Conclusion
This study shows that summer RIF observed for the first time by
non-athletic boys aged 12 years had a minimal effect on oxy-sat
but significantly impaired HR during the 6MWT.
The authors express their sincere gratitude to all participants and their
parents for their effort and cooperation. The Ministry of Higher Education
and Scientific Research, Tunisia financially supported the study. MA Fennini
and I Latiri contributed equally to this work. K Chamari and H Ben Saad
contributed equally in this work.
