  • This study was to examine on the respiratory variables, heart rate and muscle activity between the static recovery and dynamic recovery after progressive resistance exercise to maximal point. Subjects were 15 students enrolled in N University. All were tested two times (static recovery and dynamic recovery) and were requested to perform a walking on a treadmill after progressive resistance exercise to maximal point. Electromyography(EMG) was used to monitor the muscle activity(TA: Tibialis Anterior, MG: Medial Gastrocnemius) during gait. CPEX-1 was used to measure the respiratory variables and heart rate. The dynamic recovery group was shown the significant lower heart rate than that of static recovery group at during gait. Respiratory rate showed statistically a significant difference. Electromyography(RMS, root mean square) showed a non-significant difference. But the dynamic recovery group of muscle activity was found highly in TA and MG. This study indicated that the dynamic recovery method evidenced more faster than the static recovery method. And this type of dynamic rest by walking can be a help of recovery after exercise.

  • In search for a method of evaluating the cardiopulmonary function. 74 male and 33 female volunteers ages $18{\sim}25$ were subjected to this study The subjects walked on a treadmill at speed of 2,4,6 and 8km/hr with 0,5,10,15,20 and 25% grade of inclination, respectively, for a measurement of heart rate and oxygen-pulse. Heart rate was measured every 5 seconds at resting state and during walking by telemetric method using Heart Checker 108 System (Senoh Co., Japan). Oxygen concentration was measured by Douglas bag method collecting expired air for 5 minutes at rest, and for 2 minutes at the end of each walking exercise. Oxygen concentration in an expired air was analyzed with Orzat gas analyser and expressed in terms of STPD. Oxygen-pulse was defined as an amount of oxygen consumed at every heart at a cellular level. The followings were the results obtained from this study. 1. Mean values of oxygen-pulse at resting state was $3.1{\pm}0.11ml/beat$ in male and $2.5{\pm}0.87ml/beat$ in female, respectively. 2. Mean values of oxygen-pulse during treadmill walking were increased in proportion with the load of exercise, namely, the speed and grade of inclination, from minimum of 7.1ml/beat upto maximum of 18.2ml/beat in male and from minimum of 4.2ml/beat upto maximum of 12,7ml/beat in female. 3. Both linear and logarithmic regressional relationships between oxygen-pulse and speed of walking and grade of inclination were observed in both sexes. Predicted values of oxygen-pulse by logarithmic regressional formula on speed and on grade of inclination were better coincided with the measured values than those predicted by the linear regressional formula.

  • Purpose of this study is to analyze the changes in state anxiety, heart rate, and fall efficacy of the elderly through the handle height of walking assistant vehicle (WAV). The subjects were 32 elderlies. WAV was in the form of strollers, and it's handle height was set as 48% of a subject's total height. Also, it's height was divided into 48, 43, 38%. To measure the state anxiety, Korean State-Trait Anxiety Inventory was used and to measure the heart rate, Fitbit Charge 2 wrist heart rate monitor was used. To measure the fall efficacy, Fall Efficacy Scale-Korea was used. As the results of state anxiety and heart rate, the statistically significant increase showed continuously through the decrease of the handle height of WAV. As the results of fall efficacy, the statistically significant decrease showed continuously through the decrease of the handle height of WAV. In all of the post hoc test, the results of the state anxiety and fall efficacy showed significant difference among the each handle height of WAV and the results of the heart rate showed significant difference between the 48, 43% and 38% handle height of WAV. Thus, to decrease the state anxiety and heart rate and increase the fall efficacy of the elderly, the handle height of WAV should be properly positioned and considered to adjust to 48% of the user's total height.

  • This study was carried out to verify the accuracy of fitness tracking devices in monitoring heart rate and energy consumption and to contribute to the development of a forest exercise program that can recommend the intensity and amount of forest exercises based on personal health-related data and provide monitoring and feedback on forest exercises. Among several commercially available wearable devices, Fitbit was selected for the research, as it provides Open API and data collected by Fitbit can be utilized by third parties to develop programs. Fitbit provides users with various information collected during forest exercises including exercise time and distance, heart rate, energy consumption, as well as the altitude and slope of forests collected by GPS. However, in order to verify the usability of the heart rate and energy consumption data collected by Fitbit in forest, the accuracy of heart rate and energy consumption were verified by comparing the data collected by Fitbit and reference. In this study, 13 middle-aged women were participated, and it was found that the heart rate measured by Fitbit showed a very low error rate and high correlation with that measured by the reference. The energy consumption measured by Fitbit was not significantly different from that measured in the reference, but the error rate was slightly higher. However, there was high correlation between the results measured by Fibit and the reference, therefore, it can be concluded that Fitbit can be utilized in developing actual forest exercise programs.

  • There are many types of walking exercise. We have choice the way according to the walking exercise purpose. Nordic walking(NW) is one of walking types with nordic poles. Also, power walking(PW) has motion of large swing the arm in walking, and dumbbell walking(DW) way is walking with 3-pound dumbbell. This study compared the physiological response(heart rate, energy expenditure) of general walking(GW) to another types(nordic, power, and 3-pound hand weights walking way). Seven apparently male health volunteers between the ages 19 and 24 years participated. Each complete a treadmill test. The tests were assigned randomly, as submaximal walking trials on separate days. Each walking trial was conducted on a level treadmill, for 40 minutes(3-5mile/hour 5min warm-up, 6mile/hour speed for 15min walking and 7mile/hour speed for 15min Jogging exercise, and 5-3mile/hour cool down 5min), at an same pace. Heart rate in beats per minute(bpm), and energy expenditure in kcal per minute(kcal/min) were recorded each minute. Results between trials were compared using repeated measures analysis of variance and Tukey's post hoc tests. In slow walking, it was found that walking with 3-pound hand weight way resulted in and average of ($127.8{\pm}8.27bpm$) the highest score HR, Caloric expenditure($85.4{\pm}14.51kcal/min$), responses compared to regular walking way($117.4{\pm}7.27bpm$ and $70.4{\pm}10.99kcal/min$). Nordic walking way($121.4{\pm}11.74bpm$, and $77.0{\pm}16.83kcal/min$) is second, power walking way($118.5{\pm}9.98bpm$, and $68.7{\pm}20.62kcal/min$) is next. In fast walking, it was found that walking way with 3-pound hand weight resulted in and average of ($160.1{\pm}8.72bpm$) the highest score HR, caloric expenditure($126.1{\pm}13.86kcal/min$), responses compared to regular walking way($148.4{\pm}11.94bpm$, and $109.0{\pm}4.70kcal/min$). Nordic walking way($156.7{\pm}10.82bpm$, and $113.5{\pm}14.51kcal/min$) is second, power walking way($149.7{\pm}12.56bpm$, and $109.2{\pm}17.64kcal/min$) is next. Thus, it is the unavoidable conclusion that, comparing with general walking, 3-pound hand weight walking, nordic walking, and power walking methods have the advantage of high exercise intensity and energy expenditure to meet the purpose of performers without the problem. Furthermore, 3-pound hand weight walking ways were proved to be a useful aerobic exercise method as whole body that achieves high-energy efficiency. To this extent, 3-pound hand weight walking ways can be recommended as a continuous and regulative aerobic exercise for some people.

  • The aim of this paper is to develop and verify the system which can detect heart rate during exercise by using conductive fabric electrode and transportable measurement module. The experiment was performed under 4 conditions(resting, walking, jogging, running) and 18 subjects data are used. By using the ECG measurement system used in cardiac stress testing as reference value in order to verify the accuracy of the developed system, the relative error and correlation coefficient was calculated for each subject at every 3 seconds. The results have shown that the high correlation between the developed system and the reference system for detecting heart rate during exercise. Relative error and correlation coefficient are 2.27% and 0.9877, respectively. 7 subjects data are omitted in these calculations because of severe noises. Therefore, it is expected that this system could be used as a health monitoring system in ubiquitous environment in the future.

  • The aim of this study was to clarify the physiological and psychological effects of walking around and viewing a lake in a forest environment. The subjects included 11 male Japanese university students (age: $22.0{\pm}1.2$ years) who were randomly assigned to visit either a forest or an urban (control) setting. They were instructed to walk a predetermined 15-min course and to view the setting from a seated position for 15 min. Heart rate variability, heart rate, blood pressure, pulse rate, and salivary cortisol levels were measured to assess the subject's physiological responses to the environment. Four questionnaires (SD method, reports of "refreshed" feeling, POMS, and STAI) were administered to assess the subjects' psychological responses. It was found that walking around and viewing a lake in a forest environment can suppress sympathetic nerve activity, increase parasympathetic nerve activity, and decrease the heart rate, blood pressure, pulse rate, and cortisol levels. In addition, a forest environment can enhance the "comfortable," "soothing," "natural," and "refreshed" feelings, improve the mood state, and reduce anxiety. These results provide scientific evidence of the physiological and psychological effects of forest therapy.

  • Korean clothings are admired for their beauty and traditional value. On the other hand, many of Korean women complain of chest restriction. Korean skirts may give high garment pressure to the wearers because the Korean skirt-band do not resolve physical tensions in size or in stretch. This paper aims at the identification of the garment pressure caused by the Korean skirt-band and the cardiopulmonary change caused by garment pressure. The Korean skirt-band were made in 3 kinds of size, and 21 women were selected for wearing test. The garment pressure was measured in front, side, and back parts of the body. The measured cardiopulmonary parameters were vital capacity, respiratory rate, heart rate, and blood pressure. The results were as follows: 1. The smaller the size of the Korean skirt-band, the greater the garment pressure. The pressure during inspiration was significantly greater than the pressure during expiration. 2. The pressure in side part was the greatest of the three measurements and the pressure in back part was the smallest. 3. The small size of the Korean skirt-band revealed low vital capcity and great respiratory rate. 4. As the small size grement was dressed, the respiratory rate and the heart rate during walking and rest after walking were significantly high. 5. Subjects felt uncomfortable when they wore small sized garment.
