Summary of changes in psychosocial variables over time between R-HIIT (n = 7) and MM-HIIT (n = 9) groups from ANCOVA.
| Outcome and group | Baseline (unadjusted means) | Postintervention (unadjusted means) | Postintervention (adjusted means) | Adjusted mean difference (95% CI) | Effect size (partial eta squared) | P value |
|---|---|---|---|---|---|---|

| MM-HIIT | 63.09 ± 17.88 | 66.67 ± 13.57 | 67.22 ± 12.17 | 6.75 (−6.52 to 20.02) | 0.09 | 0.292 |
| R-HIIT | 65.95 ± 23.42 | 61.19 ± 16.36 | 60.47 ± 12.18 | |||

| Perceived wellness | ||||||
| MM-HIIT | 14.70 ± 2.89 | 16.73 ± 3.08 | 16.75 ± 2.31 | −0.335 (−2.852 to 2.182) | 0.006 | 0.778 |

Plus-minus values are means ± SD with postintervention means being adjusted for covariates of baseline values, and data in parentheses are 95% CI. Mean difference is based on rowing group minus multimodal group after the intervention. MM-HIIT = multimodal high-intensity interval training; R-HIIT = rowing high-intensity interval training.
