Despite well-known benefits of physical activity for older adults, most older adults remain significantly underactive. The purpose of this study was to examine the effects of an inclusive, choice-based physical activity promotion program to increase lifetime physical activity levels of seniors on physical activity & health-related quality of life outcomes in older adults. The physical activity promotion program guided participants to choose activities that took into account their health, preferences, and abilities. It offered information on ways for them to exercise safely, motivate themselves, overcome barriers, and develop a balanced exercise regimen. A six-month comparison-group trial was conducted with older adults in community senior center. Changes in self-reported physical activity & health-related quality of life(SF-36) by group & within group were evaluated using t-test. Of 30 subjects, 22(73%) completed the trial. Subjects were aged 63 to 75 years(mean=$68.36{\pm}4.02$); 86% were female. The intervention group increased estimated caloric expenditure by 1975 calories/week in moderate intensity activities(MET${\geq}3.0$; p=.008), and by 2312 calories/week in physical activities of any intensity(p=.005). Between-group analyses showed that the changes were significantly different in both measures(p=0.17; p=032). The intervention group also significantly better scores on general health perception(p=.031) & vitality(p=.002). Individually tailored programs to encourage lifestyle changes in seniors may be effective and applicable to health care and community settings.

Purpose: The purpose of this study was to analyze the relationship between physical activity and energy drinks consumption in Korean Adolescents. Methods: This study was a secondary data analysis using statistics from the 2017(13th) Korea Youth Risk Behavior Web-based Survey. The variables used in the study were physical activity, energy drinks consumption and socio-demographic characteristics such as gender, academic achievement, household economic status and weekly allowance. The data were analyzed by $x^2$ test and multinominal logistic regression and the results were presented in percentage. Results: As the number of days engaging in moderate and vigorous physical activities increased, the response that they consume energy drinks 'more than 5 times a week' also increased. The subjects who participated in a 'moderate' or 'high' level of moderate physical activity consumed 1.4 times more energy drinks than those who do not participate in physical activity. And the subjects who engaged in a 'low' or 'moderate' level of vigorous physical activity consumed about 1.3 times more energy drinks than those who don't work out. Conclusion: As the level and intensity of physical activity increased, the number and frequency of energy drinks consumption increased. The results of this study can be used as basic data for intervention programs to reduce energy drinks consumption and promote proper physical activity.

Purpose: The talk test (TT) is an alternative, self-reported method for prescribing and guiding exercise training in both healthy adults and patients with cardiovascular and pulmonary diseases. This study examined whether the TT is a valid tool for evaluating the exercise intensity during two different types of aerobic activity on a treadmill or stationary bicycle in a healthy population. Methods: A total of ten subjects (six males and four females) who had no medical history related to musculoskeletal, cardiovascular, and pulmonary disorders were enrolled in this study. They were evaluated using the TT, which consisted of three-level of difficulties demanding cardiac loads while performing aerobic activities on a treadmill and bicycle ergometer across two consecutive days in a counterbalanced manner. During the activities, the psychophysiological response markers were collected in terms of the heart rate, oxygen saturation, rating of perceived exertion, and metabolic equivalents. Results: Statistical analyses revealed a significant difference in the between-subject variance regarding the TT level effect (p<0.05). On the other hand, no significant findings were detected on the between-group variance(p>0.05) and the TT level×group interaction (p>0.05). The independent t-test indicated no significant differences in heart rate, oxygen saturation, rating of perceived exertion, and metabolic equivalents at any levels of the TT in the two groups. The TT showed a strong correlation with the rating of perceived exertion. Conclusion: This study showed that the TT is a valid and alternative tool for evaluating the aerobic exercise intensity in a healthy population. In addition, differences in the psychophysiological response markers between two aerobic activities, treadmill and bicycle ergometer, were detected in the same exercise intensity scaled with the TT. The TT can be used to evaluate and prescribe the exercise intensity of aerobic activity in cardiovascular and pulmonary physical therapy.

Objectives: The purpose of this study was to compare the physical activity level (PAL), the physical activity pattern and the energy expenditure in male and female elementary school soccer players using the accelerometer and the physical activity diary. Methods: Twenty-five (male 11, female 14) elementary school soccer players (9-12 years) participated in this study. During their daily activities, they wore an accelerometer for seven days (five weekdays and two weekend days) and completed the physical activity diary for three days (two weekdays and one weekend day). PAL was calculated by using the physical activity diary and three equations (Pate Preschool, Freedson Children, and Freedson) were used to calculate the intensity of physical activity and energy expenditure from the counts of accelerometer. Results: The average of physical activity by day of the week, CPM (Counts Per Minute) and METs (Metabolic Equivalents) were significantly higher in males ($723.3{\pm}149.2CPM$, $2.07{\pm}0.18METs$) compared to females ($505.6{\pm}119.9CPM$, $1.79{\pm}0.20METs$), but there was no significant difference in PAEE (Physical Activity Energy Expenditure) between the two groups (males: $15.5{\pm}9.1kcal/day$, females: $11.5{\pm}6.0kcal/day$). During weekdays, physical activity intensity was significantly higher in males compared to females at lunch time and training time than at other times. In both genders, the PAL was higher during weekdays (males 1.98, females 1.89) compared to weekend (males 1.62, females 1.61) (p<0.05). Conclusions: Our study observations suggest the necessity to develop an accelerometer equation for accurately evaluating the physical activity of elementary school athletes.

Purpose: This study was to investigate factors influencing the Framingham risk score-Coronary heart disease (FRS-CHD) according to gender and body mass index (BMI) of adults who participated in the 5th Korea National Health and Nutrition Examination Survey (KNHANES V-3). Methods: This study used a cross-sectional design with secondary analysis with KNHANES V-3. The FRS-CHD scores were measured with ages, sex, blood pressure, cholesterol, high density lipoprotein, smoking, and diabetes mellitus. With demographic characteristics, family history of ischemic heart disease, types (intensity) and days of physical activities, perceived stress, drinking, menopause (in female), and BMI scores were measured. The data were analyzed with descriptive statistics, Pearson's correlation coefficients, and multiple regressions. Results: FRS-CHD was significantly associated with types (intensity) and days of physical activities, educational level, occupation, and marital status, explaining 19.1~76.8% of the variance in men. FRS-CHD was significantly associated with types (intensity) and days of physical activities, menopause, and education level, explaining 55.0~59.5% of the variance in women. Conclusion: Factors influencing FRS-CHD were significantly different according to gender and BMI. To reduce the risk of coronary artery disease, it is necessary to develop gender-specific physical activity programs according to BMI.

Purpose: Hypertension tends to increase after the age of 65. Proper hypertension management requires physical activities such as habitual activities and exercise. However. it is reported that many elders do not have regular physical activities. This study was to identify physical activity patterns and blood pressure according to physical activity in the elderly with hypertension. Methods: This study assessed physical activity frequency, amount, type during the latest one week, and blood pressure and BMI. The subjects were 53 elders aged over 65 years. Collected data were analyzed through descriptive statistics, $x^2-test$, and logistic regression analysis using SPSS 12.0. Results: It was found that most of the subjects had not been participating in regular physical activities. The most frequent physical activity patterns were walking and home activity at a low or moderate intensity. The elderly who met the normal hypertension and pre-hypertension criteria involved significantly more regular physical activities. Conclusion: This study suggested that regular participation in physical activities should be recommended for elders in order to optimize the state of their blood pressure.

Background: Identification of reliable predictors of leisure time physical activity (LTPA) will enable healthcare providers to intervene and change the patterns of LTPA in the population to improve community health. Objectives: The objectives of this study were to determine prevalence and pattern of LTPA among adult Saudis aged 18-65 years, and to define the socio-demographic determinants that correlate with LTPA in Al-Hassa, Saudi Arabia. Subjects and Methods: A cross-sectional study of 2176 adult Saudis attending urban and rural primary health care centers were selected using a multistage proportionate sampling method. Participants were personally interviewed to gather information regarding socio-demographics, physical activity pattern using the Global Physical Activity Questionnaire (GPAQ). Physical activity (PA) in each domain was expressed in metabolic equivalents (METs). Results: The median total METs minutes/week for LTPA for both genders was 256, higher for men (636 METs minutes/week) compared to women (249METs minutes/week). Overall, only 19.8% of the total PA was derived from LTPA. Of the sampled population 50.0% reported doing no leisure activity. Using the cut off of 600 METs-minutes/day or 150 minutes of moderate intensity over 5 or more days/week, only 21.0% of the included sample were considered as being sufficiently active and 10.4% were in the high active category with beneficial health effects. Multivariate regression analysis showed that male, younger age (<35 years), absence of chronic disease conditions and moderate level of total PA were significant predictors for being active in the LTPA domain. Conclusion: The prevalence and intensity of LTPA among the included sample demonstrated low levels. Nearly 80% of the included sample population did not achieve the recommended LTPA level with beneficial health effects. Female gender, urban residence and associated chronic diseases correlated with a low LTPA.

본 연구의 목적은 2014년 조사되어진 제 6기 2차 국민건강영양조사 자료를 바탕으로 연령별 신체활동에 따른 대사성질환과의 관계를 파악하여 연령별 신체활동에 따른 대사성질환과의 관련성을 규명하여 예방적 기초자료를 제공하기 위한 연구이다. 본 연구는 제 6기 2차(2014) 국민건강영양조사의 자료를 이용하여 수행되었다. 정상군의 382명과 대사질환군의 1,525명을 총 9,701명의 설문 응답자 중 관련 자료가 없는 2,506명을 제외하고 총 7,295명을 분석했다. 본 연구에서 신체활동은 국제신체활동 설문지 (IPAQ)를 기반으로 재분류 되었다. 대사증후군의 정의는 2004년 개정 된 NCEP-ATP III에 근거하여 다음과 같은 결론을 얻었다. 연령에 따른 대사성질환과 신체활동과의 관계에서 10~29세 정상군과 50~69세의 대사질환군에서 혈색소, 적혈구용적, 크리아티닌의 수치는 고강도 신체활동이 수행되었을 때 증가했고 저강도 신체활동을 수행되었을 때 감소했다. 30~49세의 정상군과 대사질환군에서 고밀도 지단백 콜레스테롤 수치는 고강도 신체활동이 수행되었을 때 증가했지만, 저강도 신체활동이 수행되었을 때 감소하였다. 따라서 연령과 운동강도가 고밀도 지단백 콜레스테롤 수치에 미치는 영향을 조사하였다. 결과는 정상군에서 연령과 운동강도에 따라 고밀도 지단백 콜레스테롤 수치에 차이는 없었지만 대사질환군에서는 연령에 따라 고밀도 지단백 콜레스테롤 수치가 감소하였고 운동강도에 따라 증가하였다. 종합하면, 본 연구의 결과는 대사질환군에서 고밀도 지단백 콜레스테롤 수치는 고강도 신체활동에서 긍정적인 효과를 나타내고 연령은 부정적인 효과를 나타냈다. 이러한 결과는 우리가 신체활동과 연령에 따라 대사성질환을 더 잘 이해하는데 도움이 될 수 있다.
