Sexual maturation effect on physical fitness in girls: a longitudinal study

Biological Maturation and Hormonal Markers, Relationship to Neuromotor Performance in Female Children

“…Similar to the objective of the present study, Lowe et al, [37] addressed that hormonal markers in the group of estrogens including estradiol interact with strength levels in women throughout life, and Aslam et al, [8] recently reported that there is a relationship between hormone levels during puberty and neuromotor skills in subjects of both sexes. In the same context to the objective of the present study, seeking to find relationships between maturation and neuromotor performance, Volver et al, [27], in a longitudinal study, analyzed 34 female subjects aged between 11 and 13 years old and, the authors concluded that sexual maturation influences neuromotor skills suggesting a possible interaction of factors related to puberty, such as hormone levels for example.…”

“…In view of this approach, it is worth mentioning that hormonal levels influence the acquisition of lean mass and that lean mass is closely linked to the production of strength during the execution of neuromotor skills [4,23,27,44,45], and in this context young people with biological maturity accelerated body weight, greater concentration of lean mass, and a higher concentration of hormone levels [1,22,23,46]. This fact can also be confirmed in the results of the present study, corroborating the findings of Goswami et al [26], where the authors showed that the muscular power of the lower and upper limbs is associated with maturation and that this association is significantly influenced by sex hormones, and that discriminating that with advancing maturation stages, the concentrations of hormone levels tends to increase.…”

“…In this sense, it is likely that one of the mechanisms related to strength gain during the maturational process is hormone-mediated [25][26][27]. Thus, in view of the foregoing, our hypothesis is that the maturational stages and levels of hormone markers in the body may be significantly related to the performance of neuromotor skills.…”

Skeletal age and explosive strength in young volleyball players

“…hey include the largest responses of anabolic hormones, such as testosterone 20 and structural changes in muscle architecture, resulting signiicant changes in type I to type II ibers proportion 21,22 , observed in younger age. Volver et al 23 , further complement that the anabolic androgenic actions in the pubertal period stimulate the development of type II muscular ibers, responsible for explosive force generation. However, because of their invasive nature, metabolic responses in children and adolescents according to maturational development are limited.…”

Relationship between bone age, hormonal markers and physical capacity in adolescents

“…According to Goswami et al 1 muscle strength is a component of physical fitness affected by altering secretion of sex hormones which may contribute to the better performance by subjects of a more advanced maturational state, which had, in parallel, an increased concentration of the labelled hormone. In this sense, Volver et al 22 also attribute anabolic androgen actions in the pubertal stimulation of the development of fast-twitch muscle fibres, which are responsible for generating explosive power. These data can be taken as parameters for a better adult life in regard to daily demands, since muscle strength is considered an important indicator of physical fitness and health.…”
