Brief summary
FIT-AGING will determine the effect of different exercise modalities on α-Klotho protein (primary outcome) in sedentary healthy adults. FIT-AGING also investigate the physiological consequences of activating Klotho gene (secondary outcomes).
Detailed description
Aims: The plasma Klotho protein concentration (α-Klotho protein), which is considered a powerful biomarker of longevity, makes it an attractive target as an anti-aging therapy against functional decline, sarcopenic obesity, metabolic and cardiovascular diseases, osteoporosis, and neurodegenerative disorders. Physical exercise and physical fitness, could be α-Klotho protein activators through biochemical process. FIT-AGING will determine the effect of different exercise modalities on α-Klotho protein (primary outcome) in sedentary healthy adults. FIT-AGING also investigate the physiological consequences of activating Klotho gene (secondary outcomes). Methods: FIT-AGING will recruit 60 sedentary, healthy, adults (50% women) aged 40-65 years. Eligible participants will be randomly assigned to a non-exercise group to the usual control group (n=15), physical activity recommendation from American College of Sport Medicine, World Health Organization and American Heart Association group (n=15), High Intensity Interval Training group (n=15)) and Whole-Body Electromyostimulation group (n=15). Laboratory measures completed at baseline and 12 weeks later, include α-Klotho protein concentration, physical fitness (cardiorespiratory fitness, muscular strength), body composition, resting metabolic rate, hearth rate variability (HRV), health blood biomarkers, free-living physical activity, sleep habits reaction time, cognitive variables and health-related questionnaires. The investigators will also obtain dietary habits data and cardiovascular disease risk factors.
