Background:
Physical education (PE) provides a natural opportunity for students to be physically active during the school day; however, the amount and intensity of this activity varies. The Centers for Disease Control and Prevention recommends that students engage in MVPA for at least 50% of their PE class period. The purpose of the present study was to quantify the amount of MVPA that occurs during elementary school PE.
Methods:
Accelerometer data were collected from 203 students (100 2nd grade; 103 5th grade) in 10 West Virginia elementary schools. At each school, PE teachers identified three 2nd grade classes and three 5th grade classes in which to collect the physical activity data. For each selected class, the teachers identified the first 4 students on their alphabetic roll to wear the accelerometers. PE teachers recorded the date and time of the class and the gender of the students wearing the accelerometers.
Results:
Using 5-second epochs and Puyau's cut-offs, results indicated that, on average, students engaged in MVPA for 27% of their PE class. No significant differences were observed in MVPA between 2nd and 5th grade students or between males and females. Male and female students spent equal amounts of PE class in MVPA.
Conclusion:
Findings support policy to increase the required minimum amount of MVPA during each PE class.

Data Collection III
The principles to begin the physical assessment include conducting a comprehensive or problem-related history in a quiet, well-lit room, emphasizing privacy and comfort for the patient.

Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
Assessment of Respiration
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like asthma or COPD,...
