Inclusion criteria

Inclusion criteria: - Healthy adults aged 18 to 30 years - No history of musculoskeletal disease and no upper limb injury within the past year - No current or previous history of central nervous system disease, sleep disorder, or psychiatric disorder (screened by interview/questionnaires) - Able to provide written informed consent and comply with the study procedures including sleep schedule control

Exclusion criteria

Design outcomes

Primary

MeasureTime frame
Motor skill retention rate on day 2: retention rate (%) calculated from day-2 performance (RMSE) relative to the day-1 post-test—

Secondary

MeasureTime frame
1) Motor skill retention rate on day 7 2) Actigraphy-derived sleep parameters over 2 weeks (bedtime, wake-up time, TRT, TST, REM, non-REM, WASO, sleep efficiency) 3) Subjective sleep measures (PSQI-J, JESS)—
