Unfortunately, many older adults lack sufficient PA, due to reasons such as PA not being enjoyable for them. As a result, older adults are unable to maintain their motivation for the initiation and continuation of PA. In our previous works, a boxing glove-type sensory augmentation system was developed to solve this problem by inducing enjoyment during PA. However, the effect of our device on physical and cognitive capabilities, which are crucial for well-being, and motivation for initiation and continuation of PA remains unclarified. In this study, we aimed to evaluate these effects. We hypothesized that our device may help improve capabilities, and that the enjoyment it provides may potentially contribute to increased motivation for initiation and continuation of PA. Fourteen healthy older adults participated in the study. Kickboxing lessons for the older adults using our device were conducted a total of five times over a six-week period, and the participants were free to attend the sessions as many times as they wished. They participated in three measurement sessions: pre-measurement before the lesson period, post-lesson measurement after each lesson, and post-measurement at the end of the lesson period to evaluate the effects of our device. Physical capabilities were assessed through two-step, stand-up, and center-of-pressure tests. Cognitive capabilities were assessed using illustration memory and computation tests. Mental state was assessed using a positive and negative affect schedule (PANAS). Subjective evaluations of enjoyment and motivation for the initiation and continuation of PA through the use of our device were also conducted. In the results, physical and cognitive capabilities and mental states tended to improve. Subjective evaluations indicated increased enjoyment from using our device and greater perceived effectiveness in motivating PA initiation and continuation. These evaluations improved over time. While the pre-post design without a control group limits causal interpretation, improvements in physical, cognitive, and mental states may have contributed to enhanced enjoyment.

This paper uses the methods of match observation, mathematical statistics, literature and other methods to carry out an empirical comparative study on the representative segmented diagnostic indicator system constructed by predecessors in the past 20 years. Research suggests that: 1) in the New Ball Era, each segmented diagnostic indicator system has a certain degree of rationality, but in comparison, the five-segment diagnostic indicator system is the most optimal and the most accurate to reveal the technical and tactical performance in the new era. 2) The five segments consist of the serving-attacking segment, receiving-attacking segment, serving-attacking connection segment, receiving-attacking connection segment, and the sustaining segment. 3) The impact of these five segments on the outcome of the match is as follows: The \"attacking\" segments have the greatest impact on the match outcome, followed by the \"connecting\" segments, and the \"sustaining\" segment has the smallest impact. The impact of the receiving and attacking segment on the outcome of the match is higher than that of the serving and attacking segment, and the impact of the serving and attacking connection segment on the outcome of the match is higher than that of the receiving and attacking connection segment. 4) In the New Ball Era, the fifth and sixth strokes of the \"connecting\" segment have gained prominence, playing a pivotal role for transitioning between offense and defense in the \"attacking\" segment and the \"sustaining\" segment. These findings highlight the need for coaches and analysts to adopt the five-segment diagnostic indicator system as a more accurate framework for evaluating performance. Emphasizing training in the receiving-attacking and connecting phases-especially the fifth and sixth strokes, can provide a competitive edge under the dynamics of the New Ball Era.
