This study aimed to assess the mobility and thermal comfort of personal protective equipment (PPE) amongfemale healthcare workers, taking into account wearers' physique and PPE protection levels. A total of 16 participants(age: 26.3 ± 8.3 y, height: 161.5 ± 7.3 cm, body weight: 57.1 ± 11.0 kg, BMI: 21.9 ± 3.6), representing diverse bodytypes, underwent four PPE conditions: L (Low_Plastic gown ensemble), M (Medium_Tyvek 400), H (High_Tyvek 800Jwith Powered Air Purifying Respirator [PAPR]), and E (Extremely high_Tychem 2000 with PAPR, Bib apron, and Chem-ical-resistant gloves). The mobility protocol consisted of 10 different tasks in addition to donning and doffing. The 10 taskswere repeated twice at an air temperature of 24.3 ± 0.1°C, 59±4%RH. Findings revealed a disproportionate relationshipbetween PPE protection and wearer discomfort. Significant differences in clothing microclimate and total sweat rate wereobserved between the lowest (L) and highest (E) protection levels (p < 0.01), while distinctions among medium levelswere inconclusive. Subjective evaluations favored conditions H and L over M and E (p < 0.05), indicating reduced heat,and humidity, increased comfort, and lower exertion. Instances of mobility discomfort, specially in the small body typegroup, underscored the need for a suitable PPE size system for Korean adult female medical workers. Furthermore,enhancements in gloves, shoe cover, and PAPR hood designs are essential for improving ease of movement and pre-venting hindrance.
