Soccer is the most playing sport worldwide, with 275 million players of either gender and of all ages. In terms of incidence rates in professional players, soccer leads to to 3.4 injuries per 1000 training hours and 21.9 injuries per 1000 match hours (). Hamstring strain are common injuries in soccer players, typically occur during sprinting, with a high recurrence rate (11–30%), that lead to an incapability to play soccer till up to 90 days (). A recurrent hamstring injury (RHI) is delineated as an injury of the same site and same type of hamstring and which occurs after a player’s return to play (). A particular difficulty observed from an injury prevention point of view is that hamstring injury risk factors are heterogeneous. It has been proposed that the interaction between non-modifiable risk factors, such as previous history of injury and increasing age, and modifiable factors, such as strength, needs to be reasoned. The most emerging evidence reaffirms persuading early muscle activation, especially eccentric strengthening exercises moving through an entire range of optimal muscle length have been shown more effective in stimulating compatible adaptation to loading and becoming the mainstay of injury prevention and rehabilitation programme for RHI (). The aim of this essay is to explore evidences of interaction between various risk factors and eccentric hamstring strength in determining the risk of hamstring injury. It also discusses the efficacy of eccentric
It has been recognised that there is a wide continuum of hamstring injuries that occur in football (5). These consisting of strains, partial and complete hamstring avulsions (5). Two different types of acute HS have been observed, one during high-speed running involving the BF, and the second during movements of vast lengthening movements such as high kicking and slide tackling which involves the SB predominately (6). When looking at the sprinting aspects of football HS occur when the muscle fails structurally due to the intense eccentric loading that occurs (7).
Studies have also shown that women in particular, unfortunately have a disadvantage in life when compared to male counterparts, and that is one pertaining to their higher risk for ACL injury. Due to a neuromuscular imbalance that is concomitant with overactive quadriceps strength compared to hamstring strength, females tend to place more stress on the ACL. Accordingly, this increases the pressure on the ACL leading to a higher prevalence of injury that will arise more on the female spectrum than that of the male (Myer et al., 2009). Furthermore, this is important to be aware of for female athletes and for the Physical Therapists who treat them in efforts to provide educational information regarding the relationship of stronger hamstrings correlating to a lesser chance of ACL injury. Personally, I have worked with athletic females in the past as a personal trainer and while I was not strengthening hamstrings with the direct objective to prevent an ACL injury, I was cognizant of the notion that a balanced quadriceps and hamstring ratio was necessary to avoid lower extremity injuries as a
When you think of the Olympics, you most likely think of gymnastics, soccer, swimming, hockey and many more events. However, very few of the sports that are competed in now existed when the Olympics first began. They have evolved considerably over the last 3,000 years. First of all, there were very few events compared to how many there are now. Also, the Olympics went from only being known in Greece to being “the world’s preeminent sporting competition.” (History.com)
Professional football has been “the most popular sport in America for thirty straight years” (Nussbaum). Sundays have become a day, in which football fans spend it lounging in front of their television, cheering on their favorite team. Many people love the game of football and dedicate a lot of time towards watching it. However, other people are starting to get concerned over the injuries, such as concussions and chronic traumatic encephalopathy (CTE), associated with the game. A writer for The Atlantic, Jeff Nussbaum, released an article called, “How to Bring Pro Football Into the 21st Century”, about the dangers of football and his belief that the National Football League should make changes to some rules, to prevent future injuries.
Our study proposes to examine the effects of a training program on high school female soccer athletes in regards to their risk for an anterior cruciate ligament (ACL) tear using surrogate markers. A randomized control trial will be employed on eligible female soccer athletes that are age fourteen to eighteen taken from two different schools. We will be using a convenience sample with one school being the control group and the other being the experimental group having a total of 56 participants after accounting for attrition. A seven question screener survey was created for this experiment to help screen out possible confounders. Data will be gathered by careful measuring of the exercises performed. More specifically, weight increase, range of motion increase, and repetitions performed. A proportion test will be used to analyze the data. The purpose of this study is to determine if, at the high school level, a specialized exercise program will help decrease the chance of ACL tears through strengthening the hamstrings.
In a prospective randomized controlled trial Askling (2014) compared the effectiveness of lengthening exercises program and conventional exercises program on rehabilitation of acute hamstring injury. Forty-six Swedish sprinters and 10 jumpers with hamstring injuries confirmed by MRI were recruited and assigned unsystematically to lengthening exercises protocol (L-protocol) or conventional exercises protocol (C-protocol). The outcome measurements that used in this study were the number of day to return to sport and the rate of re-injury during 12 months. All participants were evaluated for flexibility and strength, using manual assessment, within two days post injury, and Askling H-test was used at the end of he rehabilitation before allowing athletes to return to sport.
Sherry et al (2004) combared the effectivness of two rehablitation programes in treatment of acute hamestring straines using time required to return to play and recurent of injury in the first two weeks and within the first-yeare as mesurments. Twenty-four prticipantes were recuruated and allocated randomly to group one (STST) which incloud static stretching, isolated progressive hamstring resistance exercise, and icing and group two (PATS) which consists from progressive agility and trunk stabilization exercises and icing. The treatment protocols were divided into two phase in both groups and the subjects progressed from stage one to stage two when they could perform high knee march in place without pain as well as walking with the same stride length and stance time on both injured and uninjured leg. Additionally, the athletes were allowed to return to play if they exhibited 5/5 manual muscle strength of knee flexion, had no tenderness with
As previously mentioned most ACL injuries happen from non-contact. The differences in lower extremities between genders are possible risk factors for ACL injuries during sports participation (Yu et al., 2005). Yu et al., (2005) compare the difference between genders in lower extremity motion of adolescent soccer players between ages of eleven and sixteen. Focusing on knee flexion and hip flexion the results showed that young female soccer players had both decreased knee and hip angles at ground contact and decreased knee and hip flexion motions during the landing of the stop-jump task. Yu et al., (2005) demonstrated that landing with a smaller knee flexion angles could have increase load on the ACL, concluding that these changes occur after the age of 12 and increase with age. In addition, females with smaller knee flexion can limit their sagittal plane motion when landing, increasing their ACL risk even more (Pollard, Sigward, & Powers, 2010). A clear difference in the knee and hip flexion was shown based on female and male
Previous investigations have shown relationships between external workload and injury, this study however takes into consideration the acute and chronic workloads. When acute workloads outweighed chronic workloads a higher incidence of injury was observed, challenging coaches to monitor and alter training loads. In contrast, high chronic external workloads were seen to lower injury risk reiterating the positive physical adaptations of training. Finally, the need to assess recovery strategies is fundamental due to the high rate of injuries in weeks following assessment.
Exclusion Criteria The exclusion criteria included any acute and chronic lower extremity injuries last 3 months. Equipment Champion Sports Watch model GT14-AG8740-C9-INST-PKG-R02 was used to time the subjects sprint test, as there was no access to Speed Gate equipment, a second assessor, with the same sports watch brand and model, was used for reliability of time. Cones were used to mark out the start and finish distance of 10 yards for the dynamic warm up and 10, 20 and 40 yards for the sprint test. The subjects
Often during sport activity, injuries can occur in the muscles due to a variety of reasons such as; poor motor function, lack of recovery, or inflammation (Curran). A common objective for athletes and coaches alike is to eliminate the chance of developing injuries and maintain the ability to continuously perform at a high level throughout the season which can last up to 10 months. Otherwise the athletes’ physical and technical performance can suffer.
Female soccer athletes from 13 universities were evaluated over 5 competitive seasons for injury incidence, injury category, time of injury, injury time loss, player position, injury mechanism and situation, primary type of injury, injury grade and anatomic location, field location at the time of injury, injury severity, head and lower extremity trauma, cleat design, turf age, and environmental factors. In total, 797 games were evaluated with a total of 693 injuries. 272 occured on FieldTurf and 421 on natural grass. . A significantly lower total injury incidence rate of 7.7 (95% confidence interval [CI], 7.2-8.1) versus 9.5 (95% CI, 9.3-9.7) (P = .0001) and lower rate of substantial injuries, 0.7 (95% CI, 0.5-1.0) versus 1.5 (95% CI, 1.2-1.9) (P = .001) were reported on FieldTurf versus natural grass. The study concluded that FieldTurf is a practical alternative when comparing injuries in collegiate women’s
Football. The most watched sport in the world. And we’re not talking about the football with the Mannings, Deflategate, and Adrian Peterson. What’s being talked about is what Europe and most of the world call football, but America calls it soccer. Soccer was first invented in China in 300 B.C, where kids would kick leather balls by kicking it into a small net. Greeks and Romans played soccer for fun, but it wasn’t until the 18th century when people would start to play soccer as a full-time game. Football was first introduced to the Olympics in the 1900 Summer Olympics after the sport wasn’t in the 1896 Olympics. Women’s football, however, wasn’t in the Olympics until 1996. Many American kids and other players have played soccer in leagues by the time soccer was introduced into the Olympics, but men that wanted to go pro would have to move to Europe to play until 1993 when America’s MLS began. But this article isn’t about the history of soccer. This article is about one of the biggest rivalries in sports history since the question of is Lebron James better than Michael Jordan. The question is who’s the better player: Cristiano Ronaldo or Lionel Messi. Even though they play for different teams, are in different leagues, and both want the title for best player, they do have a lot in common. Ronaldo is only two years older than Messi, and both didn’t grow up with a lot. Both athletes started by a young age, and both made it to professional and national teams before most
In a day of technology, most kids being born into the world are almost born with a sixth sense which is how to use any type of technology. With the millions of different things you can do with technology most kids spend way too much time using their devices. Due to all this technology use kids don’t seem to be outside playing and having fun as they once did. Kids use to be always outside playing sports and running around with their friends but since the rapid evolution of technology kids have sadly started to stay inside. “According to the 2005 GSS, boys aged 5 to 14 are still more likely to participate in sports than girls the same age, but the gap is narrowing. Sports participation of boys has declined from 66% in 1992 to 56% in 2005. Over the same time period, sports participation of girls has changed little from 49% to 45%.” These statistics can easily be blamed on the evolution of technology. This essay is going to persuade you on why every kid should play team sports throughout their later years of elementary school and through high school. Most kids growing up in the 90’s and early 2000’s were always outside running around and playing with their friends. The kids didn 't only do this because it was fun but because it was one of our only sources of entertainment growing up and even though technology was around it was as advanced as it is today. Team sports is one of the main things these kids would be doing all the time. It benefited kids in numerous ways that not only
