Self-Perceived and Self-Tested Endurance: Associations with Objective Measures.

Area of Science:

• Exercise Physiology
• Sports Science
• Health Measurement

Background:

• Self-report questionnaires are cost-effective for large-scale physical fitness screening.
• Previous research shows inconsistent validity for self-perceived fitness assessments.
• A hybrid method involves self-administered objective measurements.

Purpose of the Study:

• To compare the relative validity of self-perceived fitness versus self-administered objective measurements.
• To assess the accuracy of these self-report methods against objective treadmill testing.

Main Methods:

• 26,452 Norwegian conscripts (men and women) participated.
• Two groups: one self-rated endurance, the other self-tested a 3000m run.
• All participants later completed an objective maximal treadmill test.

Main Results:

• Both self-perceived and self-tested endurance correlated similarly with objective treadmill performance (men: r_s=0.59; women: r_s=0.50).
• Analyses of variance confirmed that higher self-reported endurance predicted faster treadmill times.
• Moderate group-level agreement was observed, but significant individual measurement error exists.

Conclusions:

• Self-perceived and self-tested endurance methods demonstrate comparable validity for group-level fitness assessment.
• While useful for large samples, individual fitness reporting via these methods requires caution due to measurement error.
