Caffeine-containing energy drink improves physical performance in female soccer players

There is little information about the effects of caffeine intake on female team-sport performance. The aim of this study was to investigate the effectiveness of a caffeine-containing energy drink to improve physical performance in female soccer players during a simulated game. A double-blind, placebo controlled and randomized experimental design was used in this investigation. In two different sessions, 18 women soccer players ingested 3 mg of caffeine/kg in the form of an energy drink or an identical drink with no caffeine content (placebo). After 60 min, they performed a countermovement jump (CMJ) and a 7 × 30 m sprint test followed by a simulated soccer match (2 × 40 min). Individual running distance and speed were measured using GPS devices. In comparison to the placebo drink, the ingestion of the caffeinated energy drink increased the CMJ height (26.6 ± 4.0 vs 27.4 ± 3.8 cm; P < 0.05) and the average peak running speed during the sprint test (24.2 ± 1.6 vs 24.5 ± 1.7 km/h; P < 0.05). During the simulated match, the energy drink increased the total running distance (6,631 ± 1,618 vs 7,087 ± 1,501 m; P < 0.05), the number of sprints bouts (16 ± 9 vs 21 ± 13; P < 0.05) and the running distance covered at >18 km/h (161 ± 99 vs 216 ± 103 m; P < 0.05). The ingestion of the energy drink did not affect the prevalence of negative side effects after the game. An energy drink with a dose equivalent to 3 mg of caffeine/kg might be an effective ergogenic aid to improve physical performance in female soccer players.

Exploring the value of a coach intervention process within women's youth soccer: A case study

A coach intervention process was explored with a 38-year-old female youth soccer coach. The experimental research design consisted of a baseline assessment, intervention and follow-up phase. Within each phase, the coaching practices were assessed using the Coaching Behaviour Assessment System. Additionally, measures of both coach and athlete perceptions and attitudes were also recorded. The results revealed no significant change in coach behaviours from the baseline assessment to the follow-up assessment. However, although not significant, a meaningful change particularly regarding the use of Reinforcement, General Technical Instruction and Mistake Contingent Encouragement was evident. Results of the descriptive-analytic data generated from the cognitive investigations highlighted generally positive although not statistically significant changes, particularly those concerning the athletes' attitudes towards their coach, teammates and soccer, following the intervention process. The findings of this study are discussed in line with the existing coach behaviour literature.

Beauty, effort and talent: a brief history of Brazilian women’s soccer in press discourse

This essay offers a brief historical background to the evolution of women’s soccer in Brazil. It focuses on the main obstacles women faced to pursue the game, which was forbidden to women in Brazil in 1941. By analysing how the newspapers treat women’s teams, the essay will try to highlight significant changes in the stereotypes that long guided perceptions of people about women soccer players.

Application of the Copenhagen Soccer Test in high-level women players – locomotor activities, physiological response and sprint performance

We evaluated the physiological response, sprint performance and technical ability in various phases of the Copenhagen Soccer Test for Women (CSTw) and investigated whether the locomotor activities of the CSTw were comparable to competitive match-play (CM). Physiological measurements and physical/technical assessments were performed during CSTw for eleven Norwegian high-level women soccer players. The activity pattern during CSTw and CM was monitored using the ZXY tracking system. No differences were observed between CSTw and CM with regards to total distance covered (10093±94 and 9674±191m), high intensity running (1278±67 and 1193±115m) or sprinting (422±55 and 372±46m) (p>.05). During CSTw, average HR was 85±2%HRmax with 35±2% playing time >90%HRmax. Blood lactate increased (p<.05) from 1.4±0.3mM at rest to an average of 4.7±0.5mM during CSTw, with no changes during the test. Blood glucose was 5.4±0.3mM at rest and remained unaltered during CSTw. Sprint performance (2×20m) decreased (p<.05) by 3% during CSTw (8.19±0.06–8.47±0.10s). In conclusion, the locomotor activities during CSTw were comparable to that of high-level competitive match-play. The physiological demands of the CSTw were high, with no changes in heart rate, blood lactate or technical performance during the test, but a lowered sprint performance towards the end of the test.

Performance and Muscle Architecture Comparisons Between Starters and Nonstarters in National Collegiate Athletic Association Division I Women's Soccer

This study compared performance and muscle architecture (MA) changes in starters (S) and nonstarters (NS) during a National Collegiate Athletic Association Division I women's soccer season. Twenty-eight women (19.9 ± 1.1 years; 1.71 ± 0.08 m; 64.7 ± 6.4 kg) were monitored for vertical jump power (VJP), repeated line drills (LDs), 3-dimensional multiple object tracking (3D-MOT), and reaction time (RT) at preseason, midseason, and postseason. Muscle architecture changes using ultrasonography were assessed at preseason and postseason. Comparisons between S (n = 11; 70.0 ± 14.6 min per game) and NS (n = 17; 8.4 ± 8.0 min per game) were performed to make magnitude-based inferences. No differences were seen in VJP during the season in either group. Starters were more likely (81.1%) to decrease LD time than NS, with no differences in fatigue rate. Starters and NS improved 3D-MOT (1.14 ± 0.41 to 1.55 ± 0.43) and RT (0.37 ± 0.05 to 0.34 ± 0.33 seconds), with no differences between groups. Rectus femoris (RF) echo intensity improved (65.57 ± 1.50 to 61.26 ± 1.59) in both groups, with no interactions observed. Cross-sectional area (20.84 ± 3.58 to 21.46 ± 3.66 cm) increased and pennation angle (PANG) (12.58 ± 2.56 to 11.78 ± 2.03°) decreased for both groups in the vastus lateralis (VL). Muscle architecture comparisons between groups revealed S likely decreased VL muscle thickness (MT) and PANG (81.6 and 79.4%, respectively) and possibly decreased RF MT and PANG (65.7 and 59.4%, respectively) when compared with NS. Results indicate that VJP and LD fatigue rate are not changed during a competitive season, but S become faster than NS. Three-dimensional multiple object tracking and RT improve regardless of playing time. Changes in MA indicate that practices alone provide sufficient stimulus for improving muscle quality during the competitive season.

The Impact of an Educational Intervention on College Athletes' Knowledge of Concussions

The purpose of this study was to determine college athletes' knowledge regarding concussions and to determine if an educational lecture before their sport season would improve their knowledge and reporting of concussions. Cross-sectional study. University classroom. Seventy National College Athletic Association Division II men's/women's soccer players and men's/women's basketball players. Educational lecture regarding the basics of concussions. Descriptive statistics, ANOVAs, and a paired sample t test determined the athletes' knowledge of concussion before and after the season and the impact of the educational intervention. A paired sample t test indicated that the athletes scored better on the postseason concussion knowledge assessment [t(49) = 10.34, P < 0.000, d = 1.47]. After an educational intervention, athletes demonstrated an improvement in their knowledge on concussions.

Goal Setting with a College Soccer Team: What Went Right, and Less-Than-Right

Coaches report using goals, but often employ only broad (i.e., win) or long-range (i.e., national championship) goals without lower-level goals. To provide smaller steps along the way to long-term goals, a goal setting program was instituted with a women's college soccer team. Three levels of goals (i.e., individual, position group, and team) were utilized for one competitive season. The framework and impacts of the goal setting program are explained and discussed across all three levels from the perspective of the athletes, the coaching staff, and the sport psychology consultant. All three levels of goals produced both positive and negative outcomes.

No Effect of a Single Remote Voluntary Contraction on Performance in Women Soccer Players

Remote voluntary contractions (RVCs) are defined as muscle contractions remote from, yet concurrent with, the prime mover. Previous studies suggest this phenomenon may produce an ergogenic effect on performance. Currently, little research has examined the effects of a single RVC on complex performance in women athletes. The purpose of this study was to examine the effect of RVC on kick velocity and throw-in velocity in women soccer players. Fourteen women with competitive soccer experience in the past 2 years participated. Subjects performed 3 maximal effort kicks and 3 maximal effort throw-ins with and without RVC. The RVC condition consisted of maximal jaw clenching on a mouth guard during the concentric phase of each kick and each throw-in. During the control condition (CON), subjects were instructed to keep their mouths open, and no mouth guards were used. Analyses demonstrated RVC had no effect on kick velocity (CON: 65.65 ± 8.38 km·hr(-1), RVC: 66.90 ± 9.40 km·hr(-1) or throw-in velocity (CON: 49.55 ± 5.65 km·hr(-1), RVC: 49.31 ± 3.81 km·hr(-1)). In conclusion, RVC via jaw clenching does not appear to enhance or negate kick or throw-in velocity in women soccer players. Therefore, athletes and coaches may choose to use mouth guards as they see fit.

Isokinetic Strength and Performance in Collegiate Women's Soccer.

Soccer research in exercise science has focused on men's soccer, while women's soccer has been underrepresented in training studies, as well as in studies focusing on physiological variables. The purpose of this study was to examine anthropometric data and selected physiological and biomechanical variables of importance as they correlates to performance variables such as ball velocity and distance, specifically in female collegiate soccer players. Twenty-two NCAA Division I female soccer athletes participated in the study. Body composition, muscular strength, explosive power, aerobic power, acceleration, speed, and agility were tested in each athlete. Knee torque (KT) and hip torque (HT) were also measured on both legs. Kicking accuracy and velocity were examined. A correlation was found between KT and KV (r=0.93), as well as vertical jump and KV (r=0.91). Aerobic power (r=0.93), agility (r=0.88), and vertical jump (r=0.84) were highly correlated to BF%. These data suggest that significant relationships do exist between peak knee and hip torque, agility, lean body mass, strength, and explosive power with soccer-specific variables such as kick velocity (KV). Contributing to the body of data on female soccer athletes and variables important in performance is essential as the population engaged in the sport continues to increase.

Monitoring and Prevention of Anemia Relying on Nutrition and Environmental Conditions in Sports

Conflict of interest: none declared.IntroductionAnemia is a blood disorder characterized by abnormally low levels of healthy red blood cells or reduced hemoglobin, the iron-bearing protein in red blood cells that delivers oxygen to tissues throughout the body. The most common symptoms of this disorder are fatigue, weakness and, in extreme cases, shortness of breath or palpitations, or you may have no symptoms at all. Sports anemia is a term loosely applied to a least three different conditions: hemodilution, iron deficiency anemia and foot-strike anemia. Not exclusive to athletes, iron deficiency anemia occurs most often among women who may lose more iron each month when they menstruate than they take in.Material and MethodsTherefore, we examined its effect on the physical condition of female athletes. Several years (since 2010th until 2012th), we studied how anemia among girls (pioneers, juniors and seniors categories) that are involved in sports (women’s soccer, volleyball and handball) in Rasina’s district (Serbia), affecting their physical fitness. When their trainers approach to us, complaining that they have players who are great, so extraordinary talents, but by no means able to withstand more than twenty minutes in the game, we suggest them to perform laboratory tests. It was tested 134th female athletes.Results and DiscussionAnemia was observed in 43. (9. pioneers, 19. juniors and 15. seniors). So, laboratory results showed that in these girls anemia causes poor sport condition. After that, the girls enhanced nutrition. Their diet consisted of iron supplements and vitamins. Altitude training was organized for them, also. After all these treatments, condition significantly improved. It was first time that trainers in Rasina’s district realizing significance of laboratory tests.

Practice Injury Rates in Collegiate Sports

The objective of this article was to explore the differences in practice injury rates for select National Collegiate Athletic Association (NCAA) sports within and across sport by preseason, in-season, and postseason. This article will explore the relationship of practice injury rates by fall, winter, and spring sports as well as by Divisions I, II, and III. Descriptive epidemiology study. NCAA schools. NCAA athletes. Injury. In all sports across all seasons, preseason practice injury rates [6.3 per 1000 athletic exposure (A-E)] were higher than in-season (2.3 per 1000 A-E). Fall sports had an overall preseason practice injury rate of 7.4 (per 1000 A-E) compared with 7.0 (per 1000 A-E) for winter and 3.5 (per 1000 A-E) for spring sports. Women's soccer had the highest preseason injury rate of 9.5 (per 1000 A-E). Men's football had the highest increased risk of injury comparing preseason with in-season practice injury (3.47 per 1000 A-E). The recognition that preseason practice injury rates are higher compared with in-season and postseason practice injury rates can create an opportunity for athletes, coaches, and medical personnel to identify prevention strategies to reduce preseason injury risk.

Iranian Women’s Sports Fandom

As sport enters new global territories, attending to questions of cultural difference is increasingly important to studies of women’s sports fanship. This article draws on theories of transnational feminism and feminist sports scholarship to contemplate the cinematic portrayal of the non-Western female football supporter. Women sports fans rarely appear as film protagonists, with the notable exception of the 2006 movie Offside, which tells the story of Iranian women soccer fans attending a World Cup qualifying match. By focusing on the ways that women fans negotiate their marginal status in the sporting arena, I argue that the film unsettles cultural associations between masculinity and football in Iran, and confounds the oppositional construction of the “other” woman as a passive victim of, or freedom fighter against, Islam.

Examining the diagnostic accuracy of dynamic postural stability measures in differentiating among ankle instability status

BackgroundDynamic postural stability is defined as the ability to transition from a dynamic movement to a stable condition over one's base of support. Measures of dynamic stability have been used extensively to classify ankle instability status and assist clinicians with ankle injury interventions. Therefore, the purpose of this study was to determine if current methods of quantifying dynamic stability are accurate in differentiating among healthy, coper, and unstable ankles. MethodsOne hundred ninety four Division-I collegiate athletes (football, volleyball, field hockey, men's/women's soccer, men's/women's lacrosse, men's/women's basketball) volunteered for this study. Participants were categorized into healthy, coper, and stable groups by a self-reported questionnaire and previous history of ankle injuries. Dynamic postural stability was assessed using the Multi-Directional Dynamic Stability Protocol by jumping and landing single-legged onto a force platform from four different directions. Receiver operator curves were used to analyze the accuracy of current techniques of calculating dynamic stability among groups. FindingsNone of the existing methods were found to be accurate in differentiating ankle instability status in any of the jump landings. InterpretationResearchers have commonly used these existing methods to quantify dynamic postural stability. None of the current calculation techniques worked with our jump landing protocol. Researchers need to pay attention to the protocol and calculation technique pairings in that using inaccurate measures of dynamic postural stability makes any findings of that research ineffective. Therefore, this challenges researchers to develop a more accurate calculation to quantify dynamic postural stability, or develop a jump landing protocol that exposes sensorimotor deficits in the more able-bodied population.

Functional hamstrings: quadriceps ratios in elite women's soccer players

We compared starters and non-starters for various isokinetic strength variables in elite women’s soccer players. A convenience sample of 10 starters (mean ± s; age = 20 ± 2 years; height = 170 ± 4 cm; body mass = 65 ± 5 kg) and 7 non-starters (age = 20 ± 1 years; height = 164 ± 3 cm; body mass = 63 ± 4 kg) performed maximal voluntary muscle actions of the leg extensors (concentric) and flexors (eccentric) on an isokinetic dynamometer in order to measure concentric peak torque for the leg extensors, eccentric peak torque for the leg flexors, and the functional hamstrings:quadriceps (H:Q) ratio at 1.047 rad · s-1 and 4.189 rad · s-1 concentric peak torque for the leg extensors was not different between starters and non-starters. However, it was greater at 1.047 rad · s-1 than at 4.189 rad · s-1 in both groups. Eccentric peak torque for the leg flexors was greater for the starters versus non-starters at 4.189 rad · s-1. Eccentric strength of the leg flexors at fast movement velocities may be used as an effective physiological profile and may discriminate between playing status in elite women’s soccer players.

Beyond Bend it like Beckham: the global phenomenon of women's soccer

Though it burst into public consciousness only with the 1999 World Cup, women's soccer has been around almost as long as its male counterpart, flourishing in England during and after World War I. From the rise of women's soccer following Title IX legislation in the early seventies to the watershed 1999 World Cup performance that turned the American team into instant celebrities, soccer is now the most popular sport for girls and women, with participation growing exponentially worldwide. Beyond Bend It Like Beckham presents the first in-depth global analysis of the women's game-both where it has come from and where it is headed. With commentary from key players, coaches, and administrators, Timothy F. Grainey follows the sport's reach into the unlikeliest places today, even countries where women were banned from playing soccer just a few short years ago. Though women in the United States and Canada still fight for equal treatment and funding, their situations differs markedly from the hostility, abuse, and even outright bans that some women still encounter in trying to pursue an activity they love. Through the prism of soccer, this book explores the struggle for women's rights abroad, in countries as diverse as Sweden, Russia, South Africa, Pakistan, Australia, and Iran.

Congenital Adrenal Hyperplasia in an Elite Female Soccer Player; What Sports Medicine Clinicians Should Know about This?

Congenital Adrenal Hyperplasia (CAH) refers to a group of congenital conditions characterized by disordered cortisol synthesis. The correlation between CAH and sports performance has been less studied before and there is very limited information regarding the impacts of this congenital disease on sports performance. Probably, there are some limitations for patients who suffer from CAH in sports, but at the same time, they may enjoy some advantage due to the probable effect of endogenous hyperandrogenism on their exercise performance. The case is a 14 - year old girl with male phenotype who is a known case of congenital adrenal hyperplasia. She plays in the women's national soccer team of under 16. She has been in the first division league of indoor soccer for 4 years and was also selected in the preparation training camp of women's football team for Singapore's youth Olympic Games. Her illness and dependence on corticosteroid have caused some concerns for her participation in the international competitions of women. However, following consultations with the Therapeutic Use Exemption (TUE) Committee of games organization, she received TUE to use corticosteroid only within the games period. Despite all her problems, she is now playing in the Second Division League of indoor soccer. A female adolescent with CAH may compete at the high level of outdoor and indoor soccer. However, there are many questions regarding the advantages and disadvantages of this congenital disorder and its treatment on sports related issues.

Influences of player nationality, playing position, and height on relative age effects at women's under-17 FIFA World Cup

Previous research has shown that young male soccer players who are born early in a cohort are overrepresented on elite soccer teams. Selection advantages such as this have been termed ‘relative age effects’ (RAEs). Few studies have examined RAEs in elite women's youth soccer. Therefore, the aim of this study is to investigate the occurrence of RAEs in the Fédération Internationale de Football Association (FIFA) U-17 Women's World Cup competition and their link to playing positions. In the entire cohort of 672 players, we found significant RAEs in the geographical zones of Europe and North and Central America, no RAEs in the zones of Asia, Oceania, and South America, and significant inverse RAEs in the zone of Africa. Additionally, significant RAEs were found for goalkeepers and defenders from Europe and North and Central America. Inverse RAEs occurred for African goalkeepers, defenders, and strikers. Goalkeepers of all zones were significantly taller than players of all other playing positions. The results of this study show that remarkable RAEs do exist at elite women's youth soccer. Similar to men's soccer, there is a bias toward the inclusion of relatively older players, and a link between RAEs and playing positions.
