Thursday 1 November Posters / Journal of Science and Medicine in Sport 15 (2012) S127–S187
Results: Groups did not differ in any analyzed variables (40–45 yrs group–HI right: 45.47 ± 6.3 kgf; HI left: 42.72 ± 4.9 kgf; MVPA: 666 ± 529 min/wk; WHOQOL total score: 82.06 ± 10.76; 46–59 yrs group–HI right: 44.23 ± 9.1 kgf; HI left: 41.89 ± 8.76 kgf; MVPA: 753 ± 412 min/wk; WHOQOL total score: 80.05 ± 6.96; >60 yrs group–HI right: 44.46 ± 12,43 kgf; HI left: 42.47 ± 11.33 kgf; MVPA: 797 ± 479 min/wk; WHOQOL total score: 78 ± 7). Significant correlations were observed between age and right side IH (r = -.33, p=.038), MVPA amount and two QoF domains, physical (r = 43, p=.006) and psychological (r=.38, p=.017), as well as total score (r=.47, p=.002). Discussion: To these master judo athletes, IH have no difference over the years and they practice several minutes of moderate-tovigorous physical activities. In this population, the MVPA amount, but not light activities, was correlated with different QoL domains, providing maintenance of athletes’ functional status and can be stimulated in this population. http://dx.doi.org/10.1016/j.jsams.2012.11.392 390 Daily physical activity pattern related to total body fat and abdominal fat in younger children M.

Introduction: Lack of physical activity is generally thought to be associated with obesity in children. Previous studies have, however, produced conflicting results. We assessed if different aspects of physical activity is related to different measurements of body fat in children aged 8 to 11 years. Methods: Cross-sectional study of 226 children (125 boys and 101 girls), recruited from a population-based cohort. Accelerometers measured minutes of inactivity (IA), moderate and vigorous physical activity (MVPA) and vigorous physical activity (VPA) per day. Total body fat mass and abdominal fat mass were measured by a DXA scan. Total body fat was expressed as percentage of body mass (BF%). Skewed values were normalised by natural logarithm. Results: Boys performed significantly more minutes of MVPA and VPA per day compared to girls (MVPA 45 ± 20 vs 35 ± 13 and VPA 15 ± 10 vs 11 ± 7, all P < 0.05). No difference was found for IA (508 ± 75 vs 522 ± 68, P = 0.13). Girls had higher BF% than boys (22 ± 9 vs 16 ± 9, P < 0.05) and more AFM (3.3 ± 2.4 vs.2.4 ± 2.3, P < 0.05). Pearson correlation indicated a significant association in boys between MVPA and VPA vs BF% (r = -0.29 and -0.32, P < 0.05) and vs AFM (r = -0.28 and -0.31, P < 0.05). IA was not related to BF% or AFM (r = 0.12 and 0.12, P > 0.05). The corresponding findings in girls; MVPA and VPA vs BF% (r = -0.38 and -0.47, P < 0.05) and vs AFM (r = -0.31 and -0.41, P < 0.05). IA was not related to BF% or AFM in boys (r = 0.12 and 0.12, P > 0.05) or in girls (r = -0.08 and -0.13, P > 0.05). Conclusions: In this population-based cohort of children minutes of MVPA and VPA per day were related to amount of body fat in both boys and girls, whereas minutes of IA per day was not. This indicates that low physical activity, not inactivity, can be a contributing factor in the development and/or maintenance of obesity in children. http://dx.doi.org/10.1016/j.jsams.2012.11.393

Introduction: Aerobic fitness (VO2 peak) is a strong, independent risk factor for cardiovascular disease and mortality in adults. It is therefore of interest to investigate how VO2 peak is related to different aspects of daily physical activity already in childhood. We assessed if different measures of physical activity is related to VO2 peak in children aged 8 to 11 years. Methods: Cross-sectional study of 226 children (127 boys and 101 girls), recruited from a population-based cohort. Accelerometers measured minutes of inactivity (IA), moderate and vigorous physical activity (MVPA) and vigorous physical activity (VPA) per day. VO2 PEAK was assessed by indirect calorimetry during a maximal exercise test and scaled by body mass (ml/min/kg). Results: Boys had higher VO2 peak than girls (45.8 ± 7.4 vs 34.7 ± 6.3, P < 0.05). Boys performed significantly more minutes of MVPA and VPA per day than girls (MVPA 46 ± 20 vs 35 ± 13 min, VPA 15 ± 10 vs 11 ± 7 min, all P < 0.05). There was no difference in IA (506 ± 77 vs 522 ± 68 min, P = 0.09). Pearson correlation indicated a significant association between MVPA and VPA versus VO2 peak . In boys r = 0.32 and 0.26, and in girls r = 0.30 and 0.31, all P < 0.05. IA was not related to VO2 peak, in boys r = 0.05, and in girls r = 0.07, both P > 0.05. Conclusions: In this population-based cohort of children minutes of MVPA and VPA per day were related to VO2 peak in both boys and girls, whereas minutes of IA was not. http://dx.doi.org/10.1016/j.jsams.2012.11.394 392 Metabolic health in the overweight and obese, what is the role of physical activity? C. Dillon ∗ , P. Kearney, I. Perry, V. McCarthy University College Cork Introduction: The prevalence of overweight and obesity is increasing worldwide. In Ireland, approximately two-thirds of the population are overweight or obese. It is well established that physical inactivity plays a major role in the development of overweight and obesity and that being overweight and obese predisposes an individual to metabolic abnormalities. But some individuals maintain metabolic health despite being overweight and obese and the mechanism for this is unclear. The objectives of this paper are to establish the prevalence of metabolically healthy overweight and obese in middle-aged Irish adults and to examine the effect of physical activity on metabolic health among overweight and obese. Methods: A population representative random sample of men and women were recruited from a large primary care centre in Mitchelstown, County Cork, Ireland. Baseline assessment included a health questionnaire and a physical examination undertaken by trained study nurses and included standardised measurement of height, weight, blood pressure, and venous blood sampling. Physical activity was measured with the International Physical Activity Questionnaire (IPAQ) and categorised into high, moderate and low levels. Participants were classified as overweight, BMI≥25 kg/m2 , or obese, BMI≥30 kg/m2 . Metabolically healthy was defined as; blood
