Objective: Anserine, which is abundant in avian species and in a wide range of fish such as bonito and tuna, is reported to have anti-fatigue effect. Although chicken soup and bonito soup is traditionally used to recover from physical fatigue, it is generally difficult to verify the effect in humans. This study was to directly demonstrate the anti-fatigue effect of oceanic anserine in humans. M...

1. The activity of pyruvate dehydrogenase in its active and inactive forms was measured in biopsy samples obtained from the vastus lateralis muscle of healthy subjects before and after exercise. 2. At rest, 40 +/- 4% (mean +/- SEM) of the enzyme was in the active form. 3. After progressive aerobic exercise to exhaustion (n = 5), 88 +/- 2.3% was in the active form. 4. After intermittent supramax...

We sought to determine whether oral contraception alters the gender-related differences observed in the exercise pressor reflex during isometric handgrip exercise. Fifteen men, fifteen normally menstruating women (WomenNM), and fifteen women taking monophasic oral contraceptives (WomenOC) completed two trials of a 3-min isometric handgrip exercise protocol performed at 30% of their maximal volu...

The purpose of this study was to compare an electrostimulated to an active recovery strategy after a submaximal isometric fatiguing exercise. Nineteen healthy men completed three sessions (separated by at least 4 weeks) which included a knee extensors provocation exercise consisting of 3 sets of 25 isometric contractions. Contraction intensity level was fixed respectively at 60%, 55% and 50% of...

OBJECTIVE To investigate the benefit of intensive dynamic exercises in comparison to range of motion (ROM) and isometric exercises in rheumatoid arthritis. METHODS 100 consecutive rheumatoid arthritis patients on stable medication were randomly assigned to (1) intensive dynamic group exercises which included full weight bearing exercises and conditioning exercises on a stationary bicycle whil...

The distribution of the reflex effects of isometric exercise on cutaneous vasomotor and sudomotor function is not clear. We examined the effects of isometric exercise by different muscle masses on skin blood flow (SkBF) and sweat rate (SR) in nonglabrous skin and in glabrous skin. The latter contains arteriovenous anastomoses (AVAs), which cause large fluctuations in SkBF. SkBF was measured by ...

BACKGROUND Aging involves reductions in exercise total limb blood flow and exercise capacity. We hypothesized that this may involve early age-related impairments of skeletal muscle microvascular responsiveness as previously reported for insulin but not for exercise stimuli in humans. METHODS Using an isometric exercise model, we studied the effect of age on contrast-enhanced ultrasound (CEUS)...

BACKGROUND In young people, cardiovagal baroreflex sensitivity alters during isometric exercise. We investigated whether the reduced resting baroreflex sensitivity seen with increasing age is similarly altered during exercise. METHODS Cardiovagal baroreflex sensitivity was examined in 8 young (age+/-SEM, 25+/-1.7 years) and 9 older (61+/-3.0 years) subjects, using sequence analysis during vol...

background: inflammation and pain induced by delayed onset muscle soreness (doms) as a result of eccentric exercise (ee) or unaccustomed activity cause some difficulties in exercise for athletes. the purpose of this study was to survey the effect of ginger extract on biochemical and functional symptom of delayed onset muscle soreness.   methods : in a quasi-experimental study, 36 healthy female...

The purpose of this investigation was to determine if creatine supplementation assisted with reducing the amount of exercise induced muscle damage and if creatine supplementation aided in recovery from exercise induced muscle damage. Two groups of subjects (group 1 = creatine; group 2 = placebo) participated in an eccentric exercise protocol following 7 and 30 days of creatine or placebo supple...
