Force-Velocity Characteristics, Muscle Strength, and Flexibility in Female Recreational Marathon Runners
Physical fitness components that relate with performance in marathon running, e.g., aerobic capacity and body composition, have been studie…
High-intensity intermittent “5–10–15” running reduces body fat, and increases lean body mass, bone mineral density, and performance in untrained subjects
The present study examined the effect of intense intermittent running with 5 s sprints on body composition, fitness level, and performance …
The effects of beetroot juice supplementation on exercise economy, rating of perceived exertion and running mechanics in elite distance runners: A double-blinded, randomized study
Purpose Nitrate-rich beetroot juice supplementation has been extensively used to increase exercise economy in different populations. Howeve…
Pacing Strategies in the ‘Athens Classic Marathon’: Physiological and Psychological Aspects
Despite the increased scientific interest in the relationship between pacing and performance in marathon running, little information is ava…
The Relationship between Running Power and Running Economy in Well-Trained Distance Runners
A novel running wearable called the Stryd Summit footpod fastens to a runner's shoe and estimates running power. The footpod separates powe…
Girls in the boat: Sex differences in rowing performance and participation
Men outperform women in many athletic endeavors due to physiological and anatomical differences (e.g. larger and faster muscle); however, t…

Low testosterone in male endurance-trained distance runners: impact of years in training
The study examines the impact of years of training on testosterone levels in male endurance runners.
Hip and spine bone mineral density are greater in master sprinters, but not endurance runners compared with non-athletic controls
Summary We examined bone density in older athletes and controls. Sprinters had greater hip and spine bone density than endurance athletes a…
Effects of Plyometric Training on Explosive and Endurance Performance at Sea Level and at High Altitude
Plyometric training performed at sea level enhance explosive and endurance performance at sea level. However, its effects on explosive and …
Self-Reported Periodization of Nutrition in Elite Female and Male Runners and Race Walkers
Athletes should achieve event-specific physiological requirements through careful periodization of training, underpinned by individualized …
Influence of Endurance Training During Childhood on Total Hemoglobin Mass
Elite endurance athletes are characterized by markedly increased hemoglobin mass (Hbmass). It has been hypothesized that this adaptation ma…
Physiology and Pathophysiology in Ultra-Marathon Running
In this overview, we summarize the findings of the literature with regards to physiology and pathophysiology of ultra-marathon running. The…
Effects of Vitamin D Supplementation on Haematological Values and Muscle Recovery in Elite Male Traditional Rowers
ion: De cient levels of 25-hydroxyvitamin D (25(OH)D) ( 0.05). Regression multivariate analysis showed that cortisol and testosterone level…
