The link between physical activity (PA) and prevention of disease, maintenance of independence, and improved quality of life in older adults is supported by strong evidence. However, there is a lack of data on population levels in this regard, where PA level has been measured objectively. The main aims were therefore to assess the level of accelerometer-determined PA and to examine its associations with self-reported health in a population of Norwegian older adults (65–85 years). This was a part of a national multicenter study. Participants for the initial study were randomly selected from the national population registry, and the current study included those of the initial sample aged 65–8…

Motivating Individuals With Disabilities to Be Physically Active

2002

The benefits of exercise andlor physical activity among individuals with disabilities have been well documented. However, very few people with disabilities are active. In this paper, a series of contemporary theoretical models will be presented to facilitate the identification of strategies to increase individuals with disabilities' opportunities and motivation toward physical activitylexercise. These models can be empirically tested by researchers, and practitioners can be guided by the hypothesized relationships to determine optimal strategies for motivating physical activity participation. This blend of theory, research, and practice in adapted physical activity scholarship may result in…

PO-279 Bidirectional Associations Between Physical Activity and Adiposity From Childhood to Early Adulthood

2018

Objective Inverse association between physical activity and adiposity in children and adolescents have been documented in numerous studies. However, few studies have examined the direction of causation between these two variables. We aimed to examine the prospective bidirectional associations between physical activity and adiposity from childhood to early adulthood.
 Methods A total of 396 girls (mean age, 11.2 years at baseline) participated in a longitudinal study with 1, 2, 4, and 7 year follow-ups. Body height and weight were measured, body composition was assessed by DXA and BMI and fat mass index (FMI) were calculated. Leisure-time physical activity (LTPA) and physical inactivity…

Adherence to a Mediterranean diet is associated with lower incidence of frailty: A longitudinal cohort study

2018

Background & aims There is a paucity of data investigating the relationship between the Mediterranean diet and frailty, with no data among North American people. We aimed to investigate if adherence to a Mediterranean diet is associated with a lower incidence of frailty in a large cohort of North American people. Methods This study included subjects at higher risk or having knee osteoarthritis. Adherence to the Mediterranean diet was evaluated using a validated Mediterranean diet score (aMED) as proposed by Panagiotakos and classified into five categories. Frailty was defined using the Study of Osteoporotic Fracture (SOF) index as the presence of ≥2 out of: (i) weight loss ≥5% between b…

Role of anthropometric factors, self-perception, and diet on weight misperception among young adolescents: a cross-sectional study

2018

Adolescence overweight and obesity have increased considerably, and the misperception of their weight status could reduce the efficiency of intervention programs. The aim of this study was to evaluate the prevalence rate of misperception and to assess the relationship between weight perception and anthropometric parameters, self-perception, physical activity, and adherence to the Mediterranean diet. A total of 1643 young adolescents (11–16 years old) were surveyed in a cross-sectional investigation during two scholastic years (period October–May of 2012–2013 and 2013–2014) in 15 secondary schools of Sicily, southern Italy. Data on demographic information, anthropometric characteristics (bio…

Effectiveness of School-Initiated Physical Activity Program on Secondary School Students' Physical Activity Participation

2013

BACKGROUND The promotion of physical activity and health has become a universal challenge. The Sotkamo Physical Activity as Civil Skill Program was implemented to increase students' physical activity by promoting supportive psychological and physical school environment. The aim of this study was to evaluate the effectiveness of the school-initiated physical activity program on secondary school students' self-reported physical activity. METHODS The sample included 847 students (experimental condition school = 208, control school = 639) at the age of 12 to 14 years from northeast and central Finland. The program was conducted across 1 academic year and 2 measurement phases were carried out us…

The Associations of Activity Fragmentation with Physical and Mental Fatigability among Community-Dwelling 75-, 80- and 85-Year-Old People

2020

Abstract Background Fatigue related to task standardized by duration and intensity, termed fatigability, could manifest as shortening of activity bouts throughout the day causing daily activity to accumulate in a more fragmented pattern. Our purpose was to study the association of activity fragmentation with physical and mental dimensions of fatigability. Methods A cross-sectional study of 485 community-dwelling 75-, 80-, and 85-year-old people using a thigh-worn accelerometer for 3–7 days. Activity fragmentation was studied as Active-to-Sedentary Transition Probability for 2 operational definitions of physical activity: accelerations equivalent to at least light physical activity and for u…

Adolescents' physical activity at recess and actions to promote a physically active school day in four Finnish schools

2014

The national Finnish Schools on the Move programme support schools with their individual plans to promote school-based physical activity (PA). We examined the changes in adolescents’ recess and overall PA in four lower secondary schools and described the school actions to promote students’ PA and the local contact persons’ perceptions of the effects. Recess and overall PA were assessed four times by anonymous questionnaires from students in grades 7–9 (n = 789) in 2010–12, and local contact persons (n = 7) provided information on school actions with diaries, interviews and surveys. Student data were analysed with descriptive statistics and chi-square tests, and school actions data were anal…

Prevalence of sarcopenia and associated factors in the healthy older adults of the Peruvian Andes

2016

Aim To assess the prevalence of sarcopenia and associated factors in a population of older people living in a rural area of the Peruvian Andes. Materials and methods The study concerned 222 people aged ≥65 years. Sarcopenia was diagnosed on the basis of skeletal muscle mass, measured using bioimpedance analysis, and gait speed, measured with the 4-m walking test, as recommended by the International Working Group on sarcopenia. Self-reported physical activity, the Short Physical Performance Battery, and the Six-Minute Walking Test also contributed information on participants’ physical performance status. Disabilities were investigated by assessing participants’ self-reported difficulties in …

Physical Activity in Adolescence as a Predictor of Alcohol and Illicit Drug Use in Early Adulthood: A Longitudinal Population-Based Twin Study

2009

AbstractWe investigated prospectively whether physical activity level in adolescence predicts use of alcohol and illicit drugs in early adulthood. We studied 4,240 individual twins (1,870 twin pairs). We classified those who consistently reported frequent leisure physical activity at ages 16, 17 and 181/2 as persistent exercisers, those exercising less than three times monthly as persistently inactive, and all others as occasional exercisers. To control for familial confounds, within-family analyses compared activity-substance use associations in co-twins discordant for baseline physical activity. Individual-based analyses showed no clear association between baseline physical activity and s…
