We thank the authors of the letter [1] for their interest in our proposed conceptual framework for physical training [2]. The contribution of Bertollo et al.[1] from a sport psychology perspective is greatly appreciated and we believe the authors succeeded in their attempt to integrate a different but complementary perspective on an interdisciplinary approach as advocated by the Grand Unified Theory proposed by Paul Glazier (2017)[3].
