摘要：The purpose of this study was to assess students’ perceived exertion in a Physical Education (PE) setting. In addition, it was analyzed the class actual duration, the average time for physical practice, and its relationship with the health guidelines on physical activity. 1,853 males and females between 10 and 18 years old (M= 13.7 ± 1.8) participated in this study . The measure of perceived exertion was performed using the Pictorial Children's Effort Rating Table (PCERT). All classes were recorded (videotape) and observed by experts who reported scores on the content and the duration of the PE sessions . The results indicated: (1) a PE class duration of 38.7 (± 4.9) minutes, (2) an average time for physical practice (M= 22.3 ± 4.8) minutes and (3) students ’ perceived exertion scores (M= 4.57 ± 2.0) on a 10-point scale . Significant gender differences were observed on perceived exertion (p <0.01), especially on Fitness ' content (p <0.001). The duration of PE class is not respectful of the curriculum guidelines with respect to the time that would be allocated to this subject at school . Actual-time physical activity does not reach at least the thirty minutes of physical exercise necessary to expect health benefits . The class represents an effort with vigorous intensity only for one out of three students .
