Resistance Training Improves Physical Performance and Reduces Noncontact Injuries in Young Soccer Players

Strategic Insights -

A recent study published in the International Journal of Sports Physiology and Performance has found that young trained soccer players who participate in a resistance-training program with a frequency of two sessions per week show significant improvements in physical performance and reduced noncontact injury severity compared to those who participate in one session per week. The study, conducted by researchers from the University of Cadiz, aimed to compare the effects of two different frequencies of an integral-periodization resistance-training program on physical performance and incidence of noncontact injury in young trained soccer players during an entire season.

Key Takeaways:

  • The study involved 40 young trained soccer players, aged 16.6 years, who were randomly divided into two groups: frequency 1 (F1G, n = 18) and frequency 2 (F2G, n = 22).
  • Physical performance was assessed using countermovement jump, progressive loading tests for squat and hip-thrust, 10-m and 30-m sprint tests, the V-Cut test, and the 30-15 Intermittent Fitness Test.
  • The frequency 2 group showed significant improvements in all tests, with effect sizes ranging from 0.40 to 4.35 (all P < 0.05).
  • Noncontact injuries were also recorded and classified by severity, with the frequency 2 group showing reduced noncontact-injury severity.
  • The study found that performing two resistance training sessions per week within an integral-periodization model led to superior physical performance improvements and reduced noncontact-injury severity in young trained soccer players compared to one session per week.

Statistics:

  • 40 young trained soccer players participated in the study.
  • The frequency 2 group showed significant improvements in countermovement jump (ES = 2.35, P < 0.05).
  • The frequency 2 group showed significant improvements in 10-m sprint test (ES = 2.15, P < 0.05).
  • The frequency 2 group showed significant improvements in V-Cut test (ES = 4.35, P < 0.05).
