Endurance Exercise Enhances the Effect of Strength Training on Muscle Fiber Size and Protein Expression of Akt and mTOR
Reports concerning the effect of endurance exercise on the anabolic response to strength training have been contradictory. This study re-in…
Exercise duration-matched interval and continuous sprint cycling induce similar increases in AMPK phosphorylation, PGC-1α and VEGF mRNA expression in trained individuals
Purpose The effects of low-volume interval and continuous ‘all-out’ cycling, matched for total exercise duration, on mitochondrial and angi…
Nitrate Intake Promotes Shift in Muscle Fiber Type Composition during Sprint Interval Training in Hypoxia
Purpose: We investigated the effect of sprint interval training (SIT) in normoxia, vs. SIT in hypoxia alone or in conjunction with oral nit…
Influence of High vs. Low Carbohydrate Ingestion on Substrate Oxidation Patterns of Males and Females During Running Bouts at the Individual Anaerobic Threshold
Background: To date, it remains unclear how pre-exercise CHO availability modulates the oxidative regulation of substrates when exercise is…

Background The objective of this study was to evaluate the influence of two kinds of plantar short foot muscles exercise on foot posture an…
Neuromodulation of Aerobic Exercise—A Review
Running, and aerobic exercise in general, is a physical activity that increasingly many people engage in but that also has become popular a…
Relationship between cytokines and running economy in marathon runners
Background Running economy (RE), expresses the relationship between the energy cost of running (Cr) and the work performed by a runner and …
Performance and energy systems contributions during upper-body sprint interval exercise
This study investigates energy system contributions in upper-body sprint interval exercise.
Betalain-Rich Concentrate Supplementation Improves Exercise Performance in Competitive Runners
This study aimed to determine the effects of a betalain-rich concentrate (BRC) of red beets, containing antioxidant and anti-in ammatory pr…
The Association Analysis between ACE and ACTN3 Genes Polymorphisms and Endurance Capacity in Young Cross-Country Skiers: Longitudinal Study
Endurance performance depends on the integration of several phenotypic traits influenced by multiple environmental and genetic factors. Obj…
