Background: Previously, we developed a mathematical model capable of predicting pubertal development (PD) through seven anthropometric variables, with an accuracy of 75%. We believe that it is possible to develop a similar model that uses fewer anthropometric measurements and provides greater precision.
Objective: Develop a mathematical model capable of predicting PD through anthropometric variables.
Purpose: Although spurts in physical capacities during adolescence are well known, little is known about the existence of such spurts in sport-specific skill development, especially during the period of rapid growth in stature. Our aims were to examine the timing, intensity, and sequence of basketball-specific skill spurts aligned with biological (years from peak height velocity (PHV)) rather than chronological age. We then defined putative sensitive periods (windows of optimal development) for each skill aligned to the adolescent growth spurt.

Article Synopsis
- Success in speed swimming relies on the efficiency of the anaerobic energy system, particularly during muscle power production in athletes.
- A study involving 60 adolescent swimmers revealed that relative upper limb power (ULP) was significantly greater than relative lower limb power (LLP) and both were correlated with swimming performance in a 50-meter race.
- Lean mass in the limbs and biological maturation were positively linked to increased ULP and LLP, indicating their importance in swimming speed.
Increasing children's physical activity engagement has short- and long-term health benefits. Developing physical competence is a key component of children's engagement in physical activity. The purpose of our study was to assess if a 12-week home, school, and community-based physical literacy intervention improved the physical competence of children in kindergarten and grade one.
