Pedagogical control scales of vertical jumping performance in untrained adolescents (13-16 years): research by strata.

Background: A scale is used to establish performance ranges in different sciences, it being necessary to design specialized biological and pedagogical indicators in physical activity, sport and health.

Objective: To design a scale for the pedagogical control of the vertical jumping ability in untrained adolescents (13-16 years), stratifying the sample by age range, ethnicity, urban and rural area, socioeconomic level, and gender.

Methods: A representative sample of the Ecuadorian population ( = 3,705) is studied, classifying it into the aforementioned strata, controlling the vertical jump by ISAK I and II level experts, applying the Sargent Test to measure vertical jumps on a multi-force wall, establishing scales with seven percentile levels, and making comparisons related to chronological age, gender, socioeconomic, and genetic indicators.

Finger Flexor Force Influences Performance in Senior Male Air Pistol Olympic Shooting.

The ability to stabilize the gun is crucial for performance in Olympic pistol shooting and is thought to be related to the shooters muscular strength. The present study examines the relation between performance and finger flexor force as well as shoulder abduction isometric force in senior male air pistol shooting. 46 Spanish national level shooters served as test subjects of the study.
