“…Furthermore, Lee and Kim [8] reported that sports VR training significantly influenced coordination related to balance and postural stability. In addition to this, various studies have found that VR simulation-based exercise increases body stability [27][28][29]. In other words, we can predict the mechanism by which VR increases action duration, as seen in this study: a sense of balance can enhance the stable continuation of a certain posture.…”

Background This study explored the use of virtual reality (VR) technology to enhance the effectiveness and duration of low-intensity movements and postures in Pilates-derived exercises. We postulate that by leveraging the flow state in VR, individuals can engage in these exercises for longer periods while maintaining a high level of flow. Objective The purpose of this study was to compare differences in posture maintenance and flow between VR Pilates training and conventional Pilates training, and the correlation between the 2 factors. Methods The 18 participants in each group received either VR training or conventional training and were switched to the other training type after a 2-day wash-out period. Each group performed Pilates movements in a VR environment and a conventional environment, divided into 4 types. After training sessions, participants were evaluated for flow using a self-report questionnaire. In addition, a sports video analysis program was used to measure the duration of posture maintenance in 2 video-recorded sessions. Repeated-measures ANOVA and correlation analysis were performed on the measured duration of posture maintenance and flow scores. In all cases, the statistical significance level was set at P<.05. Results Results for the duration of posture maintenance verification by type showed that simple behavior (F1,16=17.631; P<.001), upper body–arm coordination behavior (F1,16=6.083; P=.04), upper body–leg coordination behavior (F1,16=8.359; P<.001), and whole-body coordination behavior (F1,16=8.426; P<.001) all showed an interaction effect at P<.05. Flow (F1,16=15.250; P<.001) also showed an interaction effect. In addition, significant correlations were determined between duration of all types of posture maintenance and flow in the VR training group at P<.05. Conclusions Our results indicate that VR Pilates training may be more useful than conventional Pilates training in improving the duration of posture maintenance and that it promotes a significantly higher degree of flow when compared with conventional Pilates training.

“…Therefore, appropriate sports VR training (game-based) is seen as an important factor in the trunk alignment, and it also affects the strength, balance, and quality of life of the lower extremities. Recently, studies with various age groups and materials included VR gears [14,[16][17][18] have been continuing and have been taking place as an effective training method. In this study, sports VR training which may be helpful for aerobic exercise and may strengthen cardiopulmonary showed better effect on coordination (body composition).…”

The purpose of this study is to find out the effect of sports virtual training with applied sports science and information and communication technology (ICT) for adults. We have developed a 4-week workout program that focuses on improving basic endurance, strength, and function. The experiment is to derive the kinematic data for ergonomic evaluation of indoor sports device combined with a virtual image and to compare and evaluate the pre-and post-body composition. Twenty-one participants were selected, and each training program was conducted considering individual differences and levels. Results showed that 4-week sports virtual reality (VR) training program developed in this study turned out to be appropriate as a sport VR training one to improve body composition and health. Although it is difficult to generalize the effect to all human, it is meaningful to study some ways of reducing the heterogeneity and improving the training efficiency in the situation where the sports VR system is gradually being applied to the exercise.

Technology improvements and cost reduction allow electrochemical energy storage systems based on Lithium-ion cells to massively be used in medium-power applications, where the low system cost is the major constraint. Battery pack maintenance services are expected to be required more often in the future. For this reason, a low-cost instrumentation able to characterize the cells of a battery pack is needed. Several works use low-cost programmable units as Li-ion cell tester, but they are generally based on proprietary-software running on a personal computer. This work introduces an open-source software architecture based on Python language to control common low-cost commercial laboratory instruments. The Python software application is executed on a Raspberry Pi board, which represents the control block of the hardware architecture, instead of a personal computer. The good results obtained during the validation process demonstrate that the proposed cell station tester features measurement accuracy and precision suitable for the characterization of Li-ion cells. Finally, as a simple example of application, the state of health of twenty 40 Ah LiFePO4 cells belonging to a battery pack used in an E-scooter was successfully determined.
