We read with interest the article by Boereboom et al. in the Scandinavian Journal of Medicine Science in Sport1 . This well-performed study showed that a short (8 sessions over 19 days) pre-operative exercise training program increased exercise time and work-load in the second cardiopulmonary exercise test (CPET), but did not lead to a change in participants’ peak VO2. We agree with the statement in the discussion that “Further work should be undertaken to explore exercise modality, training intensity, interval length and session frequency to try and determine an optimal HIIT protocol to improve the cardiorespiratory fitness (CRF) of preoperative patients in the short time-frame available”.
