| Height (cm) | 154.6 (7.5) | 152.8 (7.8) | 154.3 (6.9) | 157.4 (7.2)*a |
| Weight (kg) | 44.1 (8.6) | 43.1 (7.7) | 43.6 (8.5) | 46.3 (9.6) |
| BMI | 18.4 (2.4) | 18.5 (2.2) | 18.2 (2.6) | 18.5 (2.5) |
| HR exercise (beats/min) | 120.1 (12.5) | 127.0 (12.6)*cs | 114.1 (10.6) | 119.7 (9.9)*ac |
| %HR max | 57.7 (6.0) | 60.9 (6.0)*cs | 54.8 (5.1) | 57.6 (4.8)*ac |
| Moderate-to-vigorous zone (% of core 10 min) | 24.4 (24.8) | 39.5 (27.0)*cs | 14.1 (17.3) | 18.8 (20.9) |
| Familiarization day LDST | 47.2 (8.9) | 45.2 (8.7) | 46.8 (8.5) | 50.6 (8.8) |
| Baseline LDST | 49.2 (8.7) | 47.7 (8.7) | 49.5 (8.8) | 51.1 (8.5) |
| Familiarization day d2 | 142.1 (22.5) | 141.3 (24.2) | 139.8 (20.4) | 146.5 (22.8) |
| Baseline d2 | 166.5 (26.0) | 163.6 (26.3) | 165.1 (25.2) | 172.7 (26.2) |
| Perceived fun of exercise | 3.9 (0.9) | 3.6 (0.9) | 4.0 (0.9) | 3.9 (0.7) |
| Perceived difficulty of exercise | 1.9 (1.0) | 1.6 (0.8) | 2.2 (1.1) | 1.8 (0.9) |
Baseline LDST and d2 scores are pre-test scores at the first experimental day. ∗a, significantly different from aerobic group (p < 0.05); ∗ac, significantly different from aerobic and coordination group (p < 0.05 and p < 0.001); ∗cs, significantly different from coordination and strength group (p < 0.001 and p < 0.05).
