The Running Energy Reserve Index: Mapping, Assessment and Prediction

Project Number
RI 6/11 GB

Project Duration
January 2012 - March 2016


Measurement of anaerobic peak energy or anaerobic performance is an important parameter in sports activities. There are many methods available to measure anaerobic performance such as oxygen debt, blood lactate and maximal accumulated oxygen deficit (MAOD) etc but there is a need for a valid, reliable, accurate, easy and convenient method. MAOD may be an accurate method to measure anaerobic performance but there are limitations (Saltin, 1990; Vandewalle et al., 1987a). MAOD is also not an easy and convenient method to measure anaerobic performance. besides physiological methods, there are mathematical models available to measure anaerobic energy such as models based on Hill's speed and duration relationship (Bundle et al., 2003). Various sports activities involve a combination of anaerobic and aerobic energy. Therefore, subtracting the peak aerobic energy from the peak anaerobic energy used un running may give an accurate information on anaerobic performance (De Prampero et al., 1993, Ward Smith, 1999). On the basis of this principle, one method was developed to measure anaerobic performance among runners using the concept of Anaerobic Speed Reserve (AnSR, Bundle et al., 2003). AnSR utilizes peak aerobic energy and peak anaerobic energy to predict anaerobic performance accurately (Bundle et al., 2003). However, this method can only predict the running performance from 3 to 240s. Similar to Bundle et al's (2003) study, a running energy reserve index (RERI) will be developed in this study. An index will be developed using maximal aerobic and maximal anaerobic speed based on oxygen consumption. This index will be termed as RERI. Therefore, the primary aim of the present study is to develop RERI to measure anaerobic performance.
