Abstract
Ghanati, HA, Letafatkar, A, Almonroeder, TG, and Rabiei, P. Examining the influence of attentional focus on the effects of a neuromuscular training program in male athletes. J Strength Cond Res 36(6): 1568–1575, 2022—Neuromuscular training programs that incorporate lower extremity strengthening, plyometric exercises, balance training, and movement retraining are recommended for anterior cruciate ligament injury prevention; however, there is a need to improve their effectiveness. The purpose of this study was to examine how athletes' attentional focus during training influences the effects of an 8-week neuromuscular training program on hip strength, single-leg landing mechanics, and hop performance. Sixty-six male athletes were randomly allocated to a group that trained with an internal focus, a group that trained with an external focus, or a control group. All athletes completed testing before (baseline) and after (posttesting) the 8-week period. Isokinetic hip strength, hip and knee kinematics and ground reaction forces during landing, and hop distance were examined as part of this study. Analysis of covariance was used to compare posttesting outcomes among the groups while accounting for group differences in baseline performance. The neuromuscular training program resulted in improved hip abduction strength, reduced hip adduction and internal rotation motion during landing, and increased hop distance for athletes who trained with an external focus. However, the program did not seem to influence hip strength, landing kinematics, or hop performance for athletes who trained with an internal focus. Our findings indicate that male athletes may benefit from completing a neuromuscular training program with an external focus vs. an internal focus. Trainers, coaches, and clinicians should consider using instructions that promote an external focus when implementing neuromuscular training programs with male athletes.

Abstract
Terada, K, Kikuchi, N, Burt, D, Voisin, S, and Nakazato, K. Full title: Low-load resistance training to volitional failure induces muscle hypertrophy similar to volume-matched, velocity fatigue. J Strength Cond Res 36(6): 1576–1581, 2022—We investigated how resistance training (RT) to failure at low load affects acute responses and chronic muscle adaptations compared with low-load RT to velocity fatigue at equal work volume. Twenty-seven subjects performed 8 weeks of bench press twice weekly. Subjects were randomly assigned to one of 3 groups: low-load volitional failure (LVoF, n = 9), low-load velocity fatigue (LVeF, n = 8), and high-load (HL, n = 10). Resistance training comprised 3 sets to failure at 40% one repetition maximum (1RM) in the LVoF group, 3 sets to velocity fatigue (20% lifting velocity loss) at 40% 1RM in the LVeF group, and 3 sets of 8 repetitions at 80% 1RM in the HL group. We measured muscle strength, hypertrophy, endurance, and power at baseline and after the RT program. We also measured muscle swelling and blood lactate after each RT bout to investigate the acute response. There were no differences in total work volume between the LVoF and LVeF groups. Responses to RT were similar between LVoF and LVeF, whether looking at acute muscle swelling, increase in blood lactate, chronic hypertrophy, and strength gain. However, LVoF and LVeF RT triggered different responses to muscle function in comparison with HL training: LVoF and LVeF showed enhanced acute responses and greater chronic endurance gains, but lower chronic strength gains than HL. In conclusion, low-load RT to volitional failure induces muscle hypertrophy similar to volume-matched velocity fatigue.

Abstract
Loturco, I, McGuigan, MR, Rodríguez-Rosell, D, Pereira, LA, and Pareja-Blanco, F. A novel strategy to determine the 1-repetition maximum in the jump squat exercise. J Strength Cond Res 36(8): 2330–2334, 2022—This study aimed to determine the maximum relative load of the half-squat (HS; i.e., % HS 1-repetition maximum [1RM]) that can be used in its ballistic variation, namely, the jump squat (JS) exercise, and to examine whether this reference value varies in subjects with different strength levels. In total, 186 elite athletes from 10 distinct sport disciplines participated in this study. A progressive loading test up to HS 1RM was performed during the competitive phase of the season for all athletes. Mean propulsive velocity and propulsive phase duration were also assessed during the 1RM test. Athletes were divided into 3 distinct subgroups: “low,” “middle,” and “high” strength levels, based on their relative HS 1RM values (kg·kg−1). A 1-way analysis of variance was used to compare the variables assessed between the groups. Significance level was set at p < 0.05. The high group demonstrated the highest relative HS 1RM values, followed by the middle and low groups (all p < 0.05). No significant differences were observed between the groups for the remaining variables (p > 0.05). It was observed that at 86.0 ± 5.4% 1RM, the full concentric action can already be considered as entirely propulsive in the HS exercise for all subjects, independent of their strength levels. Therefore, this relative strength value may be used as a reference for the 1RM in the JS exercise.

Koyama, T, Rikukawa, A, Nagano, Y, Sasaki, S, Ichikawa, H, and Hirose, N. Acceleration profile of high-intensity movements in basketball games. J Strength Cond Res 36(6): 1715–1719, 2022—This study aimed to elucidate movements that require greater acceleration during basketball games, their occurrence frequency, and compare acceleration components. Eighteen male collegiate basketball players (age: 19.5 ± 0.8 years) were enrolled. Triaxial accelerometer was used to measure acceleration and a synchronized video was recorded. Moments that generated resultant accelerations >4, 6, and 8 G, and their coincided movements were identified. Ratios and frequencies of the extracted movements were calculated and Jonckheere-Terpstra trend test was used to examine which movement rate increased when acceleration threshold increased. In addition, the top 7 movements that generated a resultant acceleration >6 G among the combination of basketball-specific movements were extracted. Their resultant, mediolateral, vertical, and anteroposterior accelerations were identified and compared using one-way analysis of variance. Cohen's d was used to calculate effect sizes. All p < 0.05 were considered statistically significant. The extracted frequencies were 33.6, 9.1, and 2.3 cases per minute for >4 G, >6 G, and >8 G, respectively. As the threshold increased, the rate of deceleration, landing, and physical contact increased. The mediolateral acceleration of physical contact was significantly greater than other movements, whereas the vertical acceleration of landing and deceleration was significantly greater than other movements. Thus, acceleration component analysis was performed to classify movement types. Greater acceleration appeared frequently in movement during defense. It is suggested that many defense movements involve a reaction to the ball and opponent. There are many passive movements during defense and speed changes rapidly. If many passive movements occur when defending, larger physical load is applied, and may lead to fatigue.

Abstract
García-Pinillos, F, Lago-Fuentes, C, Bujalance-Moreno, P, and Pérez-Castilla, A. Effect of the menstrual cycle when estimating 1 repetition maximum from the load-velocity relationship during the bench press exercise. J Strength Cond Res 36(3): e55–e58, 2022—This study aimed to examine the effect of the ovulatory menstrual cycle (MC) when estimating the 1 repetition maximum (1RM) from the individual load-velocity relationship during the bench press (BP) exercise. Nine resistance-trained eumenorrheic women (age: 28.7 ± 3.6 years) were tested in 3 different phases across the MC: menstrual or early follicular phase (i.e., testing between days 1–3), follicular or late follicular phase (i.e., testing between days 7–10), and luteal or mid-luteal phase (i.e., testing between days 19–21). Each testing trial consisted of an incremental loading protocol against 4 loading conditions (≈50-70-80-90% 1RM) in the concentric-only BP exercise. A smartphone application (MyLift) was used to collect the mean velocity (MV) of all repetitions. The 1RM was estimated from the individual load-velocity relationship by applying a linear regression model as the load associated with an MV of 0.17 m·s−1. In addition, the MV obtained at each %1RM (i.e., from 20% 1RM to 80% 1RM in 20% increments), the load-velocity slope (i.e., the decrease in MV per each 1% of increment in the %1RM), and the y-intercept (i.e., the estimate of MV at 0% 1RM) were computed from the individual load-velocity relationships. No significant differences were observed between the 3 phases of the MC for any of the measured load-velocity relationship parameters (corrected p-value ≥0.495; effect size ≤0.24). The results suggest that the estimation of the BP 1RM from the load-velocity relationship seems not to vary over the 3 different phases of the MC (i.e., menstrual, follicular, and luteal phases).

Abstract
Heileson, JL, Peterson, M, Adair, KE, and Funderburk, LK. Comparison of a sucrose-based and rice-based sports beverage on hydration status during a 19.3-km foot march in ROTC cadets. J Strength Cond Res 36(4): 1105–1110, 2022—The purpose of this field study was to determine whether a rice-based sport beverage (RB) maintains hydration status compared to a sucrose-based sports beverage (SB) during a load-bearing 19.3-km foot march. Eighteen Reserve Officer Training Corps (ROTC) cadets (male, n = 11; female, n = 7) were randomly assigned to consume either 2.84 L of an RB (carbohydrate, 114 g; sodium, 1306 mg) or SB (carbohydrate, 170 g; sodium, 1136 mg) throughout the duration of the foot march (temperature 14.44° C, humidity 50%). The sports beverages were distributed once before the event and then every 3.2 km for a total of 6 servings (0.47 L each). Pre- and post-urine specific gravity (USG) and body mass were used to assess hydration status. A survey was used to determine subjective ratings of perceived exertion and gastrointestinal (GI) discomfort. The level of significance was set at p < 0.05 for all analyses. Sixteen cadets completed the study. Based on USG, both beverages significantly improved hydration status (USG = 1.017 ± 0.010 pre-march vs. 1.011 ± 0.008 post-march, p = 0.04); however, there was no difference between groups (change in USG = −0.009 ± 0.012 for RB group vs. −0.003 ± 0.008 for SB group, p = 0.92). Ratings for perceived exertion and GI discomfort scores were similar between groups. In conclusion, the RB was as effective as the SB at maintaining hydration status and could potentially reduce GI discomfort. Athletes and military personnel concerned with ensuring appropriate hydration during moderate-intensity endurance events can achieve similar fluid balance from a rice-based sports beverage that is lower in calories, carbohydrate, and sugar.

Abstract
Dudley, CE, Drinkwater, EJ, and Feros, SA. Different cluster-loading protocols have no effect on intraset and interset power expression. J Strength Cond Res 36(7): 1763–1769, 2022—This study investigated the effect of cluster-loading protocols on changes in hang power clean (HPC) power characteristics. Ten trained weightlifters (7 male, 3 female, HPC 1.28 [M]; 1.03 [F] × body mass) completed 4 experimental protocols in a randomized repeated-measures design. Protocols were traditional, a basic cluster, and 2 undulating clusters. Each protocol comprised 3 sets of 5 HPC repetitions at an average of 70% 1 repetition maximum (RM). The load for undulating cluster protocols ranged between 60 and 80% 1RM. Countermovement jumps (CMJs) were performed before and after each protocol to gauge effect on neuromuscular status. Statistical analysis comprised a one-way repeated measures analysis of variance. Peak power was significantly greater in the fifth repetition of the basic cluster set protocol compared with the traditional set protocol (mean ± SD: 6.6 ± 2.8%, p = 0.043, g = 0.25). Neither undulating load protocol significantly altered set power characteristics compared with basic cluster sets; however, when analyzing repetition data, peak power increased as load increased (and vice versa), indicating the prescribed loads were suboptimal for power expression in this sample. There was no change in CMJ height between protocols. Coaches should prescribe inter-repetition rest to maintain peak power across multiple repetitions and sets. Basic cluster protocols seem to be the most practical choice over undulating cluster protocols because there is no need to adjust load between repetitions.
Fatigue Behavior of Thick-Walled Nodular Cast Iron Containing Dross
Authors: Bleicher Christoph 
Published: August 2020

Abstract
In large castings made of nodular cast iron, dross is not easy to detect with nondestructive testing (NDT) methods and reduces the static and cyclic fatigue strength of the material significantly, as shown in the example in figure 1. This causes a significant amount of work in foundries in removing dross or rejecting the complete component if a secure assessment of the component’s lifetime cannot be given. The aim of the reported work was thus to find appropriate methods to determine the characteristics of dross, such as its stiffness and density, in thick-walled nodular cast iron and to set up an assessment concept for the lifetime determination of components affected by dross. For the investigations, large cast blocks of EN-GJS-400-15 were cast with fields of dross in the upper side of the blocks. These blocks were investigated with different NDT methods, such as mechanized ultrasonic testing and magnetic particle inspection, to obtain information on the position and the characteristics of the dross. Subsequently, fatigue specimens and tensile specimens were removed from the cast blocks from the dross regions and from the baseline material without dross and were tested under strain control to determine the cyclic strain-based material behavior of the different specimens, with varying forms of dross. Additionally, all fatigue specimens were investigated with regard to their dross distribution using X-ray computer tomography, sulfur tests, and magnetic particle inspection. During the investigations, special attention was paid to the material stiffness, because this is significantly influenced by dross. Also, previous results on shrinkages in nodular cast iron showed good correlation between the material stiffness and the density measured in the specimen’s test volume. This correlation offers a link to NDT and a possibility to assess the influence of dross on the local fatigue strength.

Published: August 2020

Se presenta un caso de un hombre de 31 años con fractura de fémur. Los estudios complementarios mostraron una imagen compatible con lesión quística. El primer estudio por biopsia de dicho quiste informó erróneamente un quiste simple. Se realizó una osteosíntesis con enclavado endomedular. El paciente tuvo una evolución tórpida asociada a imágenes líticas diafisarias y pérdida de la reducción de la fractura. Se retiró el material y se tomaron muestras del canal endomedular, cuyo cultivo reveló Pseudomonas aeruginosa y restos de quistes hidatídicos en la anatomía patológica. En nuestro centro, fue tratado por una seudoartrosis infectada secundaria a un quiste óseo hidatídico complicado. Se le colocó un megaespaciador de cemento con antibiótico y, luego, una prótesis total de fémur como tratamiento definitivo. El compromiso óseo es muy raro y de difícil diagnóstico, y puede llevar a una diseminación severa. Si bien no hay consenso ni tratamiento de elección para los casos graves, el reemplazo femoral total en dos tiempos representa una opción alentadora para conservar el miembro, con resultados satisfactorios a corto y mediano plazo.

Polish Slaves and Captives in the Crimea in the Seventeenth Century
Authors: Kizilov Mikhail 
Published: August 2020

AbstractThe article examines the history of the trade in Polish slaves and captives in the Tatar and Ottoman Crimea in the seventeenth century on the basis of hitherto unknown archival evidence and rare printed sources. After the capture an average Polish slave of simple origin was transported to the Crimea, where he had been sold on the local slave markets. Unless he had some special qualifications, a slave usually had to fulfil agricultural duties and do heavy manual work. The slaves usually had some limited free time and could attend Catholic services in the churches of the Crimea's large urban centres. Rich Polish captives were treated in accordance with their high social status and were ransomed for a considerable redemption fee. Important role in ransoming such rich captives was played by Jewish, Tatar and Armenian merchants.

Molybdenum dosage and application timing in sweet corn
Authors: Cecílio-Filho Arthur Bernardes , López-Aguilar Miguel Angel , Rugeles-Reyes Sergio Manuel , Mendoza-Cortez Juan Waldir 
Published: August 2020

Nowadays, there is a greater offer of sweet corn hybrids with a high productive potential, shorter cycle and more intense metabolism than common corn, resulting in this crop being very demanding in terms of nutrients. The present study aimed to evaluate the effect of three levels of molybdenum (Mo) (150, 300 and 450 g ha-1), via foliar spraying, with different application timing (E1: 100% at 15 days after emergence - DDE; E2: 100% at 30 DDE; E3: 100% at 45 DDE; E4: 50% at 15 and 30 DDE, and E5: 33.3% at 15, 30 and 45 DDE) on the agronomic performance of sweet corn ‘SVN 9298’. There was a significant effect from the interaction of the factors on the foliar concentration of Mo, obtaining the highest value with 450 g ha-1 of Mo, applied at 45 DDE, with an increase of 1.2% in the foliar content from that observed in the plants without a Mo application. Also, the foliar concentration of nitrogen (N) was higher with the highest Mo level. The highest number of commercial ears (49,583), total productivity of ears (20,942 kg ha-1) and productivity of commercial ears (13,211 kg ha-1) were obtained with estimated levels of 316, 450 and 311 g ha-1 of Mo, respectively. Likewise, the dose that maximized grain productivity (5,055 kg ha-1), which is the most important component that defines the agronomic performance of sweet corn, was the estimated dose of 334 g ha-1 of Mo.
