Short-Term Speed Variability as an Index of Pacing Stochasticity in Athletic Running Events

Competition Between Desired Competitive Result, Tolerable Homeostatic Disturbance, and Psychophysiological Interpretation Determines Pacing Strategy

Carl Foster et al.

Summary: Scientific interest in pacing, as a feature of athletic competition and a window into understanding fatigue, has spanned more than 100 years. Pacing represents the pattern of energy use designed to produce a competitive result while managing fatigue of different origins. Various models, such as the teleoanticipation model and the central governor model, have been used to explain pacing. Early studies focused on managing homeostatic disturbance, while more recent studies have focused on understanding the role of psychophysiology in pacing and explaining performance decline.

Pacing profiles and tactical behaviors of elite runners

Arturo Casado et al.

Summary: The pacing behaviors of elite athletes vary depending on the sport and race distance. Factors such as fast start, positive pacing patterns, and U-shaped pacing strategies are observed in different events. Athletes should carefully choose their pacing strategies to optimize performance and consider differences between meet races and championship races.

Weekly vagal modulations and their associations with physical fitness and physical activity

Andra R. Medeiros et al.

Summary: RMSSD, a marker of global health and training adaptations, has been proposed as a tool for assessing weekly vagal modulations. Daily LnRMSSD recordings showed varying day-to-day reliability and agreement across different conditions, with stronger correlations observed during walking activities. Utilization of weekly HRV recordings may provide practitioners with a practical alternative for investigating cardiac autonomic function.

Interaction of exercise bioenergetics with pacing behavior predicts track distance running performance

Brett S. Kirby et al.

Summary: The best possible finishing time of a runner in distance track events depends on their critical speed (CS) and the finite energy that can be expended above CS. The interaction between pacing strategies, initial CS, and D' balance predicts final race finishing positions. The D' balance model accurately predicts finishing positions in both slow and fast races, highlighting the impact of pacing strategy on race outcomes.

Pacing Profiles of Middle-Distance Running World Records in Men and Women

Arturo Casado et al.

Summary: The study compared the pacing patterns of all-time 800m, 1500m, and mile running world records, finding no significant differences in pacing strategies between sexes. It was observed that women were more likely to break world records during championships than men.
