Background: A “Soy Protein Isolate enriched Pregame Chocolate Bar” (SPIPCB) developed was evaluated for its acceptability, nutrient content, keeping quality and its effect on selected male athletes.

Materials and Methods: 100 g of the soy protein enriched bar was administered to the athletes as a pregame meal. 75 sprinters were selected from the District Sports Hostel, Tirunelveli and were equally distributed into 3 groups of 25 each. The first group (Group I) was used to study on a cross sectional basis. All of them were subjected to performance assessment before (on empty stomach) and after they were given the two pregame meals. Bread and Jam (UPGM) was chosen as the pregame meal for comparison purpose. Subsequently after an interval of seven days, the enriched SPIPCB-I was given once on a chosen day. After an interval of 7 days the SPIPCB -7 was given for 7 consecutive days and performance evaluated on the seventh day. The second (UGPM- Group II) and third (SPIPCB -Group III) groups of 25 each were also subjected to impact evaluation. It was a onetime provision and performance was assessed using physical work capacity (Harvard Step Test), Endurance Test (Tread mill Test), Athletic event test (100 m sprint).
