Get Energy Expenditure Of Professional Soccer Players Coelho Form

The lactic acid system is the dominant energy supplier when a midfielder chases down an opponent then immediately runs forward to create attacking movement. In this energy system, glycogen is broken down to release energy and two pryuvic acid molecules are created with the absence of oxygen.

Because of the length of a soccer match, at least 90% of the energy release must be aerobic1; during a 90 minute match, players run about 10 km2,3 at an intensity close to anaerobic threshold or 80–90% of maximal heart rate.

Energy and Movement- Throughout the 90 minutes of a soccer game, energy is supplied by both anaerobic and aerobic energy systems. Each muscle must make its own energy before it can help in movement. To make us move, our muscles have to shorten and pull the bones they attach to into different positions.

Adequate consumption of all macronutrients—carbs, protein and fat—will help you maintain your performance. It's recommended that over the course of a game day, a soccer player's caloric intake should come from 55-65 percent carbohydrates, 12-15 percent protein and less than 30 percent fat.

Eat a carb-rich meal the evening before a match Carbohydrates are the body's preferred source of energy, so it makes sense to give your body what it needs during the hours before a big game. Eating complex carbs helps to build up stores of glycogen, which the body goes to first when it needs fuel.

Energy needs for Soccer At rest almost all energy is provided aerobically using fat as a fuel, but as intensity increases, so does the dependence on anaerobic energy. This is because the anaerobic system can provide energy quickly without needing oxygen.

Results The mean energy expenditure for all players (22±4 years) was 2918±322 kcal. Mean energy intake was 2274±450 kcal, resulting in a discrepancy of ~22%. Carbohydrate intake was below the recommended guidelines on match day at 4.5±1.9 g/kg.

The energy expenditure of a soccer match was estimated as 17.11 ± 1.45 kcal. min-1 or 13.1 ± 1.68 METs, which corresponded to a total average expenditure of 1539.86 ± 130.07 kcal during a complete match.
