Effects of preexercise carbohydrate ingestion on mountain bike performance

Article Abstract:

A study is done to examine the performance and metabolic effects of consuming 1.0 (LC) and 3.0 (HC) grams of carbohydrate (CHO) per kilogram body mass (BM), 3 h before a 93-min simulated mountain bike race. The data suggested that ingestion of 3.0 g.kg(super -1) BM of CHO 3 h before a 93-min mountain bike simulated race does not produce a statistically significant improvement in overall performance compared with 1.0 g.kg(super -1) BM.

The role of stretching in rehabilitation of hamstring injuries: 80 athletes follow-up

Article Abstract:

The effects of stretching in the rehabilitation of hamstring injuries were assessed. Eighty Greek athletes averaging 20.5 years of age with 'second degree' strain of hamstring muscles were made to do stretching exercises and it was found that stretching reduces muscle stiffness, associated pain and improves overall effectiveness of the rest rehabilitation program.

A randomized trial of preexercise stretching for prevention of lower-limb injury

Article Abstract:

Results point out that preexercise muscle stretching does not produce clinically meanigful reductions in the number of exercise-related injury in army recruits. Data further indicate fitness and age correlate with the prediction of injury risk whereas height, weight, and body mass index do not.
