, Intensity
Lecture 1 – intensity & load (1/3)
Ultimate goals:
Sports: produce a winning performance at the right time and place.
Rehab: to enhance and restore functional ability and quality of life of those with physical impairments
of disabilities
You need to improve → understand the mechanism!
Overload: apply more stress on the body than the athlete is normally got to improve → body will adapt
most of the time; dependent on many factors → FIT triad:
Frequency: how often do the load
Intensity: how high intensity → difficult to monitor.
Time: how long
Side effects → injury etc.
Fine line between optimal load and overtraining → You need a good intensity to improve, but not to
high → looking for the limits.
Tapering
Optimal training → reduce intensity → decrease in performance.
Tapering: reduce training load (number of sessions/ time, but not intensity!)
What is exercise intensity?
Is it really difficult to define intensity. It is a combination of the parameters which are related to the
performance output, energy expenditure and the subjective feeling of the athlete.
- Performance output → really what you do:
• Absolute force/power/velocity → coordinated action (GPS), isolated muscle group.
This does not always reflect intensity → many influencing factors (terrain,
environmental conditions, etc.)
• %MVC, %Pmax → related to the maximal performance of the athletes
• Critical power (Pcrit): highest power output than can be maintained for a very long
time.
- Energy expenditure
• Absolute energy expenditure
• %VO2max, %VO2max or MET
• %HRmax or %HRR (Heart rate reserve) → internal
• Thresholds: anaerobic/lactate/ventilatory → more or less the same
▪ Lactate threshold: exercise intensity at which the body produce more lactate
then it consumes → accumulation of lactate → problem is the acid: pH
decrease, muscles do not function properly anymore.
We know the intensity, how high should it be to improve the aerobic fitness?
50% VO2max/HRR is the minimum, but it is not easy, do we really know?
