Abstract Details: Background: The strength of the abdominal and dorsal extension muscles are part of the region known as the Core and acts to stabilize the body. In basketball, at different times there are intense unilateral jumps such as layups and the Cross Hop Test can simulate this type of activity and serves to assess the athlete's ability to perform this type of play. Considering the existence of contact in basketball and the demand for unilateral jumps, stabilization of the body is necessary, which underlies the need to evaluate Core strength and vigorous unilateral jumps. PURPOSE: To correlate abdominal strength, dorsal extension strength and performance in the cross hop test in adult professional basketball players. METHODS: Original, descriptive correlational research, which had 9 participants . Data were collected only during one visit to the training center, with the dorsal extension isometric strength test being carried out, with a Crown Dsal-200kgf dorsal dynamometer, instructed to produce maximum isometric dorsal extension strength for 5 seconds in 3 attempts with an interval of 2 minutes, the highest value recorded. After that, Crossover Hop Test Right Side and Crossover Hop Test left Side were carried out, with adhesive tape fixed to the ground measuring 6 cm long and 15 cm wide and two perpendicular tapes at the start and end point of the test. 3 jumps were performed, taking the longest distance. Finally, the 1-minute abdominal resistance test was performed, which consisted of performing the maximum number of trunk flexion repetitions in 1 minute. RESULTS: Abdominal strength 48.78±4.66 (repetitions) P-value 0.66; isometric dorsal extension strength 162.44±17.22 (kgf) P-value 0.64; Cross Hop Test Right Side 6.45±0.34 (m) P-value 0.39; Cross Hop Test Left Side 636±0.44 (m) P-value 0.47. The T test for paired samples data determined that there was no significant difference between the results of the Cross-Over Hop Test with p=0.199. Pearson's correlation test found a very strong positive correlation only between the right and expected Cross-Over Hop Test r=0.915 and p=0.001, a consistent result considering that no significant difference was found between the sides, demonstrating that the athletes are symmetrical in terms of the power of the lower limbs. CONCLUSIONS: It is possible to conclude that the strength of the abdominal and dorsal extension muscles are not associated in the performance of the Cross Hop Test jumps and that the athletes are symmetrical between the power of the right and left lower limbs. PRACTICAL APPLICATIONS: the study has practical application considering that it evaluates symmetry between power between the lower limbs which is related to performance and injury. The strength of the abdominal and dorsal extension muscles must be constantly assessed, regardless of whether or not they correlate with jumping performance, as they are indicators of the body's stability. The power of the lower limbs can also be used to control training load.
