The experimental design depicts the two days of data collection, separated by a day of rest with measures before (PRE-WALKNODOMS) and after walking (POST-WALKNODOMS) without delayed onset muscle soreness (DOMS) on day 1 and before (PRE-WALKDOMS) and after walking (POST-WALKDOMS) with presence of DOMS on day 2. IRT: Infrared thermography; NPRS: Numeric pain rate scale (for DOMS evaluation); Borg: report of rate of perceived exertion using Borg’s scale.
