Following the warm-up, the single-leg drop landing (SLDL) task will be clearly explained and demonstrated to all participants.Stand barefoot on both legs on a 30 cm box, then extend the testing leg forward. They will then step off the box using the testing leg, land on the same leg with a toe-heel landing pattern. After familiarization, participants will perform three trials of the SLDL task under non-fatigued conditions.Following the completion of the non-fatigue single-leg drop landing (SLDL) trials, each participant will perform three maximal vertical jumps to assess their maximum touch height. The highest value obtained from these attempts will be recorded as the participant's baseline for subsequent comparisons.Following the completion of the baseline maximal vertical jump assessment, participants will undergo a systematic fatigue induction protocol",[9],null,[20],{"name":21,"role":22,"phone":23,"phoneExt":18,"email":24},"mawada mohamed, master","CONTACT","+20 10 24330410","mawada.mooda96@gmail.com",{"type":26,"investigatorFullName":27,"investigatorTitle":28,"investigatorAffiliation":5,"oldNameTitle":18,"oldOrganization":18},"PRINCIPAL_INVESTIGATOR","Mawada Mohamed Meshref Ibrahim","principle investigator :mowada mohamed meshref","100642465","the-effect-of-muscular-fatigue-on-lower-limb-kinematics-during-single-leg-drop-landing-in-female-athletes-100642465",false,"NCT07648537","The Effect of Muscular Fatigue on Lower Limb Kinematics During Single-Leg Drop Landing in Female Athletes","SLD","Inclusion Criteria:\n\n* Female volleyball players aged 20-25 years\n* Practice professional volleyball training or competition experience of at least 2 years\n* typically engage in a high volume of training, with regular participation in at least five training sessions per week\n* Willingness to adhere to fatigue protocol and provide informed consent\n\nExclusion Criteria:\n\n* Current or recent (within the past 6 months) lower limb injury or medical condition\n* History of lower limb surgeries\n* Neurological disorders or balance impairments .\n* Experiencing pain or discomfort during jumping or landing tasks\n* Body mass index (BMI) greater than 30 kg\u002Fm²\n* Inability to comply with the fatigue protocol or follow instructions for the landing tasks",true,"FEMALE","20 Years","25 Years",{"count":41,"type":42},35,"ESTIMATED","INTERVENTIONAL",[45],"NA","this study will be conducted to investigate the effect of muscular fatigue on lower limb kinematics during single-leg drop landing in female professional volleyball players using a mobile-based motion analysis application.",[48],"Athletes",[50,51,52,53],"Muscular Fatigue","Lower Limb Kinematics","Single-Leg Drop Landing","Female Athletes","NOT_YET_RECRUITING","2026-06-10",{"date":57,"type":58},"2026-06-15","ACTUAL",{"date":60,"type":42},"2026-06-30",{"date":62,"type":42},"2026-12-20",{"name":5,"class":6}]
