The response of blood buffering capacity and H+ regulation to three types of recovery during repeated high-intensity endurance training
Background/aim: Many studies were shown the effect of type's recovery on performance. Active recovery has been reported by some to promote greater exercise capacity, while others have not confirmed these results. The aim of this study was to determine the effect of three types of recovery during repeated high-intensity endurance training on blood buffering capacity and H+ regulation. Desig...
متن کاملEffect of HX108-CS supplementation on exercise capacity and lactate accumulation after high-intensity exercise
BACKGROUND In the present study, we determined the effects of HX108-CS (mixed extract of Schisandra chinensis and Chaenomeles sinensis) supplementation on lactate accumulation and endurance capacity. Furthermore, we examined CK (creatine kinase), LDH (lactate dehydrogenase) activity to determine whether the HX108-CS affected markers of skeletal muscle injury in vivo and in vitro. METHODS Exer...
متن کاملDoes low serum carnosinase activity favor high-intensity exercise capacity?
Given the ergogenic properties of β-alanyl-L-histidine (carnosine) in skeletal muscle, it can be hypothesized that elevated levels of circulating carnosine could equally be advantageous for high-intensity exercises. Serum carnosinase (CN1), the enzyme hydrolyzing the dipeptide, is highly active in the human circulation. Consequently, dietary intake of carnosine usually results in rapid degradat...
متن کاملAcute effect of calcium lactate supplementation intake on the performance and buffering capacity of elite amateur boxing athletes
This study aimed to assess the effects of acute calcium lactate supplementation intake on the performance and buffering capacity of elite amateur boxing athletes. 8 elite amateur boxers (180±4.33 cm, 24.12±3.68 years, Weight categories: -75, -64, -69, +81) were assigned to acutely receive calcium lactate (0.5 g, 80 mg calcium lactate/kg body weight) and placebo in a double-blind crossover desig...
متن کاملNutritional Strategies to Modulate Intracellular and Extracellular Buffering Capacity During High-Intensity Exercise
Intramuscular acidosis is a contributing factor to fatigue during high-intensity exercise. Many nutritional strategies aiming to increase intra- and extracellular buffering capacity have been investigated. Among these, supplementation of beta-alanine (~3-6.4 g/day for 4 weeks or longer), the rate-limiting factor to the intramuscular synthesis of carnosine (i.e. an intracellular buffer), has bee...
