Effects of task-specific augmented feedback on deficit modification during performance of the tuck-jump exercise.
CONTEXT Anterior cruciate ligament ( ACL ) injuries are prevalent in female athletes . Specific factors have possible links to increasing a female athlete 's chances of suffering an ACL injury . However , it is unclear if augmented feedback may be able to decrease possible risk factors . OBJECTIVE To compare the effects of task-specific feedback on a repeated tuck-jump maneuver . DESIGN Double-blind r and omized controlled trial . SETTING Sports-medicine biodynamics center . PATIENTS 37 female subjects ( 14.7 ± 1.5 y , 160.9 ± 6.8 cm , 54.5 ± 7.2 kg ) . INTERVENTION All athletes received st and ard off-season training consisting of strength training , plyometrics , and conditioning . They were also videotaped during each session while running on a treadmill at a st and ardized speed ( 8 miles/h ) and while performing a repeated tuck-jump maneuver for 10 s. The augmented feedback group ( AF ) received feedback on deficiencies present in a 10-s tuck jump , while the control group ( CTRL ) received feedback on 10-s treadmill running . MAIN OUTCOME MEASURES Outcome measurements of tuck-jump deficits were scored by a blinded rater to determine the effects of group ( CTRL vs AF ) and time ( pre- vs posttesting ) on changes in measured deficits . RESULTS A significant interaction of time by group was noted with the task-specific feedback training ( P = .03 ) . The AF group reduced deficits measured during the tuck-jump assessment by 23.6 % , while the CTRL training reduced deficits by 10.6 % . CONCLUSIONS The results of the current study indicate that task-specific feedback is effective for reducing biomechanical risk factors associated with ACL injury . The data also indicate that specific components of the tuck-jump assessment are potentially more modifiable than others
