Clinical Trial: The Relationship Between Exercise-Induced Clenching and Sleep Bruxism in Continuously Trained and Untrained Individuals: Influence of Exercise Intensity and Temporal Variation (Japan)

Tokyo, Aug. 2 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000058073) titled 'Elucidation of the relationship between exercise-induced clenching and sleep bruxism' on Aug. 1.

Study Type: Interventional

Study Design: Basic Design - Parallel Randomization - Non-randomized Blinding - Open -no one is blinded Control - Active

Primary Sponsor: Institute - Institute of Science Tokyo

Condition: Condition - Exercise-Induced Clenching and Sleep Bruxism Classification by malignancy - Others Genomic information - NO

Objective: Narrative objectives1 - This study aims to compare clenching activity during exercise and the degree of sleep bruxism following low and high-intensity exercise sessions using surface electromyography (EMG). Participants will be divided into two groups: continuously trained and untrained. The masseter muscle activity will be monitored during exercise and sleep across a time course, which will evaluate the expression relationship between sleep and exercise and between-group differences (continuously trained and untrained). Basic objectives2 - Others

Intervention: Interventions/Control_1 - As for low-intensity weightlifting, Participants will perform weightlifting at 40% of 1RM, consisting of 1 set of 30 repetitions followed by 3 sets of 15 repetitions, with 60 seconds of rest between sets.

As for the high-intensity weightlifting, Participants will perform weightlifting at 70% of 1RM, 3 sets followed by 8 repetitions with 1.5 minutes of rest between each set.

1. 45degree Half Squat 2. Bench Press 3. Leg Curl 4. Rowing 5. Unilateral Leg Extension Interventions/Control_2 - As for low-intensity weightlifting, Participants will perform weightlifting at 40% of 1RM, consisting of 1 set of 30 repetitions followed by 3 sets of 15 repetitions, with 60 seconds of rest between sets.

As for the high-intensity weightlifting, Participants will perform weightlifting at 70% of 1RM, 3 sets followed by 8 repetitions with 1.5 minutes of rest between each set.
