Limited research has shown that athletic youth engage in better nutrition practices than non-athletes. However, most research has examined elite athlete nutrition practices, the female athlete triad, or sports that emphasize leanness. Furthermore, little or no research has compared nutrition behaviors in low-income children based on their level of sports participation. PURPOSE: To examine the differences among nutrition intakes and attitudes of athlete and non-athlete, low-income 3rd-5th grade students. METHODS: A sample of 211 students (mean age 9.7±0.9 years; 43.1% males) completed a two-part survey, including modules measuring daily frequency of intakes from food groups, frequency of meals, breakfast, snacks, and fast food consumption, and attitudes toward F and V consumption. Students were grouped into “no sports” (NS), “one sport” (OS) and “multiple sports” (MS). Kruskal-Wallis H tests were used to determine differences in consumption and attitudes between groups. Significance was set at p<0.05. RESULTS: Approximately 70% of youth participated in at least one sport, with the distribution for sport groups being 30.8% (NS), 29.4% (OS), and 39.8% (MS). Significant group differences were found for whole grain breads (WGB; χ2= 8.209, p = 0.016), total V (χ2 = 17.072, p<0.001), and total F (χ2 = 10.603, p = 0.005). Post hoc tests showed MS > NS for WGB (χ2 = -24.128, p = 0.022), OS>NS and MS>NS for V (χ2 = -27.933, p = 0.020; χ2 = -38.934, p<0.000) and MS>NS for F (χ2 = -29.990, p = 0.007). Significant group differences were also found for beliefs toward F/V consumption increasing strength (χ2 =10.937, p = 0.004) and providing more energy (χ2 = 7.456, p = 0.024). Post hoc test showed MS>NS and MS>OS (χ2 = -23.860, p = 0.018, χ2 = 25.061, p = 0.013) for strength and MS>NS (χ2 = -20.223, p = 0.024) for more energy, respectively. No significant differences were found for other nutrition variables. CONCLUSIONS: Low-income MS youth reported better nutrition behaviors than OS and NS youth and had stronger beliefs about potential health benefits of F/V consumption. These trends are similar to national data related to athlete nutrition behaviors.

Savas, Jeffrey B. Taylor, Sara L. Arena. High Point University, High Point, NC. (No relationships reported) As videogames become more interactive, it has been a growing curiosity if they could be used to improve physical function. However, it remains unclear if game performance is related to aspects of physical function. In particular, the Xbox 360 Kinect utilizes human movement commonly used in activities of daily living to control games and could potentially be used to assess or improve physical function. PURPOSE: To examine the relationship between game performance on the Xbox 360 Kinect and physical function in young adults. METHODS: There were 14 participants: 8 females and 6 males (mean + s.d. age: 20.4+1.1 years; height: 168.9+9.1 cm; mass: 69.4+12.8 kg). Each subject played Xbox Kinect Adventures!, which included Reflex Ridge, Space Pop, and 20,000 Leaks. Physical function measures included measures of lower limb strength, balance, and reaction time. Knee extensor, knee flexor, hip extensor, and hip flexor strength of the dominant limb was assessed with a handheld dynamometer on the dominant limb. Reaction time (motor, visual, physical) was assessed by a DynaVision D2TM on the dominant upper limb. Balance was quantified by the center of pressure (COP) range and mean COP speed in the AP and ML directions while standing with eyes closed for 30 seconds. RESULTS: Knee flexor, knee extensor, and hip extensor strength were all positively correlated with the scores in Reflex Ridge (r=0.7746, 0.6573, 0.6234 and p=0.0011, 0.0106, 0.0172, respectively). Motor (r=-0.698, p=0.006) and physical (r=-0.662, p=0.010) reaction times were both negatively correlated with the scores in Space Pop. Motor (r=-0.679, p=0.008) and physical (r=-0.626, p=0.017) reaction times were also negatively correlated with the scores in 20,000 Leaks. Balance measures were not correlated with game performance. CONCLUSIONS: Individuals who had greater knee flexor, knee extensor, and hip extensor strength and faster motor and physical reaction times tended to score higher on the video games. While these results indicate that game scores are significantly correlated to measures of physical function in young, health individuals, future research should focus on applying this technology to improving physical function in older adults. 2726 Board #249 June 3, 9:30 AM - 11:00 AM Effects Of Using Elastic Bands On Strength And Muscle Mass In Well-trained Young Men Phil Page, FACSM1, Nicole L.

Rogers, FACSM2. 1Louisiana State University, Baton Rouge, LA. 2Wichita State University, Wichita, KS. 3 University of Valencia, Valencia, Spain. (No relationships reported) There is a lack of information regarding the efficacy of using elastic bands (EB) to increase strength and fat free mass (FFM) in the upper extremities of young well-trained men. PURPOSE: To assess strength and muscle adaptations in the upper extremities of young well-trained men after a short-term resistance program using EB versus traditional weight devices. METHODS: 14 well-trained men were randomly divided into two groups: 1) EB group (EBG), 22.1 ±3.5yr, 12.8 ± 4.6% fat mass; and 2) weight Machine and Free Weight Group (MFWG), 21.2 ± 2.6yr, 12.7 ± 7.1% fat mass. An 11 week resistance-training program of 2-sessions-wk was performed. During the first 5 weeks, 6 exercises of 5 sets with 10 maximum repetitions (RM) and 60-90 sec of recovery time between exercises were performed. During weeks 6-11, 12 exercises of 5 sets with 8RM were performed in supersets with 90 sec of rest time between superssets. Subjects did not modify their usual diet habits. Pre-post training measurements were performed for arm FFM with a dual-energy X-ray absorptiometer and for elbow flexion peak power (PP) using an isokinetic device. Three nonparametric tests were performed assuming a p-value less than 0.05 (Wilcoxon test for paired samples, Kruskal-Wallis test and Mann-Whitney U test for 2 samples using the Bonferroni correction coefficient when there were differences between groups). RESULTS: EBG increased (p<0.05) FFM by 3.6% and PP by 6.46%. MFWG increased (p<0.05) FFM by 3.2% and PP by 2.9%. There were no differences between groups. CONCLUSIONS: It is possible to improve PP and FFM in well-trained recreational men using EB alone during a short-term resistance program. Furthermore, improvements from EB training are similar to those of traditional weight devices. More studies are needed regarding the effects of EB on maximal voluntary strength in this population. 764 Copyright © 2016 by the American College of Sports Medicine.
