Physical Fitness and Body Composition in 8-10-Year-Old Danish Children Are Associated With Sports Club Participation.

ABSTRACT: Larsen, MN, Nielsen, CM, Ørntoft, CØ, Randers, M, Manniche, V, Hansen, L, Hansen, PR, Bangsbo, J, and Krustrup, P. Physical fitness and body composition in 8-10-year-old Danish children are associated with sports club participation. J Strength Cond Res 31(12): 3425-3434, 2017-We investigated whether physical fitness and body composition in 8-10-year-old Danish children are associated with sports club participation. The study included 423 schoolchildren, comprising 209 girls and 214 boys, of whom 67 and 74%, respectively, were active in sports clubs. Yo-Yo intermittent recovery level 1 for children (YYIR1C), balance, jump and coordination tests, together with dual-energy X-ray absorptiometry, were used to determine exercise capacity and body composition. Children active in sports clubs had better (p < 0.05) YYIR1C (33%, 767 ± 26 vs. 575 ± 29 m), 20-m sprint (3%, 4.33 ± 0.03 vs. 4.48 ± 0.04 seconds), coordination (6%, 68 ± 1 vs. 72 ± 1 second), and balance test performances (9%, 19.3 ± 0.5 vs. 21.2 ± 0.7 falls·min) and lower fat mass index (16%, 3.8 ± 0.1 vs. 4.5 ± 0.2 kg[fat]·m) than children not active in sports clubs. Ball game players had better (p < 0.05) YYIR1C (38%, 925 ± 39 vs. 671 ± 28 m), 20-m sprint (4%, 4.25 ± 0.03 vs. 4.42 ± 0.04 seconds), and coordination test performances (5%, 65 ± 1 vs. 69 ± 1 second), along with higher (p < 0.05) lean body mass (5%, 24.00 ± 0.22 vs. 22.83 ± 0.25 kg) and whole-body BMD (2%, 0.90 ± < 0.01 vs. 0.88 ± <0.01 g·cm) compared with children active in other sports. The study showed that 8[FIGURE DASH]10-year-old Danish children engaged in sports-club activity, especially ball game players, have better exercise capacity and superior body composition compared with children not active in sports clubs.

Project description:ObjectivesThis study investigated the correlation between sports club activities and well-being and physical health parameters in 10-12 years old boys.DesignCross sectional.SettingDanish schools.Participants2293 boys took part in the study.Primary and secondary outcome measuresQuestionnaires on participation in sports clubs and well-being and testing of physical health profile through measurement of body composition, resting heart rate (RHR), blood pressure and postural balance, jump and Yo-Yo IR1C performance. Data were analysed by participation in sport and according to the five most frequently reported sports.ResultsBoys enrolled in sports clubs had higher physical well-being (51.7±9.7 vs 45.9±8.7) and psychological well-being (53.3±9.6 vs 51.4±10.0), experienced more peers and social support (50.9±9.9 vs 48.0±11.6), and had a more positive perception of the school environment (48.6±7.5 vs 45.9±8.1) than boys not involved in sports clubs. In addition, they showed better Yo-Yo IR1C (+46%), long jump (9%) and balance test performance (+20%). The boys active in sports clubs had higher relative muscle mass (+6%) and lower fat percentage (-3%), body mass index (-6%) and RHR (-5%) compared with boys not involved in sports clubs (p<0.05). Boys enrolled in football clubs had higher aerobic fitness compared with boys not active in clubs (+11%), handball players (+5%), swimmers (+8%) and badminton players (+7%). Moreover, the boys enrolled in football clubs had lower fat percentage (-17%) and higher relative muscle mass (+4%) than swimmers.ConclusionBoys participating in club-based sports showed markedly higher levels of well-being and better physical health profiles than boys not involved in sports club activities. Footballers had superior aerobic fitness and body composition compared with those active in other sports. Results suggest that sports club activities seem to be beneficial for young boys' well-being, fitness and physical health profile, with the greatest benefits achieved by boys involved in football.

Project description:ContextTotal knee arthroplasty (TKA) is routinely performed in younger patients who desire to be active in fitness and recreational sports. The activities patients can participate in without symptoms and the level of aerobic fitness routinely maintained are important to investigate.ObjectiveTo determine physical activity (PA) and recreational sports resumed after primary TKA, symptoms or limitations with these activities, and the effect of postoperative rehabilitation on achieving fitness and sports goals.Data sourcesA systematic review of the literature from 2005 through 2015 was conducted using the PubMed database.Study selectionOriginal investigations that were conducted at least 1 year after primary TKA and reported the percentage of patients who returned to recreational activities or routinely participated in aerobic PA recommended by the American Heart Association (AHA) were included in this study.Study designSystematic review.Level of evidenceLevel 4.Data extractionData were extracted as available from 19 eligible studies. Assessment of study quality was rated using the MINORS (Methodological Index for Non-Randomized Studies) instrument.ResultsThere were 5179 knees (mean age, 67.5 years) followed for a mean 4.8 years postoperatively. Marked variability was present between studies regarding the percentage of patients who resumed recreational activities (34%-100%), most of which were low impact. Only 2 studies used accelerometers to measure PA; these reported a low range (0%-16.5%) of patients who met AHA guidelines. Few studies determined whether symptoms or limitations were experienced during PA. None described rehabilitation exercises or factors that would influence patients' ability to return to recreational or fitness activities.ConclusionLittle evidence is available regarding the effect of TKA on return to recreational and (objectively measured) aerobic fitness. The extent of symptoms or limitations during PA and the long-term effects of such problems remain unclear. Valid predictions cannot be made on factors that may affect return to recreational sports or other aerobic PA after TKA.
