Physiological changes arising from a training programme in under-21 international netball players

Area of Science:

• Sports Science
• Exercise Physiology
• Human Performance

Background:

• Understanding physiological differences across playing units in young athletes is crucial for targeted training.
• Quantifying the impact of structured training programs on key performance indicators is essential for athlete development.

Purpose of the Study:

• To analyze physiological status variations among different playing units in an under-21 international squad.
• To measure physiological and anthropometric changes in these athletes following a four-month training intervention.

Main Methods:

• Collected physiological and anthropometric data from 21 under-21 international athletes.
• Assessed maximal/peak oxygen uptake (VO2 max) via treadmill running and anaerobic performance using the 30s Wingate test.
• Compared pre- and post-training data, analyzing differences between playing units.

Main Results:

• Significant differences in height, body mass, and forced vital capacity (FVC) were observed between playing units before training.
• The training program led to significant improvements in height, body mass, FVC, and anaerobic performance.
• While VO2 max showed a trend towards increase, it was not statistically significant; however, anaerobic performance became significantly dominant post-training.

Conclusions:

• Playing units exhibit distinct anthropometric characteristics, necessitating position-specific training considerations.
• A four-month training program effectively enhances body composition and anaerobic capacity in young elite athletes.
• The training intervention shifted the performance profile towards a greater anaerobic contribution, highlighting its importance for this cohort.
