Effects of Personal Protective Equipment on Metabolism and Performance During an Occupational Physical Ability Test for Federal Highway Police Officers

The objective of this study was to evaluate the effects of load carriage on physiological, perceptual, and performance responses during an Occupational Physical Ability Test (OPAT). Thirteen male FHP officers completed an OPAT with PPE (WPPE, load = 12.0 kg) and without PPE (NPPE, load = 5.2 kg) in 2 separate sessions in a randomized and counterbalanced order. Metabolic responses (heart rate [HR] and its variability, and blood lactate concentration [Lac]), perceptual (rating of perceived exertion [RPE]), and OPAT performance were measured. Paired t and Wilcoxon tests were used to identify differences between conditions, and 2-way analysis of variance with Bonferroni post hoc was performed to analyze the results of Lac between the conditions. Occupational Physical Ability Test completion time was significantly greater in the WPPE condition compared with the NPPE condition (125.9 ± 13.8 vs. 118.3 ± 11 seconds, p
