Resumen
POLITANO, Hugo et al. Comparative study of aerobio power between maturational stages determined by menarche. Rev. salud pública [online]. 2020, vol.22, n.1, pp.48-53. Epub 19-Ene-2021. ISSN 0124-0064. https://doi.org/10.15446/rsap.v22n1.84380.
Objective
To identify and compare the aerobic power between the maturation stages determined by menarche.
Methods
Participated 19 students from 10 to 14 years of the primary school of a private school in the city of Itajubá-MG, practicing physical school activities; six from stage M0, seven from stage M and six from stage M1. The study used a quasi-experimental typology and a comparative design. Statistically, Anova One-Way was used to compare variables between maturation stages, followed by Tukey's post-hoc. The level of significance was p<0.05.
Results
Descriptively, the aerobic power was identified in the three stages of maturation, being absolutely: M0 1.7 ± 0.32, for M 2.2 ± 0.26 and for M1 2.6 ± 0.43 L/min and relatively: M0 41.4 ± 1.72, for M 46.5 ± 4.51 and for M1 43.9 ± 5.42 ml/kg.min. There was a significant difference with p = 0.001 in the absolute maximum VO2, with a progressive increase in the absolute maximum VO2 along with sexual maturation, without significant difference in the relative maximum VO2 with p = 0.125.
Discussion
the conclusion We conclude that there is a significant increase in the absolute maximum VO2 together with the progression of maturation, and in the relative maximum VO2, we did not identify significant differences between the maturation stages determined by menarche with a decrease after one year of occurrence of menarche.
