Risk of injury analysis in depth jump and squat jump

Introduction: The depth jump (DJ) and squat (SJ) are accepted ways to assess train power producing ability but not without risk of injury. Methods: Sixteen male participants (age = 21.7 ± 1.54 yrs., height 177.7 11.4 cm, mass 77.7 13.6 kg) were evaluated for exertion capabilities while being assessed injury in the knee low back through a range resistances based on percentage participants’ heights DJ (0% 50%) bodyweights SJ 100%). Two variables used knee: valgus angle internal abduction moment (IAM). Four back: compression shear force at L5/S1 vertebrae, intra-abdominal pressure (IAP), erector muscle tension. Results: With increasing drop height, showed increased IAM. In back, significant correlation occurred between IAP tension more correlated with than height. resistance, no was detected. However, all except significantly influenced by resistance. Conclusion: Risk can be strongly dependent only type jump, also amount resulting exerted athlete influence
