Purpose : We investigated the effects of horseback riding and horseback riding machine exercise on the serum lipid profile in elderly individuals. Methods : Our study included 30 healthy elderly individuals who were randomly assigned to 2 groups: the horseback riding and the horseback riding machine exercise group, with each group comprising 15 individuals. The riding exercise program was performed 25 times a week over 12 weeks. The repeated measures analysis of variance was used to determine changes in serum lipid profiles before and after exercise 6 and 12 weeks after exercise. Results : An intergroup comparison of blood tests showed that triglyceride, total cholesterol and low-density lipoprotein-C levels were decreased in both groups after 12 weeks of the riding exercise program. However, both groups showed an increase in high-density lipoprotein-C levels, although this difference was not statistically significant. Conclusion : Horseback riding and horseback riding machine exercise showed a positive effect on the serum lipid profile in elderly individuals.

This paper presents a new motor design well suited for an advanced exercise bike. The advanced exercise bike setup high demands for performance and physical dimensions, which is high torque, wide speed range and a diameter/length ratio around 5. These requirements makes the new motor design called an E-core Transverse Flu Machine (ETFM) vev interesting because the segmented design of the stator and rotor poles enables high diameter without increasing the flux-path and since the ETFM is similar to the switched reluctance motor, high torque and wide speed range is possible. The design of the ETFM can be peformed using a developed design program, which is also introduced in the paper. A prototype of the exercise bike with the ETFM and a classical H-bridge converter with analog current control is constructed for verification of the concept.

In this paper, we propose a system that can perform dumbbell exercise by recognizing the weight of dumbbells without wearing and device. With the development of virtual reality technnology, many studies are being conducted to simulate the pysical feedback of the real world in the virtual world. Accurate motion recognition is important to the elderly for rehabilitation exercises. They cannot lift heavy dumbbells. For rehabilitation exercise, correct body movement according to an appropriate weight must be performed. We use a machine learning algorithm for the accuracy of motion data input in real time. As an experiment, we was test three types of bicep, double, shoulder exercise and verified accuracy of exercise. In addition, we made a virtual gym game to actually apply these exercise in virtual reality.

The purpose of this study was to analyze the effects of smart machine circulation exercise on body composition, lung function, blood lipid and insulin resistance in obesity middle-aged women among 40-60 years by dividing them into a smart machine circulation exercise group(n=8), and control group(n=6). The smart machine circulation exercise program included 55-minutes sessions thrice each week at the following intensities: The strength of aerobic exercise is applied to smart machines by linking the smart machine with the POLAR T31; the 1-4 week is 40-50%HRR, 5-8 week is 50-60%HRR, and 9-10 week is 60-70%HRR. The strength of the resistance exercise was tested using a smart machine based on the constant velocity motion, and then, using the 1-RM data value, applied 40% 1-RM for 1-4 weeks, 60% 1-RM for 5-8 weeks, and 80% 1-RM for 9-10 week. As a results, body composition indicated that weight, BMI, %BF, WHR had a significant interaction effect. Lung function indicated that FVC levels significantly changes in the exercise group and the between groups difference in changes at 10week was significant. Also, FVC and FEV₁ significantly showed interaction effect. TC, TG and HDL-C levels significantly changes in smart machine circulation exercise group and the between-group difference in changes after 10 weeks was significant. TC, TG and HDL-C significantly showed interaction effect. Insulin resistance demonstrated that Insulin, Glucose and HOMA-IR levels significantly showed difference over 10 weeks between group. Therefore, the 10 weeks smart machine circulation exercise positively effects on the body composition, lung function, blood lipids, and insulin resistance in obesity middle-aged women and this smart machine circulation exercise can improve their obesity and prevent obesity.

This paper deals with Energy Harvesting using a part of physical energy which is generated by pulldown actions. From a point of energy harvesting view, though it is difficult to regenerate constant energy during pulldown exercise unlike cyclic exercise and running machine exercise, it is possible to regenerate some energies to charge batteries for mobile phones. To investigate possibility of energy harvesting during pulldown exercise, a voltage regulation experiment was performed with a converter circuit and a motor which is attached to the exercise equipment. And we conclude that energy harvesting is possible although its small quantity during pulldown exercises.
