|---|---|
| 1. Muscle activity measured using textile EMG shorts throughout the 8.5-h intervention 2. Heart rate measured using a heart rate belt throughout the 8.5-h intervention 3. Physical activity measured using accelerometry 2 days before each condition 4. Food intake measured using self-reported dialogue 2 days before each condition 5. Blood pressure measured using an electronic blood pressure monitor every 45 minutes during the measurement (beginning, 1:00, 1:45, 2:30, 3:15, 4:00, 4:45, 5:30, 6:15, 7:00, 7:45, and 8:30 of the experiment time) 6. Perceived feelings, including shoulder, upper limbs, waist, hip, and lower limbs discomfort, fatigue, and working efficiency, measured using a visual analogue scale every 45 minutes during the measurement (beginning, 1:00, 1:45, 2:30, 3:15, 4:00, 4:45, 5:30, 6:15, 7:00, 7:45, and 8:30 of the experiment time) 7.
