Resumo
Background and Aim: In everyday practice, the anthropometric assessment including
measures of skinfolds and body girths must be performed avoiding previous physical
exercise. However, few studies are conducted using situations with ecological validity.
Thereby, this study aimed to compare if 10k treadmill run alters skinfold measures and
body girths of runners. Methods: Eighteen runners of both sexes and levels (34 ± 6 years
old with 8 ± 7 years of run practice and 63.6 ± 8.8 ml*kg-1*min-1 of VO2
max) underwent
body girths, skinfolds thickness and body weight assessments before and after the 10k run.
The anthropometric parameters were compared by Student’s t-Test dependent for paired
samples and correlations between body weight reduction and anthropometric parameters
were compared by Pearson’s correlation coefficient with α= 5%. Results: The 10k run
reduces 1.4% of body weight. However, no significant changes were observed in the sum
of skinfold thickness or body girths. The percentage of body weight reduction also was
not correlated with the exercise-induced changes in skinfold thickness and body girths.
Conclusion: Although 10k run causes a body weight reduction, the skinfold thickness and
body girths not altered in previously trained individuals and was not correlated with body
weight reductions. In this way, the use of these anthropometric assessment techniques can
occur both before and after a conventional training session in runners.
