Abstract

The reproduction and the application of the tests carried out during 30 seconds at the following maximum intensity was studied: 1) sit-up with knees bent at 90°, 2) bend overs and 3) body rotations. This was done 3 times with 23 tennis players between 14 and 16 years of age (15 women and 8 men) calculating a) methodical error (ME); b) coefficient of variation (V) associated to ME; c) coefficient of intraclass correlation (ICC); and d) r of Pearson. Conclusions: 1) the sex had no significant effect in any of the 3 tests; 2) the bend overs are the best test to evaluate or develop abdominal strength/resistance; 3) the evaluation via sit up or bend over tests need a prior run through; 4) the bend overs (ICC=0.97) and sit-up (ICC=0.95) were highly reproductable and with V lower among the different applications; 5) the evaluation of the body rotations need another alternative test.
