Abstract
Gonçalves, DS, Moscaleski, LA, da Silva, GM, Morgans, R, Okano, AH, and Moreira, A. The effect of combined transcranial direct current stimulation and pneumatic compression as part of a comprehensive recovery strategy in professional male top-level soccer players. J Strength Cond Res 38(9): 1658–1666, 2024—This retrospective study aimed to examine the effect of transcranial direct current stimulation (tDCS) combined with lower limb pneumatic compression during the postmatch recovery period in top-level professional male soccer players' physiological and perceptual markers of recovery status. During the 2022 season (baseline), pneumatic compression was performed as part of the recovery strategy, applied the day after official match play and psychophysiological measurements (pain, sleep, perceived recovery, and creatine kinase [CK] sampling) were performed on the second day postmatch. During the 2023 season, the tDCS protocol was introduced, with its application being performed simultaneously (in conjunction) with pneumatic compression. Recovery sessions following 10 matches in the 2022 season and following 10 matches in the 2023 season were included in the analyses. Compared with 2022 (baseline; pneumatic compression isolated), the players perceived an increased recovery on the second day postmatch when tDCS was used in conjunction with the pneumatic compression (mean = 12%; p = 0.008) and rated improved sleep quality for the nights after applying tDCS combined with pneumatic compression (mean = 7.5%; p = 0.029). On the second day postmatch, a significant reduction was observed in muscle pain/soreness (mean = 64%; p < 0.0001) and the CK concentration decreased when baseline (pneumatic compression isolated) was compared with tDCS + pneumatic compression (mean = 76%; p = 0.001). In summary, combining pneumatic compression with tDCS may enhance the effects of both interventions, leading to greater overall improvements in recovery. Further research is warranted to confirm these findings and explore the underlying mechanisms in more detail.

Abstract
Fourel, L, Touzard, P, Fadier, M, Arles, L, Deghaies, K, Ozan, S, and Martin, C. Relationships between force-time curve variables and tennis serve performance in competitive tennis players. J Strength Cond Res 38(9): 1667–1674, 2024—Practitioners consider the role of the legs in the game of tennis as fundamental to achieve high performance. But, the exact link between leg actions and high-speed and accurate serves still lacks understanding. Here, we investigate the correlation between force-time curve variables during serve leg drive and serve performance indicators. Thirty-six competitive players performed fast serves, on 2 force plates, to measure ground reaction forces (GRF). Correlation coefficients describe the relationships between maximal racket head velocity, impact height, and force-time curve variables. Among all the variables tested, the elapsed time between the instants of maximal vertical and maximal anteroposterior GRF (r = −0.519, p < 0.001) and the elapsed time between the instant of maximal anteroposterior GRF and ball impact (r = −0.522, p < 0.001) are the best predictors of maximal racket velocity. Maximal racket head velocity did not significantly correlate with the mean or maximal vertical GRF or with the mean or maximum rate of vertical force development. The best predictor for impact height is the relative net vertical impulse during the concentric phase (r = 0.772, p < 0.001). This work contributes to a better understanding of the mechanical demands of tennis serve motion and gives guidelines to improve players preparation and performance. Trainers should encourage their players to better synchronize their upward and forward pushing action during the serve to increase maximal racket head velocity. Players should also aim to improve their relative net vertical impulse to increase impact height through strength training and technical instructions.

Abstract
Techmanski, BS, Kissick, CR, Loturco, I, and Suchomel, TJ. Using barbell acceleration to determine the 1 repetition maximum of the jump shrug. J Strength Cond Res 38(8): 1486–1493, 2024—The purpose of this study was to determine the 1 repetition maximum (1RM) of the jump shrug (JS) using the barbell acceleration characteristics of repetitions performed with relative percentages of the hang power clean (HPC). Fifteen resistance-trained men (age = 25.5 ± 4.5 years, body mass = 88.5 ± 15.7 kg, height = 176.1 ± 8.5 cm, relative 1RM HPC = 1.3 ± 0.2 kg·kg−1) completed 2 testing sessions that included performing a 1RM HPC and JS repetitions with 20, 40, 60, 80, and 100% of their 1RM HPC. A linear position transducer was used to determine concentric duration and the percentage of the propulsive phase (P%) where barbell acceleration was greater than gravitational acceleration (i.e., a>−9.81 m·s−2). Two 1 way repeated measures ANOVA were used to compare each variable across loads, whereas Hedge's g effect sizes were used to examine the magnitude of the differences. Concentric duration ranged from 449.7 to 469.8 milliseconds and did not vary significantly between loads (p = 0.253; g = 0.20–0.39). The P% was 57.4 ± 7.2%, 64.8 ± 5.9%, 73.2 ± 4.3%, 78.7 ± 4.0%, and 80.3 ± 3.5% when using 20, 40, 60, 80, and 100% 1RM HPC, respectively. P% produced during the 80 and 100% 1RM loads were significantly greater than those at 20, 40, and 60% 1RM (p < 0.01, g = 1.30–3.90). In addition, P% was significantly greater during 60% 1RM compared with both 20 and 40% 1RM (p < 0.01, g = 1.58–2.58) and 40% was greater than 20% 1RM (p = 0.003, g = 1.09). A braking phase was present during each load and, thus, a 1RM JS load was not established. Heavier loads may be needed to achieve a 100% propulsive phase when using this method.

Abstract
Hogg, JA, Barger, NB, Bruce, JR, White, CC, Myer, GD, and Diekfuss, JA. Improved quadriceps torque production with optimized biofeedback in patients after anterior cruciate ligament reconstruction. J Strength Cond Res XX(X): 000–000, 2024—Optimizing performance through intrinsic motivation and attention for learning: prevention rehabilitation exercise play (OPTIMAL PREP) training strategies incorporate motor learning principles to enhance movement acquisition and retention. We aimed to use OPTIMAL PREP biofeedback to evaluate its potential to improve quadriceps and hamstring torque production in patients with anterior cruciate ligament reconstruction (ACL-R). Thirteen subjects 23 ± 19 months post ACL-R completed 5 concentric quadriceps/hamstrings repetitions on an isokinetic dynamometer for each limb and counterbalanced condition at 60°·s−1. For the control condition, subjects were instructed to perform the exercise “as hard and fast as possible.” For the OPTIMAL PREP condition, subjects were additionally told that “Research shows that if you focus on moving the line on the screen (external focus) you will exhibit greater quadriceps output (enhanced expectancies)” and were given the choice of graphical representation for the biofeedback (autonomy support). Quadriceps and hamstrings peak torque, rate of force development, and torque-angle waveforms were analyzed with 2 × 2 RMANOVAs (a priori

>0.06). The ACL-R limb demonstrated increased quadriceps peak torque in the OPTIMAL PREP condition than in the control condition (

= 0.13, interaction p = 0.21, pairwise Cohen's d = 0.63). Anterior cruciate ligament reconstruction limb quadriceps deficits remained near terminal extension (14–45°; peak Cohen's d = 0.57, p < 0.001). For hamstrings peak torque, we observed moderate effects for condition (OPTIMAL PREP greater;

= 0.10, p = 0.29) and limb (uninvolved greater;

= 0.13, p = 0.22). Easily implementable OPTIMAL PREP training strategies improved ACL-R limb quadriceps torque production, resulting in between-limb parity. However, asymmetries still existed near terminal extension.
A LITERATURA INFANTIL EM PERIGO: POLÍTICAS PÚBLICAS E O CONTROLE DA LEITURA

Published: July 2024

Neste artigo, propõe-se uma reflexão sobre a concepção de literatura dos editais do Programa Nacional do Livro e do Material Didático – PNLD Literário 2018 e 2020, por meio da análise de seus protocolos de leitura. Apresenta-se ainda um breve percurso histórico da literatura infantil, para melhor compreendermos suas características e transformações. Dessa forma, realiza-se pesquisa bibliográfica e documental, tendo como fundamentação teórica as abordagens historiográficas de Marisa Lajolo, Regina Zilberman, Nelly Novaes Coelho, Edmir Perrotti e Rildo Cosson. Os critérios referentes à qualidade literária estabelecidos pelo programa valorizam uma concepção pedagógica que cerceia a autonomia dos professores, promove um controle da ficção (e, consequentemente, da recepção) e desfigura a obra literária, vetando sua condição estética. Em relação à materialidade das obras, o programa impõe a padronização das características gráfico-editoriais dos livros, o que revela uma concepção desmaterializada da literatura, promove o apagamento e desvalorização dos profissionais envolvidos na elaboração de tais projetos (como ilustradores, designers e editores) e ainda reforça a aproximação do livro literário às cartilhas e materiais paradidáticos.
Reproductive hormones and sex differences in relation to brachial-ankle pulse wave velocity in obese subjects: a retrospective case–control study
Authors: Lin Yunting , Song Endi , Jin Han , Jin Yong 
Published: July 2024

Background
Reproductive hormones may be a risk factor for cardiovascular disease (CVD), but their influence is often underestimated. Obesity can exacerbate the progression of CVD. Arterial stiffness (AS) is correlated with the risk of CVD. Brachial-ankle pulse wave velocity (baPWV) has served as a practical tool for assessing AS with broad clinical applications. This study aimed to investigate the association between reproductive hormones and baPWV in obese male and female subjects.

Methods
A retrospective case–control design was designed. AS was assessed using baPWV, with a baPWV ≥ 1400 cm/s indicating increased AS. Between September 2018 and October 2022, 241 obese subjects with increased AS were recruited from Ningbo Yinzhou No. 2 Hospital. The control group consisted of 241 obese subjects without increased AS. A 1:1 propensity score matching was performed to correct potential confounders by age and sex. We additionally performed a sex-based sub-analysis.

Results
Correlation analysis demonstrated that luteinizing hormone (LH) (r = 0.214, P = 0.001) and follicle-stimulating hormone (FSH) (r = 0.328, P < 0.001) were positively correlated with baPWV in obese male subjects. In the multivariate conditional logistic regression analysis, FSH (OR = 1.407, 95% CI = 1.040–1.902, P = 0.027) rather than LH (OR = 1.210, 95% CI = 0.908–1.612, P = 0.194) was independently and positively associated with increased AS in obese male subjects. However, there was no significant correlation between reproductive hormones and baPWV in women.

Conclusions
Our study identified FSH as a potential risk factor for arteriosclerosis in obese male subjects. This provides a novel and intriguing perspective on the pathogenesis of CVD in obese subjects.
SPERNER THEOREMS FOR UNRELATED COPIES OF POSETS AND GENERATING DISTRIBUTIVE LATTICES
Authors: Czédli Gábor 
Published: July 2024

For a finite poset (partially ordered set) \(U\) and a natural number \(n\), let \(S(U,n)\) denote the largest number of pairwise unrelated copies of \(U\) in the powerset lattice (AKA subset lattice) of an \(n\)-element set. If \(U\) is the singleton poset, then \(S(U,n)\) was determined by E. Sperner in 1928; this result is well known in extremal combinatorics. Later, exactly or asymptotically, Sperner's theorem was extended to other posets by A.P. Dove, J.R. Griggs, G.O.H. Katona, D.J. Stahl, and W.T.Jr. Trotter. We determine \(S(U,n)\) for all finite posets with 0 and 1, and we give reasonable estimates for the "\(V\)-shaped" 3-element poset and, mainly, for the 4-element poset with 0 and three maximal elements. For a lattice \(L\), let \(G_{\min}L\) denote the minimum size of generating sets of \(L\). We prove that if \(U\) is the poset of the join-irreducible elements of a finite distributive lattice \(D\), then the function \(k\mapsto G_{\min}{D^k}\) is the left adjoint of the function \(n\mapsto S(U,n)\). This allows us to determine \(G_{\min}{D^k}\) in many cases. E.g., for a 5-element distributive lattice \(D\), \(G_{\min}{D^{2023}}=18\) if \(D\) is a chain and \(G_{\min}{D^{2023}}=15\) otherwise. The present paper, another recent paper, and a 2021 one indicate that large direct powers of small distributive lattices could be of interest in cryptography.

Key Points

The predictive performance of an African ancestry–specific polygenic risk score (PRS) was comparable to a European ancestry–derived PRS for kidney traits.However, multi-ancestry PRSs outperform single-ancestry PRSs in Black American populations.Predictive accuracy of PRSs for CKD was improved with the use of race-free eGFR.

Background
CKD is a risk factor of cardiovascular disease and early death. Recently, polygenic risk scores (PRSs) have been developed to quantify risk for CKD. However, African ancestry populations are underrepresented in both CKD genetic studies and PRS development overall. Moreover, European ancestry–derived PRSs demonstrate diminished predictive performance in African ancestry populations.

Methods
This study aimed to develop a PRS for CKD in Black American populations. We obtained score weights from a meta-analysis of genome-wide association studies for eGFR in the Million Veteran Program and Reasons for Geographic and Racial Differences in Stroke Study to develop an eGFR PRS. We optimized the PRS risk model in a cohort of participants from the Hypertension Genetic Epidemiology Network. Validation was performed in subsets of Black participants of the Trans-Omics in Precision Medicine Consortium and Genetics of Hypertension Associated Treatment Study.

Results
The prevalence of CKD—defined as stage 3 or higher—was associated with the PRS as a continuous predictor (odds ratio [95% confidence interval]: 1.35 [1.08 to 1.68]) and in a threshold-dependent manner. Furthermore, including APOL1 risk status—a putative variant for CKD with higher prevalence among those of sub-Saharan African descent—improved the score's accuracy. PRS associations were robust to sensitivity analyses accounting for traditional CKD risk factors, as well as CKD classification based on prior eGFR equations. Compared with previously published PRS, the predictive performance of our PRS was comparable with a European ancestry–derived PRS for kidney traits. However, single-ancestry PRSs were less predictive than multi-ancestry–derived PRSs.

Conclusions
In this study, we developed a PRS that was significantly associated with CKD with improved predictive accuracy when including APOL1 risk status. However, PRS generated from multi-ancestry populations outperformed single-ancestry PRS in our study.

Authors: Cuevas Alpuche Juan Osvaldo , Diaz García Luisa , Aguilar Anzures Roberto Jesús , Ramos Zúñiga José Antonio , Sánchez Sagastegui Fabian 
Published: July 2024

INTRODUCCIÓN: La vejiga hiperactiva (VH) es la disfunción miccional más común en la edad pediátrica, con una prevalencia de 5-20% en niños de 5 a 10 años de edad. El tratamiento con anticolinérgicos produce tasas de éxito muy variables y con bajo apego por los efectos colaterales.
OBJETIVO: Conocer la evolución clínica con la terapia de electro estimulación transcutánea sacra (siglas en inglés: TENS) en pacientes con VH.
MATERIAL Y MÉTODOS: Estudio de cohorte retrospectivo de pacientes con diagnóstico de VH que recibieron tratamiento con TENS transcutánea en la región sacra.
RESULTADOS: Se incluyeron 19 pacientes con VH, 12 femeninos y 7 masculinos, con seguimiento de 12 a 32 meses. 13 de los 19 casos, recibieron tratamiento previo con anticolinérgicos y/o toxina botulínica tipo A. La polaquiuria y la incontinencia de urgencia diurna mejoraron en 100% y 87.5% respectivamente. El estreñimiento crónico se corrigió completamente en todos los casos con laxante y TENS. En la enuresis asociada a VH la respuesta al TENS fue baja.
CONCLUSIONES: Los síntomas de VH muestran buena respuesta a la TENS en región sacra, sin efectos colaterales indeseables. La combinación de un laxante con TENS, parece mejorar la respuesta al estreñimiento. La TENS debe considerarse una mejor opción que los anticolinérgicos en el manejo inicial de niños con VH pues carece de efectos colaterales. En la enuresis asociada a VH, la respuesta es baja con TENS. Protocolos con mayor número de casos son necesarios para confirmar los resultados aquí mostrados.
