Area of Science:

  • Sports Science
  • Exercise Physiology
  • Soccer Performance Analysis

Background:

  • Understanding maximal heart rate (HRmax) is crucial for training intensity in soccer.
  • Traditional methods of estimating HRmax, such as age-predicted formulas and field tests, may not accurately reflect competition demands.

Purpose of the Study:

  • To compare maximal heart rate (HR) during soccer matches with HRmax estimated from age and field tests.
  • To analyze differences in HR measurements within and between different age categories of soccer players.

Main Methods:

  • HR was monitored in 19 U17, 12 U20, and 14 professional soccer players during official matches and a 1000m run test.
  • Maximal heart rate during competition (MHR1), age-predicted HRmax (MHR2), and HR from effort tests (MHR3) were recorded.

  • Statistical analysis included Wilcoxon and Kruskal Wallis tests with a significance level of P<0.05.

    • Main Results:

    • The highest HR recorded during effort tests (MHR3) was consistently lower than the highest HR during competition matches (MHR1) across all categories.
    • No significant differences in MHR1 were found between the U17, U20, and professional categories.
    • U17 and U20 players showed higher MHR3 values compared to professional players, but were not significantly different from each other.

    Conclusions:

    • Field tests may underestimate maximal heart rate (HRmax) compared to actual competition.
    • Lower HRmax in field tests could be due to reduced athlete motivation in artificial testing scenarios versus competitive matches.
