Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Muscle strength measured using isokinetic dynamometry (Biodex System) at baseline, week 6, and week 18. The specific variables assessed will include peak torque and maximum flexion moment of the hamstrings, and peak torque and maximum extension moment of the quadriceps, along with handgrip strength (using a dynamometer). 2. Physical endurance measured using a submaximal standardized aerobic exercise test on a cycle ergometer (direct measurement of oxygen consumption, VO2 max) at baseline, week 6, and week 18 3. Body composition (muscle and fat mass) measured using bioelectrical impedance (InBody 720) at baseline, week 6, and week 18, alongside anthropometric parameters (height, weight, waist, and hip circumference) | — |
Secondary
| Measure | Time frame |
|---|---|
| The following secondary outcome measures will be assessed at baseline, week 6, and week 18: 1. Resting metabolic rate measured using indirect calorimetry 2. Muscle growth and protein synthesis regulators (myostatin, IGF-1, P3NP, BDNF) measured using serum assays 3. Markers of inflammation (Nrf2, IL-1ß, IL-6, TNFa) measured using qRT-PCR (RNA isolated from blood samples) 4. Serum urolithins measured using liquid chromatography-mass spectrometry (LC-MS) for verification of Robuvit intake 5. Creatinine, urea, testosterone, glucose, and growth hormone (GH) levels measured using standard blood assays 6. Mitochondrial respiration measured using an O2k-Respirometer (Oroboros Instruments, Austria), respiratory function of liver mitochondria measured at 30°C using an amperometric measurement of oxygen consumption on an oxygraph Gilson 5/6 H (USA) equipped with a Clark-type oxygen electrode, and CoQ levels measured using a high-performance liquid chromatography (HPLC) method with spectrophotometric detection | — |
