“…This contrasts with earlier reports of declining levels of HPA for the majority of youth over a 5-year period of growth from childhood to adolescence, regardless of sex or weight status [26] and the trend of decreasing activity levels of children and youth in general [27]. It is possible that monitoring a patient's activity level while participating in a study may be a sufficient stimulus to effectively maintain what would otherwise be a predictable pattern of decreasing activity level with age [28]. This highlights a valuable opportunity to have a positive impact on lung function decline, by promoting a physically active lifestyle throughout childhood, to encourage the maintenance of activity and enhance the carry-over into adulthood [29].…”

Exercise is beneficial for patients with cystic fibrosis (CF) but long-term effects of physical activity on lung function evolution are unknown. We evaluated the longitudinal relationship between changes in habitual physical activity (HPA) and rate of decline in lung function in patients with CF.We tracked HPA using the Habitual Activity Estimation Scale, forced expiratory volume in 1 s (FEV1) and Stage I exercise tests in 212 patients with CF over a 9-year period.Adjusting for sex, baseline age and FEV1, mucoid Pseudomonas aeruginosa and CF-related diabetes, mean¡SD FEV1 % predicted decreased by 1.63¡0.08% per year (p,0.0001) while mean¡SD HPA increased by 0.28¡0.03 h?day -1 per year (p,0.0001) over the study period. A greater increase in HPA was associated with a slower rate of decline in FEV1 (r50.19, p,0.0069). Dividing subjects into ''high'' and ''low'' activity (above or below the mean rate of change of activity, respectively), a steeper rate of FEV1 decline was observed for low (-1.90% per year) compared to high (-1.39% per year) (p50.002).Increases in HPA are feasible despite progression of lung disease and are associated with a slower rate of decline in FEV1, highlighting the benefit of regular physical activity, and its positive impact on lung function in patients with CF. @ERSpublications FEV1 declines at a lesser rate in patients with cystic fibrosis who increase their activity levels

“…Este instrumento ha tenido un uso relativamente reducido en la población pediátrica, por limitada cooperación en el proceso y confiabilidad puesta en duda, aun con adolescentes. Esto ha cambiado, y según estudios recientes, comparando el diario de actividad con acelerometría en niños o adolescentes, la validez de este instrumento fue calificada de razonable y moderada (19)(20)(21). Otras publicaciones han mostrado que los diarios de actividad pueden aplicarse en estudios con un número importante de sujetos, más de 300 en el trabajo de Pfitzner et al (22) en Alemania y 400 en el de Pearce et al (23) en Inglaterra.…”

“…La realidad parece intermediaria; si la validación del diario de actividad no fue tema del presente estudio, es un hecho que no ha sido bien establecida por otros. Algunos trabajos calificaron la validez del diario de actividad como moderada o razonable, aportando cifras o valores de correlación con acelerometria que no sobrepasan un r = 0,58 (20,21,26,28). Sin embargo, en 403 adolescentes portugueses, Machado-Rodrigues et al (19), compararon las cpm con el gasto energético de las actividades registradas por el diario y reportaron una asociación RHO de 0,65 en varones y 0,69 en mujeres.…”

Reduction of exercise capacity in children from summer to winter is associated with lower sporting activity: a serial study

et al. 2013

Background: Declining activity in children over the past decades is thought to be one of the main risk factors for an early development of exercise intolerance and obesity. Taking this background into account, this prospective study investigated the seasonal change of children's physical activity and its association with objective measures of exercise capacity. Methods: A total of 96 children from two schools in Munich (42 girls, age 12.4 ± 0.8 y) underwent a cardiopulmonary exercise test (CPET) and an assessment of their daily activities (school sport, club sport, leisure sport) twice. Baseline testing was conducted in summer 2011. Follow-up examination was performed during winter 2012. results: From summer to winter, self-reported sporting activity decreased from 10.6 ± 4.1 to 8.5 ± 4.3 h/wk (P < 0.001) as school sport (P < 0.001) and leisure sport activities (P = 0.002) decreased, but the activity associated with club sport did not (P = 0.700). In parallel, peak oxygen uptake (VO 2 ) declined from 102.0 ± 17.5 to 96.9 ± 17.9 % of predicted (P < 0.001). This decline in VO 2 was associated with a reduction in overall sporting activity (r = 0.234; P < 0.032). conclusion: Enhancing sporting activity in children during winter might be important to maintaining their exercise capacity. P hysical activity is important for metabolic and mental health in adults as well as in children (1-7). Schoolchildren should participate on a daily basis in 60 min or more of moderate to vigorous physical activity that is developmentally appropriate, enjoyable, and involves a variety of activities (4,6,8). Unfortunately, the activity levels of children (and also adults) are decreasing in our Western industrialized countries (9-11), and more than 60% of the world's population does not engage in enough physical activity (6,11). As if that were not enough, a study suggests (1) that those recommendations for daily activity were too low to reduce the clustered cardiovascular risk of children.Regarding the seasonal change in daily activity, fewer data are available. In a recent review article (12) on accelerometerdetermined physical activity data in children, only four studies (13-16) with a longitudinal design were identified. All except one (14-16) reported on significant lower activity pattern during winter. Those findings were supported in other review articles (12,17). However, whether that decrease in activity during winter was also associated with a reduction of exercise performance was not examined in the mentioned studies.Therefore, this study aimed to compare the seasonal change in activity levels in children with their objective measured exercise performance obtained with a cardiopulmonary exercise test (CPET). Exercise capacity is positively associated with daily activity (5,18,19), and peak oxygen uptake (VO 2 ), the gold standard measurement of exercise capacity, has also been shown to be of predictive value in apparently healthy adults (20), as well as in patients with several diseases (20-23). (Table 1), children reported t...
