Twenty-four Weeks of β-Alanine Supplementation on Carnosine Content, Related Genes, and Exercise
SKELETAL MUSCLE CARNOSINE CHRONIC β-ALANINE SUPPLEMENTATION CARNOSINE-RELATED GENES HIGH-INTENSITY CYCLING CAPACITY MUSCLE BIOPSY
2018/4/24
Introduction Skeletal muscle carnosine content can be increased through β-alanine (BA) supplementation, but the maximum increase achievable with supplementation is unknown. No study has investigated t...
Effects of Histidine and β-alanine Supplementation on Human Muscle Carnosine Storage
CARNOSINE LOADING ERGOGENIC SUPPLEMENTS SKELETAL MUSCLE METABOLISM
2018/4/24
Purpose Carnosine is a dipeptide composed of β-alanine and L-histidine and is present in skeletal muscle. Chronic oral β-alanine supplementation can induce muscle carnosine loading and is therefore se...
Sex differences in the effect of fish-oil supplementation on the adaptive response to resistance exercise training in older people: a randomized controlled trial
aging exercise fatty acids muscle sarcopenia
2018/11/12
Background: Resistance exercise increases muscle mass and function in older adults, but responses are attenuated compared with younger people. Data suggest that long-chain n–3 polyunsaturated fatty ac...
The effect of acute vs chronic magnesium supplementation on exercise and recovery on resistance exercise, blood pressure and total peripheral resistance on normotensive adults
Magnesium supplementation Blood pressure Bench press
2015/7/30
Magnesium supplementation has previously shown reductions in blood pressure of up to 12 mmHg. A positive relationship between magnesium supplementation and performance gains in resistance exercise has...
Glutathione supplementation suppresses muscle fatigue induced by prolonged exercise via improved aerobic metabolism
Glutathione Dkeletal muscle Lipid metabolism
2015/7/30
Glutathione is an endogenous redox couple in animal cells and plays important roles in antioxidant defense and detoxification, although it is unknown if oral glutathione supplementation affects exerci...
Ergogenic effects of caffeine and sodium bicarbonate supplementation on intermittent exercise performance preceded by intense arm cranking exercise
Fatigue Blood lactate Rating of perceived exertion
2015/7/30
Caffeine and sodium bicarbonate ingestion have been suggested to improve high-intensity intermittent exercise, but it is unclear if these ergogenic substances affect performance under provoked metabol...
The effect of turmeric (Curcumin) supplementation on cytokine and inflammatory marker responses following 2 hours of endurance cycling
Immunity Interleukins Natural polyphenols
2015/7/30
Endurance exercise induces IL-6 production from myocytes that is thought to impair intracellular defence mechanisms. Curcumin inhibits NF-κB and activator protein 1, responsible for cytokine transcrip...
Does creatine supplementation improve the plasma lipid profile in healthy male subjects undergoing aerobic training?
healthy male subjects aerobic training
2015/7/14
Subjects (n = 22) were randomly divided into two groups and were allocated to receive
treatment with either creatine monohydrate (CR) (~20 g·day-1 for one week followed by ~10 g·day-
1 for a further...
Brain serotonin and dopamine modulators, perceptual responses and endurance performance during exercise in the heat following creatine supplementation
Brain serotonin dopamine modulators
2015/7/14
The present experiment examined the responses of peripheral modulators and
indices of brain serotonin (5-HT) and dopamine (DA) function and their association with
perception of effort during prolong...
Effect of Creatine Supplementation on Muscle Damage and Repair Following Eccentrically-Induced Damage to the Elbow Flexor Muscles
Creatine loading muscle damage muscle force muscle soreness
2015/5/13
We investigated effects of creatine (Cr) supplementation (CrS) on exercise-induced muscle damage. Untrained males and females (N = 27) ages 18-25, with no CrS history in the past 4 months, were random...
Pre-Workout Carbohydrate Supplementation does not Affect Measures of Selfassessed Vitality and Affect in College Swimmers
Nutrition swimmers mood
2015/5/7
Beneficial effects of dietary carbohydrate (CHO) on physical and psychological parameters have been demonstrated in athletes. Because affect, or mood, can predict athletic performace, the main objecti...
