Effect of a nutritional intervention associated with different models of physical training on health parameters of adult and elderly women: A Randomized Trial

Abstract

Objective This study aimed to investigate the effect of different training models associated with a nutritional intervention program in physically active women aged 50 to 70 years. Methods Participants were randomly assigned to four training groups (CT with nutritional intervention, CT without nutritional intervention, MT with nutritional intervention, and MT without nutritional intervention) and evaluated before and after 14 weeks of training for anthropometric measurements, body composition, blood pressure, metabolic parameters, blood analyses, physical capacities, level of physical activity, and quality of life. Results The CT group showed a reduction in body mass and improvement in lower limb endurance, agility, lower and upper limb strength, and cardiorespiratory capacity. In the MT group, a positive response was observed in lower limb muscle strength, waist circumference, and the mental domain related to quality of life. Conclusion The groups with nutritional intervention showed better performance in sodium, protein, and calcium consumption parameters, as well as improvement in quality of life and level of physical activity. No difference was found between nutritional intervention associated with the two different types of training. These results suggest that a nutritional intervention program associated with different physical training models can be beneficial for physically active women between 50 and 70 years of age.
