Summary: This study aimed to quantify the test-retest reliability of strength measures in adolescent distance runners and explore the relationships between inter-limb strength asymmetry and performance and running economy. The results showed that relationships between strength asymmetry and performance and RE were generally low, except for a higher correlation between hip abduction strength asymmetry and RE in female participants.

Summary: The study indicates that acute BJ supplementation improves 2 km running performance in amateur runners primarily by enhancing performance in the second half of the race. Additionally, the benefits in performance enhancement and reduction in overall perceived exertion are similar in males and females.

Summary: Males consistently outperform females in athletic endeavors, although the sex gap is not fixed and varies with different factors. The difference in performance between males and females is lowest for world record holders and increases for lower-ranked elite athletes. Various factors, including physiological, sociocultural, psychological, and sport-specific factors, contribute to the sex difference. Measures should be taken to reduce the sex gap and enable both sexes to reach their full potential.

Summary: The differences in power meters and gestures between cycling and running affect the determination of Critical Power (CP) intensity. Cycling has extensively studied CP, but with the introduction of power measurement in running, it can now be examined as well. This study aimed to determine if power output at CP intensity is interchangeable between cycling and running segments. The results showed significant differences between CP in cycling and running, with running CP being overestimated compared to cycling CP. Therefore, a specific test for each discipline is necessary for an accurate determination of CP.

Summary: The purpose of this study was to investigate the effects of a 2-km swim on the cycling power-duration relationship. The results showed that total work done decreased after swimming, while end-test power and work done above end-test power did not significantly differ. Therefore, triathletes should determine racing cycling power following a simulated race-pace swim.

Summary: This study compared the effects of running and cycling on energy cost when matched for duration and relative intensity. The results showed that cycling significantly increased energy cost at mid and end of exercise, while running did not show any changes in energy cost throughout the duration. Changes in energy cost during cycling were correlated with muscle fatigue and changes in cadence.

Summary: Transcranial direct current stimulation (tDCS) has been shown to have positive effects on athletic performance, particularly in endurance exercises such as running and cycling. However, the effects of anodal-tDCS may vary depending on the specific task, with an enhancement in endurance performance seen in time to exhaustion tasks but not in endurance time trial or sprint tasks. The increase in cortical excitability induced by anodal-tDCS could potentially reduce perceived exertion during physical tasks. The task being performed should be taken into consideration when evaluating the results of tDCS interventions.

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 parameters measured at lactate minimum in running and cycling were significantly lower, but highly correlated with values at maximal lactate steady state, which allows to estimate exercise intensity at maximal lactate steady state with one single exercise test.

Summary: This study compared the effects of running and cycling on neuromuscular function. The results showed that despite similar reductions in knee extensor strength after both types of exercise, the mechanisms responsible for force loss differed. Running exercise was associated with greater impairments in nervous system function, particularly at the spinal level, while cycling exercise resulted in greater impairments in contractile function. This may be due to differences in the mechanical and metabolic demands imposed on the quadriceps during these two forms of exercise.

Summary: This study aimed to investigate the pacing during cycling and running splits in three different multi-stage ultra-triathlon race formats. The results showed a significant effect of race distance on total performance, with longer distances resulting in faster performances. Additionally, the pacing during cycling had an influence on the subsequent running performance, with longer races showing a greater impact.

Summary: The aim of this study was to investigate the effect of age and years of running experience on the running economy of amateur long-distance runners aged 20-80 years. The study found that running experience had a positive effect on running economy, but it was not sufficient to overcome the negative effect of the aging process. Furthermore, participants aged >= 60 years had significantly worse running economy compared to younger athletes.

Summary: This study investigated the effects of oregano supplementation on muscle damage, oxidative stress, and plasma antioxidant markers of soldiers performing military training. The results showed that oregano supplementation can reduce muscle damage and increase oxidative capacity. Therefore, supplementation with oregano may serve as a dietary strategy to increase preparedness and promote recovery in military recruits.

Summary: This paper explains the methods used in the InTrack Project, which investigates the variance in the performance of runners from different countries. It aims to understand whether the differences in performance can be explained by individual, environmental, and country-level factors. The study will collect data from runners through an online survey and secondary data about country characteristics. Statistical procedures such as multilevel analysis and interaction models will be used to analyze the data and fill gaps in knowledge about the factors influencing runners' performance.

Summary: Performance in endurance sports decreases with aging due to cardiovascular and musculoskeletal aging, but the factors most affected by aging are still unclear. This study compared two groups of runners (< 50 and > 50 years of age) based on their oxygen uptake, ventilatory threshold, and respiratory compensation point. The younger group had higher oxygen uptake and lean mass-adjusted oxygen uptake compared to the older group, indicating a significant difference. Both central and peripheral factors are negatively affected by aging, but the effect is greater on central factors. These findings contribute to our understanding of how aging affects master runners.
