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.

Summary: The study characterized trail running injuries among Portuguese male and female recreational athletes, finding a high incidence of injuries with specific locations and types reported. There was a negative correlation between total exposure time and injuries per 1000 hours, with significantly increased injury rates for those who did not warm up.

Summary: This study investigates the relationship between pacing strategy and performance during uphill and downhill running. The results suggest that energy distribution is associated with participants' race finish times, and overly aggressive uphill pacing may lead to worse performance.

Summary: Participants in trail running races are required to carry their equipment throughout the race, which alters their running biomechanics. This study used a new running powermeter to analyze the effects of running with additional weights on running power generation and running kinematics at submaximal speed. The results showed that running with a weighted vest had acute effects on various running metrics, with higher ground contact time and mean power output, and lower duty factor, vertical oscillation, and flight time observed when running with 10% body mass compared to lighter loads. The study suggests that running with lighter loads can enhance running power generation and leg spring stiffness.

Summary: This study examined the effects of heat training in a heat chamber or while wearing a heat suit on hemoglobin mass and endurance performance in elite cyclists. Both heat training methods were found to increase hemoglobin mass and improve performance. Additionally, maintaining heat training by wearing a heat suit led to a sustained increase in hemoglobin mass during a subsequent maintenance period.

Summary: The effects of plyometric training (PT) on pacing behavior were evaluated in this study. The results showed that PT improved drop jump performance and running economy, but did not directly affect pacing behavior, ratings of perceived exertion, or affective feelings during a 10-km time trial run.

Summary: The study revealed that running uphill on a trail significantly increases oxygen cost of running and the magnitude/variability of feet medio-lateral accelerations compared to running on a treadmill, regardless of the a priori technicity level. Despite lower perceived technicity on the treadmill, there was no difference in perceived exertion between trail and treadmill runs.

Summary: The study found that critical speed (CS) had a better predictive power for the 5-km running performance of recreational runners compared to peak running velocity determined on the track field (V-peak_TF). CS1,(2),(3) and CS1,(3) were identified as having the highest predictive power for the 5-km running performance of recreational runners.

Summary: The study found that in the 50-km race, training volumes, cardiovascular health, aerobic fitness, and a greater loss of body mass during the race were related to better performance. In the 80-km and 160-km races, only peak velocity achieved in the maximal oxygen uptake test predicted performance. The results suggest that physiological determinants of success may differ in their impact as race distance increases.

Summary: The study analyzed the pace strategy of finalists in swimming and running world events held in 2021-2022. The results showed statistically significant differences between swimming and running in terms of total time, average time of splits, median time of splits, and maximal length of split sequences. However, there was no significant difference in the number of sequences of splits and the percentage of splits faster than the median speed.

Summary: Success in long-distance running is influenced by factors such as oxygen utilization, lactate metabolism, and genetic associations. The Gly allele of the PPARGC1A Gly482Ser rs8192678 polymorphism has been linked to endurance athlete status and favorable adaptations to aerobic training. This study examined the association of rs8192678 with elite status and performance among long-distance runners. The results showed that athletes carrying the Ser allele had a 2.5% faster performance compared to Gly/Gly homozygotes.

Summary: The aim of this study was to uncover the cognitive rules developed by athletes in pacing strategy during a trail running competition. Fifty participants completed a questionnaire regarding the decision-making process behind pacing. The results showed that pleasure and effort significantly influenced the decisions to reduce or maintain the pace, with different cognitive rules applied for each outcome.

Summary: In this work, a three-tier hierarchical structure is designed to overcome the trade-off between HTC and CHF. By defining nucleation sites with microcavities and incorporating nanostructures, the bubble coalescence is minimized and evaporation is promoted, leading to significant enhancement in both HTC and CHF compared to a smooth surface.

Summary: The study compared the effects of programmed fluid intake and thirst-driven fluid intake on prolonged cycling performance and exercise associated muscle cramps. The results showed that programmed fluid intake can increase power output during a 20 km time-trial, but there was no significant difference in the prevalence of muscle cramps of the plantar flexors between the two drinking conditions.

Summary: The study investigated volunteer athletes in the Leadville Trail 100 Run in August 2014, collecting blood samples before and after the race, and found that some participants experienced acute kidney injury after the race. The study also attempted to back-calculate creatinine levels for runners without known baseline creatinine levels using medical equations, concluding that there is no accurate way to estimate baseline Cr in this population.
