The current findings indicated greater performance fatigability during UL versus BL leg extensions, but similar patterns of neuromuscular responses consistent with the Muscle Wisdom Hypothesis.

To determine changes in neuromuscular performance throughout the menstrual cycle in females aged 18-25.
Fifty physically active college females (25 on oral contraceptives (OC)) were recruited to participate. Data collection visits coincided with early-follicular (Fp), ovulatory (Op), and the mid-luteal (Lp) phases. Isokinetic peak torque at the knee (IPT) was measured at 60°/sec, 180°/sec, and 300°/sec. Grip force was measured using a handheld dynamometer. Plasma estradiol and progesterone confirmed menstrual cycle and serum relaxin was screened as a potential covariate.
Grip strength was lower during Fp (30.1±0.7kg) than during Op (31.5±0.7 kg, p=0.003) and Lp (32.6±0.7 kg, p<0.001). IPT at 60°/sec was lower during Fp (83±14 nM) than during the Op (86±15 nM, p=0.02). IPTs at 180°/sec and 300°/sec were lower during Fp than Op and Lp (180°54±10 vs. 58±10 and 61±11 nM [both, p<0.001]; 300° 43±9 vs. 46±9 and 47±9 nM [both<0.001]. The OC group-by-phase interaction was not significant for any of the outcomes.
Results indicate that muscular performance is diminished during Fp and the lack of group-by-phase interaction indicates that this effect is not hormone-related. These data indicate that females may be at a greater risk of injury due to decreased strength during Fp than other phases of their cycle.

Hip development is influenced by mechanical loading, but associations between prenatal loading and hip shape in later life remain unexplored.
We examined associations between prenatal loading indicators (gestation length, oligohydramnios (OH) and breech) obtained from obstetric records and hip shape modes (HSMs) generated using dual-energy X-ray absorptiometry images taken at age 14- and 18-years in participants from the UK Avon Longitudinal Study of Parents and Children (ALSPAC). These associations were examined in 2453 (30 OH, 105 breech) and 2330 (27 OH, 95 breech) participants with complete data at age 14- and 18-years respectively using confounder-adjusted models.
At 14 years HSM2 was 0.59SD lower in OH males, and HSM5 (-0.31SD) and HSM9 (-0.32SD) were lower in OH in both sexes. At 18 years HSM1 (-0.44SD) and HSM2 (-0.71SD) were lower and HSM6 (0.61SD) and HSM8 (1.06SD) were higher in OH males, whilst HSM5 was lower in OH in both sexes. OH appeared to be associated with a wider femoral neck and head, and larger lesser/greater trochanters. Only weak associations were observed between gestation length/breech and HSMs.
These results suggest that prenatal skeletal loading, in particular oligohydramnios, may influence adolescent joint shape with associations generally stronger in males.

Long-acting reversible contraceptive (LARC) methods have been developed to close this gap. The main aim of this study is to identify factors associated with the use of LARCs among women of reproductive age and to examine the relationship between knowledge of LARCs and the current use of LARCs in Nigeria. Methods This study assessed the PMA2020 methodology and secondary dataset using female datasets from PMA 2016 (Round 3) exercise. The survey was conducted out in seven states of Nigeria. The target population for this study was women of reproductive age (15-49 years) currently using contraception prior to the survey. The sample size of women that met the inclusion criteria was 1927. The data were analyzed using frequency distribution, chi-square, and logistic regression at a 5% level of significance. Results The results showed that 21.0% of women were using traditional methods. 14.8% of the sampled women were using LARCs methods. Findings further showed that at both levels of analyses, there is a significant relationship (P less then 0.05 and P=0.00 for binary and logistic regression, respectively) between knowledge of LARCs and the use of LARCs. This means that knowledge of LARCs and socio-demographic variables among women of reproductive age in Nigeria can influence the use of LARCs. Conclusions We concluded in this study that 14.8% of women using contraception were using LARCs. Additionally, the level of education, age of women, household wealth, and the number of living children were significantly associated with using LARCs in Nigeria. Also, when discussing contraception with women, health care practitioners should discuss the risks and benefits of LARCs with women of reproductive age and recommend them as a first-line method.Background The burden of cardiometabolic diseases, including cardiovascular diseases and diabetes, is increasing in sub-Saharan Africa and this has been linked to urbanisation. DMOG Helminths, through their immunomodulatory properties, may protect against these disorders. We hypothesised that the rural environment protects against cardiometabolic diseases and that helminths may influence rural-urban disparity of cardiometabolic disease risk. Methods We compared metabolic parameters of individuals aged ≥10 years living in rural, high-helminth-transmission and urban, lower-helminth-transmission settings in Uganda. Cross-sectional surveys were conducted in rural Lake Victoria island fishing communities and in urban sub-wards in Entebbe municipality. Helminth infection and outcomes, including insulin resistance (computed using the homeostatic model assessment of insulin resistance [HOMA-IR]), fasting blood glucose, fasting blood lipids, blood pressure, body mass index (BMI), waist and hip circumference, were assessed.
