Design outcomes

Primary

MeasureTime frame
-The anthropometric parameters (BMI, body weight, fat and free mass, waist circumference) -Glycemic variability: Continuous Glucose Monitoring System (e.g., estimated HbA1c, hypoglycemia and hyperglycemia episodes, fasting blood glucose, instantaneous blood glucose) -Biological responses: fasting glucose, serum insulin levels, HOMA-IR, CGMS for 14 days; lipid profile (total cholesterol, LDL, HDL, triglyceride, Short-Chain Fatty Acids, glycated hemoglobin (HbA1C); oxidative stress (malondialdehyde (MDA) ,Thiol, glutathione peroxidase (GPx)); vitamin D; Carbonyl protein , Advanced oxidative protein product (AOPP), interleukin 6 (IL-6) hormones (leptin, insulin, melatonin, adiponectin, resistin, cortisol);NFS (e,g., lymphocytes, neutrophil, hematocrits) cellular damage (ASAT, ALAT, CPK, LDH, CRP); immunology and inflammation (IL-6), 6-sulfatoxymelatonin. -Physiological parameters: resting heart rate (HRrest), maximum heart rate (HRmax), Mean Heart Rate (Mean HR), Heart rate variability parameters (Kubios) (e.g., very low frequency (VLF), low frequency (LF), high frequency (HF), Standard Deviation of Normal-to-Normal Intervals (SDNN), Mean R-R Interval (Mean RR)), -Cardiorespiratory fitness: clinical ergocycle (e.g., heart rate (HR), blood pressure (BP)). During the exercise test, we will evaluate oxygenated and deoxygenated hemoglobin muscle (O2Hb and HHb) using near-infrared spectroscopy (NIRS).

Secondary

MeasureTime frame
-Physical capacity: chair test and 30” bicep flexion test, postural balance (force platform), -Quality of life (Medical Outcomes Study Short Form 36 (SF-36)), chronotype (Caen chronotype questionnaire), International Physical Activity Questionnaire (IPAQ), Sleep quality and quantity (Pittsburgh sleep quality index, sleep dairy and actimetry). Psycho-cognitive status (e.g., Montreal Cognitive Assessment (MoCA questionnaire), Hospital Anxiety and Depression Scale (HADS)) , Hunger and Satiety Visual Analogue Scales (VAS),Eating Attitudes Test (EAT 26).
