Study limitations
The main limitation of the present study was the sample size, the G2 group (parathletes) did not have the same training and control as the G1. The socioeconomic level of G1 was low, making it difficult to travel to the hospital, the availability of time to carry out the training program and the clinical implications made it difficult to include a greater number of patients. Therefore, the comparison with the present study is diversified, making a more robust synthesis difficult. The possibility of type II error due to the variability of data within a relatively small sample must be acknowledged, particularly with regard to outcomes. Another important issue is that the lack of long-term follow-up prevents a better analysis of the benefits of the methods used.
