“…In the present included studies, the most common body parts of CWI were submerged to the iliac crest, the legs immersed, to ensure that the lower limbs were fully submerged in the tubs. The water temperature for immersion to the iliac crest ranged from 5 °C to 15 °C (Pointon et al, 2012a;Pointon and Duffield, 2012;Machado et al, 2016;Amir et al, 2017;Chow et al, 2018;Siqueira et al, 2018;Wiewelhove et al, 2018), including the water temperature for immersion to the umbilicus (Ingram et al, 2009;Rupp et al, 2012). In the other studies, it was ensured that participants were submerged in the water bath, with the water immersion to the midsternal level (Halson et al, 2008;Peiffer et al, 2010a;Brophy-Williams et al, 2011;Glasgow et al, 2014;Minett et al, 2014) and shoulders (Parouty et al, 2010;Roberts et al, 2014;Takeda et al, 2014;Fonseca et al, 2016;Argus et al, 2017).…”
