An Integrative Neuromuscular Training Program in Physical Education Classes Improves Strength and Speed Performance

Area of Science:

• Sports Science
• Pediatric Exercise Science
• Neuromuscular Physiology

Background:

• Youth physical activity levels and conditioning are critical for long-term health.
• Integrative Neuromuscular Training (INT) combines physical literacy and resistance exercises.
• Optimizing the timing and integration of INT within school curricula is essential.

Purpose of the Study:

• To evaluate the impact of a 4-week INT intervention on strength and speed in Spanish students.
• To compare the effectiveness of INT across different age groups (11-12 and 15-16 years).
• To assess the feasibility of integrating INT into physical education classes (PEC).

Main Methods:

• Longitudinal randomized controlled study with 121 students aged 11-16.
• Four groups: two experimental (INT intervention) and two control groups, stratified by age.
• Experimental groups underwent two 20-minute INT sessions weekly for four weeks, integrated into PEC.

Main Results:

• Significant improvements (p < 0.001) in lower-body power, upper-body power, abdominal endurance, and sprinting speed in experimental groups.
• Both age groups (11-12 and 15-16 years) showed significant gains.
• Younger students (11-12 years) exhibited greater improvements in upper-body power compared to older students (15-16 years).

Conclusions:

• A brief, 4-week INT program effectively enhances strength and sprint performance in youth.
• Integrating INT at the beginning of physical education classes is a viable strategy.
• INT contributes to meeting the physical activity, well-being, and conditioning needs of young people.
