Competitive orienteers maintain high heart rates during events, with intensity varying by course type. Age did not significantly impact heart rate during exercise, indicating similar aerobic and anaerobic demands across different orienteering courses.

Area of Science:

  • Sports Science
  • Exercise Physiology
  • Human Movement Studies

Background:

  • Orienteering is a demanding sport combining navigation and running.
  • Understanding the physiological responses during competition is crucial for training and performance optimization.

Purpose of the Study:

  • To investigate the heart rate profiles of experienced orienteers during competitive events.
  • To analyze the influence of different course types (fast run, slow run, highly physical) on physiological responses.
  • To examine the relationship between age and heart rate during orienteering.

Main Methods:

  • 16 experienced competitive orienteers (aged 15-62 years) participated.
  • Heart rate was monitored during three distinct course types: fast run (FR), slow run (SR), and highly physical (HP).

  • Statistical analysis (ANOVA) was used to determine the significance of course type on mean heart rate.

    • Main Results:

    • Orienteers consistently exhibited heart rates between 140-180 beats min-1 during most of the event.
    • Course type significantly affected mean heart rate (P < 0.001), with FR (160 bpm) and HP (158 bpm) eliciting higher rates than SR (150 bpm).
    • No significant correlation was found between age and mean heart rate, with older (>45 years) and younger orienteers showing similar profiles.

    Conclusions:

    • Orienteering involves predominantly aerobic activity with intermittent anaerobic bursts, irrespective of age.
    • Technical skill and slower running pace on certain courses lead to lower mean heart rates, despite similar overall physical demands.
    • Age is not a limiting factor for maintaining high exercise heart rates in experienced orienteers.
