6.4. Research Limitations and Future Research Directions
We recruited the participants who were all college students. These participants were suitable because of their homogeneity and were unlikely to introduce features that would bias the research results. To increase the generality of our research findings, future studies could replicate the research work by recruiting participants other than students.The influence of playing exergames on users’ physical and psychological health were explored, but emotional impact was not included. Emotions may affect the continual intention of the participants. Therefore, future works might explore whether playing exergames could effectively trigger emotional changes, so boosting continual intention of playing exergames.A randomized controlled trial was used, one of the most rigorous experimental designs to investigate whether and for whom playing exergames enhances quality of life. However, the mechanism underlying the positive impacts of playing exergames on quality of life was not explored. Therefore, future works might apply qualitative research designs to further uncover the detailed process underlying the findings herein.
