Biomarkers predicting the effectiveness of normobaric altitude training Open
Purpose The aim of the present study was to identify blood-based biomarkers that could predict individual VO 2 max improvement before the start of an artificial altitude training camp. Methods In an exploratory intervention study, 15 young…

Drafting, pacing, priming—potential factors for winning the 1500 m men final at the 2024 Olympics Open
Background Considering the season bests before the Olympics as well as individual critical speed, the question arose as to why the obviously fastest runner of the 2024 season, Jakob Ingebrigtsen, did not become Olympic champion over 1500 m…

Training in normobaric hypoxia induces hematological changes that affect iron metabolism and immunity Open
Altitude training is a method among endurance athletes to enhance performance via hypoxia-induced adaptations. However, individual responses vary significantly, with some athletes even showing performance decrements. Iron metabolism and im…

Faster intervals, faster recoveries - intensified short VO2max running intervals are inferior to traditional long intervals in terms of time spent above 90% VO2max Open
Introduction High intensity interval training for improving maximal oxygen consumption (VO 2max ) is a fundamental component of specific preparation phases for middle- and long-distance runners. In this context, short intervals are very po…

Relationship between Longitudinal Upper Body Rotation and Energy Cost of Running in Junior Elite Long-Distance Runners Open
Running is a basic form of human locomotion and one of the most popular sports worldwide. While the leg biomechanics of running have been studied extensively, few studies have focused on upper-body movement. However, an effective arm swing…

From Incremental Test to Continuous Running at Fixed Lactate Thresholds: Individual Responses on %VO2max, %HRmax, Lactate Accumulation, and RPE Open
With Norway’s successes in middle and long-distance running, lactate-guided threshold training has regained importance in recent years. Therefore, the aim of the present study was to investigate the individual responses on common monitorin…

Effect of Uphill Running on VO2, Heart Rate and Lactate Accumulation on Lower Body Positive Pressure Treadmills Open
Lower body positive pressure treadmills (LBPPTs) as a strategy to reduce musculoskeletal load are becoming more common as part of sports conditioning, although the requisite physiological parameters are unclear. To elucidate their role, te…

Energy Cost of Running Under Hypogravity in Well-Trained Runners and Triathletes: A Biomechanical Perspective Open
Hypogravity treadmills have become a popular training tool in distance running and triathlon. Counter-intuitively, tibial acceleration load is not attenuated by hypogravity unloading during running, while, equally surprisingly, leaps becom…
