Effects of integrating intermittent training, interval training, and small-sided games on aerobic capacity in youth soccer players using a 3:1 periodized micro-cycle

Key Points

• To assess the effects of integrating intermittent training, interval training, and small-sided games on aerobic capacity in youth soccer players.
• Involved U16 and U19 teams using a 3:1 periodized micro-cycle design.
• Utilized integrated training models combining various training styles.
• Evaluated performance improvements in aerobic capacity for players in central and specific positions.
• U16 players showed significant improvement with an effect size of r = 0.78.
• U19 players demonstrated greater improvements with an effect size of r = 0.94.
• Central-position players' improvements were minimal (U16: r = 0.21; U19: r = 0.17).
