“…In agreement with our findings, some other studies could not confirm a negative association between PA and body fatness (36,37) or found that underweight adolescents were less likely to be physically active (10) .…”

Objective: To describe self-reported physical activity (PA) patterns in the various domains (school, home, transport, leisure time) and intensity categories (walking, moderate PA, vigorous PA) in European adolescents. Furthermore, self-reported PA patterns were evaluated in relation to gender, age category, weight status category and socio-economic status (SES). Design: Cross-sectional study. Setting: Ten European cities. Subjects: In total, 3051 adolescents (47?6 % boys, mean age 14?8 (SD 1?2) years) completed an adolescent-adapted version of the validated International Physical Activity Questionnaire. Results: The total sample reported most PA during leisure time (485 min/week) and least PA at home (140 min/week). Boys reported significantly more school-based PA (P , 0?001), leisure-time PA (P 5 0?003), vigorous PA (P , 0?001) and total PA (P 5 0?002) than girls, while girls reported more home-based PA (P , 0?001) and walking (P 5 0?002) than boys. Self-reported PA at school (P , 0?001), moderate PA (P , 0?001), vigorous PA (P , 0?001) and total PA (P , 0?001) were significantly higher in younger age groups than in older groups. Groups based on weight status differed significantly only in leisure-time PA (P 5 0?004) and total PA (P 5 0?003), while groups based on SES differed in all PA domains and intensities except transport-related PA and total PA. Conclusions: The total sample of adolescents reported different scores for the different PA domains and intensity categories. Furthermore, patterns were different according the adolescents' gender, age, weight status and SES.

“…Similarly, Katzmarzyk et al 32 analyzed 356 boys and 284 girls (9-18 years) from the Québec Family Study and found a weak association between PA and static strength of the legs in a maximal voluntary isometric contraction at a knee angle of 90° and a low no significant association between PA and sum of 6 skinfolds. Ara et al 18 showed in 114 prepubertal boys (9.4±1.5 years) that participation in at least 3 hours per week of extracurricular physical activities and sport competitions was associated with higher squat jump performance and lower fat mass levels compared with non-participants.…”

Association of physical activity with muscular strength and fat-free mass in adolescents: the HELENA study

et al. 2010

Objective: To analyze the association of objectively assessed physical activity (PA) with muscular strength and fat free mass in adolescents, and to determine whether meeting the current PA recommendations is associated with higher levels of muscular strength and fat free mass. Subjects Results:We observed positive associations between vigorous PA and all the lower body muscular strength tests except for the counter movement jump in males. PA was not associated with fat free mass in both males and females. Male adolescents engaged in at least 60 min/day MVPA performed better in the standing broad jump test. Conclusions:The findings of the present study suggest that only vigorous PA is associated with muscular strength, particularly lower-body muscular strength in male adolescents.

“…In this case, the daily activities are classified in a continuum involving nine categories, according to estimates concerning mean caloric cost of the activities performed by humans: (1) rest in bed; (2) activities performed at sitting position; (3) mild activities performed at standing position; (4) activities which involve mild walks (< 4 km/ hour); (5) mild hand labor; (6) active leisure activities and practice of recreational sports; (7) moderate hand labor; (8) active leisure activities and moderate sports practice; and (9) intense hand labor and practice of competitive sports. Since it is practical, innocuous and easy to be interpreted, the present instrument has been widely accepted and used in other studies involving young populations (25,(35)(36)(37)(38) . The retrospective instrument was filled out by the adolescents themselves in four days of the same week, two in the middle (between Monday and Friday) and two on the weekend (Saturday and Sunday).…”

The aim of the present study was to analyze the impact of regular practice of physical activity facing estimates of daily energy expenditure (EE daily ) in the plasmatic lipid-lipoprotein profile in a representative sample of adolescents. The sample consisted of 452 subjects (246 females and 206 males), age between 15 and 18 years. The plasmatic lipid-lipoprotein concentrations were established through laboratory procedures. The data concerning the regular practice of physical activity were obtained though a retrospective instrument of self-recording. Estimates concerning the EE daily were established based on the caloric cost associated with the type and the duration of the activities registered by the adolescents. The sample was divided in three groups of regular practice of physical activity: the least active, < 25 o percentile of the EE daily ; the moderately active, o percentile of the EE daily ; and the most active, > 75 o percentile of the EE daily . Cutting points for an atherogenic lipid-lipoprotein risk were also established. The results of the analysis of covariance, having the participation of the body mass index controlled, showed that the HDL-C concentrations were significantly different according to the growing groups of EE daily in females (p = 0.009) and in males (p = 0.010). However, the variation behavior of the values observed was different in the two sexes. The analysis of logistic regression showed that the relative risk for lower values of HDL-C was two times higher among the least active adolescents comparing with the most active ones. In both sexes the concentrations of total cholesterol, LDL-C and triglycerides did not present significant differences among the groups of EE daily . In conclusion, more intense regular practice of physical activity as well as higher EE daily are associated with higher concentrations of HDL-C in adolescents of both sexes, regardless of the variations of body weight. The associations between EE daily and the other plasmatic components of lipid-lipoproteins treated in the present study were weak and inconsistent.

Physical activity and health-related fitness in youth: amultivariate analysis

Abstract: There is a significant relationship between activity and health-related physical fitness, but a large part of the variability (80-90%) in fitness is not accounted for by physical activity as measured in this study.
