Introduction
Quantifying training is an important step in the training process. Doing so means that training can be objectively analyzed, appropriate training loads identified, and suitable adjustments made in an attempt to improve performance and reduce the incidence of injury and illness (2).
Using Session-RPE Training Load (S-RPE TL) as a method of quantifying training has been investigated for a number of different training modalities and sports including speed skating, basketball, cycling, rugby league, soccer, and resistance training (3, 4, 6, 8, 10). Training loads and variation of loads, as quantified by the S-RPE TL method, has been related to incidence of illness (3) and injury (6). Additionally, comparisons have been made with heart rate (HR) based training loads, along with measures of volume and intensity in the weight room (8, 10).
Heart rate (HR) monitoring as a measure of training loads typically uses time spent in specific zones (based on % of HR max or HRR), multiplied by a coefficient points system. The Edwards method is an example of this (5).
The Polar Team2 Training Load (Team2 TL) is a new HR based form of quantifying training. When considering the use of a new measurement tool or system, it is important to investigate its validity. A comparison with a previously studied method, such as the S-RPE TL, is a step towards this.
