Abstract
PURPOSE: This study compared the effects of a standardized endurance training program with individualized endurance training modified based on the cumulative training load provided by the Polar Training Load Feature.
METHODS: After 12 weeks of similar training, 24 recreationally endurance-trained men were matched to a training load-guided (TL, n=10) or standardized (ST, n=14) group and continued training for 12 weeks. In TL, training sessions were individually chosen daily based on an estimated cumulative training load, while in ST the training was standardized with 4-6 sessions·week(-1). Endurance performance (Shortest 1000m running time during an incremental field test of 6×1000m) and heart rate variability (HRV) were measured every 4 and VO2max during an incremental treadmill test every 12 weeks.
RESULTS: During weeks 1-12, similar changes in VO2max and 1000m time were observed both in TL (+7±4%, p=0.004 and -6±4%, p=0.069) and ST (+5±7%, p=0.019 and -8±5%, p<0.001). During weeks 13-24, VO2max statistically increased in ST only (3±4%, p=0.034). 1000m time decreased in TL during weeks 13-24 (-9±5%, p=0.011) but in ST only during weeks 13-20 (-3±2%, p=0.003). The overall changes in VO2max and 1000m time during weeks 0-24 were similar in both TL (+7±4%, p=0.001 and -9±5%, p=0.011) and ST (+10±7%, p<0.001 and -13±5%, p<0.001). No between-group differences in total training volume and frequency were observed. HRV remained statistically unaltered in both groups.
CONCLUSIONS: The main finding was that training performed according to the cumulative training load led to similar improvements in endurance performance as standardized endurance training in recreational endurance runners.
