Successful training not only must involve overload but also must avoid the combination of excessive overload plus inadequate recovery. Athletes can experience short-term performance decrement without severe psychological or lasting other negative symptoms. This functional overreaching will eventually lead to an improvement in performance after recovery.(More)
The aim of this study was to address the effect of endurance training on tissue sensitivity to glucocorticoids (GC) in both resting and exercising conditions. In vitro dexamethasone inhibition of LPS-induced interleukin-6 secretion in cultures of peripheral monocytes was compared in untrained subjects (UT) and in endurance-trained men (ET) at the end of a(More)
OBJECTIVE This study was conducted to obtain a detailed profile of hypothalamo-pituitary-adrenal (HPA) axis activity and reactivity and its differential relationships with body fat distribution and total fat mass in premenopausal obese women. RESEARCH METHODS AND PROCEDURES Cortisol responses to stimulation (awakening, food intake, exercise) and(More)
The hypothalamo-pituitary-adrenal axis is involved throughout the exercise-recovery cycle. Nevertheless, differences in hormone responses during early recovery between sedentary and endurance trained subjects are not well known. The aim of this preliminary study was to monitor plasma cortisol and adrenocorticotropic hormone (ACTH) concentrations both during(More)
The aim of the present study was to investigate the effects of training variations on 24-hr urinary noradrenaline (NA) and adrenaline (Ad) levels and the adrenaline/noradrenaline (Ad/NA) ratio to search for a possible relationship between catecholamine excretion, training, and performance in highly trained swimmers. Fourteen swimmers (5 female and 9 male)(More)
BACKGROUND The benefit of protein supplementation on the adaptive response of muscle to exercise training in older people is controversial. OBJECTIVE To investigate the independent and combined effects of a multicomponent exercise program with and without a milk-based nutritional supplement on muscle strength and mass, lower-extremity fatigue, and(More)
AIM Fat mass localization affects lipid metabolism differently at rest and during exercise in overweight and normal-weight subjects. The aim of this study was to investigate the impact of a low vs high ratio of abdominal to lower-body fat mass (index of adipose tissue distribution) on the exercise intensity (Lipox(max)) that elicits the maximum lipid(More)
AIM This study compared the effect of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) for 16 weeks on whole-body and abdominal fat mass (FM) in postmenopausal women with type 2 diabetes (T2D). METHODS Seventeen women (69±1 years; BMI: 31±1kg.m-2) were randomly assigned to either a HIIT [60×(8s at 77-85% HRmax, 12s(More)
The purpose of this study was to examine the effect of a recovery period between two periods of exercise on bone metabolism and related hormones. Concentrations of serum parathyroid hormone ([PTH]), plasma ionized calcium ([Ca(2+)]) and total calcium were measured. A group of 12 healthy men aged 20-27 years participated in this study. They took part in two(More)
BACKGROUND Except immediate freezing of the samples, no practical method has been validated for preservation of glucocorticoids and catecholamines in 24-h urine collection. Furthermore, the influence of urine storage at bladder temperature during periods of different lengths and the effect of prior exercise on preservation of these hormones in the bladder(More)
