaerobic metabolic pathways. For sprint cyclists fast-twitch muscle fibers will make up the bulk of their muscle mass.
