Abstract
Gonzalez, AM, Accetta, MR, Spitz, RW, Mangine, GT, Ghigiarelli, JJ, and Sell, KM. Red spinach extract supplementation improves cycle time trial performance in recreationally active men and women. J Strength Cond Res 35(9): 2541–2545, 2021—To examine the effects of short-term red spinach extract (RSE) supplementation on cycling time trial performance, 17 recreationally active men (n = 9, 22.2 ± 3.8 years) and women (n = 8, 22.8 ± 3.5 years) underwent 2 testing sessions administered in a randomized, counterbalanced, double-blind fashion. Subjects were assigned to supplement daily with 1 g of RSE or placebo (PL) for 7 days priorly and 1 hour before completing a 4-km cycling time trial test. Performance variables (time-to-completion, average power, relative power, cadence, and average speed), subjective measures (perceived exertion and muscle fatigue), heart rate, and blood pressure were assessed during each testing session. Compared to PL, RSE supplementation significantly lowers (p = 0.017,

= 0.24) post-exercise diastolic blood pressure (66.1 ± 6.1 vs. 70.1 ± 5.0 mm Hg). Red spinach extract supplementation also significantly improved (p ≤ 0.022,

= 0.30–0.37) 4-km completion time (404.6 ± 24.6 vs. 410.6 ± 31.3 seconds), average power (185.9 ± 32.2 vs. 181.6 ± 35.1 W), relative power (2.53 ± 0.44 vs. 2.46 ± 0.40 W·kg−1), and average speed (35.7 ± 2.2 vs. 35.3 ± 2.5 km·h−1). In addition, significant trial × sex interactions (p ≤ 0.022,

= 0.30–0.36) were observed for these performance measures, whereby only women showed significant improvement during RSE compared with PL trials. In conclusion, RSE supplementation significantly reduced time-to-completion, increased measures of power and speed, and lowered post-exercise diastolic blood pressure during a 4-km cycling time trial without altering subjects' perceived exertion or subjective measures of muscle fatigue. Finally, it is possible that women may be more responsive in regard to increasing performance after supplementation.

Abstract
Boehringer, S and Whyte, DG. Validity and test-retest reliability of the 1080 Quantum System for bench press exercise. J Strength Cond Res 33(12): 3242–3251, 2019—This study assessed the validity and reliability of the 1080 Quantum (1080Q) during the bench press exercise. Twenty-seven resistance-trained men (28 ± 4 years; body mass 88.9 ± 12.8 kg; 1 repetition maximum [1RM] bench press 94.8 ± 10.7 kg) completed 2 test-retest sessions, separated by 1 week. In each session, subjects performed single repetitions at 30, 40, 50, 60, 70, and 80% of their bench press 1RM. Mean velocity (Vmean), peak velocity (Vpeak), mean force (F
mean), peak force (F
peak), mean power (Pmean), and peak power (Ppeak) were simultaneously assessed using the 1080Q Synchro and a linear position transducer (GymAware; Kinetic Performance Technology, Canberra, Australia). The overall performance of the 1080Q was both valid (r = 0.94–1.00) and reliable (coefficient of variation [CV] = 1.7–8.0%, intraclass correlation coefficient [ICC] = 0.90–1.00) for all measures, although both fixed and systematic biases were present. When assessed at each of the relative loads, the 1080Q remained valid for all measures apart from F
mean at 30% 1RM (r = 0.78) and F
peak at 70 (r = 0.81) and 80% (r = 0.57) 1RM. The 1080Q also demonstrated excellent reliability at all relative loads apart from the heaviest, where Vmean (CV = 11.0%, ICC = 0.69), Pmean (CV = 11.4%, ICC = 0.65), and Ppeak (CV = 10.2%, ICC = 0.79) reliability was reduced. These data indicate that athletes and strength and conditioning coaches can confidently use the 1080Q to monitor training progression; however, caution should be taken when assessing performance measures at the either end of the load spectrum.

Abstract
Choi, JH, Kim, DE, and Cynn, HS. Comparison of trunk muscle activity between traditional plank exercise and plank exercise with isometric contraction of ankle muscles in subjects with chronic low back pain. J Strength Cond Res 35(9): 2407–2413, 2021—This study aimed to compare the effects of 4 different ankle conditions on the activities of rectus abdominis (RA), external oblique (EO), transversus abdominis/internal oblique (TrA/IO), and erector spinae (ES) muscles during plank exercise in subjects with chronic low back pain (CLBP). Twenty-two subjects with CLBP participated in this study. The subjects performed the traditional plank and plank with 3 different ankle muscle contraction types (isometric contraction of ankle dorsiflexor, plantarflexor, and without ankle muscle contraction). Surface electromyography was used to measure the activities of RA, EO, TrA/IO, ES, tibialis anterior, and gastrocnemius muscles. A 1-way repeated-measures analysis of variance was used to assess the statistical significance of activities of the RA, EO, TrA/IO, and ES muscles. The activities of RA, EO, and TrA/IO muscles were significantly greater in the plank with isometric contraction of ankle dorsiflexor (PlankDF) than in the other 3 plank exercises. No significant difference in the activity of ES muscles was revealed during the 4 plank exercises. The activities of all abdominal muscles during PlankDF were significantly higher than those during the traditional plank, as well as during the plank with isometric contraction of ankle plantarflexor (PlankPF) and the plank without ankle muscular contraction (Plankw/o), and more than 60% of maximal voluntary isometric contraction was observed. Thus, PlankDF could be applied not only as a rehabilitation strategy for patients with decreased core stability owing to weakness of abdominal muscles but also as fitness program for improving core strength.

Abstract
Fariñas, J, Mayo, X, Giraldez-García, MA, Carballeira, E, Fernandez-Del-Olmo, M, Rial-Vazquez, J, Kingsley, JD, and Iglesias-Soler, E. Set configuration in strength training programs modulates the cross education phenomenon. J Strength Cond Res 35(9): 2414–2420, 2021—This study aimed to compare the strength gains in the nontrained arm after 2 independent unilateral training programs differing in the set configuration. Thirty-five subjects were randomly assigned to 3 groups: traditional training (TT; n = 12), cluster training (CT; n = 11), or control (CON; n = 12). The experimental groups performed a 5-week training program of a unilateral biceps curl exercise with the dominant limb using the 10 repetition maximum (10RM) load. Traditional training performed 5 sets of 6 repetitions and 135 seconds of rest between sets. Cluster training completed 30 repetitions with 18.5 seconds of rest between each repetition. Anthropometry (ANT), muscle thickness (MT), 1RM, the number of repetitions with 10RM (n10RM), and isometric maximal voluntary contraction (MVC) were measured before and after the intervention. Regarding the nontrained arm, TT improved 1RM (7.3%, p < 0.001). No changes were observed in CT. Regarding the trained arm, TT improved 1RM (9.1%, p < 0.001), n10RM (p = 0.005), and MVC (p = 0.011), whereas CT only showed a trend for improvement of 1RM (3.4%, p = 0.052). These results suggest that when total volume and repetition-to-rest ratio are equated, a more fatiguing set configuration causes a higher effect on the non-trained limb.

Abstract
Ouergui, I, Benyoussef, A, Houcine, N, Abedelmalek, S, Franchini, E, Gmada, N, Bouhlel, E, and Bouassida, A. Physiological responses and time-motion analysis of kickboxing: differences between full contact, light contact, and point fighting contests. J Strength Cond Res 35(9): 2558–2563, 2021—This study investigated the physiological responses and time structure of kickboxing styles (full contact, light contact, and point fighting). Blood lactate [La] before and after combats, mean heart rate (HRmean), percentage of time spent in HR zones, and rating of perceived exertion were assessed. Time spent in high-intensity activities (HIAs), low-intensity activities (LIAs), and referee pauses (P) were recorded according to rounds (R) and kickboxing styles. [La] increased statistically significant after kickboxing combats (p < 0.001) and was higher after light contact compared with point fighting (p = 0.029). HRmean did not differ between kickboxing specialties (p = 0.200). However, more time was spent on HR zones 4 and 5 (Z4: 80–90% and Z5: 90–100% HRmax) than in other zones (all p < 0.001). Rating of perceived exertion scores were higher after light and full contact combats compared with point fighting (p = 0.007 and 0.093, respectively). High-intensity activities, LIAs, and pauses did not statistically differ across rounds (p > 0.05). Moreover, HIA values were lower than LIA (all p < 0.001), and HIA and LIA were higher than pause for all rounds and styles (all p < 0.001). Full contact elicited higher HIA compared with point fighting (p = 0.003, 0.001, and 0.002 for round 1, 2, and 3, respectively). Coaches and strength and conditioning professionals should emphasize anaerobic and muscle power development for all disciplines, especially for full and light contact and maximal aerobic power enhancement by targeting specific HR zones. Moreover, training regimen may include high-intensity interval training to mimic these sports' specificity using the effort-pause ratios according to different kickboxing sports.

Abstract
_____________________________________________________________
At present there are many teaching techniques derived from games which are then applied in the field of teaching, one of which is the Scrambel technique. Through this game the students compete to compile the vocabulary of the letters that have been randomized. This study uses a type of quasi-experimental research. The research design used in this study was "One Groups Pretest-Posttest Design", namely the design of the study that had a pretest before being treated and posttest after being treated. But after using the Scrambel technique in the experimental class, the post test results were different. Based on the results of t-paired calculations obtained data results from t arithmetic = 0.002. Whereas for sig. t paired for N = 13 and degrees of freedom (db) N-1 = 12 is 0.05. That means that the results of t count are smaller than sig. t paired. Based on the results of these data, it can be concluded that the Scrambel technique is proven to improve mastery of Japanese vocabulary in 5th semester students of BSI Akpar Bandung. From these results it can be seen that the Scrambel technique can improve mastery of Japanese vocabulary so that it can be used as an alternative to vocabulary learning.

INTRODUCTION: The use of a cycle ergometer for the upper limbs may contribute to maintain the functional capacity in patients after heart surgery (HS). OBJECTIVES: To investigate the cardiorespiratory responses of HS patients receiving or not vasoactive drugs (VADs) during the realizations of cycle ergometer for upper limbs, verifying the incidence of loss of radial arterial catheter or of steel wire fractures in the sternum. MATERIAL AND METHODS: A pilot study involving 26 patients divided in 2 groups. Group CO: no use of VADs (13 patients, age: 57±12 years, 09 male) and VAD group: (13 patients, age: 61±10 years, 07 male), submitted to HS, which on the first postoperative day (1stPO) performed the cycle ergometer for upper limbs. The parameters evaluated during the exercise were heart rate (HR), oxygen saturation (SpO2), dyspnea, fatigue of upper limbs and mean arterial pressure (MAP). The incidence of losses of the radial artery catheter and of steel wire fractures in the sternum was calculated. Statistical analysis adopted one-way or two-way analysis of variance, with post hoc from Newman Kauls or Scheffé, when necessary. The significance level was 0.05%. RESULTS: HR increased in both groups at the end of the exercise (p=0.00), with no difference between them (p=0.97); SpO2, dyspnea and MAP did not change from rest to the end of exercise (p=0.49; p=0.78 and p=0.25, respectively); The fatigue in the upper limbs increased in both groups (p=0.04), without difference between groups (p=0.79); There was no event of loss of radial artery catheter or steel wire fractures in the sternum. CONCLUSION: The adoption of the cycle ergometer for upper limbs was safe in the 1stPO of HS, even in the individuals using VADs. There was no relationship between the use of the upper limbs cycle ergometer and losses of arterial catheters or steel wire fractures in the sternum.

Tanggungjawab sosial perusahaan atau disebut Corporate Social Responsibility (CSR) merupakan strategi perusahaan dalam mengakomodasi kebutuhan dan kepentingan stakeholdernya. Pelaksanaan CSR membutuhkan dukungan pemerintah daerah, kepastian hukum, dan jaminan ketertiban sosial. Salah satu dampak dari pendirian perusahaan oleh pemilik modal yang tergabung dalam sebuah corporation adalah muncul kesenjangan antara pihak perusahaan (corporate) dengan masyarakat setempat yang dapat mempengaruhi kestabilan negara. Suatu perusahaan sebagai organisasi sosial perlu berinteraksi dengan lingkungan sosialnya. Oleh karena itu instansi perlu memberikan perhatian kepada lingkungannya terhadap dampak yang ditimbulkan dari kegiatan operasional instansi dengan menjalankan program CSR. Perbankan dalam hal ini memiliki banyak hubungan secara langsung dengan masyarakat dalam bidang peningkatan ekonomi. Oleh karena itu sebagai bentuk tanggungjawab sosial kepada masyarakat, beberapa perbankan menyalurkan program program bina lingkungan tersebut terdiri atas pembangunan sarana umum, bantuan bencana alam, sarana pendidikan, kesehatan dan ibadah, serta pelestarian lingkungan.
