Abstract
Glassbrook, DJ, Brown, SR, Helms, ER, Duncan, S, and Storey, AG. The high-bar and low-bar back-squats: a biomechanical analysis. J Strength Cond Res 33(7S): S1–S18, 2019—No previous study has compared the joint angle and ground reaction force (vertical force [Fv]) differences between the high-bar back-squat (HBBS) and low-bar back-squat (LBBS) above 90% 1 repetition maximum (1RM). Six male powerlifters (POW) (height: 179.2 ± 7.8 cm; mass: 87.1 ± 8.0 kg; age: 21–33 years) of international level, 6 male Olympic weightlifters (OLY) (height: 176.7 ± 7.7 cm; mass: 83.1 ± 13 kg; age: 22–30 years) of national level, and 6 recreationally trained male athletes (height: 181.9 ± 8.7 cm; mass: 87.9 ± 15.3 kg; age: 23–33 years) performed the LBBS, HBBS, and both LBBS and HBBS (respectively) up to and including 100% 1RM. Small to moderate (d = 0.2–0.5) effect size differences were observed between the POW and OLY in joint angles and Fv, although none were statistically significant. However, significant joint angle results were observed between the experienced POW/OLY and the recreationally trained group. Our findings suggest that practitioners seeking to place emphasis on the stronger hip musculature should consider the LBBS. Also, when the goal is to lift the greatest load possible, the LBBS may be preferable. Conversely, the HBBS is more suited to replicate movements that exhibit a more upright torso position, such as the snatch and clean, or to place more emphasis on the associated musculature of the knee joint.

Abstract
Chan, APC, Yang, Y, Wong, FKW, Yam, MCH, Wong, DP, and Song, W-F. Reduction of physiological strain under a hot and humid environment by a hybrid cooling vest. J Strength Cond Res 33(5): 1429–1436, 2019—Cooling treatment is regarded as one of good practices to provide safe training conditions to athletic trainers in the hot environment. The present study aimed to investigate whether wearing a commercial lightweight and portable hybrid cooling vest that combines air ventilation fans with frozen gel packs was an effective means to reduce participants' body heat strain. In this within-subject repeated measures study, 10 male volunteers participated in 2 heat-stress trials (one with the cooling vest—COOL condition, and another without—CON condition, in a randomized order) inside a climatic chamber with a controlled ambient temperature 33° C and relative humidity (RH) 75% on an experimental day. Each trial included a progressively incremental running test, followed by a 40-minute postexercise recovery. Core temperature (Tc), heart rate (HR), sweat rate (SR), rating of perceived exertion (RPE), exercise duration, running distance, and power output were measured. When comparing the 2 conditions, a nonstatistically significant moderate cooling effect in rate of increase in Tc (0.03 ± 0.02° C·min−1 for COOL vs. 0.04 ± 0.02° C·min−1 for CON, p = 0.054, d = 0.57), HR (3 ± 1 b·min–1·min−1 for COOL vs. 4 ± 1 b·min–1·min−1 for CON, p = 0.229, d = 0.40), and physiological strain index (PSI) (0.20 ± 0.06 unit·min−1 for COOL vs. 0.23 ± 0.06 unit·min−1 for CON, p = 0.072, d = 0.50) was found in the COOL condition during exercise. A nonstatistically significant (p > 0.05) trivial cooling effect (d < 0.2) was observed between the COOL and CON conditions for measures of exercise duration, running distance, power output, SR, and RPE. It is concluded that the use of the hybrid cooling vest achieved a moderate cooling effect in lowering the rate of increase in physiological strain without impeding the performance of progressively incremental exercise in the heat.

Abstract
Miranda, H, Maia, MF, Paz, GA, de Souza, JAAA, Simão, R, Farias, DA, and Willardson, JM. Repetition performance and blood lactate responses adopting different recovery periods between training sessions in trained men. J Strength Cond Res 32(12): 3340–3347, 2018—The purpose of this study was to examine the effect of different recovery periods (24, 48, and 72 hours) between repeated resistance training (RT) sessions for the upper-body muscles on repetition performance and blood lactate responses in trained men. Sixteen recreationally trained men (age: 26.1 ± 3.1 years; height: 179 ± 4.5 cm; body mass: 82.6 ± 4.0 kg, 4.5 ± 2.2 years of RT experience) participated in this study. Eight repetition maximum (8RM) loads were determined for the bench press (BP), 30° incline bench press (BP30), and 45° incline bench press (BP45) exercises. To assess the effects of different recovery periods between repeated training sessions, 3 protocols were performed in randomized order, including 24 hours (P24), 48 hours (P48), and 72 hours (P72). Each RT session consisted of performing 4 repetition maximum sets of the BP, BP30, and BP45 with 8RM loads and 2-minute rest intervals between sets. Blood lactate levels were measured presession (PRE), immediately postsession (POST), 3 minutes postsession (P3), and 5 minutes postsession (P5). For the P24 protocol, significant decreases in repetition performance were found between sessions for the BP, BP30, and BP45 exercises, respectively. When considering session 2 only, the total work (repetition × sets) was significantly higher under P48 and P72 compared with P24 for the BP30 and BP45 exercises. Blood lactate levels (i.e., POST, P3, and P5) significantly increased for session 2 under the P24 compared with the P48 and P72 protocols, respectively. Therefore, coaches and practitioners who need to accomplish a higher training volume for the upper-body muscles should adopt recovery periods longer than 24 hours between sessions that train the same or similar muscle groups.

Abstract
Cummings, PM, Waldman, HS, Krings, BM, Smith, JW, and McAllister, MJ. Effects of fat grip training on muscular strength and driving performance in division I male golfers. J Strength Cond Res 32(1): 205–210, 2018—Fat grip (FG) training is implemented into strength and conditioning programs with the overall goal of increasing grip strength. Previous research assessing the effect of training with increased grip diameters compared with standard Olympic bar diameters has mainly been in acute settings. Therefore, the purpose of this study was to examine to effects FG training compared with normal diameter grip (CON) training during an 8-week periodized resistance training (RT) program in division I male golfers. Subjects (n = 10) were randomly assigned into 2 groups: the FG group (n = 5, scoring average: 75.4 ± 2.0) and CON group (n = 5, scoring average: 75.0 ± 0.5). Both groups participated in 8 weeks of RT (3 d·wk−1). The FG group completed every lift and repetition using FG, compared with the CON training group which used normal diameter bars. Pretraining and posttraining performance variables included swing speed, ball speed, driving distance, driving carry, maximum pull-ups to failure, right and left hand grip strength, and 1 repetition max trap-bar deadlift. The FG group demonstrated significant increases (p ≤ 0.05) in ball speed, carry, drive distance, and left hand grip strength after 8 weeks of RT. In a population, such as low-handicap division I male golfers, FG training may allow for athletes to increase golf-specific performance after 8 weeks of periodized RT. Strength and conditioning coaches may use FG training over the course of a training program with athletes who require adequate grip strength to further elicit training adaptations.

ObjectiveDiffuse sclerosing variant papillary thyroid carcinoma (DSVPTC) is an uncommon variant of papillary thyroid carcinoma (PTC). The biological behaviors and prognostic outcomes of this variant, however, are still controversial. The aim of this systematic review and meta-analysis is to investigate the prognostic significance and outcomes of DSVPTCs in comparison with classical PTCs (cPTCs).MethodsAn electronic search was performed in five libraries: PubMed, Scopus, ISI, World Health Organization Global Health Library (WHO GHL) and Virtual Health Library (VHL) in June 2016. Published data were extracted and were pooled into odds ratios (OR), mean differences and corresponding 95% confidence intervals (CI) using random-effect model. Publication bias was analyzed using Egger’s regression test and funnel plot observation.ResultsFrom 315 articles, we included 16 articles comprising 732 DSVPTCs for meta-analysis. Overall, DSVPTC manifested more aggressive clinicopathological behaviors than cPTC such as higher rate of vascular invasion (OR: 5.33; 95% CI: 3.08–9.23), extrathyroidal extension (OR: 2.96; 95% CI: 2.04–4.30), lymph node metastasis (OR: 5.40; 95% CI: 2.82–10.35), distant metastasis (OR: 3.61; 95% CI: 1.89–6.88) and were more likely to relapse (OR: 2.83; 95% CI: 1.59–5.05). DSVPTC patients were associated with a worsened overall survival (HR: 1.89; 95% CI: 1.36–2.62).ConclusionDSVPTCs should be considered high-risk PTCs because of high propensity for tumor invasion, metastasis, relapse and mortality. Aggressiveness of DSVPTCs might be related to a different molecular pathway than that in cPTCs.

Penggunaan intensitas cahaya pada unit penangkapan light fishing cenderung meningkat. Hal ini, didasari atas persepsi bahwa intensitas cahaya yang tinggi akan meningkatkan hasil tangkapan. Fenomena ini dijadikan suatu penelitian yang dilakukan selama 3 minggu pada bulan September 2004 di perairan Pemalang Jawa Tengah. Alat tangkap pukat cincin mini (mini purse seine) di pantai utara Jawa pada operasi penangkapan selain menggunakan rumpon juga mengggunakan cahaya sebagai alat bantu penangkapan. Pengukuran nilai intensitas lampu dilakukan dengan meggunakan LI COR 250 quantum meter (μmol sÉ¹ mÉ²) pada jumlah lampu yang berbeda, dan digunakan pula akustik EY 500 untuk memperoleh data sebaran dan gerombolan ikan yang berada dalam pengaruh cahaya lampu. Pada deteksi awal (A) ikan cenderung mengelompok pada lahan intensitas tinggi, deteksi ke 2 (B) pengelompokkan mulai terkonsentrasi dekat kapal, deteksi ke-3 (C) pengelompokkan ikan bertambah banyak, dan deteksi ke-4 (D) kelompok ikan berada pada lahan yang sangat memungkinkan untuk ditangkap. Dari hasil penelitian diperoleh laju tangkap (catch rate) 125,7 kg per tawur. Perbedaan jumlah lampu yang sedikit tidak menunjukkan pengaruh yang terlalu besar terhadap hasil tangkapan. The influence of light intensity to the light fishing practices commonly tends to increase. Fishermen believe that with the higher intensity of light the bigger catch they have. This phenomenon stimulated us to a research that during was done three weeks on September 2004 in Pemalang West Java. Mini purse seine is conduct at north coast of Java use payaos and light artificial for fish attractive. LI COR 250 quantum metre (μmol sÉ¹ mÉ²) was used for light intencity at different lamps amount and EY 500 acoustic to obtain the data of fish school in influence of lamp light. At the first detecting (A) fish school was concentrated in high intensity area, the second detecting (B) the concentration was closer to the ship, the third detecting (C) fish school increased, and the forth detecting (D) fish school was consentrated in catchable area. The results show that the cath rate was 125.7 kg per setting. The difference of lamps amount with a small intensity did not show significant influence to the catch haul.

Aim. Development of a model of hindlimb ischemia in rats to assess the effectiveness of gene and cell therapy.
Methods. In the first stage of this approach the external iliac artery was ligated immediately after bifurcation of the common iliac artery. Then the femoral artery was ligated before its branching into the descending genicular, popliteal and saphenous arteries with following dissection of arteries between ligatures. The second stage of this approach was performed seven days after the completion of the first stage: branches of popliteal artery to gastrocnemius muscle and formed collaterals were ligated and dissected. Hindlimb blood flow was assessed by laser Doppler flowmetry. Animals were euthanazied 14, 17, 21, 28, 35, 42 days after the first stage. The paraffin sections of gastrocnemius muscles were stained with Mallory trichrome and with antibodies to CD34.
Results. Histopathological analysis showed a continuous hindlimb ischemia of operated limb without any native skeletal muscle structure restoration and with significant interstitial fibrosis (11.895.53% vs 2.552.13% in intact limb by day 42, p 0.05). Polymorphic muscle fibers in operated limb with significantly smaller diameter and reduced capillary density (0.820.03 vs 1.910.06 in intact limb by day 42, p 0.05) were revealed. Laser Doppler flowmetry revealed reduction of blood flow in the operated limb (0.670.22 of intact limb blood flow by day 42).
Conclusion. Our developed two-stage model of hindlimb ischemia in rats leads to histologic changes characteristic for the same pathology in human.

Background: Clinical outcomes from videoscope assisted minimally invasive surgery (VMIS) at 36 to 58 months are reported.Methods: Fourteen patients having sites with residual probing depth (PD) of at least 5 mm and 2 mm loss of clinical attachment level (CAL) after initial non‐surgical therapy were treated with VMIS.Results: At 36 months or greater post‐surgery there was a statistically significant improvement (P <0.001) in mean PD and CAL (PD: 3.80 ± 1.18 mm, CAL: 4.16 ± 1.18 mm) in all surgical sites compared with baseline. There was a mean improvement in soft tissue height (0.36 ± 0.64 mm, P = 0.03). In most cases, patients reported no postoperative discomfort.Conclusions: Improvements from VMIS appear to be favorable when compared with previously reported results of periodontal regenerative surgery. All improvements were stable over time. The lack of post‐surgical recession after VMIS has not been reported with traditional regenerative surgery.

Published: February 2017

ABSTRACT The growth rate between male and female red tilapia Oreochromis sp. is different. Generally, the male red tilapia grows faster than the female. Furthermore, the maturation process of red tilapia is relatively fast which causes slower growth rate. One of solutions to this problem is by rearing all male population or mono-sex culture. The method used in this study was commercial feed enrichment with 17α-methyltestosterone at different dosages and water temperature manipulation. The purpose of this research was to examine the effects of commercial feed enrichment with different dosages of 17α-methyltestosterone and water temperature manipulation on success rate of sex reversal of red tilapia into all male population. This research consisted of different temperature treatments (with and without water heating) and 17α- methyltestosterone dosages (0, 10, 20 mg/kg of commercial feed). The best dosage of 17α-methyltestosterone was 20 mg/kg of commercial feed with male to female sex ratio of 86.31%, daily growth rate of 8.18%, and feed conversion ratio of 1.53. In this study, the best treatment to produce the male seeds was the 17α-methyltestosterone treatment. Keywords: 17α-methyltestosterone, sex reversal, red tilapia, temperature ABSTRAK Ikan nila merah Oreochromis sp. memiliki laju pertumbuhan yang berbeda antara ikan jantan dan betina. Umumnya ikan nila merah jantan lebih cepat tumbuh dibandingkan betinanya. Selain itu, ikan nila memiliki sifat cepat matang gonad dan mudah memijah sehingga akan menghambat pertumbuhan ikan. Salah satu cara untuk mengurangi masalah yang terjadi yakni dengan memelihara populasi ikan nila merah tunggal kelamin atau monoseks jantan. Metode yang dilakukan adalah pemberian hormon 17α-metiltestosteron dengan dosis berbeda melalui pakan buatan dan peningkatan suhu air. Penelitian ini bertujuan untuk mengetahui pengaruh dosis hormon 17α-metiltestosteron melalui pakan buatan dan peningkatan suhu air terhadap keberhasilan alih kelamin jantan pada ikan nila merah. Penelitian ini terdiri atas perlakuan suhu (dengan dan tanpa pemanasan air) dan dosis 17α-metiltestosteron (0, 10, 20 mg/kg pakan). Dosis hormon 17α-metiltestosteron terbaik yang didapatkan adalah 20 mg/kg pakan dengan nisbah kelamin jantan 86,31%, laju pertumbuhan harian 8,18%, dan rasio konversi pakan 1,53.
