Limitations and strengths
This study presents both strengths and limitations. Prior to this study, there was scarce information about BL interventions related to future cardiac physiotherapy professionals. In addition, there is a scarcity of randomized trials using BL among physiotherapy students. Moreover, this study highlights the inclusion of several online resources based in scientific evidence in the BL intervention that are not usually included or detailed in other studies. Nevertheless, our results must be taken with caution because of the short period evaluated, thus we recommend that future research investigate the long-term effects of BL. Moreover, since the research sample consisted of physiotherapy students from a single university in Spain, it is difficult to generalize the results to other university degrees and may have low external validity. It should be taken into account that several non-validated instruments were used. In addition, some of the analyzed outcomes are the self-perceptions of the study participants, therefore further studies that use objective measurements are highly recommended in this regard. Exploring the effects on the psychomotor skills of students would be an interesting aspect to evaluate when performing this type of study. It would be interesting for future research to mimic this work in other university degrees to obtain more representative results. Future studies should consider these limitations and investigate how digital learning designs could facilitate the students' learning, practical skills, and behaviors, as well as determine the useful benchmarks as part of improving the teaching-learning process in digital educational environment combined with face-to-face methodologies.
