The performance indicators of elite athletes aged 15-16 in sports-related activities

Abstract

Abstract  

Objective of the study was to pinpoint the characteristics of the athletic performance of adolescents aged 15-16 in sports radio direction finding during the process of energy provision for muscular activity in the context of aerobic-anaerobic transition.

Methods and structure of the study. The research was conducted in Kislovodsk in November 2023, during the training camps. The participants were 12 members of the Russian youth national team in the age group of 15-16 years, including one Master of Sports, eight Candidates for Master of Sports, and three athletes with first-category status.

During the experiment, a treadmill test was performed. The participants performed muscle work with gradually increasing load until they reached exhaustion. Breathing was monitored to measure the concentration of oxygen and carbon dioxide in nanometers, while heart rate and lactate levels in the blood were also determined.

Based on the collected data, the aerobic and anaerobic thresholds were calculated, expressed in terms of running speed, oxygen consumption per minute, and heart rate.

Results and conclusions. It was discovered that the lactate levels in the blood of skilled athletes aged 15-16 who participate in sports radio direction finding are within the expected range and are equal to 2,4 mmol∙l^‒1 at the aerobic threshold and 4,3 mmol∙l^‒1 at the anaerobic threshold. The average speed at the anaerobic threshold is 3,01 m*s^‒1, at the anaerobic threshold – 4,02 m*s^‒1, and at the maximum power consumption – 4,71 m*s^‒1.

The most informative indicators in sports radio direction finding for skilled athletes aged 15-16 are the oxygen consumption at the anaerobic threshold, the speed at the anaerobic and maximum power consumption thresholds.
