Strength exercise and training in postprandial lipaemia.
Authors: Silva Correa C, Rebolledo Cobos RC, Reischak-Oliveira Á
Abstract
The development of cardiovascular diseases (CVD) has been associated to alterations on lipid profile as well found during postprandial period, phenomenon known as postprandial lipaemia (PL). Physical exercise is currently the major non-pharmacological intervention used to prevention and reduction of risk factors to developing of CVD. For this reason, there is growing interest under the effects of physical exercise, especially strength training, on regulation and balance of lipid metabolism, particularly of risk groups such as post-menopausal...

Effects of the menstrual cycle on oxidative stress and antioxidant response to high-intensity intermittent exercise until exhaustion in healthy women.
CONCLUSIONS: In women with regular menstrual cycle, oxidative stress during exercise and recovery may be eliminated during the LP, when the estradiol and progesterone levels are higher, compared with those during the FP.

The impact of menstrual-cycle phase on basal and exercise-induced hormones, mood, anxiety and exercise performance in physically-active women.
CONCLUSIONS: The data suggest that physically-active women present a significant change in tension and aerobic performance, which might be linked to temporal changes in sal- E2 concentrations. Moreover, both aerobic and anaerobic exercise can be an option to reduce negative mood during the early-FP.

Biological age, testosterone, and estradiol as discriminating factors of muscle strength levels in young athletes.
CONCLUSIONS: That hormonal concentrations are reliable in discriminating ULS and LLS of young athletes of both sexes. BA was shown to be effective in discriminating ULS (in both sexes) and LLS (in males). BA showed significant reliability with hormonal analyzes (ULS and LLS in male sex; LLS for female sex).

Clinical Concerns on Sex Steroids Variability in Cisgender and
Transgender Women Athletes
Int J Sports Med DOI: 10.1055/a-1909-1196In the female athletic community, there are several endogenous and exogenous
variables that influence the status of the hypothalamus-pituitary-ovarian axis
and serum sex steroid hormones concentrations (e. g.,
17β-estradiol, progesterone, androgens) and their effects. Moreover,
female athletes with different sex chromosome abnormalities exist
(e. g., 46XX, 46XY, and mosaicism). Due to the high variability of sex
steroid hormones serum concentrations and responsiveness, female athletes may
have different intra- and inter-individual biological a...

Resistance Training and Ovariectomy: Antagonic Effects in Mitochondrial Biogenesis Markers in Rat Skeletal Muscle
This study aimed to investigate the effects of ovariectomy, resistance training, and estradiol replacement on markers of mitochondrial biogenesis and protein expression related to oxidative capacity in the rat gastrocnemius pool. Estradiol replacement was performed using Silastic® capsules. During the 12-week resistance training, animals climbed a ladder with weights attached to their tails. Gene expression was analysed by RT-PCR, and protein content was determined by western blotting. Ovariectomy decreased the gene expression of the mitochondrial biogenesis markers PGC-1α (~73%), NRF-1 (~44%), and TFAM (~53%) (p<0.05...

Serum Brain-derived Neurotrophic Factor Levels Mirror Bone Mineral Density in Amenorrheic and Eumenorrheic Athletes
This study investigated the associations between serum BDNF, estradiol, and bone mineral density (BMD) in female athletes. This study included 160 elite female athletes (21.7±4.3 years). Serum levels of BDNF and estradiol were in 195 blood samples obtained from 132 eumenorrheic athletes (EA) and 63 amenorrheic athletes (AA). BMD was measured in the radius, lumbar spine, pelvis, and legs using dual-energy X-ray absorptiometry. AA showed significantly lower serum BDNF levels than EA (p=0.017). Serum BDNF levels were positively and significantly associated with both serum estradiol levels (p=0.0004) and the BMD measured at a...

Effects of the Menstrual Cycle on Serum Carnitine and Endurance Performance of Women
This study aimed to investigate the effect of the menstrual cycle on serum carnitine and the endurance performance of healthy women. Fifteen eumenorrheic women underwent cycle ergometer exercise at 60% maximal oxygen uptake (V̇ O2max) for 45 min, followed by exercise at an intensity that was increased to 80% V̇ O 2max until exhaustion, during two menstrual cycle phases, including the early follicular phase (FP) and the midluteal phase (LP). The blood levels of estradiol, progesterone, total carnitine, free carnitine, and acylcarnitine were assessed. Compared with the FP, the LP had significantly lower serum total carni...

Contemporaneous and temporal interrelationships between menstrual fluctuations in sex hormones and DXA estimates of body composition in a premenopausal female: a case study
CONCLUSIONS: The menstrual profiling of a premenopausal female revealed interrelationships between body composition and water content, but sex hormone fluctuations did not correlate with TBW, FM and LST on the same day or following day in the hypothesized direction. The temporal between- and within-hormone linkages reflect those natural feedback loops that control hormone secretion.PMID:34109946 | DOI:10.23736/S0022-4707.20.11757-2
