BDNF, metabolic risk factors, and resistance training in middle-aged individuals.
BDNF levels correlated with risk factors for MetS and were elevated in individuals with HiMF and should be added to other nonpharmacological interventions for middle-aged individuals with hiMF such as aerobic and/or diet.
Effect of CHO ingestion on exercise metabolism and performance in different ambient temperatures.
The data demonstrate that, during prolonged exercise in the heat, fatigue is related to factors other than CHO availability, and during exercise in 5 degrees C a 7% CHO solution is more beneficial for exercise performance than a 14%CHO solution.
Effect of creatine supplementation on sprint exercise performance and muscle metabolism.
It was demonstrated that CrS increased muscle total Cr content, but the increase did not induce an improved sprint exercise performance or alterations in anaerobic muscle metabolism.
Alkalosis increases muscle K+ release, but lowers plasma [K+] and delays fatigue during dynamic forearm exercise
Alk was associated with improved regulation of K+, Na+, Cl− and Lac−, and the lower circulating [K+] and greater muscle K+ uptake, Na+ delivery and Cl− uptake with Alk are all consistent with preservation of membrane excitability during exercise.
Psychophysiological stress in elite golfers during practice and competition.
Within-subject analysis revealed elite golfers experienced elevated cortisol, heart rate, cognitive and somatic anxiety, and lower self-confidence during competition compared to practice, but none of these predicted performance.
Fatigue depresses maximal in vitro skeletal muscle Na(+)-K(+)-ATPase activity in untrained and trained individuals.
This study investigated whether fatiguing dynamic exercise depresses maximal in vitro Na(+)-K(+)-ATPase activity and whether any depression is attenuated with chronic training. Eight untrained (UT),
