PURPOSE: This study was conducted to determine the effects of 8 week summer lifestyle intervention and 10 month follow-up telephone intervention on changes in levels of physical fitness and lipid profiles in Hispanic Children. METHODS: 41 overweight or obese students (9-14yrs) completed 8 week summer lifestyle intervention. Students were later randomly assigned to follow-up telephone intervention for 10 months (TI) and control (CON). %body fat, flexibility, estimated VO 2max , muscular strength, and blood samples were obtained before, a week after (POST) and 10 months following 8 week summer intervention (YEAR). RESULTS: 8 weeks of lifestyle intervention significantly improved % body fat, estimated VO 2max , flexibility, muscular strength, and lipid profiles (P value between PRE vs. POST for all variables were less than .02) in both groups. While the improvement in CON returned to PRE values during 10 month follow-up period, TI statistically maintained these changes up to 10 months with follow-up telephone intervention: %body fat (PRE:28.2±2.1%→POST:24.8±2.1→YEAR:25.9±2.3, Mean±SE, P value between PRE vs. YEAR=.017), flexibility (27.61.5cm→31.5±1.5→30.6±1.8, P=0.046), estimated VO 2max (40.9±1.6ml·kg -1 · min -1 →45.7±1.7→43.2±1.6, P=.021), cholesterol (146.2±3.8→135.7±3.9→139.2±3.7, P=.036), TG (126.7±4.1→96.8±4.7→106.9±4.5, P=.024), HDL-C (32.7±1.3→44.9±1.7→40.2±1.4, P=.036), and LDL-C (88.2±3.5→71.4±3.3→77.6±3.7, P=.029). Muscular strength was slightly increased in both TI and CON, but it was not significant. CONCLUSION: 8 week summer lifestyle intervention improved levels of physical fitness and lipid profiles in Hispanic children. Results indicate that telephone intervention is an effective tool to maintain the improvement in levels of fitness and lipid profiles obtained from an intensive summer lifestyle intervention program. 2488 Board #235 May 29, 9:30 AM - 11:00 AM Effects Of 2-year Intervention Program On Functional Capacity Of Nursing Residents Sandra M.

METHODS: sample was composed by 79 elderly living in 6 nursing homes in São Caetano do Sul (São Paulo -Brazil). Sample was divided in two groups: one group took part in the physical activity (PA) intervention including strength, mobility, flexibility and aerobic exercises twice a week, 50 minutes per session performed in the living room of each institution (Baseline [N=46], age equals to 74.1 SD 11.1). The other group received information about the benefits of PA and some suggestions in how to increase the daily PA in the institution (Baseline [N=33], age equals to 73.2 SD 13.2). Assessments of functional capacity at baseline, 1 year and 2 years were performed after the start of program. At the beginning of intervention 79 elderly were included in the intervention. After 2 years a final sample of 53 elderly were followed-up.Physical function was measured through grip strength, Arm Curl (counts), 30-s chair stand (counts), Flexibility (cm), TUG (sec), Static balance (sec), Usual Walking (sec), Walking speed (sec), velocity in rising from a chair (seg), 2-min Step test (counts) Statistics: non-parametric data are presented in mean and interquartile range, to compare the groups before and after the intervention were used Wilcoxon and Mann-Whitney test RESULTS: the control group presented higher values of grip strength and walking speed before the intervention than PA group. These differences disappeared at the end of the 2 years. Control group presented worse values of muscle strength and 30-s chair stand. PA group maintained their functional capacity after 2 years. CONCLUSIONS: elderly subjects living in nursing homes can maintain their physical fitness and functional capacity performing with physical exercises 2489 Board #236 May 29, 9:30 AM - 11:00 AM Effect Of Recreational Soccer Practice On Cardiac Vagal Reactivation Fabrício Vasconcellos 1 , André Seabra 2 , Felipe Cunha 3 , Paulo Farinatti 3 . 1 Faculty of Sport, University of Porto, Porto, Portugal / State University of Rio de Janeiro, Brazil, Rio de Janeiro, Brazil. 2 Faculty of Sport, University of Porto, Porto, Portugal, Porto, Portugal. 3 State University of Rio de Janeiro, Brazil, Rio de Janeiro, Brazil.

On the other hand, physical activity may help preventing this autonomic unbalance. PURPOSE: To investigate the effect of a recreational soccer program (RSP) upon cardiac vagal reactivation in obese adolescents. METHODS: 20 obese adolescents (7 girls; Body Mass Index Z-score > 2; age= 14.3 ±1.2 yrs) were assigned into recreational soccer (RSP, n=10) and control (CG, n=10) groups. The RSP group participated in a 12-week RSP program (3 times/wk) consisting of 10 min warm-up, followed by 50-80 min of soccer in a reduced pitch area with an average intensity of 80% maximal heart rate. Cardiac vagal reactivation was assessed each 30 seconds after maximal CPX, using the rMSSD index from heart variability. RESULTS: At baseline, no difference between groups was found for the rMSSD after CPX. After intervention, the increase of rMSSD in RSP was greater over CG at all assessments (30s: ΔRSP= 6.7 vs. ΔCG= 0.3, P= 0.05; 60s: ΔRSP= 7.3 vs. ΔCG= 0.7, P= 0.05; 90s: ΔRSP= 8.4 vs. ΔCG= -0.5, P= 0.04; 120s: ΔRSP= 10.5 vs. ΔCG= 2.5, P= 0.05; 150s: ΔRSP= 13.9 vs. ΔCG= 2.8, P= 0.03; 180s: ΔRSP= 15.4 vs. ΔCG= 1.6, P= 0.04; 210s: ΔRSP= 14.3 vs. ΔCG= 1.9, P= 0.03; 240s: ΔRSP= 16.5 vs. ΔCG= 2.7, P= 0.01; 270s: ΔRSP= 16.8 vs. ΔCG= 4.2, P= 0.05; 300s: ΔRSP= 20.1 vs. ΔCG= 0.1, P= 0.01). CONCLUSION: A 12-week recreational soccer intervention performed 3 times/wk was able to improve the cardiac vagal reactivation in obese adolescents.
