|---|---|---|---|
| Primary | Perceived Lower-Extremity Muscle Soreness Score | Pre-exercise, immediately post-exercise, and 6, 24, 48, and 72 hours after each HIIT session | Perceived lower-extremity muscle soreness was assessed using a 0-10 visual analogue scale (VAS), where 0 indicated no soreness and 10 indicated extreme soreness. The unit of measure was the VAS score (0-10). Assessments were performed at each specified time point following both HIIT sessions. This outcome is designated as the primary outcome for registry purposes in this retrospective registration; no single primary outcome was pre-specified in the original study protocol. |

The unit of measure was U/L. |
| Secondary | Serum Lactate Dehydrogenase Concentration | Pre-exercise, immediately post-exercise, and 6, 24, 48, and 72 hours after each HIIT session | Serum lactate dehydrogenase (LDH) concentration was measured as an indirect circulating marker associated with exercise-related tissue and muscle stress. The unit of measure was U/L. |
| Secondary | Serum Alanine Aminotransferase Concentration | Pre-exercise, immediately post-exercise, and 6, 24, 48, and 72 hours after each HIIT session | Serum alanine aminotransferase (ALT) concentration was measured as a non-specific circulating aminotransferase associated with exercise-related tissue stress. The unit of measure was U/L. |
| Secondary | Serum Aspartate Aminotransferase Concentration | Pre-exercise, immediately post-exercise, and 6, 24, 48, and 72 hours after each HIIT session | Serum aspartate aminotransferase (AST) concentration was measured as a non-specific circulating aminotransferase associated with exercise-related tissue stress. The unit of measure was U/L. |
| Secondary | Serum C-Reactive Protein Concentration | Pre-exercise, immediately post-exercise, and 6, 24, 48, and 72 hours after each HIIT session | Serum C-reactive protein (CRP) concentration was measured as an inflammatory biomarker. The unit of measure was mg/L. |
| Secondary | Serum Creatine Kinase-MB Concentration | Pre-exercise, immediately post-exercise, and 6, 24, 48, and 72 hours after each HIIT session | Serum creatine kinase-MB (CK-MB) concentration was measured as an exploratory, non-specific index of exercise-related tissue stress. The unit of measure was ng/mL. |
| Secondary | Serum Heart-Type Fatty Acid-Binding Protein Concentration | Pre-exercise, immediately post-exercise, and 6, 24, 48, and 72 hours after each HIIT session | Serum heart-type fatty acid-binding protein (H-FABP) concentration was measured as an exploratory, non-specific index of exercise-related tissue stress. The unit of measure was ng/mL. |
| Secondary | Countermovement Jump Height | Pre-exercise, immediately post-exercise, and 6, 24, 48, and 72 hours after each HIIT session | Countermovement jump (CMJ) height was assessed as an indicator of lower-body neuromuscular performance and recovery. The unit of measure was cm. |
| Secondary | Countermovement Jump Power | Pre-exercise, immediately post-exercise, and 6, 24, 48, and 72 hours after each HIIT session | Countermovement jump (CMJ) power was assessed as an indicator of lower-body neuromuscular performance and recovery. The unit of measure was kW. |
| Secondary | Countermovement Jump Mean Velocity | Pre-exercise, immediately post-exercise, and 6, 24, 48, and 72 hours after each HIIT session | Countermovement jump (CMJ) mean velocity was assessed as an indicator of lower-body neuromuscular performance and recovery. The unit of measure was m/s. |
| Secondary | Countermovement Jump Flight Time | Pre-exercise, immediately post-exercise, and 6, 24, 48, and 72 hours after each HIIT session | Countermovement jump (CMJ) flight time was assessed as an indicator of lower-body neuromuscular performance and recovery. The unit of measure was ms. |
| Secondary | Whole-Blood Valine Concentration | Pre-exercise, immediately post-exercise, and 6, 24, 48, and 72 hours after each HIIT session | Whole-blood valine concentration was quantified using targeted liquid chromatography-tandem mass spectrometry (LC-MS/MS) from capillary blood collected by volumetric absorptive microsampling (VAMS). The unit of measure was µmol/L. |
| Secondary | Whole-Blood Phenylalanine Concentration | Pre-exercise, immediately post-exercise, and 6, 24, 48, and 72 hours after each HIIT session | Whole-blood phenylalanine concentration was quantified using targeted LC-MS/MS from capillary blood collected by VAMS.
