Association Between Physical Activity Level and Training Volume in Adolescent Athletes

Area of Science:

• Sports Science
• Adolescent Health
• Physical Activity Research

Background:

• Organized sports are widely believed to enhance adolescent physical activity.
• However, evidence indicates structured training may not translate to increased general activity outside formal sessions.

Purpose of the Study:

• To investigate the relationship between physical activity levels and weekly training hours in adolescent athletes.
• To analyze these patterns across different sports, competition levels, age groups, and sexes.

Main Methods:

• A large-scale study involving 10,196 participants aged 11-19.
• Utilized the Spanish version of the Physical Activity Questionnaire and collected data on training volume, competition level, and socioeconomic status.

Main Results:

• Competitive athletes reported higher physical activity, but levels decreased with age despite increased training.
• Girls consistently showed lower physical activity than boys, even with comparable training hours.
• No clear association was found between physical activity level and weekly training hours across various competition levels.

Conclusions:

• Structured sports training does not necessarily lead to higher overall physical activity in adolescents.
• Significant discrepancies exist between training volume and daily activity levels, particularly concerning sex and age.
• Findings challenge the assumption that sports participation inherently boosts adolescent physical activity beyond formal training.
