Childhood obesity has more than doubled in children and adolescents in the last decade. Obese youth are more likely to have risk factors for cardiovascular disease and type 2 diabetes such as high cholesterol, high blood pressure, insulin resistance, and metabolic syndrome. There is no single or simple solution to the childhood obesity epidemic, but to learn that obesity is closely related to lifestyle factors including poor fitness and physical inactivity as well as prolonged sitting time in conjunction with westernized dietary habits. In addition to a healthy and balanced diet, promotion of physical activity combined with carefully supervised resistance exercise training, and reduced screen time is a primary recommendation for the prevention and treatment of obesity in children and adolescents. This review provides evidence based data to support this multiple-step physical activity strategy as the most effective and preventive means against childhood obesity.

A tangible sports game is an exercise game that uses sensors or cameras to track the user's body movements and to feel a sense of reality. Recently, VR indoor sports room systems installed to utilize tangible sports game for physical activity in schools. However, these systems primarily use screen-touch user interaction. In this research, we developed a V-Catch Vision system that uses AI image recognition technology to enable tracking of user movements in three-dimensional space rather than two-dimensional wall touch interaction. We also conducted a usability evaluation experiment to investigate the exercise effects of this system. We tried to evaluate quantitative exercise effects by measuring blood oxygen saturation level, the real-time ECG heart rate variability, and user body movement and angle change of Kinect skeleton. The experiment result showed that there was a statistically significant increase in heart rate and an increase in the amount of body movement when using the V-Catch Vision system. In the subjective evaluation, most subjects found the exercise using this system fun and satisfactory.

The present study aimed to identify the effects of the trunk stability exercise on functional movement, dynamic balance, and trunk stability in patients with chronic low back pain, and to compare the difference among yoga exercise, pilates exercise and core exercise. Forty-three patients with chronic low back pain were divided into three groups; 15 yoga groups, 15 pilates groups, and 13 core exercise groups. All subjects were tested the Functional movement, dynamic balance, and trunk stability using Functional Movement Screen (FMS), Lower Quater Y-Balance Test (YBT-LQ) and Trunk Stability Test (TST), respectively, and after each 8-week exercise program was applied, all variables were retested. After exercising during 8 weeks, FMS, YBT-LQ and TST scores of all three groups were significantly improved, compared to before, but there were no interaction effect among three groups depending on application of exercise program. These results showed that yoga, pilates and core exercise help to improve functional movement, dynamic balance and trunk stability in adults with chronic low back pain.

The purpose of this study was to demonstrate the effects of 8weeks Kettlebell training on the FMS and Balance in Middle school baseball player. Fourteen middle school baseball players were randomly assigned to a kettlebell group (n=8) and a control group (n=6), and kettlebell training was applied twice a week for 60 minutes. And the FMS, Y-balance test and static and dynamic balance test using smart shoes were tested before and after kettlebell training. Repeated two-way ANOVA measures was performed both before and after the exercise to verify the effect of kettlebell training. Also, if there was an interaction between time and group, a paired sample t-test was performed for each group. As a results of the study, FMS score showed a significant difference in IL (Inline Lunge) and TS(Total Score), and there was no significant difference in other variables of FMS. The YBT score showed a significant difference in all YBT variables except for the left AT. And the balance test using smart shoes, there was no significant interaction effect between group and period in all variables. In conclusion, it was found that the application of kettlebell training in middle school baseball players had an effects on the FMS and YBT scores related to functional movement and functional balance, but it did not affect the static/dynamic balance test using smart shoes evaluated by the foot pressure method. It seems that the results of this study can be provided as basic data necessary for planning a training program for middle school baseball players.

A low-cost and flexible potassium ion (K⁺) sensor was fabricated through a screen-printed process. Uniform and conformal coating of conductive inks was verified by scanning electron microscopy and optical microscopy measurements. The K⁺-sensors showed a high sensitivity, fast response time, and low detection limit. The sensitivity of K⁺-sensor was similar to that of both mechanically normal and bent states. The K⁺-sensor exhibited a good reproducibility with no hysteresis effect and excellent long term stability. In addition, the K⁺-sensor showed an excellent selectivity for K⁺ concentrations in the presence of other interfering cation ions. Successful measurements of K⁺ concentrations in sports drink samples were demonstrated by comparing K⁺ concentration values from K⁺-sensor to those of using a commercial K⁺-meter.

Objective: Training-related injuries and attrition put an additional burden on police and military institutions. Preventing and minimizing musculoskeletal injuries is the primary concern of the Abu Dhabi Police. Therefore, this study aimed to evaluate the correlation between functional movement screen, lower-limb strength, Y-balance test, grip strength and vertical jump and the incidence of musculoskeletal injuries among Abu Dhabi police recruits. Design: Observational analytical study. Methods: An observational study was conducted on 400 male police recruits of Abu Dhabi Police Academy. Physical performance was assessed before the 16-weeks basic police training. Spearman's correlation evaluated the correlation between the performance parameters and the outcome measures and logistic regression predicted the risk factors associated with musculoskeletal injuries. Results: 149 (34.4%) participants reported at least one injury during the basic police training. Comparison between injured and non-injured participants showed significant difference in mean right Y-balance, back-leg-chest dynamometer, and vertical jump (p=0.02, p=0.02, and p=0.04, respectively). Spearman's correlation showed a significant negative correlation between risk of injury and back-leg-chest dynamometer and right Y balance (ρ= -0.11, p=0.03). Logistic regression showed that back-leg-chest dynamometer and right Y balance were significant predictors of injury (p =.036 and p=0.037; Odds ratio=0.96; 95% CI (0.92, 0.99) and Odds ratio=0.99; 95% CI (0.98,0.99). Conclusions: Our findings suggest functional movement screen and grip strength may not independently predict injury rates, balance and lower-limb strength needs to be considered in injury prevention strategies to reduce musculoskeletal injuries.

Lately the usage of multimedia equipment with small LCD displays is rapidly increasing. Although many people use devices like cell phone and PDA, videos intended for TV or HDTV are sent to these mobile devices. Therefore, situation where it is hard for the user to view the desired scenes are growing more frequent. Currently, most services simply reduce the size of the content to fit the screen when they offer it for mobile devices. However, especially with sports broadcasts, there are many areas that cannot be seen very well because it was simply reduced in size. We are suggesting new motion how to let the user choose an area of interest based on Cognitive lattice. And present then sending it to the user in a way based on Focus Of Choice that fits the device.
