P 16 The implementation of Near-Infrared-Spectroscopy (NIRS) in sports science – a verification of suitability using the compound movement squat

Near - Infrared Spectroscopy (NIRS) serves as a promising tool to examine cortical activity in a sports-scientific context. The associated feasibility of said method remains to be validated as exercise - induced confounders such as increases in extracerebral blood flow have been postulated (Tachtsidis and Scholkmann, 2016). Additionally, the relationship between force and cortical activity is yet to be investigated in compound movements. Both parameters show a linear relationship in isolated movements (Shibuya et al., 2014) yet it remains unclear whether this relationship applies to compound movements.
