Normative-referenced percentile values for physical fitness among Canadians.

Background: This study developed age- and sex-specific normative-referenced percentile values for five physical fitness tests across a wide age range of Canadians, using a nationally representative sample.

Data And Methods: The data are from 5,188 Canadians (50.1% female) and were collected as part of cycle 5 of the Canadian Health Measures Survey (2016 to 2017).

Results: Males had slightly better cardiorespiratory fitness and substantially better grip strength, jumping height and jumping power scores than females, whereas females had better sit-and-reach flexibility. Among females, there were pronounced increases in jumping height (P50: 25%) and jumping power (P50: 58%) between ages 8 and 13, and in grip strength (P50: 193%) between ages 6 and 19. Performance gradually declined with age, beginning in adolescence for jumping ability and at approximately age 35 for grip strength. Among males, there were pronounced increases in jumping height (P50: 69%) and jumping power (P50: 233%) between ages 8 and 20, and in grip strength (P50: 365%) between ages 6 and 20. Performance gradually declined with age, beginning immediately after adolescence for jumping ability and at approximately age 30 for grip strength. Sit-and-reach flexibility remained relatively stable with age in both sexes. Cardiorespiratory fitness scores in both sexes declined steadily with age beginning (generally) at age 8, with a larger decline evident in females until age 18.

Discussion: These normative-referenced values for physical fitness could be useful for screening in public health and clinical practice.
