Abstract

PURPOSE: The aim of this study was to develop a method to monitor responses to training loads on an individual basis in recreational long-distance runners (LDR) through training impulses (TRIMP) analysis. The hypothesis tested was that TRIMP on the basis of individually determined weighting factors could result in a better quantification of training responses and performance in LDR in comparison to methods on the basis of average-based group values. METHODS: The training load responses of eight LDR (aged 39.9 ± 6.5 yr) were monitored using a modified version of the average-based TRIMP called individualized TRIMP (TRIMPi) during a period of 8 wk. The TRIMPi was determined in each LDR using individual HR and lactate profiles determined during an incremental treadmill test. Training-induced effects on performance (5-and 10-km races) and changes in submaximal aerobic fitness (speeds at selected blood lactate concentrations of 2 and 4 mmol•L) were assessed before and at the end of the training intervention. RESULTS: Speed at 2 mmol•L (+21.3 ± 5.2%, P <0.001) and 4 mmol•L (+10.6 ± 2.4%, P <0.01) concentrations significantly increased after training. Improvements in running speed (%) at 2 mmol•L (r = 0.87, P = 0.005) and 4 mmol•L (r = 0.74, P = 0.04) concentrations were significantly related to weekly TRIMPi sum. No significant relationship between any variable was detected when average-based group values were used. The TRIMPi was significantly related to 5000-(r =-0.77; P = 0.02) and 10,000-m track performances (r =-0.82; P = 0.01). CONCLUSIONS: Individualized TRIMP is a valid tool in tracking fitness (speed at 2 and 4 mmol•L) and performance (i.e., 5000-and 10,000-m races) in LDR and is more valuable than the methods on the basis of average-based group values. TRIMPi could predict race performance in LDR.
