Study Type:
Interventional
Study Design:
Basic Design - Parallel
Randomization - Randomized
Blinding - Open -no one is blinded
Control - Active
Primary Sponsor:
Institute - Hokkaido Bunkyo University
Condition:
Condition - Healthy adults
Classification by malignancy - Others
Genomic information - NO
Objective:
Narrative objectives1 - This study aims to examine whether internal or external attentional focus instructions during bodyweight squat practice induce immediate changes in impact absorption strategies during drop landing, shifting from a knee-dominant strategy toward a hip-dominant strategy, in healthy adults.
Basic objectives2 - Efficacy
Intervention:
Interventions/Control_1 - Participants perform bodyweight squat practice once on the same day between pre intervention and post intervention assessments The practice consists of 3 sets of 10 repetitions with 60 seconds rest between sets Posture conditions and movement tempo are standardized to match the assessment task Attentional focus instructions are provided only during the descending phase of the squat Participants in the internal focus group are instructed to take 2 seconds to lower the body by flexing the hips and moving the buttocks backward The instruction is provided once before each set and one brief reminder is provided during each set If participants report pain or physical discomfort the exercise is stopped immediately and the session is paused or discontinued as necessary
Interventions/Control_2 - Participants perform bodyweight squat practice once on the same day between pre intervention and post intervention assessments The practice consists of 3 sets of 10 repetitions with 60 seconds rest between sets Posture conditions and movement tempo are standardized to match the assessment task Attentional focus instructions are provided only during the descending phase of the squat In the external focus group a box is placed behind the participant at a height that allows the buttocks to contact the box when the thighs are parallel to the floor Participants are instructed to take 2 seconds to lower the body toward the box behind them and lightly touch it The instruction is provided once before each set and one brief reminder is provided during each set If participants report pain or physical discomfort the exercise is stopped immediately and the session is paused or discontinued as necessary
