The proposed system is composed of two parts, an AI physical fitness measurement part and an AI physical fitness management part. In the AI fitness measurement part, a guide to physical fitness measurement and accurate calculation of the measured value are performed through deep learning-based pose recognition. Based on these measurements, the AI fitness management part designs personalized exercise programs and provides them to dedicated smart applications. To guide the measurement posture, the posture of the subject to be measured is photographed through a webcam and the skeleton line is extracted. Next, the skeletal line of the learned preparation posture is compared with the extracted skeletal line to determine whether or not it is normal, and voice guidance is provided to maintain the normal posture.

The incidence of childhood obesity has increased dramatically. Childhood obesity is an increasing health problem because of its strong associations with chronic health problems in children and adults. These health problems significantly contribute to the development of common chronic diseases in later life, including hypertension, type2 diabetes, hyperinsulinemia, coronary heart disease, and other psychological disorders. So it is an important issue to prevent and treat obesity during childhood and adolescent. Diet and exercise are the cornerstones of treatment for obesity and related complications. For obese children, some clinical trials have shown improvement with diet, exercise, and /or behavioral interventions. Promising interventions for high-risk individuals, such as bariatric surgery and novel pharmacological agents, also require rigorous assessment with attention to long-term patient important outcomes. There are various pharmacological approaches to the treatment of obesity in the adolescent population some of which have FDA approval. In the article we discuss pharmacological approaches to guide the treatment of obesity in the pediatric population, including risks of treatment, monitoring of potential side effects.

Purpose: This study examined the effects of a paraffin treatment with exercise on the muscle strength and fatigue of the hand according to the use of smartphones. Methods: The measurement subjects were 30 healthy males in their 20s who were divided randomly into the control and paraffin treatment groups. A typing exercise using a smartphone was performed. The pinch grip force was measured to evaluate the muscle strength of the thumb, and muscle fatigue analysis using electromyography was performed to analyze muscle fatigue. Results: The functional changes to the arm and the fatigue of the hand through the use of a smartphone were examined to determine the effects of the paraffin treatment. The dominant hand-pinch grip force test did not show a significant difference, but the non-dominant hand-pinch grip force test showed a significant difference between the groups (p=0.030). In the dominant hand fatigue test, there was a significant difference between the groups (p=0.037). In the non-dominant hand, there was a significant difference between time (p=0.012) and the groups (p<0.001). Conclusion: The effects of paraffin intervention on the hand muscle strength and fatigue due to repeated use of the smartphone were confirmed. These results can be used as a basis for clinical use and can be a guide for the correct use of smartphones, which are essential in modern life.

Purpose: The objective of this study was to investigate the relationship between fatigue, sleep disturbance, and gestational stress in women during late stage of pregnancy. Methods: This study was conducted with 113 healthy pregnant women at gestational age greater than 27 weeks who were registered at community health centers and received prenatal care. A structured questionnaire regarding fatigue, sleep disturbance, and gestational stress was used. The data was analyzed using a t-test, an ANOVA, and Pearson correlation coefficients. Results: The subjects with unplanned pregnancies and irregular exercise patterns showed a higher level of fatigue than those with planned pregnancies and regular exercise patterns. Pregnant women with caffeine intake manifested higher levels of gestational stress and sleep disturbance than those without. The levels of sleep disturbance and gestational stress increased as the fatigue levels increased. The fatigue levels increased with increased levels of sleep disturbance. Conclusion: Planned pregnancy, regular exercise patterns, and caffeine intake were related with fatigue, sleep disturbance, and gestational stress in women during late stages of pregnancy. Fatigue, sleep disturbance, and gestational stress had close associations to each other. In the future, such results should guide development of nursing intervention programs for women in late stages of pregnancy.

Purpose: The primary purpose of this study was to investigate the effects of cervical stabilization exercise (CSE) on hamstring flexibility in patients with neck pain. A secondary purpose of this study was to investigate the effects of cervical range of motion (CROM) and craniovertebral angle (CVA). Methods: This study was a single-blind, randomized, comparative trial. Twenty patients were allocated into either the cranio-cervical flexion exercise (CCFE) group or the CSE group. Before and after the intervention, we measured straight leg raise (SLR), popliteal angle (PA), CROM, and CVA in the sitting and standing positions. Fisher's exact test, the Mann-Whitney test, and Wilcoxon's signed-rank test were used to analyze our data. Results: Both groups showed significant improvements in the value of SLR, PA, cervical extension, cervical rotation, and CVA in the standing position (both, p<.05) after intervention. However, only the CSE group showed significant improvements in cervical right lateral flexion (z=-2.209; p<.01) and cervical left lateral flexion (z=-2.537; p<.05) after intervention. The CSF group showed more significant improvements in SLR, PA, both cervical lateral flexions, and both cervical rotations than the CCFE group. Conclusions: The results of this study will guide future research in identifying the effectiveness of CSE. In conclusion, it can be inferred that CSE has a positive effect on SLR, PA, CROM, and CVA in the standing position in patients with chronic neck pain.

The purpose of this study was to investigate the effect of theratainment low extremity complex exercise using unstable surface on knee and static plantar pressure in patient with genu varum. 25 adult subjects were recruited and randomized into stable surface exercise group(SEG) and unstable surface exercise group(UEG). Subjects carried out complex exercise(elastic band exercise & squat exercise) for 40 minutes, 4 times per week for 5 weeks. The knee joint distance and Q-angle of all subjects measured, the foot pressure measured distribution on the front and rear of both foots during pre and post. The most outcome at post was significantly improved than the pre outcome in the both group(p<.05). The result of this study show that the low extremity complex exercise using unstable surface may be appropriate for improving structure of knee joint and static plantar pressure in patient with genu varum. This will enable the application of low extremity complex exercise using unstable surface in rehabilitation therapy of genu varum and it will help guide the selection of the therapist as one therapeutic basis.

This study aimed to investigate the relation between self-esteem and satisfaction. After gathering study subjects (exercise participants) and deciding the population in 2014 in Jeonbuk city area, convenience sampling method was used to analyze the date from 278 subjects. The retrieved questionnaire in the research was analyzed in Window SPSS version 21 statistical program. Frequency analysis, exploratory factor analysis, reliability analysis, and correlation analysis were used to find correlations between test values. Multiple regression analysis was used to find the effects of the test values. The study results are as follows. First, the exercise participants' positive self-esteem exhibited a positive relationship with competence, relatedness, and autonomy, which are sub factors of basic psychological needs satisfaction. Also, negative self-esteem had a negative relationship with competence, relatedness, and autonomy. Second, exercise participants' self-esteem had a positive effect on competence and autonomy in positive self-esteem and a negative effect on negative self-esteem. Relatedness had a positive effect in positive self-esteem but not in negative self-esteem. Thus it is necessary to increase positive self-esteem and make various exercise programs about basic psychological needs satisfaction of the exercise participants and strategic activity guide for exercise participants participating in exercise consistently.

Background: Unstable surface-based core training can significantly enhance core strength, but no studies have compared the effects of balance pad- and sling-assisted exercises. Objects: To study the effects of unstable surface-based balance pad- and sling-assisted core strength exercises on muscle activity. Methods: Twenty male students aged 20-25 years participated in this study. The effects of three types of core strength exercises, performed with a sling or balance pad, on the activities of three muscles, i.e., the right musculus obliquus externus abdominis (EO), right erector spinae (ES), and right gluteus maximus (GM), were examined. Results: 1) In the glute bridge exercise, the percentage of maximum voluntary contraction of the EO, ES, and GM were significantly different between the balance pad- and sling-assisted exercises. The relative contribution of the ES and GM activities to all muscle activity were not significantly different between the two training types, whereas that for EO showed a significant difference. 2) There was no significant difference in the percentage value of maximum voluntary contraction (%MVC) among the EO, ES, and GM during the "leg-lifting with flat support" exercise, and there were no significant difference in the relative contributions between the two training types. 3) In the "side bridge leg separation exercise", the %MVC of the ES, EO, and GM were significantly different between the two training types. Conclusion: Sling training for core muscles was generally better than balance pad assist training. The majority of physiotherapy patients require core training. Our results could guide physiotherapists in the choice of targeted exercises for these patients.
