Biomechanical adaptations during exhaustive runs at 90 to 120% of peak aerobic speed.

The aim of this study was to examine how running biomechanics (spatiotemporal and kinetic variables) adapt with exhaustion during treadmill runs at 90, 100, 110, and 120% of the peak aerobic speed (PS) of a maximal incremental aerobic test. Thirteen male runners performed a maximal incremental aerobic test on an instrumented treadmill to determine their PS. Biomechanical variables were evaluated at the start, mid, and end of each run until volitional exhaustion.

Effect of cold ambient temperature on heat flux, skin temperature, and thermal sensation at different body parts in elite biathletes.

Introduction: When exercising in the cold, optimizing thermoregulation is essential to maintain performance. However, no study has investigated thermal parameters with wearable-based measurements in a field setting among elite Nordic skiers. Therefore, this study aimed to assess the thermal response and sensation measured at different body parts during exercise in a cold environment in biathletes.

Oxygen Uptake at Critical Speed and Power in Running: Perspectives and Practical Applications.

Purpose: Intensity domains are recommended when prescribing exercise, and critical power/speed (CP/CS) was designated the "gold standard" when determining maximal metabolic steady state. CS is the running analog of CP for cycle ergometry. However, a CP for running could be useful for controlling intensity when training in any type of condition.

On the Use of the Repeated-Sprint Training in Hypoxia in Tennis.

Purpose: To examine physiological and technical responses to repeated-sprint training in normobaric hypoxia at ∼3,000 m (RSH, = 11) or in normoxia (RSN, = 11) compared to a control group (CON, = 8) in well-trained tennis players. Participants were 28.8 ± 5.
