위치정보 표시 및 심박수를 이용한 운동강도 표시 앱을 개발하는 주요 목적은 개인의 건강 상태를 관리하고 개선하기 위함이다. 건강관리의 가장 기본적인 수단은 운동이다. 운동 중에서도 유산소 운동은 체력을 증가시키고 몸무게도 줄일 수 있는 등 가장 효과적인 운동이면서도, 누구나 큰 준비 없이 마음만 먹으면 할 수 있는 가장 기본적인 운동이라고 생각했다. 유산소 운동을 할 때 위치정보를 표시하고 심박수를 측정하여 운동강도를 표시해준다면 운동에 큰 도움이 될 것으로 생각했다. 위치정보 표시 및 심박수 센서를 이용한 운동강도 표시 앱으로 심박수, 이동 거리 등을 추적하고 기록하며, 이를 통해 심박수 상태를 확인하고 운동강도를 조절함으로써 효과적으로 운동할 수 있을 것으로 예상된다. 또한 reCaptcha를 이용하여 사람과 악성봇을 구별 가능하게 하여 보안성을 높였다.

This study is to evaluate the availability of cardiorespiratory fitness measurement by 20 m shuttle run test based upon energy contribution rates of elite athletes in different sports type. Sixty-seven elite athletes attending K national university participated in this study. They were divided by three groups based upon sports type, composed of Anaerobic Group (sprint, jumps, weightlifting, throw; n=35), Aerobic Group (medium-long distance; n=9), and Combat Sport Group (judo; n=23). 20 m shuttle run test was conducted by Leger et al.(1982) method and calculating acceleration using measured shuttle run repetitions was conducted by Brewer et al.(1988) method. To test the usefulness of VO₂max, graded exercise treadmill test was conducted and standing long jump and 50 m run were measured as power fitness factors. Z-jump was used for measuring power, agility, and muscular endurance. Standing long jump and 50 m run of Anaerobic Group (AnG) was significantly higher than that of Aerobic Group (AeG) and Combat Sport Group (CG) (p<0.05). However, Z-jump of CG was significantly higher than that of AnG and AeG(p<.05). There was a higher correlation of 20 m shuttle run test and VO₂max in AnG(r= 0.577, p<.0001) and CG(r= 0.760, p<.0001). Otherwise, there was a low correlation of 20 m shuttle run test and VO₂max in AeG. There was no significant group difference to test the availability of 20 m shuttle run test and there was a reduced error when converting 20 m shuttle run results into VO₂max. This study examined the usefulness of 20 m shuttle run test by converting 20 m shuttle run repetition results into VO₂max calculation, which showed reduced error. Therefore, this study confirmed that it would be needed to convert 20 m shuttle run results into VO₂max for universal and practical use in the field without dividing sports type.

This study was to designed to investigate the effects of nutrition education and exercise program for overweight or obese female adults, and also emphasize the necessity of a proper nutrition education. The anthropometric characteristics, nutritional intake, eating habit, and hematological index, physical examination were measured before and after program. Considering the time schedule of the subjects, the exercise program was divided into 3 sessions (morning, afternoon, and evening) and the subjects performed swimming and weight training for 4 weeks. The subjects were overweight or obese women, with an average age and height of each 46.1 and 156.3 cm. The weight and BMI were decreased significantly after nutrition education and exercise program. The back region of front arm (p<0.001), infrascapular region (p<0.001), body fat (p<0.001) were significantly decreased, and grasping power (p<0.01), back muscle power (p<0.001) were significantly increased after nutritional and exercise program. Total triglyceride level and fasting blood glucose (p<0.001) were decreased significantly after program. The intakes of vitamin D and vitamin $B_1$ were significantly changed after nutrition and exercise program. As for eating behavior and nutritional knowledge evaluation after program, the average score increased significantly (p<0.001). The results of this study show that this nutrition and exercise program can be an effective approach to improve their hematological index and nutritional and health status.

The aim of the present study was to compare the strength, balance, and flexibility across two age groups (older adults vs. young adults). The isokinetic muscle function, ankle ROM, trunk forward flexibility, stability, and antropometric data for the elderly and 46 university students were collected. The results indicated that male older adults possessed relatively low flexibility (2.97cm) among the groups and showed better stability in the right foot than in the left foot and $35^{\circ}$ of plantar flexion ROM, which was not in the normal range. Their peak strength at the knee joint was below 50% of their counterpart. They revealed a hamstring deficit of 18.55%, ankle eversion deficit of 23.08%, and ankle inversion deficit of 19.19%. The results indicated that female older adults possessed comparable flexibility compared to female young adults. The reciprocal muscle strength ratio of both knees was under 50%, and the deficit was 14.32% (extension) and 19.73% (flexion). The ankle plantar flexion peak torque was approximately 62% (left) and 73% (right) of WS's. The ankle dorsi flexion deficit was 25.05% and the plantar flexion was 26.86%. The eversion deficit was 19.97% and the inversion was 21.09%. These results will be significant in establishing an elderly fitness enhancement program and policy.

This study was conducted to compare physical fitness, self-esteem, organizational commitment and transformational leadership among non-smoker and smoker ROTC cadets. This study used 425 questionnaires from male grade 3 and 4 ROTC cadets of 12 universities located in P city and G-do. Data were collected from May 1 to June 23, 2017. The data were analyzed by SPSS/WIN 23.0 using a ${\chi}^2-test$, independent t-test, and Pearson's correlation coefficient. Running 3km (t=3.26, p=0.046), self-esteem (t=1.06, p=0.003), organizational commitment (t=2.57, p<0.001) and transformational leadership (t=3.98, p<0.001) were significantly lower in the smoking group than the non-smoking group. There was a positive correlation between self-esteem, organizational commitment, and transformational leadership in both non-smokers and smokers. Therefore, to practice smoking cessation for the health promotion of ROTC cadets smokers, it is necessary to develop an effective education and intervention program that can enhance self-esteem, organizational commitment and transformational leadership.
