- Abstract
Soccer-specific training (SST) drills are used to develop physiological adaptations, technical and tactical skills, and provide coaches with greater control of external training load. Despite widespread use, there has been little analysis of SST drills. This study quantified the effect of manipulating player numbers on the physiological demands of an SST drill. Fourteen players completed nine trials (3 × 8, 10, 12 players) of a 4-min SST drill modelled on soccer time-motion data. Physiological intensity measures (heart rate, blood lactate concentration [BLa-], rating of perceived exertion [RPE]) and GPS time-motion data (movement distances and velocities) were collected for each drill. A repeated measures analysis of variance determined significant (p < 0.05) between-drill differences. Results showed variables such as total running distance (TD), mean percentage of maximum heart rate, RPE, and [BLa-] were greater for the 8-player SST drill. The 10-player drill also had a 22% greater TD and 21% higher average speed compared to the 12-player drill, which tended to have a lower activity profile. The 8-player SST drill could be used to develop aerobic capacity and repeat-sprint ability (RSA) because of a higher activity profile. The 10- and 12-player drills would be suited for RSA and sprint acceleration enhancement.

- Abstract
Introduction: Labor pain is often severe and its lack of relief can have a bad effect on the mother's physiological condition. Accurate measurement and appropriate treatment of pain is an important problem. There are several choices for the control of labor pain, however, each method has its own risks and benefits regarding its efficiency and availability; therefore, the aim of this study was to compare the rate of cesarean section and newborn Apgar in two types of physiological delivery and facilitated delivery among mothers with first delivery., Materials and Methods: This case-control study was conducted on mothers aged 18-35 who went to the hospital to give birth. In the present study, 8 sessions (90 minutes each session) were held to prepare mothers from 20 to 37 weeks of pregnancy. Candidate mothers for physiological labor were hospitalized without intervention and in the active phase of labor, and their labor stages were planned physiologically. The pain intensity of mothers was asked using a scale (VAS) during labor every half hour (according to the pain scale from 0 to 10). The average score of pain during the first and second stages, type of delivery, amount of postpartum bleeding, length of the stage of delivery, infection, and fever after delivery, Apgar score of the baby, perineal status, mother's satisfaction and the rate of hospitalization of the baby in NICU were recorded. Furthermore, the level of satisfaction with childbirth was evaluated with the help of Mackey's standard satisfaction questionnaire., Results: The average age of the physiological delivery and facilitated delivery groups was 26.37 ± 5.23 years and 26.58 ± 5.79 years, respectively. Physiological delivery significantly required less conversion to cesarean section. The most common etiology was caesarean section in the physiologic labor group, and a drop in NST was reported in the facilitated group. The analysis of the results demonstrated no significant difference between the etiology of cesarean section and the study groups. The Apgar score in the physiological group was significantly better than the facilitated group. There is no significant relationship between the study group and the amount of bleeding during delivery. Furthermore, there was no significant relationship between the study group and the incidence of postpartum infection. The rate of NICU admission in the facilitated group was found to be significantly higher than physiological delivery., Conclusion: The results of this study revealed that the rate of caesarean section, the rate of need for NICU, newborns' Apgar score, and the rate of mothers' satisfaction in physiological delivery group were significantly different from the other groups, but the rate of wound infection and the amount of postpartum bleeding in the two groups showed a significant difference.

- Abstract
Background: The primary purpose of this study was to measure the acute effects on muscle thickness, arm circumference, and peak force between unilateral seated row and unilateral biceps curl exercises for elbow flexors after a RT session in recreationally-trained subjects., Methods: Fourteen resistance-trained men (25.3±2.5years, 76.5±6.4kg, 174.6±7cm) performed 6 sets of 10RM and 2-min rest for one of two exercises (unilateral seated row exercise, USR or unilateral biceps curl, UBC). Muscle thickness (MT), arm circumference (AC), and peak force (PF) were measured before 10-min (control), pre-RT session and post-RT (immediately after, 15-min and 30-min). All acute RT variables were measured during both exercises: maximal number of repetitions (MNR), total number of repetitions (TNR), time under tension (TUT), rating of perceived exertion (RPE). Two-way ANOVAs were used to test differences between exercises and moments with an alpha of 5%., Results: For PF, there was a significant difference between pre- and post-0 for UBC and USR (P<0.001). For AC, there were significant differences between pretest × post-0-min for both exercises (P<0.001). For MT, there were significant differences between pretest × post 0-min (P<0.001), pretest × post 15-min (P<0.001) for both exercises and pretest × post 30-min only for UBC (P=0.006)., Conclusions: Both exercises induced similar increases in AC and MT for elbow flexors and reduction in peak force.

- Abstract
Objective: To compare the anesthetic effects of topical amitriptyline 2% with lidocaine 2% in isolated limb wound repair with suturing., Methods: In a randomized clinical trial, 90 patients with a complaint of isolated ulcer and require a preliminary repair by suturing were selected from patients referred to emergency department of Beast Hospital in Hamadan. First, the scars were washed and anesthetized with lidocaine 2%. If after the peak period effect of lidocaine, the pain score of patients did not decrease, they randomly assigned to two groups, Lidocaine or Amitriptyline gel. After the intervention and during the suturing, the patient's pain score was measured at the intervals specified time by the visual analogous scale (VAS) and results recorded on the checklist. Finally, the collected data were analyzed by SPSS software version 20 at 95% confidence level., Results: In the lidocaine and amitriptyline group, the mean age of the patients was 29.08 and 27.34 years, and male gender frequency was 71.1% and 80% respectively. Both groups were matched for age and sex. Mean score of pain in both groups decreased from the score of 10 before the intervention to 7.33 in the lidocaine group and 0.53 in amitriptyline group. Based on the results of the ANOVA repeated measure test, there was a statistically significant difference between the mean score of pain in the two groups ( p <0.001)., Conclusion: In patients with isolated limbs ulcers, requiring initial repair with suturing, numbness and analgesia effect of amitriptyline 2% gel, with dose 2 mg/kg is better than lidocaine 2%., Competing Interests: The authors declare no conflict of interest.

Jalilvand, F, Banoocy, NK, Rumpf, MC, and Lockie, RG. Relationship between body mass, peak power, and power-to-body mass ratio on sprint velocity and momentum in high-school football players. J Strength Cond Res 33(7): 1871-1877, 2019-The ability to rapidly shift one's body mass horizontally or vertically is common within American football irrespective of field position, and the capacity to generate power is a favorable physical quality. This requires analysis in high-school football players, especially considering the body mass disparities that exist in this population. Sixteen high-school players (7 backs and 9 linemen) completed the vertical jump (VJ) to determine jump height, peak anaerobic power measured in watts (PAPw), and power-to-body mass ratio (P:BM), and a 36.58-m sprint (0-4.57, 0-9.14, and 0-36.58-m intervals) to determine sprint velocity and momentum. Independent-samples t-tests (p < 0.05) determined differences in these variables between the backs and linemen. Pearson's correlations (r; p < 0.05) computed relationships between body mass, VJ height, PAPw, P:BM, with 36.58-m sprint velocity and momentum on the pooled data. Linemen were heavier, and slower in the 36.58-m sprint, but had greater PAPw and sprint momentum compared with backs. Body mass exhibited negative relationships to velocity across all sprint intervals (r = -0.55 to 0.70), and positive relationships with momentum across all intervals (r = 0.95-0.96). The VJ correlated with sprint velocity across all intervals (r = 0.51-0.83), but not momentum. PAPw was positively correlated with body mass and momentum across all intervals (r = 0.77-0.85), but not velocity. There were significant correlations between P:BM with velocity (r = 0.51-0.85) and momentum (r = -0.53-0.62) across all intervals. Heavier high-school players could focus on improving P:BM to positively influence jumping ability and sprint velocity.

- Abstract
Inflammatory phenomenon, including cell-free fetal DNA (cffDNA), is one of the various causes of preterm delivery. Always, there is a trend in the prediction and prevention of preterm labor. Herein, the aim of this study is to assess the value of cffDNA levels in serum of pregnant women for prediction of spontaneous preterm labor. A case-control study with nonrandomized convenience sampling was conducted. One hundred women qualifying for the study were enrolled. The participants were divided into two groups of healthy nulliparous pregnant women ( n = 50) and nulliparous pregnant women experiencing preterm labor ( n = 50). Then, venous blood was sampled from each participant and its plasma was separated and analyzed. The mean age of women in the experimental group was 22.90 years with the standard deviation of 4.04, while in the control group these two values were 23.78 and 4.37, respectively. In the experimental group, 29 patients (58%), and in the control group, 27 patients (54%) had cffDNA. The mean of the counted DNA in the experimental group was 2080/03 with the standard deviation of 909/792 while the same values for the control group were 1183/26 and 620/720, in the same order. The statistical analysis revealed that this difference was meaningful at P = 0.001. Furthermore, in the experimental group, cffDNA increased with increase in the age and the difference was meaningful. Finally, increasing pregnancy age in the experimental group led to an increase in the number of cffDNA ( P = 0.001). The results of this study indicated that the cumulative frequency of preterm labor for women with positive cffDNA was significantly higher. High levels of cells' DNA in the serum of pregnant mothers increase the risk of spontaneous preterm labor. These observations may have implications for preterm labor., Competing Interests: There are no conflicts of interest.

Lockie, RG, Moreno, MR, Lazar, A, Orjalo, AJ, Giuliano, DV, Risso, FG, Davis, DL, Crelling, JB, Lockwood, JR, and Jalilvand, F. The physical and athletic performance characteristics of Division I collegiate female soccer players by position. J Strength Cond Res 32(2): 334-343, 2018-Playing positions in soccer can exhibit different movement demands during a match, contributing to variations in physical and performance characteristics. National Collegiate Athletic Association (NCAA) soccer features different substitution rules when compared to FIFA-sanctioned matches, which could influence each players' characteristics. Therefore, this study determined the athletic performance characteristics of Division I female soccer players. Twenty-six players (3 goalkeepers; 8 defenders; 10 midfielders; 5 forwards) from the same squad completed assessments of: lower-body power (vertical and standing broad jump); linear (0-5, 0-10, 0-30 meter [m] sprint intervals) and change-of-direction (pro-agility shuttle; arrowhead change-of-direction speed test) speed; and soccer-specific fitness (Yo-Yo Intermittent Recovery Test [YYIRT] levels 1 and 2). Players were split into position groups, and a Kruskal-Wallis H test with post hoc pairwise analyses (p ≤ 0.05) calculated significant between-group differences. There were no differences in age, height, or body mass between the positions. Midfielders had a faster 0-5 m time compared with the defenders (p = 0.017) and the goalkeepers (p = 0.030). The defenders (p = 0.011) and midfielders (p = 0.013) covered a greater YYIRT2 distance compared with the goalkeepers. There were no other significant between-position differences. Overall, Division I collegiate female players from the same squad demonstrated similar characteristics as measured by soccer-specific performance tests, which could allow for flexibility in position assignments. However, a relatively homogenous squad could also indicate commonality in training prescription, particularly regarding acceleration and high-intensity running. Strength and conditioning coaches may have to consider the specific movement demands of individual positions when training these capacities.

- Abstract
The ability to complete high-intensity running is essential for soccer. The Yo-Yo Intermittent Recovery Test Level 2 (YYIRT2) can measure this capacity, but there is limited information regarding this assessment in collegiate female soccer players. This study investigated the YYIRT2 as a measure of high-intensity running in this population, and its relationship to other soccer field tests. Twenty-one players from a Division I team were recruited. In addition to the YYIRT2, subjects completed linear (0-5, 0-10, and 0-30 m sprint intervals) and change-of-direction (pro-agility and 60-yard shuttle) speed tests, as well as the YYIRT Level 1 (YYIRT1), to assess relationships with YYIRT2 by correlations (p ≤ 0.05). The correlation of YYIRT1 with the speed tests was also assessed. The YYIRT1 and YYIRT2 were standardized using z-scores for comparison with elite benchmarks to investigate relative performance on each test. The YYIRT2 and YYIRT1 distances did not significantly correlate with those of the speed tests (r = -0.251 to 0.274). There was a large relationship between YYIRT2 and YYIRT1 distances (r = 0.582), although the explained variance was low (33.87%). Mean YYIRT2 z-scores (-4.29 ± 1.66) indicated a performance further from elite benchmarks than those of the YYIRT1 (-1.92 ± 1.61), and 90.5% (19 of 21) subjects performed relatively better in the YYIRT1 than YYIRT2. The YYIRT2 provided a more specific measure of high-intensity running to that of the YYIRT1 in collegiate female soccer players. Coaches may consider using the YYIRT2 to gauge and track progress of high-intensity running capabilities and create training programs to improve this ability in female players.

- Abstract
NCAA soccer features different substitution rules compared to FIFA-sanctioned matches, with a greater availability of players who can enter the game. This could influence the physiological characteristics of the field position starters (ST) and non-starters (NST) within a collegiate women's team, which has not been previously analyzed. Thus, 22 field players from the same Division I women's soccer squad completed: vertical and standing broad jumps; 30-meter (m) sprint (0-5, 0-10, 0-30 m intervals); pro-agility and 60-yard shuttle; and the Yo-Yo Intermittent Recovery Test Level 1. Players were defined into ST (n=10) and NST (n=12) by the coaching staff. A one-way ANOVA derived any significant ( p ≤0.05) between-group differences, and effect sizes were used for a magnitude-based inference analysis. Z-scores were also calculated to document worthwhile differences above or below the squad mean for the groups. The results showed no significant between-group differences for any of the performance tests. ST did have a worthwhile difference above the squad mean in the 0-10 and 0-30 m sprint intervals, while NST had a worthwhile difference below the squad mean in the 0-30 m interval. Physiological characteristics between ST and NST from the analyzed Division I squad were similar, although ST were generally faster. The similarities between ST and NST may be a function of the team's training, in that all players may complete the same workouts. Nonetheless, if all players exhibit similar physiological capacities, with appropriate substitutions by the coach a collegiate team should be able to maintain a high work-rate throughout a match.

- Abstract
Linear sprinting speed is an essential physical quality for many athletes. There are a number of different training modalities that can be used to improve sprint performance. Strength and conditioning coaches must select the most appropriate modalities for their athletes, taking into consideration the sprint distances that typically occur during competition. The study purpose was to perform a brief review as to the effect of specific (free sprinting; resisted sprinting by sleds, bands, or incline running; assisted sprinting with a towing device or a downhill slope), nonspecific (resistance and plyometric training), and combined (a combination of specific and nonspecific) training methods on different sprint distances (0-10, 0-20, 0-30, and 31+ m). A total of 48 studies fulfilled the inclusion criteria, resulting in 1,485 subjects from a range of athletic backgrounds. The training effects associated with specific sprint training were classified as moderate (effect size [ES] = -1.00; %change = -3.23). Generally, the effect of specific sprint training tended to decrease with distance, although the largest training effects were observed for the 31+ m distance. The greatest training effects (ES = -0.43; %change = -1.65) of nonspecific training were observed for the 31+ m distance. The combined training revealed greatest effects (ES = -0.59; %change = -2.81) for the 0-10 m distance. After this review, specific sprint training methods seem the most beneficial over the investigated distances. However, the implementation of nonspecific training methods (e.g., strength and power training) could also benefit speed and athletic performance.

- Abstract
This study investigated relationships between 10 m sprint acceleration, step kinematics (step length and frequency, contact and flight time), and leg muscle performance (power, stiffness, strength). Twenty-eight field sport athletes completed 10 m sprints that were timed and filmed. Velocity and step kinematics were measured for the 0-5, 5-10, and 0-10 m intervals to assess acceleration. Leg power was measured via countermovement jumps (CMJ), a five-bound test (5BT), and the reactive strength index (RSI) defined by 40 cm drop jumps. Leg stiffness was measured by bilateral and unilateral hopping. A three-repetition maximum squat determined strength. Pearson's correlations and stepwise regression (p ≤ 0.05) determined velocity, step kinematics, and leg muscle performance relationships. CMJ height correlated with and predicted velocity in all intervals (r = 0.40-0.54). The 5BT (5-10 and 0-10 m intervals) and RSI (5-10 m interval) also related to velocity (r = 0.37-0.47). Leg stiffness did not correlate with acceleration kinematics. Greater leg strength related to and predicted lower 0-5 m flight times (r = -0.46 to -0.51), and a longer 0-10 m step length (r = 0.38). Although results supported research emphasizing the value of leg power and strength for acceleration, the correlations and predictive relationships (r(2) = 0.14-0.29) tended to be low, which highlights the complex interaction between sprint technique and leg muscle performance. Nonetheless, given the established relationships between speed, leg power and strength, strength and conditioning coaches should ensure these qualities are expressed during acceleration in field sport athletes.

- Abstract
Dynamic stability is an essential physical component for team sport athletes. Certain Functional Movement Screen (FMS) exercises (deep squat; left- and right-leg hurdle step; left- and right-leg in-line lunge [ILL]; left- and right-leg active straight-leg raise; and trunk stability push-up [TSPU]) have been suggested as providing an indication of dynamic stability. No research has investigated relationships between these screens and an established test of dynamic stability such as the modified Star Excursion Balance Test (mSEBT), which measures lower-limb reach distance in posteromedial, medial, and anteromedial directions, in team sport athletes. Forty-one male and female team sport athletes completed the screens and the mSEBT. Participants were split into high-, intermediate-, and low-performing groups according to the mean of the excursions when both the left and right legs were used for the mSEBT stance. Any between-group differences in the screens and mSEBT were determined via a one-way analysis of variance with Bonferroni post hoc adjustment (p < 0.05). Data was pooled for a correlation analysis (p < 0.05). There were no between-group differences in any of the screens, and only two positive correlations between the screens and the mSEBT (TSPU and right stance leg posteromedial excursion, r = 0.37; left-leg ILL and left stance leg posteromedial excursion, r = 0.46). The mSEBT clearly indicated participants with different dynamic stability capabilities. In contrast to the mSEBT, the selected FMS exercises investigated in this study have a limited capacity to identify dynamic stability in team sport athletes.

- Abstract
Objectives: We aimed to investigate the association between methylenetetrahydrofolate reductase (MTHFR) C677T and endothelial nitric oxide synthase (eNOS) G894T polymorphisms with lipid peroxidation, total antioxidant capacity (TAC) and the risk of preeclampsia in preeclamptic women., Design and Methods: We screened a sample of 198 unrelated women with mild and severe forms of preeclampsia and 101 unrelated women with normal pregnancy with the eNOS and MTHFR variants using PCR-RFLP method. Also, the serum malondialdehyde (MDA) and TAC levels were determined using HPLC and commercial kits, respectively., Results: The frequency of combined genotypes of MTHFR CT and TT (CT+TT) and T allele tended to be higher in severe preeclamptic women compared to controls. There was no significant difference for eNOS G894T genotype and allele frequencies between patients and controls. A significantly higher level of triglycerides was observed in the presence of combined genotypes of MTHFR CT and TT and also eNOS GT and TT (GT+TT) in preeclamptic women compared to controls with the same genotype. Also, the presence of MTHFR TT genotype in severe preeclamptic women was significantly associated with the increased serum MDA level compared to CC genotype. In severe preeclamptic women the presence of CT and combined genotypes of CT and TT was significantly associated with the decreased TAC level compared to CC genotype. Also, a higher MDA level was observed in mild preeclamptic women with eNOS TT genotype compared to those with GG genotype but the difference was not significant., Conclusion: The present study indicates that MTHFR C677T polymorphism through affecting on TG level, lipid peroxidation and oxidative stress might be involved in the pathogenesis of severe preeclampsia., (Copyright © 2012 The Canadian Society of Clinical Chemists.

- Abstract
Sulfur mustard, a chemical warfare agent, has short- and long-term effects on various organs including respiratory system. Its late toxic effects on biological macromolecules among exposed veterans have not been well studied. We performed a study to determine paraoxonase-1 (PON1) activity and phenotype distribution as well as its correlation with albumin level in 289 male veterans with severe pulmonary complications who had exposure to sulfur mustard 20 years ago and in 66 age and ethnic matched healthy male subjects as controls. Serum albumin levels were lower in the veterans compared to controls (P < 0.001). Mean basal PON1 activity was 91.61 ± 44.80 U/mL in the veteran group versus 110.27 ± 50.23 U/mL in controls (P = 0.005). Arylesterase activity was not significantly different between the two groups. Paraoxonase to arylesterase activity ratio was significantly lower in the veterans as compared to controls (P = 0.005), mainly indicative of decreased PON1 activity rather the enzyme level. Significant reduction was found in serum albumin and PON1 activity with disease severity. Moreover, decreased high active BB (high activity) phenotype and increased intermediate active AB (moderate activity) phenotype were found in the veterans. This condition may lead to long-term accumulation of reactive oxygen metabolites resulting in a pro-oxidation milieu, which in turn can lead to increased peroxide levels and decreased antioxidant PON1 activity. In conclusion, lower serum PON1 activity and albumin might contribute to morbidity and occurrence of other complications such as atherosclerosis and rapid aging in the veterans suffering from late toxic effects of sulfur mustard.

- Abstract
The aim of the present study was to investigate the frequency and the possible association between thrombophilic mutations of factor V Leiden (FVL) and prothrombin G20210A with preeclampsia among Kurdish population of Western Iran. We studied 198 women with preeclampsia including 128 women with mild and 70 women with severe forms and 101 healthy pregnant women with uncomplicated pregnancy. Among cases there were 23 women with early onset preeclampsia and 175 cases with late-onset preeclampsia. The sample was genotyped by polymerase chain reaction-restriction fragment-length polymorphism using Mnl I and Hind III for FVL and prothrombin G20210A, respectively. The frequency of heterozygous FVL mutation was 7.6% among all preeclamptic women (8.6% in mild and 5.7% in severe preeclamptic women) and 7.9% in controls (P > 0.05). However, the prevalence of heterozygous FVL were 10.5 and 3.9% among severe preeclamptic women with early onset and late-onset preeclampsia, respectively (P > 0.05). The prevalence of prothrombin G20210A were 1.6, 2.9, and 3% among women with mild preeclamsia, severe preeclampsia and controls, respectively (P > 0.05). The level of serum triglycerides (TG) was significantly higher among women with preeclampsia compared to healthy pregnant women that was not associated with the two thrombophilic mutations. Our results indicate that neither FVL nor prothrombin G20210A could be a risk factor for preeclampsia in our population. However, high prevalence of FVL in preeclamptic women with early onset compared to those with late-onset preeclampsia may suggest a role for this mutation in predisposition to early onset preeclampsia that need to be confirmed with larger sample size.

- Abstract
Immobilization of human erythrocyte membrane was carried out by adsorption on Fractosil, a porous form of silica. Acetylcholinesterase (AChE) was chosen as a representative membrane enzyme in this study. Dependency of adsorption on membrane concentration was determined. Positive cooperative interactions that occurred in the process of immobilization increased stability. Presence of hydrophobic ligands on derivatized Fractosil was found to enhance stability of immobilized preparations making them more effective for use in continuous catalytic transformations. It is suggested that adsorptive immobilization of membrane structures such as the human erythrocyte membrane fragments on Fractosil and other inexpensive supports may provide a convenient procedure for utilization of their catalytic potential. Such preparations may be used in diagnostic kits or for construction of biosensors.

- Abstract
In contrast to the mature brain, Arrhenius plots of mitochondrial cytochrome c oxidase from newborn and old rat brain show no breaks (transition temperature); the apparent activation energy of the enzyme, in the physiological range of temperature, is also significantly higher. The results indicate deficient lipid-protein interaction as well as differential fluidity status in the inner mitochondrial membranes of the newborn and aged brain. These changes may contribute to the known deficiency in oxygen consumption of the newborn and old brain.
