Acute hormonal responses to two different fatiguing heavy-resistance protocols in male athletes.
1993
To examine endogenous hormonal responses to heavy-resistance exercise, ten male strength athletes performed two fatiguing but different types of sessions on separate days. In session A the loads for the leg extensor muscles in the squat-lift exercise were maximal so that the subjects performed 20 sets at 1 repetition maximum (RM) (20 x 1 RM x 100%), whereas during session B the loads were submaximal (70%) but the subjects performed each of the 10 sets until the RM (i.e., 10 repetitions/set or 10 x 10 x 70%). The recovery time between the sets was always 3 min. A decrease of 10.3 +/- 4.7% (P < 0.001) occurred in the squat-lift in 1 RM during session A, whereas session B led to a decrease…
Maximal strength and power, muscle mass, endurance and serum hormones in weightlifters and road cyclists.
2004
Maximal strength, power, muscle cross-sectional area, maximal and submaximal cycling endurance characteristics and serum hormone concentrations of testosterone, free testosterone and cortisol were examined in three groups of men: weightlifters (n = 11), amateur road cyclists (n = 18) and age-matched controls (n = 12). Weightlifters showed 45-55% higher power values than road cyclists and controls, whereas the differences in maximal strength and muscle mass were only 15% and 20%, respectively. These differences were maintained when average power output was expressed relative to body mass or relative to muscle cross-sectional area. Road cyclists recorded 44% higher maximal workloads, whereas …
Central obesity and hypertensive renal disease: association between higher levels of BMI, circulating transforming growth factor beta1 and urinary al…
2004
OBJECTIVE: In this study, the relationship between circulating transforming growth factor beta1 (TGFbeta1) and urinary albumin excretion (UAE) has been investigated in non-obese and central obese hypertensive patients. DESIGN AND PATIENTS: Fifty-eight consecutive hypertensive outpatients both lean and with central obesity were enrolled and divided in three groups, according to their body mass index (BMI) values. Group A: 16 lean hypertensives (men with BMI or = 25 kg/m2 and 24.7 kg/m2 and or = 30 kg/m2 and women with BMI > or = 27.3 kg/m2). MEASURES: In all patients, UAE, by immunonephelometric assay, circulating TGFbeta1 by a solid-phase specific sandwich enzyme-linked immunosorbent assay …
Altered endocannabinoid-dynamics in craniopharyngioma patients and their association with HPA-axis disturbances.
2021
Objective Patients with craniopharyngioma (CP) frequently suffer from morbid obesity. Endocannabinoids (ECs) are involved in weight gain and rewarding behavior but have not been investigated in this context. Design Cross-sectional single-center study. Methods Eighteen patients with CP and 16 age- and sex-matched controls were included. Differences in endocannabinoids (2-arachidonoylglycerol (2-AG) and N-arachidonoylethanolamine (AEA)) and endocannabinoid-like molecules (oleoyl ethanolamide (OEA), palmitoylethanolamide (PEA), and arachidonic acid (AA) were measured at baseline and following endurance exercise. We further explored ECs-dynamics in relation to markers of HPA-axis activity (ACT…
Therapeutic synergism between hyaluronic acid and dexamethasone in the intra-articular treatment of osteoarthritis of the knee: a preliminary open st…
1992
In vitro studies on the effects of dexamethasone on human synovial cells have shown that with high concentrations of the steroid in the culture medium cellular activity was completely blocked whereas with low concentrations (10(-6)M), cellular density decreased but there was an increase in the synthesis of RNA, DNA, protein and hyaluronic acid. These data, coupled with clinical experience of using intra-articular hyaluronic acid to treat patients with osteoarthritis of the knee, prompted the investigators to carry out an open, randomized study of the use of very small doses of dexamethasone in association with hyaluronic acid in 40 osteoarthritic patients. Twenty patients received a weekly …
High-Intensity Interval Resistance Training (HIRT) influences resting energy expenditure and respiratory ratio in non-dieting individuals
2012
Abstract Background The benefits of exercise are well established but one major barrier for many is time. It has been proposed that short period resistance training (RT) could play a role in weight control by increasing resting energy expenditure (REE) but the effects of different kinds of RT has not been widely reported. Methods We tested the acute effects of high-intensity interval resistance training (HIRT) vs. traditional resistance training (TT) on REE and respiratory ratio (RR) at 22 hours post-exercise. In two separate sessions, seventeen trained males carried out HIRT and TT protocols. The HIRT technique consists of: 6 repetitions, 20 seconds rest, 2/3 repetitions, 20 secs rest, 2/3…
Plasma catecholamine responses to four resistance exercise tests in men and women
1999
The plasma adrenaline ([A]) and noradrenaline ([NA]) concentration responses of nine men and eight women were investigated in four resistance exercise tests (E80, E60, E40 and E20), in which the subjects had to perform a maximal number of bilateral knee extension-flexion movements at a given cycle pace of 0.5 Hz, but at different load levels (80%, 60%, 40% and 20% of 1 repetition maximum, respectively). The four test sessions were separated by a minimal interval of 3 rest days. The number of repetitions (Repmax), the total work (Wtot) done normalized for the lean body mass and the heart rate (HR) responses were similar in the two groups in each test. In addition, no differences were found b…
Long-term weight loss maintenance after inpatient psychotherapy of severely obese patients based on a randomized study: predictors and maintaining fa…
2006
Abstract Objective The objective of this study was to identify predictors of long-term weight loss after inpatient psychodynamic or behavioral psychotherapy of severely obese patients. Methods In a longitudinal study, obese patients [body mass index (BMI)≥35 kg/m2] were randomly assigned to behavioral or psychodynamic inpatient treatment. The average treatment duration was 7 weeks. Two hundred sixty-seven obese patients, mostly female (85%), with psychiatric and somatic comorbidity (age, 20–64 years; BMI=35–74 kg/m2) were examined with standardized self-report scales at intake, discharge, 1-year follow-up, and 3-year follow-up. Results Overall, 3 years after inpatient psychotherapy, irrespe…
Associations between long-term physical activity, waist circumference and weight gain: a 30-year longitudinal twin study.
2007
Background and objective: Physical activity level and obesity are both partly determined by genes and childhood environment. To determine the associations between long-term leisure-time physical activity, weight gain and waist circumference and whether these are independent of genes and childhood effects. Design and subjects: The study design is a 30-year follow-up twin study in Finland. For this study, 146 twin pairs were comprehensively identified from the large Finnish Twin Cohort. These twin pairs were discordant for both intensity and volume of leisure physical activity in 1975 and 1981 and were healthy in 1981. At follow-up in 2005, both members of 89 pairs were alive and participated…
Resistance Training Induces Antiatherogenic Effects on Metabolomic Pathways
2019
INTRODUCTION Arising evidence suggests that resistance training has the potential to induce beneficial modulation of biomarker profile. To date, however, only immediate responses to resistance training have been investigated using high-throughput metabolomics whereas the effects of chronic resistance training on biomarker profile have not been studied in detail. METHODS A total of 86 recreationally active healthy men without previous systematic resistance training background were allocated into (i) a resistance training (RT) group (n = 68; age, 33 ± 7 yr; body mass index, 28 ± 3 kg·m) and (ii) a non-RT group (n = 18; age, 31 ± 4 yr; body mass index, 27 ± 3 kg·m). Blood samples were collecte…
