The physical demands of tournament tennis players can be and usually are very exhausting. The body uses both anaerobic and aerobic metabolism as well as anaerobic and aerobic muscle fiber types. Tennis is a high-intensity sport that requires hundreds of short bursts of activity. Most points only last about 10 seconds (anaerobic), but there is only 25 seconds of rest between points and 90 seconds of rest between matches, requiring the player to demonstrate endurance ( aerobic). Tennis matches can be long and drawn out, lasting for hours, or they can be fast, intense and only last an hour. This means that proper nutrition as well as an efficient metabolism are essential to being able to compete at the highest level. Ferrauti et al conducted a study on high-level tennis players. Their study aimed to observe how blood sugar fluctuated over the course of several tournaments and practice matches, as well as to check how many of these tennis players suffered from hypoglycemia because they were playing too much and not getting adequate nutrition to maintain their blood sugar. balance. Ferrauti et al surveyed 147 tournament tennis players. Their goal was to find out how many of these athletes had symptoms of hypoglycemia. Of the 147 male tennis players, 94 confirmed they had hypoglycemic symptoms. This means that more than half of the players saw their blood sugar levels drop. This study allowed players to play one singles and one doubles match under tournament and practice conditions. Tissue glucose consumption and glucose production are balanced when the body is at rest. At the beginning of exercise, the energy that the body obtains quickly comes from anaerobic metabolism using mainly muscle glycogen ... middle of paper ...... should be around 0.5 to 0.8 gram of protein per pound per day. Balancing a tennis player's fluid intake is also essential. Too much fluid can weigh the athlete down and too little can dehydrate them. Two glasses of water two hours before a match are recommended. During a game, keep 5 to 10 ounces of sports drink in your bag and drink at each change. After a match, replace lost water. Drink as much fluid as needed until your thirst is quenched. Having and using this knowledge can be very beneficial to a tennis player's performance on court, especially during the latter stages of a tournament.
