Physical and physiological demand of soccer player based on scientific research

Soccer is the most popular sport in the world with nearly 200 million practitioners. Match analysis of the physical demand have revealed that the game is characterized by the mix of short-duration sprints, high- intensity running, jumps, duels, tackles, directional changes, backwards, and walking and standing episodes with an average game intensity ranging from 80 to 90% of maximal heart rate (HRmax). For instance, top-level players require developing specific physical capacities such as an elevated aerobic power and the ability to perform repeated HIR (including sprinting) with limited rest period, to be able to cope with the game demands. The utilization of glycogen stores during a football match was suggested to be 155 – 160 g from the muscle glycogen stores, with an estimated 600 kcal of energy provided, while blood glucose derived from the liver may account for approximately 210 kcal of energy during the game. In accordance, the endogenous CHO stores are suggested to supply ~55% of the energy requirements of match-play, and a substantial utilization of lipids and proteins must also be taken into account.
