27-year-old track and field athlete, simplified exercise testing without lactate measurements


Subject

  • 27 years old, male, healthy
  • 143.9 lbs, 5.84 ft
  • Since 3 years competitions in track and field, 400m running)
  • PB 51.1 sec for 400m
  • On average, 4 training sessions per week, 1 to 2 times basic endurance training
  • No former exercise testing

Issues

  • Control and guidance of training intensities for basic endurance training
  • Fitness check and evaluation of cardiopulmonary fitness by means of running

Exercise testing

  • Multistage test in the field with heart rate monitoring but without lactate measurements
  • Step duration 3 minutes
  • Start with 6 km/h, increment by 2 km/h per step

Excerpt

  • Maximal work rate: 18 km/h for 3.0 minutes
  • Work rate at the IAT ("Individual anaerobic threshold"): 13.68 km/h (3,80 m/s)
  • Heart rate at the IAT: 201 bpm
  • Endurance capacity is at the 89th percentile beyond all strength-, speed- and teamsport athletes of the same age group
  • Relative VO2max (estimated): 57.0 ml/min/kg body weight

Interpretation

  • Basic endurance capacity is outstanding relative to the type of sports (400m running)
  • Intensity recommendations are given with the print report
  • Recommend follow-up tests for all about 6 to 12 months

How's that possible: Lactate diagnostics without lactate (and also without gas exchange measurements)?

Without measurement of lactate, your exercise test results (work rate, heart rate) can be interpreted sufficiently by Ergonizer. This is possible by the "under the hood" usage of multifactorial prediction models that are founded on ten-thousands of former reference examinations.

The results without lactate and without breath gases of course will be little less reliable and valid - but with a gain in applicability. You have the option:
