Abstract
Willingham, BD, Daou, M, VanArsdale, J, Thomas, M, and Saracino, PG. Energy availability in female collegiate beach volleyball athletes. J Strength Cond Res XX(X): 000–000, 2024—Low energy availability (LEA) is a present risk for many female athletes. Yet, the literature on LEA is often reliant on single, short-term, snapshots, which may not be reflective of the chronic energy balance surrounding female athletes in sport. Therefore, the purpose of this study was to establish the current prevalence of LEA in female collegiate beach volleyball athletes during the preseason and across the competitive season. One-way repeated measures analysis of variance was used to compare measures of EA (i.e., dietary intake, activity energy expenditure [EE], body composition) and EE (i.e., resting metabolic rate and thermic effect of feeding) at 4 timepoints—once in the preseason (i.e., Fall), and 3 times across the 10-week competitive season in Spring (i.e., week 1, week 5, and week 9). Significance was set at p ≤ 0.05. Although mean EA was in the subclinical zone (i.e., 30–45 kcal·kg FFM−1·d−1) at each timepoint, the prevalence of LEA for individuals was 30.8% in the preseason, 37.5% at week 1, 25.0% at week 5, and 62.5% at week 9. Further, carbohydrate intake was below the recommended range for power athletes at each timepoint, suggesting that female beach volleyball athletes with LEA may benefit from increasing carbohydrate intake. Despite no statistical differences in body mass across the season (p = 0.577), there was a trend for increasing fat-free mass (p = 0.062) as the season progressed. Importantly, LEA is not a team-wide condition but an individual one. Therefore, approaches to mitigate LEA should be individualized.

Grammenou, M, Kendall, KL, Wilson, CJ, Porter, T, Laws, SM, and Haff, GG. Effect of fitness level on time course of recovery after acute strength and high-intensity interval training. J Strength Cond Res XX(X): 000–000, 2024—The aim was to investigate time course of recovery after acute bouts of strength (STR) and high-intensity interval training (HIIT). A secondary goal was to assess the influence of total fitness score (TFS), composed of handgrip strength and maximum aerobic power on recovery. Twenty-eight resistance-trained individuals completed 8 testing sessions within a 14- to 17-day period. Subjects performed a testing battery comprising isometric midthigh pull (IMTP), countermovement jump (CMJ), and a modified Wingate test (WINmod) at baseline, immediately after exercise, as well as at 6 and 24 hours after the training sessions. A one-way ANOVA was performed to examine time changes after the training sessions. Subjects were then grouped based on their TFS in high, medium, and low groups. To examine the influence of TFS on time course of recovery, we performed a linear mixed-effects model. Statistical significance was set at p < 0.05. Both training sessions resulted in a significant reduction in peak force (PF) that persisted for up to 6 (p < 0.05) and 24 hours (p < 0.001). The STR session showed immediate and 24-hour postexercise declines in jump height and reactive strength index modified (RSImod) compared with baseline. The low TFS group exhibited a significant RSImod reduction immediately after HIIT (p < 0.001), compared with the medium TFS group (p = 0.0002). In the STR session, the high TFS group displayed an increased eccentric displacement during CMJ 24 hours after exercise compared with baseline (p = 0.033). Overall, subjects with high TFS may be able to recover CMJ performance at the same rate as other TFS groups, despite performing more work.

Abstract
Edwards, AM, Coleman, D, Fuller, J, Kesisoglou, A, and Menting, SGP. Time perception and enjoyment of professional soccer players in different training sessions: Implications for assessment of session-RPE and training load. J Strength Cond Res XX(X): 000–000, 2024—The purpose of this study was to investigate whether the perception of time and enjoyment levels among professional soccer players varied according to the type of training undertaken and whether this influenced the training load (TL) assessment method of session-rating of perceived exertion (sRPE). Sixteen male professional soccer players participated in this study. A diverse range of 7 training events was sampled, comprising passive sessions (e.g., long and short video analysis sessions; VA1 & VA2), sport-specific game play (small-sided games), physical tactical sessions (tactical formation training), individual skills training, and cardiovascular training sessions (long and short; CV1 & CV2). Sessions varied in duration. Subjects estimated duration, enjoyment, and perceived exertion. The activities rated as most enjoyable (all physical training sessions with the exception of CV1 & CV2) were also the sessions considered to last shortest, or time perceived as running fastest (P < 0.01). Long-duration video analysis (VA2) and high-intensity cardiovascular training (without a ball) (CV2) were rated least enjoyable (P < 0.01) and were the sessions where time estimates were longer than chronological time, indicating time perceived as running slow (P < 0.01). Differences in subjective and chronological estimates of sRPE substantially impacted TL estimates across the 5 physically active sessions (P < 0.01). The outcomes of this study indicate that systematic and task-specific variations in time perception and enjoyment exist among professional soccer players. This could be impactful for training design, optimizing the training experience, and reliably assessing TL.

Abstract
Larsen, S, Zee, Md, and Tillaar, Rvd. The impact of stance width on kinematics and kinetics during maximum back squats. J Strength Cond Res XX(X): 000–000, 2024—This study compared the lower extremity peak net joint moments (NJMs) and muscle forces between wide and narrow stance widths defined as 1.7 and 0.7 acromion width in the last repetition of the concentric phase in 3 repetition maximum back squats. Twelve recreationally trained men (age:25.3 ± 2.9 years, height:179 ± 7.7 cm, body mass:82.8 ± 6.9 kg) volunteered for the study. The NJMs were estimated using inverse dynamics and individual muscle forces with static optimization. The main findings of interest were that the wide stance resulted in statistically smaller knee flexion angles (Cohen's d: 0.9; 95% confidence interval [CI]: −17.96 to −3.18°), knee extension NJMs [d: 1.45; 95% CI: −1.56 to −0.61 Nm·kg−1], and vastii forces [d: 1.3; 95% CI: −27.7 to −0.9.5 N·kg−1] compared with the narrow stance. Moreover, we observed significantly larger hip abduction angles [d: 3.8; 95% CI: 12.04 to 16.86°] for the wide stance. Hence, we suggest that recreationally trained men aiming to optimize muscle forces in the vastii muscles during maximum back squat training should consider adopting a narrow stance.

Synaptically released zinc is a neuronal signaling system that arises from the actions of the presynaptic vesicular zinc transporter protein ZnT3. Mechanisms that regulate the actions of zinc at synapses are of great importance for many aspects of synaptic signaling in the brain. Here, we identify the astrocytic zinc transporter protein ZIP12 as a candidate mechanism that contributes to zinc clearance at cortical synapses. We identify small molecule compounds that antagonize the function of ZIP12 in heterologous expression systems, and we use one of these compounds, ZiMo12.8, to increase the concentration of ZnT3-dependent zinc at synapses in the brain of male and female mice to inhibit the activity of neuronal AMPA and NMDA glutamate receptors. These results identify a cellular mechanism and provide a pharmacological toolbox to target the molecular machinery that supports the actions of synaptic zinc in the brain.Significance StatementSynaptic zinc is loaded into presynaptic glutamatergic vesicles by the protein zinc transporter 3 (ZnT3), where it is co-released with glutamate during synaptic transmission. Evidence from clinical studies in humans shows that alterations in the expression of the neuronal zinc transporter protein ZnT3 and the astrocytic zinc transporter protein ZIP12 are associated with schizophrenia, suggesting that dysregulation of these brain-specific zinc transporter proteins may contribute altered synaptic signaling in the brain. Our results show that ZIP12 protein is expressed by astrocytes at synapses in the brain. We identify pharmacological agents that inhibit ZIP12 and we use them to modulate zinc levels in the brain. This research advances our understanding of the roles of synaptic zinc in health and disease.
The inviolability and value of the human body and the corpse in the Islamic legal tradition
Authors: Lee Dana 
Published: January 2025

This article examines how the inviolability (hurma) of the human body is conceived of and negotiated within juristic discourses on the paradigmatic hypothetical case of the starving person from the fifth/eleventh through seventh/thirteenth centuries. The Islamic legal tradition documents lively juristic discussions and debates on hypothetical cases of necessity, many of which implicate foundational questions of value and the inviolability of the human body. At a basic level, necessity applies to a situation in which someone must ‘break’ the law or fail to fulfill a legal obligation, in order to escape the threat of serious harm to something of high value (usually, life, limb, or health). The jurists constructed multiple hypothetical cases of necessity that implicate the inviolability of the human body, including the cases of the starving person, excision of gangrenous tissue, and cesarian section, as well as numerous fact patterns of coercion. This article considers the challenging issues of inflicting serious bodily harm on others and on oneself in order to preserve life, including inflicting harm on the living and on the dead, as well as self-harm. It provides an account and analysis of both the substance and mechanics of fiqh argument, or how jurists reasoned through complex questions of value that also have substantial bases in conceptions of the human body, medicine, logic, and reasonableness through the language and method of the fiqh. This article argues that the evidence and methods of argumentation employed by the jurists reveal significant diversity and tensions in juristic method and understandings of value and subjectivity in the fiqh, as well as in the construction of the foundational concepts of inviolability (hurma) and (legal) protection ('isma). Furthermore, it shows that in the starving person paradigm, the jurists explored the boundary between (non-human) animality and humanity, and grappled with how to locate the (dead) human body within legal thought, and how to operationalize the higher degree of respect accorded to the human body than to non-human bodies. Finally, it examines the ways in which these discourses provide material for considering the functions of subjectivity, emotions, and moral aversion in the law.

ABSTRACT
The objective of this study is to assess the performance of different path-effect models for developing nonergodic ground motion models (GMMs) using a Turkish ground-motion database. The cell-specific attenuation approach is widely used to capture path effects in the formulation of nonergodic GMMs. However, this approach can mainly capture anelastic attenuation effects associated with the spatial variation of the quality factor, and it is limited in capturing 3D velocity structure effects, which may be, in particular, relevant for long-period ground motions or short-distance and short-period ground motions. Recent efforts have introduced new models to incorporate 3D velocity structure effects; however, the assessment of these models in the context of instrumentally recorded ground motions is limited. This study assesses the performance of three path-effects models for Türkiye. Specifically, we consider the cell-specific attenuation approach and two additional models based on Gaussian processes but with a different parametrization on how they represent the spatial correlation of path effects. The results indicate that the models based on Gaussian processes outperform the cell-specific approach for long-period spectral accelerations and short-period ground motions at short distances, offering significant aleatory standard deviation reductions. The differences between the Gaussian process-based models are also discussed, highlighting how their parameterization is reflected in prediction patterns. This study contributes to the transition from ergodic to nonergodic approaches in performance-based earthquake engineering.

Published: January 2025

Purpose: is to identify the dynamics of mutual influences and risks in the corporate bond markets of Russia, China, and the United States under conditions of external environmental instability.Methods: the methods of comparative and econometric analysis of daily data from 2016 to 2024 were used, including the average yields of short- and medium-term corporate and the government bonds of the Russian Federation, China and the United States, selling prices of gold, oil, exchange rates, refinancing rates. GARCH models for forecasting the volatility of the index of corporate bonds of the Russian Federation and China under the influence of internal and external factors, multidimensional quantile regression for industries of the Russian Federation are calculated.Results: six stages of changes in the dynamics of the corporate bond debt market under the influence of the market itself and external factors were highlighted. Periodization made it possible to study the impact of short-term and long-term effects of shocks on the debt market. For the Russian Federation, the volatility weight of the previous period is more than twice the weight of the long-term average volatility. For China, this ratio is even higher. The debt market of the Russian Federation is influenced by the debt markets of China and the United States, but the opposite has not been proven. Three groups of branches of the Russian economy have been formed according to the generality of reaction to external influences.Conclusions and Relevance: during crisis periods, the weight of long-term average market volatility and local factors increases, while that of external factors decreases. Understanding the interactions of internal and external factors allows investors to anticipate market fluctuations, adapt and protect capital. For the Government, this provides an opportunity to develop scientifically sound risk forecasts and use new financial instruments such as yuan bonds.
An Effectiveness Test Combination of Ethanol Extracts of Buas-buas Leaves (Premna serratifolia L.) and Sappan Wood (Caesalpinia sappan L.) as Topical Antiinflammatory Agent in Male White Rats (Rattus novergicus)
Authors: Isnindar  , Purnamaputra Alfred , Luliana Sri 
Published: January 2025

Background: Inflammation is the reaction of the immune system to tissue damage resulting from physical injury, harmful chemicals, or microbial agents. Steroid and non-steroid drugs are commonly used to treat inflammation, but long-term use can result in side effects, such as hormonal disorders and gastric ulcers. Buas-buas leaves and sappan wood has potential as traditional medicines, and based on empirical evidence, they utilize both plants as anti-inflammatory, antibacterial, antioxidant, antiallergic, and antiarthritic agents, as well as for the treatment of cardiovascular disorders, cough, and leprosy. Objective: This study aimed to evaluate the effect of combining 96% ethanol extracts from buas-buas leaves and sappan wood to deliver topical anti-inflammatory benefits. Methods: This research was experimental, using thirty male rats divided into six treatment groups: a negative control group with 2% carrageenan, Biocream® control group, a positive control group with Hydrocortisone Acetate, and three treatment groups receiving a combination of ethanol extracts from buas-buas leaves and sappan wood at concentrations of 1.67%, 2.5%, and 3.75%. The test compounds were administered after carrageenan injection. Measurement of skinfold thickness on the backs of the rats was conducted every hour for 6 h using digital calipers, and the difference in skinfold thickness of each rat, AUC value, and percentage of inflammation inhibition was calculated. Data analysis involved the Kolmogorov-Smirnov test and Levene's test to assess normality and homogeneity, respectively, and was subsequently followed by One-way ANOVA and a post-hoc test. Conclusion: The combination of ethanol extracts of Buas-Buas leaves and sappan wood can provide a topical anti-inflammatory effect, with the most effective concentration being 3.75% and an inflammation inhibition percentage of 32.77%.

Published: January 2025

ste artículo examina los patrones y niveles de fecundidad según el tipo de unión conyugal y clase socioeconómica entre mujeres colombianas. Se enfoca especialmente el estrechamiento de algunas de las brechas que antes distinguían el comportamiento de la fecundidad en las diferentes clases socioeconómicas. Utilizando los datos de Demographic and Health Survey (DHS) para 1995, 2005 y 2015, se analizan los cambios en el contexto en que ocurre la reproducción que reflejan transformaciones en los valores que guían la formación de la familia, respaldadas por marcos legales. Hubo un aumento generalizado de las uniones libres en todos los grupos sociales a lo largo de las décadas. También se demuestra que las uniones libres pasaron a tener una mayor participación en la Tasa Global de Fecundidad (TGF) en comparación con los matrimonios, siendo ellas responsables del 57,5 % de la fecundidad global colombiana, es decir, un 39,4 puntos porcentuales mayor que la participación de las mujeres casadas en la TGF en el año más reciente. Aparentemente, hay incluso más niños naciendo fuera de uniones de cualquier tipo que dentro del matrimonio.

Archery athletes train their physique and technique in order to perform a series of bow and arrow pulls to the maximum, but athletes who can perform movements well during training may not necessarily be able to do it perfectly during the match. Athletes' concentration can be disrupted by various things when competing and affect the performance and achievements of athletes. The ability to concentrate is something that can be trained through mental training. This study aims to test whether there is an effect of Mindfulness Meditation, as one of the mental training methods, on the concentration of archery athletes. This study uses an experimental method with a pretest-posttest control group design. The subject of this study is 30 athletes from the Unimed Archery Club who are divided into experimental and control groups. The instrument used to measure the concentration of athletes is the Grid Concentration Exercise. Data were obtained by conducting pretest and posttest on both groups. Mindfulness Meditation treatment was given only to the experimental group. The results of the Wilcoxon Test analysis showed that there was a difference in concentration scores between after and before treatment in the experimental group (Sig.=0.027, p<0.05), meaning that the hypothesis "there is an effect of Mindfulness Meditation on concentration in Unimed Archery Club Archery Athletes" was accepted. The experimental group had a higher average gain score than the control group (5.5>0.76), which showed that Meditation Mindfulness had an effect on increasing the concentration of Archery athletes.
