Exercise Intensity Thresholds: Identifying the Boundaries of Sustainable Performance
CRITICAL POWER MAXIMAL LACTATE STEADY STATE RESPIRATORY COMPENSATION POINT NIRS BREAKPOINT EXERCISE TOLERANCE
2017/4/20
Critical power (CP), respiratory compensation point (RCP), maximal lactate steady state (MLSS), and deoxyhemoglobin breakpoint ([HHb]BP) are alternative functional indices that are thought to demarcat...
Motor Performance as Predictor of Physical Activity in Children: The CHAMPS Study-DK
FITNESS AGILITY ACTIVITY LONGITUDINAL ASSOCIATION YOUTH
2017/4/20
Purpose: Physical activity (PA) is associated with several health benefits in children, and PA habits developed in childhood tend to persist into adulthood. PA may be the foundation of a healthy lifes...
Recent Advances in Iron Metabolism: Relevance for Health, Exercise, and Performance
IRON HEMOGLOBIN MUSCLE HEPCIDIN MYOGLOBIN
2017/4/19
ABSTRACT: Iron is necessary for physiological processes essential for athletic performance, such as oxygen transport, energy production, and cell division. However, an excess of “free” iron is toxic b...
The Effect of Ischemic Preconditioning on Repeated Sprint Cycling Performance
ISCHEMIA OCCLUSION POWER OUTPUT MULTIPLE SPRINT FATIGUE
2017/4/19
Purpose: Ischemic preconditioning enhances exercise performance. We tested the hypothesis that ischemic preconditioning would improve intermittent exercise in the form of a repeated sprint test during...
