Which assessments measure strength in the NASM model?

The partial curl-up and modified push-up tests are effective assessments for measuring strength in the NASM model because they specifically evaluate the muscular endurance of the core and upper body, respectively. These tests help trainers determine how well an individual can perform movements that require significant muscular strength and endurance, which are crucial for daily activities and overall fitness.

The partial curl-up test focuses on the abdominal muscles, while the modified push-up assesses upper body strength, particularly in the chest, shoulders, and triceps. Both tests provide valuable insights into an individual’s fitness level and are straightforward to administer, making them practical tools for fitness professionals in their assessments.

The other options listed focus on different areas: the overhead squat test assesses functional movement patterns and flexibility rather than pure strength, the Rockport walk test evaluates cardiovascular fitness, and the dynamic postural assessment is more about assessing posture and stability during movement rather than directly measuring strength. This distinction highlights why the selected answer is specifically relevant for strength assessment in the context of NASM's approach.
