Published: May 2018

Background and Purpose:
Exercise programs for people with dementia need to be optimized. We therefore evaluated the applicability of a high-intensity functional exercise program among people with dementia in nursing homes with regard to attendance, achieved exercise intensity, adverse events, a focus on dementia type, and whether symptoms of dementia or other medical conditions common in this population were associated with program applicability.

Methods:
The Umeå Dementia and Exercise study, a cluster-randomized controlled trial set in 16 nursing homes in Umeå, Sweden. Ninety-three people with dementia (mean [SD] Mini-Mental State Examination score of 15.4 [3.4]) were randomized to the exercise intervention. Thirty-four participants had Alzheimer's disease (AD) and 59 non-Alzheimer's dementia (non-AD). High-Intensity Functional Exercise (HIFE) program was conducted in groups of 3 to 8 participants. Two physiotherapists led 5 sessions (45 minutes each) per fortnight for 4 months (total 40 sessions).

Results:
Median attendance rate was 82.5%. Lower limb strength exercises were performed at high or medium intensity at a median interquartile range of 94.7% (77.8%-100%) of attended sessions. Participants with non-AD performed more sessions with high intensity in strength exercises than participants with AD (median interquartile range, 53.8% [25.7%-80%] vs 34.9% [2.02%-62.9%]; P = .035). Balance exercises were performed at high intensity at a median interquartile range of 75% (33.3%-88.6%). Adverse events (all minor and temporary, mostly musculoskeletal) occurred during the exercise sessions in 16% of attended sessions. Low motivation was the most common barrier for attendance. Buildup period, low motivation, and pain were common barriers for achieving high intensity in balance and strength exercises, and fear was a barrier in balance exercises. Of medical conditions, only behavioral and psychological symptoms of dementia, including apathy, were negatively associated with applicability.

Conclusion:
A group-based, supervised, and individualized high-intensity functional exercise program seems to be applicable with regard to attendance, achieved intensity, and adverse events during the exercise sessions, in people with mild to moderate dementia in nursing homes. Effective strategies to enhance motivation to participate in exercise, as well as prevention and treatment of pain and behavioral and psychological symptoms of dementia, are important when promoting exercise participation in this population.

Abstract
Chen, WH, Wu, HJ, Lo, SL, Chen, H, Yang, WW, Huang, CF, and Liu, C. Eight-week battle rope training improves multiple physical fitness dimensions and shooting accuracy in collegiate basketball players. J Strength Cond Res 32(10): 2715–2724, 2018—Basketball players must possess optimally developed physical fitness in multiple dimensions and shooting accuracy. This study investigated whether battle rope (BR) training enhances multiple physical fitness dimensions, including aerobic capacity (AC), upper-body anaerobic power (AnP), upper-body and lower-body power, agility, and core muscle endurance, and shooting accuracy in basketball players and compared its effects with those of regular training (shuttle run [SR]). Thirty male collegiate basketball players were randomly assigned to the BR or SR groups (n = 15 per group). Both groups received 8-week interval training for 3 sessions per week; the protocol consisted of the same number of sets, exercise time, and rest interval time. The BR group exhibited significant improvements in AC (Progressive Aerobic Cardiovascular Endurance Run laps: 17.6%), upper-body AnP (mean power: 7.3%), upper-body power (basketball chest pass speed: 4.8%), lower-body power (jump height: 2.6%), core muscle endurance (flexion: 37.0%, extension: 22.8%, and right side bridge: 23.0%), and shooting accuracy (free throw: 14.0% and dynamic shooting: 36.2%). However, the SR group exhibited improvements in only AC (12.0%) and upper-body power (3.8%) (p < 0.05). The BR group demonstrated larger pre–post improvements in upper-body AnP (fatigue index) and dynamic shooting accuracy than the SR group did (p < 0.05). The BR group showed higher post-training performance in upper-body AnP (mean power and fatigue index) than the SR group did (p < 0.05). Thus, BR training effectively improves multiple physical fitness dimensions and shooting accuracy in collegiate basketball players.

AbstractKeiner, M, Rähse, H, Wirth, K, Hartmann, H, Fries, K, and Haff, GG. Influence of maximal strength on in-water and dry-land performance in young water polo players.J Strength Cond Res34(7): 1999–2005, 2020—Water polo is a multifaceted sport that is characterized by explosive actions, including sprint swimming, jumping, throwing, and struggling against opponents. Based on these factors, maximal and speed strength may be important characteristics to develop in-water polo players. However, more research is needed to further understand the relationship between various strength characteristics and water polo performance. Therefore, the primary purpose of this study was to examine the relationships between strength, speed strength, and markers of water polo performance in youth water polo players. Sixty-one male youth water polo players (10–14 years, 11.9 ± 1.3 years) had their 1-repetition maximum (1RM) bench press and squat, dry-land speed-strength performance (squat jump [SJ], countermovement jump [CMJ], and medicine ball throw), in-water performance (sprint swim and water jump), and anthropometric measurements assessed. Fifty to 60% of the variance in sprint performance was explained by the 1RM bench press and arm span. The influence of the bench press 1RM was more than twice that of the anthropometric factors. Maximum strength in the squat and speed-strength (jump height in SJ, CMJ) variables explained 18–25% variance in the eggbeater kick (a leg strike technique to stay above and jump out of water), and the bench press 1RM explained the 42% of the variance in loaded throws without the influence of anthropometric factors. This study suggests that upper- and lower-body maximal strength parameters are important predictors of the performance capacity of water polo players.

Abstract
Garcia-Hermoso, A, Cofre-Bolados, C, Andrade-Schnettler, R, Ceballos-Ceballos, R, Fernández-Vergara, O, Vegas-Heredia, ED, Ramírez-Vélez, R, and Izquierdo, M. Normative reference values for handgrip strength in Chilean children at 8–12 years old using the empirical distribution and the lambda, mu, and sigma statistical methods. J Strength Cond Res 35(1): 260–266, 2021—The aim of this study was 2-fold (a) to provide sex- and age-specific handgrip reference standards for Chilean children aged 8–12 years and (b) to compare the levels of handgrip strength of Chilean children with those of children from other countries. This cross-sectional study enrolled 2,026 schoolchildren (boys n = 1,334 and girls n = 692, mean age 10.18 [1.16] years old). Handgrip strength was measured using a hand dynamometer with an adjustable grip. Relative handgrip strength was calculated by dividing handgrip strength by body mass (handgrip strength kg per mass kg). Smoothed centile curves and tables for the 10th, 20th, 30th, 40th, 50th, 60th, 70th, 80th, and 90th centiles were calculated using Cole's lambda, mu, and sigma method. The results indicate that mean handgrip strength was greater among boys than girls. Handgrip strength peaked at 16.25 (5.03) kg in boys and 14.90 (4.32) kg in girls. In addition, relative handgrip strength peaked at 0.38 (0.08) in boys and 0.34 (0.07) in girls. Chilean children of both sexes scored higher than their South American counterparts from Colombia and Peru but showed lower handgrip strength than European and Australian children. Our results provide, for the first time, sex- and age-specific handgrip reference standards for Chilean children aged 8–12.9 years. These normative reference values could help identify the levels of handgrip strength that need attention to provide appropriate feedback and advice to children about how to best improve their overall physical fitness.

Abstract
Andre, TL, Gann, JJ, Hwang, PS, Ziperman, E, Magnussen, MJ, and Willoughby, DS. Restrictive breathing mask reduces repetitions to failure during a session of lower-body resistance exercise. J Strength Cond Res 32(8): 2103–2108, 2018—The purpose of this study was to determine the effect of restrictive breathing mask (RBM) on muscle performance, hemodynamic, and perceived stress variables during a session of lower-body resistance exercise. In a crossover design, 10 participants performed 2 separate testing sessions, RBM and no mask, consisting of squat, leg press, and leg extension. The paired-samples t-test was used for session rating of perceived exertion (S-RPE), perceived stress before and after, heart rate (HR), pulse oximetry, and a 2 × 4 (session [mask, no mask] × time [squat exercise, leg press exercise, leg extension exercise, total resistance exercise session]) factorial analysis of variance with repeated measures (p ≤ 0.05). A significant decrease was found in total repetitions during the RBM condition (p < 0.01). A majority of the decrease in repetitions to failure occurred in the squat (p < 0.05) and in the leg press (p < 0.01), whereas no difference was observed in leg extension (p = 0.214). A significant increase was observed in S-RPE during the RBM session (p < 0.01). A significant increase was found in prestress (p < 0.01) and poststress (p = 0.01) in the RBM session. No significant difference existed for HR between exercise sessions (p = 0.08). A significant decrease existed in pulse oximetry during the RBM session (p < 0.01). The use of an RBM had a negative effect on the number of repetitions completed during an acute session of lower-body resistance training.
Crack Size and Shape Considerations Related to Near-Threshold Fatigue Crack Growth Rate Behavior

Published: May 2018

Abstract
It is well recognized that crack size or load history or both have an important influence on near-threshold fatigue crack rate behavior at a low stress ratio. This investigation will compare the behavior of a radial crack, such as a surface flaw or a corner crack, to that of a linear crack to see if crack shape plays a role in physically small crack to long crack behavior. Recent research has unveiled a methodology to experimentally partition plasticity from roughness- and oxide-induced crack closure, showing that nonplasticity-induced closure mechanisms have a greater influence at low Kmax by orders of magnitude. Knowledge of this is key to understanding differences between long crack and physically small crack behavior in the near-threshold regime. In this study, the well behaved 2024-T351 aluminum alloy was used to generate threshold data using numerous specimen geometries, flaw geometries, crack sizes, and test procedures to highlight not only the significance of crack size but also the role of crack shape. It will be shown both experimentally and analytically that a radial crack (surface flaw, corner crack) has significantly less remote closure and, therefore, a lower threshold than a through crack (compact tension, middle crack tension), even if the crack size is the same.
Determining the Water Holding Capacity of Synthetic Track Materials for Thoroughbred Horse Racing

Published: May 2018

Abstract
Wax-coated sand, fiber, and rubber surfaces have been in use for more than a decade at a number of North American Thoroughbred racetracks. These synthetic, all-weather racing surfaces were designed to allow races on wet surfaces without impacting performance. As these tracks have aged, some have areas that no longer drain properly. A number of approaches have been taken to refresh the surfaces including re-waxing, adding fiber, and even turning over the surfaces. The results have shown mixed success, with water pooling on top of some tracks and more water retained in the depth profile on other tracks. A gravity-based water holding capacity (WHC) test has been developed to determine the amount of water retained in these surfaces. Traditional permeability measurements are also used in this study. Samples of new and six-year-old synthetic surfaces are taken from four North American Thoroughbred racetracks to examine both the drainage and water holding of the material. These surfaces were identified as having both adequate and inadequate track performances during wet weather. Control samples were also prepared with and without the wax binder. Measuring the WHC at different surface locations may help racetrack superintendents identify problem areas and quantify material changes over time. Test results generally showed that a certain amount of wax binder is necessary to minimize water holding in synthetic surfaces, but too much wax is detrimental. The amount and size of the polymer fiber and rubber constituents, as well as organic material and particulates present, also affects the WHC. Developing threshold values for an “acceptable” WHC for specific synthetic racetracks, as well as understanding primary factors that affect water holding, will allow researchers to set a performance standard to determine the timing and type of renovations that are needed to maintain safe and consistent synthetic track surfaces.

Batch technique experiment was applied to measure the elimination of 137Cs from solution using bentonite from Tasikmalaya and quartz sand from Belitung. Bentonite material was used as barrier system surrounding on a near surface disposal facility, and quartz sand as backfill material. The distribution coefficient (Kd) of 137Cs on bentonite and quartz sand samples have been measured. Contact time, variation of Na and Cs ion concentrations in solution were applied as the experiment parameters. The Kd values of 137Cs on the samples were 1700 and 3200 ml/g for bentonite and 17 and 37 ml/g for quartz sand samples, respectively. The Na and Cs concentrations in solution affected the Kd values of 137Cs on samples. Isotherm sorption result shown that the interaction of 137Cs onto solid samples was approached with Freundlich model. The data obtained from the experiments and then could be used for radionuclides migration assessment models of disposal facility in the future.DOI:http://dx.doi.org/10.15408/jkv.v4i1.7325

Diabetes Melitus (DM) adalah kelompok gangguan metabolisme yang ditandai oleh hiperglikemia akibat kerusakan pada sekresi insulin, kerja insulin atau keduanya. Penderita Diabetes Melitus Tipe 2 (DMT2) mencapai 90-95% dari keseluruhan populasi penderita diabetes tersebut. Salah satu tanaman yang potensial sebagai alternatif obat antidiabetes adalah tanaman namnam (Cynometra cauliflora). Pada penelitian ini kemampuan penyerapan glukosa oleh otot diafragma yang diisolasi dari tikus non diabetes Sprague Dawley oleh ekstrak metanol daun namnam (C. cauliflora) pada berbagai konsentrasi ditentukan. Gugus fungsi senyawa dominan pada ekstrak menggunakan FTIR (Fourier Transform Infrared). Hasilnya menunjukkan bahwa terjadinya peningkatan penyerapan glukosa oleh diafragma ketika konsentrasi ekstrak daun namnam (C. cauliflora) meningkat dan tertinggi pada konsentrasi 450 mg/mL dengan serapan 0.4254 ± 3.23 mg/mL/30 menit dengan peningkatan sebesar 373.72% dibandingkan kontrol air. Diduga kemampuan ekstrak tanaman C. Cauliflora menyerap glukosa disebabkan keberadaan golongan flavonoid. Oleh karena itu daun tanaman namnam (C. cauliflora) memiliki potensi sebagai obat antidiabetes DMT2 melalui mekanisme peningkatan penyerapan glukosa ke dalam sel.DOI:http://dx.doi.org/10.15408/jkv.v4i1.7345

Published: May 2018

Crude glycerol merupakan produk samping pembuatan biodiesel dengan kemurnian yang rendah karena masih mengandung senyawa pengotor seperti metanol, asam lemak bebas, katalis dan air. Senyawa pengotor ini harus dihilangkan supaya kualitas gliserol meningkat dan punya nilai jual yang tinggi. Adsorpsi merupakan salah satu metoda yang dapat digunakan untuk menyerap senyawa pengotor tersebut. Pada penelitian ini digunakan sekam padi sebagai adsorben karena mengandung selulosa. Selain itu sekam padi merupakan limbah, sehingga pemanfaatannya sebagai adsorben akan dapat menekan biaya proses pemurnian crude glycerol. Penelitian ini bertujuan untuk menentukan kondisi optimum proses (waktu, suhu, konsentrasi adsorben dan ukuran adsorben), kualitas gliserol yang dihasilkan dan karaktersitik adsorben sebelum dan sesudah adsorpsi (FTIR dan SEM). Crude glycerol terlebih dahulu diasamkan menggunakan asam fosfat dan selanjutnya di ekstraksi menggunakan metanol. Crude glycerol hasil ekstraksi selanjutnya di lakukan adsorpsi menggunakan sekam padi yang sudah diaktivasi. Hasil adsorpsi disaring dan ditentukan kadar gliserolnya. Hasil penelitian menunjukkan bahwa kondisi optimum adsorpsi diperoleh pada waktu 75 menit, suhu 90 oC, konsentrasi adsorben 20% dan ukuran adsorben 180 µm. Kualitas gliserol yang dihasilkan memiliki kadar gliserol 97.290%, air 1.698%, abu 0.885%, MONG 0.132%, tidak mengandung gula. Spektrum FTIR sebelum adsorpsi menunjukkan adanya gugus O-H, C=O, C=C dan C-O dan setelah adsorpsi terjadi penambahan gugus C-H alifatik. Morfologi adsorben sebelum adsorpsi memperlihatkan pori-pori yang terbuka dan setelah adsorpsi pori-pori tersebut tertutupi oleh senayawa pengotor.DOI:http://dx.doi.org/10.15408/jkv.v4i1.7498
