Athletes, Tennis players rather any sport persons needs faster recovery and have to regain their energy level and perform well in their sports competitions.
Many times at National level Athletic championship, I used to run five races in 3 days time period. 800mts: heats(day 1), 800mts:semifinals, finals(day 2), 1500mts:semifinals, finals(day 3).
After each race I was advised by my coach to drink lots of orange juices and to eat bananas which are rich supplement of carbohydrates.
After sports training and workouts, body's stores of glycogen ( carbohydrate that is stored in the muscles and liver) are depleted. If you don't replenish them, your body won't recover properly and your performance will suffer during your next workout or competitions.
Recovery food allows the body to replenish energy stores and repair damaged tissues. Most of the carbohydrates rich food like banana are also rich is sugar which may increase sugar level if your are not a intense long distance runner .
Consuming combination of protein and carbohydrates within 30min after your workouts helps is faster recovery of muscles and to regain glycogen in body.
Soya products are good source of protein with very little fat which is a must for sports person.
