What is the relationship between physical fitness level and macro- and micronutrient intake in Spanish older adults?

Purpose: The aim of this study was to assess the association between physical fitness (PF) and energy and nutrient intake in Spanish older adults.

Methods: Three hundred and twenty-four participants (59.9% females, aged over 55 years) performed a battery of four validated PF tests and participants were divided into three: low, medium, and high PF.

Seasonal variation and diet quality among Spanish people aged over 55 years.

Objective: To assess the impact of physical activity and sedentarism on fluid intake in Spanish elderly.

Methods: 433 non-institutionalized Spanish older adults (58% females), aged 55-88 years, volunteered for the PHYSMED study.

Evaluation of nutritional status and energy expenditure in athletes.

Continuous physical exercise leads the athlete to maintain an unstable balance between dietary intake, energy expenditure and the additional demands of a high amount of physical activity. Thus, an accurate assessment of nutritional status is essential to optimize the performance, since it affects health, body composition, and the recovery of the athlete. Specific aspects like the type of sport, specialty or playing position, training schedule and competition calendar, category, specific objectives, which differ from the general population, must be considered.
