Neuromuscular adaptations and serum hormones in females during prolonged power training.
1990
Training-induced adaptations in the neuromuscular and endocrine systems were investigated in seven females during prolonged power type strength training. Great (p less than 0.05) changes occurred primarily during the earlier weeks of the 16-week training especially in the time of force production (from 161 +/- 107 to 93 +/- 65 ms to produce a 500 N force) and, correspondingly, in the average forces in the earlier positions of the (absolute) force-time curve of the leg extensor muscles. These changes were accompanied by significant (p less than 0.05) increases in the neural activation of the trained muscles in the earliest positions of the IEMG-time curve. Hypertrophic changes, as judged fro…
Serum basal hormone concentrations, nutrition and physical fitness during strength and/or endurance training in 39-64-year-old women.
2009
We examined effects of 21 weeks of strength and/or endurance training and nutrition on serum hormones and physical fitness in 39-64-year-old women. Subjects (n=79) were randomized into the endurance group (E), strength group (S), combined group (SE) and controls (C). Total body strength training and high-intensity bicycle training were used. Average energy and nutrient intake remained the same in all groups. Body fat (dual energy X-ray absorptiometry) decreased significantly in all training groups and body mass index in E, SE and C. Only SE increased total body lean mass (2.2%, p=0.001), between groups p=0.044. Maximal cycling power increased more in E (16%) and SE (17%) than in S (8%)(all …
Self-Reported Long-Term Autonomic Function After Laparoscopic Total Mesometrial Resection for Early-Stage Cervical Cancer: A Multicentric Study.
2017
ObjectivesThis multicentric retrospective study investigates the early and long-term self-reported urinary, bowel, and sexual dysfunctions in early-stage cervical cancer patients who submitted to laparoscopic total mesometrial resection (L-TMMR), total laparoscopic radical hysterectomy, vaginal-assisted laparoscopic radical hysterectomy, and laparoscopic-assisted radical vaginal hysterectomy.MethodsCervical cancer patients, FIGO (International Federation of Gynecology and Obstetrics) stage IA2–IB1/IIA1 who submitted to nerve-sparing radical hysterectomy were recruited. Pelvic functions were assessed within 30 days (early outcome) and 12 months after surgery (long-term outcome).ResultsTwo hu…
Assessing Causality in normal and impaired short-term cardiovascular regulation via nonlinear prediction methods
2009
We investigated the ability of mutual nonlinear prediction methods to assess causal interactions in short-term cardiovascular variability during normal and impaired conditions. Directional interactions between heart period (RR interval of the ECG) and systolic arterial pressure (SAP) short-term variability series were quantified as the cross-predictability (CP) of one series given the other, and as the predictability improvement (PI) yielded by the inclusion of samples of one series into the prediction of the other series. Nonlinear prediction was performed through global approximation (GA), approximation with locally constant models (LA0) and approximation with locally linear models (LA1) …
Neuromuscular adaptations and serum hormones in women during short-term intensive strength training
1992
The effects were investigated in ten women of intensive heavy resistance strength training lasting for 3 weeks on electromyographic (EMG) activity, muscle cross-sectional area (CSA) and voluntary force production characteristics of leg extensor muscles. Blood samples for the determinations of serum hormones were taken from five of the subjects. Significant increases occurred in the higher force portions of the isometric force-time curve with an increase of 9.7 (SD 8.4)% (P less than 0.01) in maximal peak force. An increase of 15.8 (SD 20.9)% (P less than 0.05) took place also in the maximal neural activation (integrated EMG) of the trained muscles, while an enlargement of 4.6 (SD 7.4)% (P l…
Use of the Martius advancement flap for low rectovaginal fistulas
2019
Aim: The percentage recurrence after any surgical treatment for low rectovaginal fistula (LRVF) is unacceptably high. The aim of this study was to evaluate the short- and long-term results of the Martius procedure in a carefully selected series of patients with a LRVF of at least 1 cm diameter who had had at least two previous surgeries or in the presence of chronically inflamed local tissues. Method: Between January 2009 and April 2017, 24 patients with the abovementioned features were prospectively included in this study. Success was defined both as the absence of any subjective symptoms and the fistula, as confirmed by evaluation under anaesthesia. Postoperative complications were assess…
Sexual Function and Fertility of Women with Classic Bladder Exstrophy and Continent Urinary Diversion
2015
We evaluated the outcome in female patients with classic bladder exstrophy and continent urinary diversion for sexual function and fertility.We reviewed the medical records of female exstrophy patients who underwent continent urinary diversion in our department between 1969 and 2014. Patients were invited for followup examination and asked to complete questionnaires relating to sexual function, social integration and maternity.Of 38 eligible patients 29 (response rate 76%) with a followup of 22.3 years were included in study. Primary continent urinary diversion was done in 62% of patients and 38% underwent secondary continent urinary diversion after failed reconstruction of the exstrophic b…
Effects of intra-session exercise sequence during water-based concurrent training.
2013
The aim was to investigate the effects of the intra-session exercise order during water-based concurrent training on the neuromuscular adaptations in young women. 26 women (25.1±2.9 years) were placed into 2 groups: resistance prior to (RA) or after (AR) aerobic training. Subjects performed resistance (sets at maximal effort) and aerobic training (exercises at heart rate corresponding to the second ventilatory threshold) twice a week over 12 weeks, performing both exercise types in the same training session. Upper (elbow flexion) and lower-body (knee extension) one-repetition maximum test (1RM) and peak torque (PT) were evaluated. The muscle thickness (MT) of upper (sum of MT of biceps brac…
Relationship between Thyroid Status during the First Trimester of Pregnancy and Neonatal Well-Being
2021
Iodine is an essential micronutrient for the synthesis of thyroid hormones. The proper functioning of the thyroid axis is essential for the normal development of the nervous system, especially in the first trimester of gestation. The aim of the present study was to analyze the perinatal outcomes, anthropometry, and APGAR test scores of newborns and to relate them to maternal thyroid status. A total of 190 newborns participated in the study. No correlation was found between thyroid stimulating hormone (TSH) and maternal ioduria values in the first trimester of gestation with the weight or length of the newborn, or the APGAR score at one minute after birth. However, we found significant diffe…
Improvement of phonemic fluency following leftward prism adaptation.
2021
AbstractAnatomo functional studies of prism adaptation (PA) have been shown to modulate a brain frontal-parieto-temporal network, increasing activation of this network in the hemisphere ipsilateral to the side of prism deviation. This effect raises the hypothesis that left prism adaptation, modulating frontal areas of the left hemisphere, could modify subjects’ performance on linguistic tasks that map on those areas. To test this hypothesis, 51 healthy subjects participated in experiments in which leftward or rightward prism adaptation were applied before the execution of a phonemic fluency task, i.e., a task with strict left hemispheric lateralization onto frontal areas. Results showed tha…
