Test understanding of how aerobic, anaerobic (strength), and flexibility exercises influence heart rate, muscle function, recovery, and overall fitness for Grade 6–8 students. Assess ability to describe physiological responses (for example, how aerobic activity raises and sustains heart rate, how anaerobic strength work builds muscle power, and how flexibility training improves range of motion), compare benefits and limitations, and recommend age-appropriate examples and balanced routines. Include short analysis and application items that ask students to explain why each exercise type produces specific changes and how they work together to improve health.
