Abstract
The study aimed to determine: (1) the validity between self-reported and objectively measured physical fitness and (2) the percentage of agreement. Two - hundred and seventy - five healthy men and women attending police academy (32% women) were
randomly recruited. Self-report was obtained from a 10 - point scale, where higher score indicates better physical fitness perception. Measured physical fitness tests were:
(1) body – mass index, (2) polygon backwards, (3) standing broad jump, (4) sit – and – reach test and (5) 2.4 km run. Spearman’s and Kappa statistics were used to determine
the validity and the level of agreement between the two measures.
Higher level of self-reported physical fitness was correlated with all tests and physical fitness index in men (r = -0.61 to 0.79) and women (r = -0.59 to 0.78), except for
body – mass index in both sexes. The level of agreement was weak in both men (κ = 0.42, p < 0.001) and women (κ = 0.38, p < 0.001). Self-reported measure provides moderate to high level of validity and weak agreement when measuring physical
fitness in first year police officers.
