Differences in Physical Performance and Body Composition Between National and Non-National Youth Female Handball...

Area of Science:

• Sports Science
• Human Movement Science
• Talent Identification in Sports

Background:

• Performance disparities in female youth handball are often attributed to differences in strength, speed, and power.
• Elite athlete selection requires understanding the key physical differentiators in young players.

Purpose of the Study:

• To compare the physical conditioning capacities and body composition of national team female youth handball players versus non-national team peers.
• To identify the specific physical attributes that distinguish selected national team players.

Main Methods:

• A comparative study involving 36 female youth handball players (18 national, 18 non-national).
• Assessment of anthropometry, sprint and change of direction ability, vertical jump, strength, aerobic capacity, and body composition.
• Statistical analysis using independent-samples t-tests, Mann-Whitney U tests, and Cohen's d for effect size.

Main Results:

• National team players demonstrated significantly higher jump height and relative peak power.
• Selected players exhibited significantly faster 20 m sprint times.
• No significant differences in body composition were observed; a moderate effect size indicated potential aerobic capacity advantages for national team players.

Conclusions:

• Explosive power and linear speed are critical performance indicators for selecting female youth handball players for national teams.
• While other physical capacities may be trainable, power and speed appear to be key discriminators at this level.
