Poor Agreement between Responses to the International Physical Activity Questionnaire and Objective ActiGraph Data among Persons with Major Depressive or Bipolar Disorders.

The purpose of this research was to investigate the degree of agreement between data from the International Physical Activity Questionnaire-Short Form (IPAQ) and accelerometer (ActiGraph) readings for physical activity (PA), classified as moderate, vigorous, and moderate-vigorous PA, and sedentary behavior (SB) in participants with major depressive or bipolar disorder. Following a cross-sectional observational design ( = 30), participants used an accelerometer for 4 to 7 days (minimum of 10 h per day) and answered the IPAQ (for the same period as accelerometer use). Our results suggest significant differences ( < 0.

Supplement-based nutritional strategies to tackle frailty: A multifactorial, double-blind, randomized placebo-controlled trial.

Background: Sarcopenia plays a central role in the development of frailty syndrome. Nutrition and exercise are cornerstone strategies to mitigate the transition to frailty; however, there is a paucity of evidence for which dietary and exercise strategies are effective.

Objective: This large, multifactorial trial investigated the efficacy of different dietary strategies to enhance the adaptations to resistance training in pre-frail and frail elderly.

Number of high-protein containing meals correlates with muscle mass in pre-frail and frail elderly.

Background: Aging is accompanied by the inability to optimally respond to anabolic stimulus of nutrition, with consequent loss of muscle mass and functionality. It has been speculated that not only total protein intake, but also the per meal protein dose may have important implications to protein balance and, hence, muscle mass in middle-aged and older adults, but evidence is lacking in a more vulnerable population such as the frail elderly. The aim was to investigate possible associations between total protein intake and its per meal dose with multiple measures of muscle mass, strength, and functionality in a cohort of pre-frail and frail elderly individuals.

Different protein and derivatives supplementation strategies combined with resistance training in pre-frail and frail elderly: Rationale and protocol for the "Pro-Elderly" Study.

Background: Frailty is a multifactorial geriatric syndrome characterized by progressive decline in health and associated with decreased muscle mass, strength, and functional capacity. Resistance training (RT) combined with protein or amino acids supplementation has been shown to be promising for mitigating age-related impairments.

Aim: To investigate the chronic effects of different strategies of protein and derivatives supplementation in association with RT on selected health-related parameters in pre-frail and frail elderly.

The acute effects of static stretching on peak force, peak rate of force development and muscle activity during single- and multiple-joint actions in older women.

The present study investigated the acute effects of static stretching on peak force, peak rate of force development and integrated electromyography (iEMG) in 27 older women (65 ± 4 years; 69 ± 9 kg; 157 ± 1 cm; 28 ± 4 kg · m(-2)). The participants were tested during two exercises (leg press and knee extension) after two conditions: stretching and control. The data were collected on four days (counterbalanced with a 24-hour rest period).

[Spirulina, exercise and serum glucose control in diabetic rats].

Objective: The objective of this study was to analyze the effect of Spirulina and/or exercise training in the control of serum glucose homeostasis in diabetic rats.

Materials And Methods: Young Wistar rats were induced to diabetes by intravenous alloxan administration and separated into four groups: diabetic control (DC), diabetic Spirulina (DS), diabetic exercise (DE) and diabetic exercise Spirulina (DES).

Results: There were no differences between groups with respect to: body weight, food intake, glucose tolerance, insulin tolerance and blood lactate concentrations during a swimming effort test.
