## 5 Discussion and Conclusions  
The present study investigated the continuous intention of older adult participants in virtual reality sports by applying sports commitment to extend TPB. Using this method, the present study predicted the motivation for and ongoing pursuit of personal goals among older adult participants in sports, producing three major empirical results. First, the results of the study showed that sports commitment can predict continuance intention. The results demonstrated that high sports commitment and low sports commitment have the same significant effect as TPB variables. [PERSON] [46] found that TPB variables have a significant effect on motivation and intention toward regular physical activity in a large number of studies, even when the attendance rate is low. However, [PERSON] [46] did not address continued sports commitment and TPB. For older adult participants, continued participation is important. Sports commitment includes continued motivational factors, which can be directly used to measure an individual's psychological condition [38], and provide future motivational factors for individuals. For example, competitive supports may be more likely to reflect individual intrinsic motivation, such as feelings of enjoyment or challenge. However, fitness activities may be more likely to reflect extrinsic motivation, such as benefits in terms of appearance, weight, and stress management [56]. The motivations of older

Second, the present study found that attitude, subjective norms, and perceived behavioral control all influence behavioral norms, verifying [PERSON]'s [50] TPB. Of these, subjective norms are the strongest predictors of continuous intention for older adult participants in virtual reality sports, showing that the intention to continue participation in sports is influenced by one's peers. According to TPB, subjective norms can predict normative beliefs, reflecting whether an individual's behavior is influenced by certain influential groups. The most crucial outcome is whether there is participation behavior. Because people are social animals, when making decisions, aside from their own feelings, they are also influenced by the people around them. The main reason is that people hope that their own decisions are affirmed by others, or that they do not want their decisions to be at odds with others', thereby influencing their relationships. Older adult participants in virtual reality sports also require the support of family and friends to motivate their continued participation. Third, perceived behavioral control has a stronger effect on continuous intention for participants in virtual reality sports than sports commitment or attitude. In addition, the perceived behavioral control comes from direct experiences or actual contact with knowledge and information. This special attitude structure can change existing beliefs [42]. Older adults tend to become rigid in their thinking, and retired people are not able to obtain information about technology as quickly as younger people can. Therefore, it is necessary to provide friendly advice services. This is because when individuals have more access to resources and opportunities, they will face fewer expected obstacles. Greater evaluations of perceived behavioral control are associated with greater continuance intention. Aside from its theoretical contributions, the present study can assist, in practical terms, relevant organizations, such as older adults' welfare institutions and nursing homes, when planning leisure activities for the older adults, or firms when developing software marketing strategies.
