Purpose: To determine the effect of drafting on running time, physiological response, and rating of perceived exertion (RPE) during 3000-m track running.
Methods: Ten elite middle- and long-distance runners performed 3 track-running sessions. The 1st session determined maximal oxygen uptake and maximal aerobic speed using a lightweight ambulatory respiratory gas-exchange system (K4B2). The 2nd and the 3rd tests consisted of nondrafting 3000-m running (3000-mND) and 3000-m running with drafting for the 1st 2000 m (3000-mD) performed on the track in a randomized counterbalanced order.
Results: Performance during the 3000-mND (553.59±22.15 s) was significantly slower (P<.05) than during the 3000-mD (544.74±18.72 s). Cardiorespiratory responses were not significantly different between the trials. However, blood lactate concentration was significantly higher (P<.05) after the 3000-mND (16.4±2.3 mmol/L) than after the 3000-mD (13.2±5.6 mmol/L). Athletes perceived the 3000-mND as more strenuous than the 3000-mD (P<.05) (RPE=16.1±0.8 vs 13.1±1.3). Results demonstrate that drafting has a significant effect on performance in highly trained runners.
Conclusion: This effect could not be explained by a reduced energy expenditure or cardiorespiratory effort as a result of drafting. This raises the possibility that drafting may aid running performance by both physiological and nonphysiological (ie, psychological) effects.

Purpose: This study aimed to analyze the competitive demands of mountain running races of varying lengths.
Methods: Sixty-six male athletes competed in Vertical race (∼3 km and ∼1000 m of total elevation change), Sky race (∼25 km and ∼3000 m of total elevation change), and SkyUltra race (∼80 km and ∼9000 m of total elevation change). Exercise intensity and competition load (TL) were assessed using running power, heart rate, and rating of perceived exertion (RPE).

This study evaluated the effects of advanced footwear technology (AFT) spikes on running performance measures, spatiotemporal variables, and perceptive parameters on different surfaces (track and grass). Twenty-seven male trained runners were recruited for this study. In Experiment 1, participants performed 12 × 200 m at a self-perceived 3000 m running pace with a recovery of 5 min.

Background: Resting heart rate (HR) and HR variability (HRV) are widely used parameters to assess cardiac autonomic nervous system function noninvasively. While resting assessments can be performed during sleep or after awakening, it would be relevant to know how interchangeable the results of these measurements are. This study aimed at examining the alignment between nocturnal and morning assessments during regular endurance training and in response to intensive training.

Purpose: To examine the reproducibility and sensitivity of a self-paced field running test (SFT) in monitoring positive and negative changes in endurance performance.
Methods: A total of 27 (11 women) recreational runners participated in a 6-week training intervention. The intervention was divided into a 3-week baseline period, a 2-week overload period, and a 1-week recovery period.
