The purpose of this study was to examine the physiological and biological factors associated with ultra‐endurance performance. Fourteen male runners volunteered to run on a treadmill as many kilometers as possible over a 24‐h period (24TR). Maximal oxygen uptake (V̇O2max), velocity associated with V̇O2max () and running economy (RE) at 8 km/h were measured. A muscle biopsy was also performed in the vastus lateralis muscle. The subjects ran 149.2 ± 15.7 km in 18 h 39 ± 41 min of effective…

Physiological Parameters Associated With 24 Hour Run Performance: 3491 Board #252 May 30, 8
TLDR
A high VO2max may allow runners to maintain faster mean running speeds throughout the race; however numerous other variables such as pacing, nutrition and motivation may limit its ability to be an accurate predictor of 24 h race performance.
Factors affecting metabolic cost of transport during a multi-stage running race
TLDR
Lower CoT values were related to greater muscular power and lower FPI, suggesting that a better ankle stability is likely to achieve better performance in an ultra-endurance running competition.
Performance Factors in a Mountain Ultramarathon.
TLDR
Performance was neither correlated to the level or uphill energy cost of running nor to the changes of these costs post-MUM, suggesting that training should take into account muscle strength of the KE, MAS and FMAS.
Physiological intensity profile, exercise load and performance predictors of a 65-km mountain ultra-marathon
TLDR
The results support the idea that VT1 represents a boundary of tolerable intensity in this kind of events, where exercise load is extremely high, and can be helpful in identifying optimal pacing strategies to complete such extremely demanding MUMs.
Acute metabolic responses to a 24-h ultra-marathon race in male amateur runners
TLDR
The results of this study may imply that progressive decline in partial CO2 pressure (hypocapnia) that develops during prolonged exercise may contribute to increased interleukin-6 production.
Physiological characteristics of an aging Olympic athlete.
TLDR
This longitudinal case indicates that until the age of 40 yr, a steady increase in the oxygen pulse may have compensated for the significant decline in the maximal heart frequency and the maintenance of aerobic and anaerobic exercise capacities allowed this Olympic athlete to compete at the highest level for almost two decades.
Prediction of Performance in a Short Trail Running Race: The Role of Body Composition
TLDR
The classical variable VO2max together with fat mass percent are two strong predictors for short trail running performance.
Pacing and Changes in Body Composition in 48 h Ultra-Endurance Running—A Case Study
TLDR
The findings of the present study offered valuable insight in the pacing and changes of body mass and body water during a 48 h run, and this information can be used by ultra-endurance runners and practitioners working with them.
Changes in Running Economy During a 65-km Ultramarathon
TLDR
This is the first study to demonstrate a consistent increase in O2 cost and Cr among a range of different slopes, at individual running speeds and race-specific slopes giving further evidence that these measures of RE increase in UM running.
Central and peripheral contributions to neuromuscular fatigue induced by a 24-h treadmill run.
TLDR
The results suggest that central factors are mainly responsible for the large maximal muscle torque reduction after ultraendurance running, especially on the KE muscles.

Physiological measures associated with marathon running performance in high-level male and female homogeneous groups.
TLDR
It is demonstrated that in males and females, physiological parameters can explain the variance in marathon time among elite homogeneous groups.

ENERGY EXPENDITURE AND INFLUENCE OF PHYSIOLOGIC FACTORS DURING MARATHON RUNNING
TLDR
The results indicate the influence of body size on marathon run performance in recreational runners, as the larger male and female runners ran slower and expended more kilocalories than smaller runners.
Onset of blood lactate accumulation and marathon running performance.
TLDR
Marathon running performance was closely related to VOBLA and to the ability to run at a pace close to that velocity during the race, which were in turn related to % ST, capillary density, and training volume.
Aerobic performance of female marathon and male ultramarathon athletes
TLDR
The data suggests that success at the marathon and ultramarathon distances is crucially and (possibly) solely dependent on the development and utilisation of a large VO2 max.
Estimated aerobic performance and energy cost of severe exercise of 24 h duration.
TLDR
By the nature of the activity this figure must be regarded as at or near the upper limit of sustainable energy expenditure by man during a complete uninterrupted 24 h circadian cycle.
Physical and training characteristics of top-class marathon runners.
TLDR
The high energy output seems to be the discriminating factor for top-class male marathon runners who trained at higher relative intensities.
Applied Physiology of Marathon Running
TLDR
Present indications are that marathon runners, compared with normal individuals, have a higher turnover rate in fat metabolism at given high exercise intensities expressed both in absolute (m/sec) and relative %V̇O2 max terms.
Peak treadmill running velocity during the VO2 max test predicts running performance.
TLDR
In groups of trained long distance runners, the physiological factors that determine success in races of 10-90 km are the same; thus there may not be variables that predict success uniquely in either 10 km, marathon or ultra-marathon runners, and peak treadmill running velocity is at least as good a predictor of running performance as is the lactate turnpoint.
Endurance exercise performance: the physiology of champions
TLDR
The performance of elite athletes is likely to defy the types of easy explanations sought by scientific reductionism and remain an important puzzle for those interested in physiological integration well into the future.
