Show moreThis 12-week randomized controlled trial investigates the effects of different training modalities on cardiometabolic risk in sedentary, middle-aged adults, and examines whether alterations in cardiometabolic risk are associated with changes in those health-related variables that are modifiable by exercise training. The study subjects were 71 middle-aged adults (similar to 54 years old; similar to 50% women) who were randomly assigned to one of the following treatment groups: (1) no exercise (control group), (2) concurrent training based on international physical activity recommendations (PAR group), (3) high intensity interval training (HIIT) group, or (4) HIIT plus whole-body electromyostimulation (HIIT+EMS group). A cardiometabolic risk score was calculated based on the International Diabetes Federation's clinical criteria. A significant reduction in cardiometabolic risk was observed for all exercise training groups compared to the control group (all p < 0.05), which persisted after adjusting potential confounders (all p < 0.05). However, the HIIT+EMS group experienced the most significant reduction (p < 0.001). A significant inverse relationship was detected between the change in lean mass and the change in cardiometabolic risk (p = 0.045). A 12-week exercise training programs-especially the HIIT+EMS program-significantly reduced cardiometabolic risk in sedentary, middle-aged adults independent of sex, age, and cardiorespiratory fitness.

Show moreIntroduction: The ageing process can be influenced by different dietary patterns and dietary factors.Aim: To analyse the association of dietary factors, which include the Mediterranean diet adherence, the compliance with the "Sociedad Espanola de Nutricion Comunitaria" food portion recommendations, and the intake of different food groups, with the secreted form of the alpha-Klotho gene (S-Klotho as an anti-ageing marker) in middle-aged sedentary adults.Methods: A total of 74 (39 women) middle-aged sedentary adults participated in the study. Dietary factors were assessed with a food frequency questionnaire and the PREDIMED questionnaire. The S-Klotho plasma levels were measured using a soluble alpha-Klotho ELISA assay kit.Results: We observed: (i) a negative association between the adherence to the Mediterranean diet and the S-Klotho plasma levels (beta = - 53.219; R-2 = 0.078; P = 0.020), (ii) a higher intake of wine (> 7 glasses/week), was associated with lower S-Klotho plasma levels (P = 0.039), and (iii) a positive association between nuts portion intake and the S-Klotho plasma levels (beta = 26.087; R-2 = 0.070; P = 0.029). All the associations disappeared after controlling for lean mass index (LMI) (all P > 0.05).Conclusion: Our study suggests that, although dietary factors could be related to S-Klotho plasma levels in middle-aged sedentary adults, LMI is the main determinant in this regard.
