Sedentary Activities

It is more difficult in many ways to carry out physical activities for people with visual impairments. The negative trends of contemporary lifestyle related to the imbalance of energy intake and expenditure may lie on them in the increased rate. They do not have too many opportunities for the energy expenditure. The most commonly reported physical activities of people with visual impairments include walking. But its realization may be associated with a number of problems. The aim of the study was to find out the volume of everyday physical activities in comparison with the passive relaxation and to find out to which extent they are a part of everyday life of people with visual impairments. We investigated the indicators characterizing the applied physical activity and inactivity during the week among the citizens with the visual impairment in the Usti Region (n = 15) using the short version of the IPAQ questionnaire. The acquired data were converted to values MET and MET-min · week–1. In the total volume of reported activities during the week (2 967 MET-min · week–1) there is a big volume of walking (2 222 MET-min · week–1). We tried to objectify the acquired data by using pedometers and it showed low volumes of steps for selected individuals. It turns out that only a small proportion of people with visual impairments fulfil more of the medical recommended criteria. Their lifestyle may suffer from an excess of sedentary activities that may adversely affect health. We recommend supporting their activity by the presence of tracers, improvements in navigation and preparation of specific programmes. We also see the arrangements at the level of local politics.

This study examined the relationship between intrapersonal correlates and being sufficiently active for health benefits in youth and adolescents (12-17 years of age). Participants completed questionnaires that assessed physical activity in the form of energy expenditure and intrapersonal correlates. Being in the sufficiently active group (> 8 kcal per day per kg of body weight) was associated with engaging in a greater array of physical activities, reporting greater levels of health, reporting a better home life, and spending less time in sedentary activities. The results provided preliminary evidence that selected intrapersonal correlates were associated with youth and adolescents who were sufficiently active to attain health benefits.

ABSTRACT Objective: To assess the physical activity level (PAL) and the total daily energy expenditure (EE-TDEE) in a sample of ≥60y subjects from Niterói, Rio de Janeiro, Brazil. Methods: A convenience sample of 88 subjects recruited from recreational physical activity programs wore an accelerometer around the waist for seven consecutive days for at least 10h/day. Minute-by-minute EE was estimated from the counts per minute (CPM) data, and the daily sum yielded the TDEE. PAL (TDEE/BMR) with BMR calculated with the FAO/WHO predictive equation and a population-specific equation. Body composition was assessed by DXA. Results: Mean age (SD) was 69.2 (5.8) years, the prevalence of overweight and obesity was 36.4 and 25.0%, respectively, and excess body fat was 39.8%. The subjects spent 600min/day engaged in sedentary activities (CPM<100). Men engaged in 30min of moderate-to-vigorous physical activity (CPM≥1,952) daily, on average. The subjects were active on 34.5 and 18.0% of the weekdays and weekend days with a 1,400 steps/day difference between these days. TDEE was 1,731.5 (348.7) and 1,356.3 (223.7) kcal/day depending on the BMR prediction equation used. Mean PAL was lower than the maintenance level. Conclusions: The high prevalence of sedentary activities and the low percentage of subjects who met the physical activity recommendations indicate that physical activity programs must be adjusted so that the enrolled subjects can meet the physical activity recommendations, preferably with the activities objectively monitored. Population-specific equations improve the final estimation of TDEE and PAL. Level of Evidence I; Diagnostic studies - Investigating a diagnostic test.

Introduction: This study sought to examine: (a) the associations between physical activity, sedentary time, and sleep duration, as discrete behaviors, with depression among adults with visual impairments; and (b) the impact of meeting none, one, two, or three of the guidelines for these behaviors on depression among adults with visual impairments. Materials: One hundred eighty-two ( Mage = 44.8) adults with visual impairments, recruited via email through two visual impairment organizations in the United States, completed the International Physical Activity Questionnaire–Short Form, a sleep duration question, the Major Depression Inventory, and a demographic questionnaire. Based on results from the questionnaires, dichotomous variables for meeting or not meeting physical activity, sleep, and sitting guidelines were created. Data were analyzed using three components: a descriptive analysis, Pearson product-moment correlation analyses, and hierarchical regression analyses. Results: Overall, 14.8% of participants were categorized as having some degree of depression. Meeting the sleep guideline was a significant negative predictor of depression scores in the hierarchical regression analyses. The number of guidelines met was a negative predictor for depression score controlling for other variables. Discussion: Adequate sleep, as well as meeting all three guidelines synergistically, was meaningful in influencing depression among this population. The current study’s results should prompt the continued examination of health-behaviors among adults with visual impairment using a more holistic 24-hour activity cycle framework. Implications for practitioners: This study supports the utilization of multi-behavioral interventions to reduce the risk of depression by enhancing physical activity and sleep, while reducing sitting time, among this population.

Background:The aim of this study is to establish the energy expenditure (EE) of a range of child-relevant activities and to compare different methods of estimating activity MET.Methods:27 children (17 boys) aged 9 to 11 years participated. Participants were randomly assigned to 1 of 2 routines of 6 activities ranging from sedentary to vigorous intensity. Indirect calorimetry was used to estimate resting and physical activity EE. Activity metabolic equivalent (MET) was determined using individual resting metabolic rate (RMR), the Harrell-MET and the Schofield equation.Results:Activity EE ranges from 123.7± 35.7 J/min/Kg (playing cards) to 823.1 ± 177.8 J/min/kg (basketball). Individual RMR, the Harrell-MET and the Schofield equation MET prediction were relatively similar at light and moderate but not at vigorous intensity. Schofield equation provided a better comparison with the Compendium of Energy Expenditure for Youth.Conclusion:This information might be advantageous to support the development of a new Compendium of Energy Expenditure for Youth.

One of the aims of Identification and Prevention of Dietary- and Lifestyle-Induced Health Effects in Children and Infants (IDEFICS) validation study is to validate field measures of physical activity (PA) and energy expenditure (EE) in young children. This study compared the validity of uniaxial accelerometry with heart-rate (HR) monitoring vs. triaxial accelerometry against doubly labeled water (DLW) criterion method for assessment of free-living EE in young children. Forty-nine European children (25 female, 24 male) aged 4–10 yr (mean age: 6.9 ± 1.5 yr) were assessed by uniaxial ActiTrainer with HR, uniaxial 3DNX, and triaxial 3DNX accelerometry. Total energy expenditure (TEE) was estimated using DLW over a 1-wk period. The longitudinal axis of both devices and triaxial 3DNX counts per minute (CPM) were significantly ( P < 0.05) associated with physical activity level (PAL; r = 0.51 ActiTrainer, r = 0.49 uniaxial-3DNX, and r = 0.42 triaxial Σ3DNX). Eight-six percent of the variance in TEE could be predicted by a model combining body mass (partial r2 = 71%; P < 0.05), CPM-ActiTrainer (partial r2 = 11%; P < 0.05), and difference between HR at moderate and sedentary activities (ModHR − SedHR) (partial r2 = 4%; P < 0.05). The SE of TEE estimate for ActiTrainer and 3DNX models ranged from 0.44 to 0.74 MJ/days or ∼7–11% of the average TEE. The SE of activity-induced energy expenditure (AEE) model estimates ranged from 0.38 to 0.57 MJ/day or 24–26% of the average AEE. It is concluded that the comparative validity of hip-mounted uniaxial and triaxial accelerometers for assessing PA and EE is similar.

Physical activity and fitness have long been associated with health, yet youth with visual impairments tend to be less active and less fit than their sighted peers. Performance calibration (i.e., the degree to which predictions about performance reflect actual performance) may be a useful conceptual framework to investigate the relationships between perceptions of health-related fitness and measured fitness performance among youth with visual impairments. The purpose of this study was to examine the predictive and postdictive performance calibration of youth with visual impairments on a test of cardiovascular fitness. Twenty-five participants (12 female, 13 male, aged 10–17 years) completed a 6-min endurance run test. Before and after the test, participants estimated how far they would run. Based on these data, performance calibration scores were calculated, and variables were correlated. Gender and visual impairment level-based differences were compared using t tests. Participants were generally overconfident in their predicted run scores but underconfident in their postdictions. Results of the present study suggest that youth with visual impairments are generally poorly calibrated with regard to cardiovascular fitness.

La obesidad y el sobrepeso se están convirtiendo en uno de los trastornos más importantes que se dan sobre todo en los países desarrollados. Existen varios factores que pueden influir en el aumento del IMC en niños con edad escolar ligados al desarrollo de la sociedad actual, como son la disminución de actividad física, una dieta desequilibrada o un aumento en actividades sedentarias. Este estudio se realizó sobre 315 escolares con edad entre 10 y 12 años y pertenecientes a la ciudad de Granada. Se pretende analizar y relacionar el género con los parámetros de obesidad, actividades sedentarias y físicas y la calidad de la dieta. Los resultados arrojaron que la mayoría de alumnado perteneciente a primaria se encuentra dentro del normopeso y tienen una dieta óptima sin haber significación respecto al género.Los varones solían pasar más horas realizando actividades sedentarias que las niñas. Sin embargo los chicos suelen realizar más actividad física que las chicas. Como conclusión, se demuestra la necesidad de realizar intervenciones para motivar a la realización de deporte, sobre todo en el sector femenino además de concienciar a los jóvenes de las consecuencias del sedentarismo y la obesidad. Abstract. Obesity and overweight are becoming one of the most important disorders existing on developed countries. There are various causes which influence children IMC increase such as physical activity decrease, an unbalanced diet, or sedentary activity rising. To gather information, 315 students belonging to Granada´s city from 10 to 12 years old have been used. It is intended to describe and relate gender with obesity, sedentary and physical activities and diet quality. Results showed that almost all primary education students were in a normal weight and had a balanced diet. Boys used to spend more time on sedentary activities but they also spend more time on physical activities than girls. The findings bright to light the need of realizing interventions to motivate girls to increase their physical activity participation, and to educate young on the health consequences of sedentary and obesity.

Free Living Conditions

This is a validation study of the RT3 accelerometer for measuring physical activities of children in simulated free-living conditions. Twenty-five children age 12–14 years completed indoor testing, and 18 of them completed outdoor testing. Activity counts from the RT3 accelerometer estimated activity energy expenditure (AEE) and the Cosmed K4b2 analyzer measured oxygen uptake. Correlations were found between activity counts and metabolic cost (r = .95, p < .001), metabolic cost and RT3 estimated AEE (r = .96, p < .001) in the indoor test, activity counts and RT3 estimated AEE (r = .97, p < .001) in the outdoor test, and activity counts and metabolic cost when all activities were combined (r = .77, p < .001). Results indicate that the RT3 accelerometer might be used to provide acceptable estimates of free-living physical activity in children.

Line Analysis

Acknowledging and understanding parental perceptions and experiences surrounding physical activity (PA) is crucial to promoting participation in PA for children with visual impairments (VI) given that parents strongly influence their children’s participation in physical activities. The purpose of this study was to understand parents’ perceptions regarding PA experiences for their family and children with VI. Participants in this study were parents of children with VI ( N = 10) who took part in one-on-one semi-structured phone interviews that were transcribed and then analyzed through a thematic line-by-line analysis. Two themes emerged from the analysis of the data: (1) Health, Social, and Psychological Benefits and (2) Multifaceted Barriers. The parents in this study valued PA and had high PA expectations for their children; however, they struggled to overcome multiple barriers - most notably their limited ability to motivate their children to be physically active.
