Ramos, GP, Nakamura, FY, Penna, EM, Mendes, TT, Mahseredjian, F, Lima, AM, Garcia, ES, Prado, LS, and Coimbra, CC. Comparison of physical fitness and anthropometrical profiles among Brazilian female soccer national teams from U15 to senior categories. J Strength Cond Res 35(8): 2302–2308, 2021—This study aimed to compare anthropometric and physical fitness of Brazilian female national team soccer players from the U15 to senior categories, and to compare the physical performance between selected and nonselected players. Subjects included 231 athletes (U15, n = 46, U17, n = 49, U20, n = 98, and Senior, n = 38). Body mass, height, sum of skinfolds, squat jump (SJ), countermovement jump (CMJ), 20-m linear sprint, and Yo-Yo IR1 were assessed. The U15 players were shorter than all other groups (p < 0.01) and lighter than U20 players (p < 0.01). Regarding physical tests, Senior athletes presented higher SJ compared with U20, and both showed higher CMJ and SJ compared with the U15 and U17 (p < 0.05). Senior athletes were also faster than players of all other categories in 20-m sprint (p < 0.01) and covered the greatest distance in the Yo-Yo IR1 (p < 0.05). U20 were better in the Yo-Yo IR1 than the younger groups (p < 0.05). When comparing selected and nonselected players, no differences were identified in anthropometric measures (p > 0.05). However, selected players from U17, U20, and Senior teams showed better performance in Yo-Yo IR1 than nonselected ones (p < 0.05). Finally, selected senior athletes also presented higher CMJ and SJ than nonselected players (p < 0.05). These results suggest that, although there is a tendency for maintenance in anthropometric measures from the age of 15 years, there are substantial improvements in speed, lower-body power, and aerobic capacity from U20 age group. In addition, it seems that intermittent aerobic fitness contributes to the selection of players to international tournaments in national teams.

Teixeira, EL, de Salles Painelli, V, Silva-Batista, C, de Souza Barros, T, Longo, AR, Lasevicius, T, Schoenfeld, BJ, Aihara, AY, and de Almeida Peres, B. Blood flow restriction does not attenuate short-term detraining-induced muscle size and strength losses after resistance training with blood flow restriction. J Strength Cond Res 35(8): 2082–2088, 2021—After a short-term resistance training with blood flow restriction (BFR), we investigated the effects of 12 days of detraining (DET), without an exercise stimulus, on quadriceps cross-sectional area (QCSA) and muscle strength (1 repetition maximum [1RM]), with 1 leg receiving daily intermittent BFR during DET vs. the same nonexercise condition without BFR (CON) in the contralateral leg. Both subjects' legs were evaluated for QCSA and 1RM before (PRE) and after (POST) both legs being unilaterally submitted to 3 weeks (4 days per week) of low-load (3 sets of 15 repetitions, 30% 1RM) resistance training with BFR. The DET period started immediately after POST, where each leg was randomly submitted to a daily intermittent BFR protocol or CON, without any associated exercise stimulus. Quadriceps cross-sectional area and 1RM were reassessed after DET. Both legs at CON and BFR conditions increased QCSA (6.3 and 6.8%, respectively; both p < 0.0001) and 1RM (9.5 and 10.1%, respectively; both p < 0.05) from PRE to POST. Both legs at CON and BFR conditions reduced QCSA (−4.6 and 4.9%, respectively; both p < 0.0001) and 1RM (−9.0 and −8.2%, respectively; both p < 0.05) from POST to DET, with no significant differences between conditions (p > 0.05). We conclude that muscle strength and hypertrophy gains obtained in 3 weeks of resistance training with BFR are not maintained after 12 days of DET. Moreover, the application of BFR, without an associated exercise stimulus, does not attenuate such losses.

Costa, BDV, Ferreira, MEC, Gantois, P, Kassiano, W, Paes, ST, de Lima-Júnior, D, Cyrino, ES, and Fortes, LS. Acute effect of drop-set, traditional, and pyramidal systems in resistance training on neuromuscular performance in trained adults. J Strength Cond Res 35(4): 991–996, 2021—The aim of this study was to analyze the acute effects of resistance training (RT) systems on lower- and upper-limb performance in trained adults. Eighteen male young adults with experience in RT aged from 18 to 26 years underwent the 3 experimental conditions (drop-set [DS], decrescent pyramid [DP], and traditional [TR]). The subjects performed 2 exercises (bench press and leg press 45°). In the DS condition, they underwent 2 sets of 10 repetitions at 12RM, followed by 5 additional repetitions with an intensity of 15RM with 6-minute interval rest between sets. In the DP, it was performed 3 sets of 10 repetitions at 10RM, 12RM, and 15RM, respectively, and the rest interval was 3 minutes between sets. In the TR, the subjects performed 3 sets of 10 repetitions at 12RM with 3 minutes of rest between sets. Countermovement jump, peak power (Wpeak), and force (F
peak) in the bench press were evaluated in the baseline, before, and 30 minutes after the experimental sessions. Countermovement jump performance decreased significantly only after the DS and DP conditions (−6.7 and −1.9%, respectively). The groups were significantly different in the post-intervention; the DS condition presented lower values when compared with the DP (p = 0.01) and TR (p = 0.001). According to F
peak and Wpeak, only DS condition significantly decreased the performance (−3.8 and −4.1%, respectively). The results indicate the DS and DP conditions impair the neuromuscular performance of the lower limbs, whereas for upper limbs, only DS condition negatively affect upper-limb performance.

Abstract
Madruga-Parera, M, Bishop, C, Fort-Vanmeerhaeghe, A, Beltran-Valls, MR, Gonzalo-Skok, O, and Romero-Rodríguez, D. Interlimb asymmetries in youth tennis players: relationships with performance. J Strength Cond Res 34(10): 2815–2823, 2020—Change of direction speed (CODS) has been highlighted as a critical component of tennis. Interlimb asymmetries have been commonly studied in jump tests, but less attention given to the topic during CODS. The aim of this study was to quantify interlimb asymmetries in jumping and CODS (during traditional and isoinertial tests) and establish their relationship with measures of physical performance. Twenty-two elite youth tennis players (16.3 ± 1.4 years) performed single-leg countermovement jump (SLCMJ), single-leg broad jump, and single-leg lateral jump, a double 180° turn CODS test, and shuffle lateral step and crossover step with an isoinertial resistance device. Paired-samples t-tests revealed significant differences between limbs for all tests (p < 0.05). Interlimb asymmetry scores ranged from 1.83 to 15.03%, and a 1-way repeated-measures analysis of variance showed significant differences between interlimb asymmetry scores across multiple tests (p < 0.05). Spearman's rank order r correlations showed significant negative relationships between CODS asymmetry and SLCMJ performance on both limbs (r = −0.50; p = 0.02 and r = −0.53; p = 0.01) and CODS performance on both limbs (r = 0.50; p = 0.02 and r = 0.63; p = 0.002). These results show the test-specific nature of asymmetries in youth tennis athletes, with the SLCMJ presenting the greatest magnitude of asymmetry. Furthermore, interlimb differences during CODS were associated with reduced performance during jumping and CODS tests, suggesting the monitoring of asymmetries within this population may therefore be warranted.

de Hoyo, M, Núñez, FJ, Sañudo, B, Gonzalo-Skok, O, Muñoz-López, A, Romero-Boza, S, Otero-Esquina, C, Sánchez, H, and Nimphius, S. Predicting loading intensity measuring velocity in barbell hip thrust exercise. J Strength Cond Res 35(8): 2075–2081, 2021—The barbell hip thrust is an increasingly used exercise to target the hip extensors. Direct and indirect measurement of 1 repetition maximum (1RM) to determine the relative load of each exercise is time-consuming; therefore, practitioners may be more in favor of monitoring velocity and determining relative load through velocity-based prediction models for an exercise. This study aimed to assess the relationship between mean velocity (MV) and mean propulsive velocity (MPV) at different relative training loads (%1RM) in the barbell hip thrust exercise. One hundred two male sport science students performed an incremental 1RM testing protocol for the barbell hip thrust exercise, and a linear position transducer measured MV and MPV of the barbell. The 1RM was reached at 0.25 ± 0.03 m·s−1, and the regression model generated to estimate a relative load showed an acceptable standard error of estimate (7.01 ± 1.05% 1RM and 7.36 ± 1.05% 1RM for MV and MPV, respectively) with a very large explained variance (R
2 = 0.94). These results may have important practical applications for the prescription and monitoring of the accessory exercise of the hip thrust for monitoring training load and predicting 1RM without undertaking a RM test.

Abstract
De Giorgio, A, Iuliano, E, Turner, A, Millevolte, C, Cular, D, Ardigò, LP, and Padulo, J. Validity and reliability of a light-based electronic target for testing response time in fencers. J Strength Cond Res 35(9): 2636–2644, 2021—Response time (RT) is a fencing fundamental sensorimotor skill. Therefore, the aim of the current study was to examine the efficacy of a light-based electronic target in fencers, designed to measure and train this entity. Ninety-five fencers (M = 53; F = 42) were tested in regard to their RT, using a light-based electronic target, for 3 different attack types: simple attack, the lunge, and an attack after a 1.5-m thrust. All subjects were divided into elite vs. novice fencers. Elite fencers had national and international rankings, and were again divided with regard to used weapon: épéeists (n = 32; M = 19; F = 13) and foilists (n = 30; M = 13; F = 17). Measurement was evaluated for validity/reliability, sensitivity/specificity, and correlation. Reliability was high for all attack types (intraclass correlation coefficient 0.94–0.96). Lower RTs were found in males for 2 attack types with good sensitivity (81–93%)/specificity (50–91%) for all attack types. Elite fencers responded faster than novice fencers for all attack types (p < 0.001), whereas elite males were faster than females for 2 attack types (p < 0.01). Lower RTs in females correlated with level for one attack type (r = 0.797, p < 0.05). In conclusion, the light-based electronic target system was found to be highly reliable and therefore could be used by fencing athletes as a further measure of performance.

Abstract
Bertolaccini, AL, da Silva, AA, Teixeira, EL, Schoenfeld, BJ, and de Salles Painelli, V. Does the expectancy on the static stretching effect interfere with strength-endurance performance? J Strength Cond Res 35(9): 2439–2443, 2021—Static stretching (SS) may interfere with strength performance. Such interference, however, may be partially attributed to the subjects' or researcher's expectancy about the SS effects. We aimed to examine whether the manipulation of subjects' expectancy of SS on force production could influence strength-endurance during unilateral knee extension exercise. Eighteen strength-trained men were randomly divided into positively biased (PB; N = 9) or negatively biased (N = 9) groups on the possible effects of SS on performance. Subjects' total number of repetitions and total volume of exercise were assessed during strength-endurance tests (4 sets performed to failure at 70% of 1 repetition maximum) performed under 2 different conditions on separate days: Control—no stretching (CON); or SS. Static stretching consisted of 3 sets of 3 stretching exercises, lasting 30 seconds each. Data were analyzed using mixed models. Neither the total number of repetitions nor the total volume was significantly different between the CON and SS conditions, nor for type of bias (all p > 0.05). However, the number of repetitions in the last set of exercise was greater during SS compared with CON for the PB group (p = 0.01). Although previous negative or positive information about SS did not interfere with the total number of repetitions and total volume of exercise, previous positive information about SS improved performance in the last set of exercise. Expectancy therefore may have played a partial role influencing strength-endurance in previous studies.

Abstract
Furlong, L-AM, Harrison, AJ, and Jensen, RL. Measures of strength and jump performance can predict 30-m sprint time in Rugby Union players. J Strength Cond Res 35(9): 2579–2583, 2021—Performance and fitness monitoring in Rugby Union often include jumping, sprinting, and strength tests, but repeatability of and relationships between these measures are unclear. The level of interindividual variability in these relationships and their sprint time predictive capabilities are also unknown. This study examined the reliability of, and relationship between, countermovement (CMJJH), squat (SJJH), and rebound (RBJJH) jump heights, rebound jump contact time (RBJCT), estimated 1 repetition maximum back squat relative to body mass (SQBM), and reactive strength index (RSI) to 30-m sprint time of subelite, semiprofessional Rugby Union players. Measurement reliability was very good, with high average intraclass correlation coefficients (≥0.9) and low coefficient of variation (<10.1%). All variables were significantly (p < 0.01) correlated to each other (r > 0.575), except for SQBM (only related to CMJJH, r = 0.621) and RBJCT (only related to RSI, r = −0.727). SJJH and SQBM were the strongest and most consistent predictors of time to 30 m (R = 0.754 ± 0.081; SEE = 0.166 ± 0.025), but variability in SEE magnitude was observed across the group during bootstrapping. Cross-validation showed a mean difference between actual and predicted 30 m times equivalent to 0.22% of the group average time to 30 m. These results support the importance of multiple aspects of fitness training in Rugby Union players for improving performance in short-duration sprinting activities, but highlight the individual nature of their relative importance. Measures of strength and power can be used to predict short sprint performance by the strength and conditioning professional.

Published: April 2019

ABSTRACTAmidst the rapid development of English teaching, teacher’s professional development (TPD) is crucial for English teachers. It has been discussed in the TESOL Summit 2018 in Jakarta that the teachers demanded a TPD approach which facilitates them in sharing professional experiences with other teachers. This qualitative research would like to investigate the effectiveness of reflection with critical incident theory (CIT) framework as a form of TPD which many studies have found effective to fulfil that demand and yet, rarely discussed in the context of Indonesia. Based on the reviewed literature, this research applied guided reflection and interview to gather the data. The gathered data were then analysed using open-, axial-, and selective coding. From the triangulated data, five themes related to TPD were extracted. One theme is dedicated to discussing two unique cases. Overall, by reflecting their critical incidents, all of the participants could understand their experience deeper and thus, making it meaningful. Therefore, this research suggests that the utilization of reflection using CIT framework must be investigated further in a bigger scope with bigger participants and more frequencies of reflection. ABSTRAKDi tengah pesatnya perkembangan pengajaran bahasa Inggris, pengembangan profesionalisme guru (TPD) penting bagi guru Bahasa Inggris. Telah didiskusikan dalam TESOL Summit 2018 di Jakarta bahwa para guru menginginkan sebuah pendekatan TPD yang memfasilitasi mereka untuk berbagi pengalaman profesional dengan guru lainnya. Penelitian kualitatif ini ingin menginvestigasi keefektifan refleksi dengan kerangka teori peristiwa kritis (CIT) sebagai bentuk TPD yang mana banyak studi telah menemukan keefektifan untuk memenuhi permintaan tersebut, akan tetapi jarang didiskusikan di dalam konteks Indonesia. Berdasarkan tinjauan pustaka, penelitian ini mengaplikasikan refleksi terpandu dan wawancara untuk mengumpulkan data. Data yang telah terkumpul dianalisis dengan menggunakan open-, axial-, dan selective coding. Dari data yang telah ditriangulasi, terekstrak lima tema terkait TPD. Satu tema didedikasikan untuk mendiskusikan dua kasus unik. Secara keseluruhan, dengan merefleksikan peristiwa kritis, semua partisipan mampu memahami pengalaman mereka secara lebih mendalam dan oleh karenanya, membuat pengalaman tersebut bermakna. Maka dari itu, penelitian ini menganjurkan agar penggunaan refleksi dengan kerangka CIT diinvestigasi lebih lanjut dalam skala yang lebih besar dengan lebih banyak partisipan dan frekuensi refleksi yang dilakukan.
