INTRODUCTION: Health-related physical fitness (HRPF) demonstratesan inverse association with several cardiovascular risk factors in young people; however, few studies have investigated the alterationsin HRPF indicators throughout a determined period. OBJECTIVE: To analyze the secular trend of HRPF indicators in children of seven to 10 years of age. METHODS: In total, 1,136 subjects were analyzed, seven to 10 years of age, in three-time periods (2002, 2005, 2010-2011). The HRPF tests were: sit-and-reach (SR), abdominal resistance (AB), 9 min walk/run test (9min), and body adiposity by the skinfold sum (∑SF). Classification of the HRPF indicators was carried out by the Physical Best cut-off point. The ANCOVA test (controlled by BMI, height and ∑SF) was used to compare the differencesin HRPF indicators betweenthe three-time periods. RESULTS: Boys presented a 6% decrease in flexibility between the 2010 and 2002 periods; no significance was found in the AB test; children of both sexes presented higher values in the 9min test in the 2005 period. CONCLUSION: It was concluded that there was a negative secular trend for HRPF, in that the individuals studied in 2010 presented inferior results to their peers (2002-2005) for HRPF, in both sexes, except for abdominal strength and endurance.
