Purpose An increase in the number of fitness apps across the world is a testament to the growing interest in health. As focus on medical services shifted from treatment to prevention, this type of app plays an essential role in promoting one's health and exercise management. Yet little has been known about practical effects of fitness apps in existing literature thus this study searches for factors that affect daily use of fitness apps and examine the relationship between app usage and exercise patterns. Design/methodology/approach This study surveyed people who used Cashwalk, the pedometer app for a minimum of a week to analyze reasons why they used the app. Particpants' exercise patterns were also recorded. By examining survey results of fitness app users and developing a research model based on the Customer Value Theory, this study provides real-life factors to the fitness and smart health care industry that will adopt a proactive lifestyle pattern. Findings Empirical analysis proved properties such as the complexity of fitness apps, monetary rewards, exercise monitoring and the enjoyment of using fitness apps contribute to using fitness apps on a daily basis. Furthermore, more daily use of fitness apps was shown to have a greater impact on exercise. This study also confirmed that social comparison does not affect the daily use of fitness apps and the amount of exercise, and the habitual walking was proved to directly affect the amount of exercise.

Modern technology has lessened the physical demand of every activities. Thus, physical inactivity has led to a rise in ‘Hypokinetic diseases’. The prefix, hypo, means lack of and kinetic refers to movement. Individuals who do not exercise regularly are at greater risk of developing hypokinetic diseases such as coronary heart disease, hypertension, hyperlipidemia, obesity, musculoskeletal disease. Systematic exercise program defenses development of hypokinetic diseases. Exercise program bases on basic physical fitness test. The physical fitness evaluation is used to degree of Wellness of the individuals. It includes the evaluation of Health-Related Physical Fitness -musclular strength, muscular endurance, flexibility, cardiorespiratory endurance, body composition - and skill or sports related fitness -agility, balance, coordination, reaction time, speed. In present study, the authors investigated health-related physical fitness test result and questionnaire for 133 male and 71 female from Jannuary 16 to March 15, 1997. The purpose of this study is to observe relationship health related physical fitness and self-perceived health status. The results are as follows. 1. There were statistically significant differences in BMI, grip strength, back strength, muscular endurance, cardiorespiratory endurance, and flexibility between male and female subjects. Flexibility is higher in female than male subject, but Others are higher in male than female subjects. 2. There were statistically significant differences in grip strength, muscular endurance between 30s, 40s, and 50s group In both gender subjects, and In cardiorespiratoryendurance between the groups especially in Female subjects. 3. For male subjects, flexibilitywas measured lower in group who classified low level in self-perceived health status than group of others. Also, for female, subjects, Muscular endurance ＆ flexibility were measured. 4. It was shown that grip strength, back strength, and muscular endurance were significantly lower in group who have chronic diseases than normal group for Male subjects. But, For female subjects, all the component were statistically insignificant results between normal and disease group. 5. Both male and female subjects, there were Positive correlation among grip strength, back strength, muscular endurance, cardiorespiratory endurance, and flexibility but, negative correlation for age. Therefore, health-related physical fitness is very important component for Heath Promotion ＆ Wellness. Physical Fitness test is valuable test in health evaluation, health management and health promotion, so available for hospital, sports center, community health center, industrial field, school etc.

The medical fitness of pilots is part of the civil aviation safety scenery. This study aimed to analyze the health problems occurring among Korean commercial pilots. Three data sources were used to identify the health problems: 7,574 aviation medical examination data, 5,400 sick leaves and 39 cases of a decrease in medical fitness during flight duty period and layover of Korean commercial pilots who have been working for K airline from Jan. 1, 2016 to Dec. 31, 2018. This study was retrospectively analyzed using SPSS 22 statistical program. Waiver of medical certificates was an average 11.9% of total issuance for 3 years, with a denial of 0.1%. The leading cause of denial of medical certificates was predominantly of cardiovascular cause (55.6%). Mild respiratory and digestive disease accounted for 82% of total sick prevalence and 68% of total sick days. The psychiatric and cardiovascular disease were ranked high according to the number of days lost per case. The most common cause of decrease in medical fitness during flight duty period was acute abdominal pain (36.4%) and musculoskeletal disorder (40%) when staying abroad. Aeromedical emphasis on minimizing cardiovascular risk remains appropriate. Major pilot health problems identified in this study should be considered in establishing pilot health promotion programs for aviation safety.
