Table 2. Effect of firefighting personal protective equipment on the heart rate and rating of perceived exertion during treadmill walking training.

Variables	Group	Before exercise	Right after exercise	Changes of before and after exercise
Heart rate (beats/min)	RC test	75.8 ± 3.2	133.3 ± 3.6^###	57.4 ± 4.1
Heart rate (beats/min)	PPE test	86.4 ± 3.2	176.6 ± 2.7^###	90.2 ± 4.6^***
Rating of perceived exertion	RC test	2.5 ± 0.5	6.0 ± 0.5^###	3.5 ± 0.6
Rating of perceived exertion	PPE test	3.6 ± 0.3	9.1 ± 0.3^###	5.5 ± 0.4^*

Values are means ± SE. RC: regular clothing; PPE: personal protective equipment. ^###Mean statistical differences for p<0.001 (paired t-test) between before exercise and right after exercise. ^{*, ***}Mean statistical differences for p<0.05, p<0.001 (Student t-test) between RC and PPE.
