The Safest Sprint Starting Position For American Football Players Essay

Punting a football can be intensively and precisely explained through the study of structural kinesiology. Punting is a skill that is often referred to as kicking. It is performed by releasing the ball from the hands and kicking the ball before it strikes the ground. Punting is an action that takes place in the sagittal plane around the frontal axis. The joints involved are the: atlantooccipital (cervical), intervertebral (lumbar), scapulothroracic (shoulder girdle) glenohumeral (shoulder) humeroulnar (elbow) radiocarpal (wrist) metacarpophalangeal and interphalangeal (fingers) acetabularfemoral (hip), tibiofemoral (knee), talocrural (ankle) and the metatarsophalangeal and interphalangeal (great and

This was the first study to knowledge that was done to associate head collisions relevance in youth football leagues with dissimilar coaching instruction programs. This study was one of the biggest models of youth football players to wear accelerometers throughout a complete youth football season. Largely, the study established that youth football players who partook in Heads Up Football associations received fewer collisions to the head per practice at both the 10g and 20g starting points. Over the progression of a 12-week youth football season with an average of 3 practices per week, this would compare to 90 less collisions over 20g or 36 lesser over 10g. These alterations were also continued when studying the 8- to 11-year and 12- to 15-year

Positions are important in every aspect of life, from lying in bed to driving a car. Where one being is in relation to another is extremely vital to the well-being and safety of those involved. In “What is the Safest Sprint Starting Position for American Football Players?,” an expository text about a scientific experiment, authors Bruno Bonnechere, Benoit Beyer, Marcel Rooze, and Jan Serge Van Sint claim that they have isolated the correct position American football players should use when playing. This optimal position is the one most likely to protect the players and prevent any severe head injuries from occurring on the field.

Anterior cruciate ligament (ACL) injury is a common sports injury occurs widely in the USA with the majority of suffering by healthy individuals with 70% of non contact period, during a variety of movements such as jump landing, cutting and pivoting (21). Different risk factors should be considered for injury, such as environmental, hormonal and biomechanical (18, 19). ACL injury prevalence is very high in soccer as well as other sports in females compared with males (29). Anterior shear force, valgus collapse, quadriceps to hamstring strength ratio (1, 21, 35, 37) are considered as other main risk factors in both genders. Co-contraction of the hamstring and quadriceps has been shown to provide dynamic stability to the frontal plane at the knee that protects maximum knee abduction loading (35). So, the main focus of the study should be on muscular strength between agonist –antagonist muscle of lower limbs and recovery after injury. Female athletes get injured almost 2-8 time higher than the male counterparts (1,5,7,19,21,24,29,33,35). Interesting point for comparing injuries in sports, dominancy of leg plays a role in ACL injury. In a non contact injury, females are more prone to get injured in their supporting leg, whereas male soccer athletes tend to injure the ACL in their preferred kicking leg (5). Biomechanical point of view, such as more extended hip-knee landing technique postures, knee pressure

The increase in the field of strength and conditioning knowledge has transitioned American Football into a game in which success is dependent on speed and explosiveness. “Running speed over short distances would appear fundamental to success in a number of field and court sports” (2). Coaches spend large quantities of time assessing players and their athletic qualities that underlie playing ability. Strength qualities athletes are highly variable, and are the determinant of their acceleration capabilities. Acceleration demands high force production in a short time period. There is a strong relationship between strength and running speed, resulting in a high level of interest to identify performance factors for different strength

The researchers chose to use a program called Dartfish 2D Pro Suite Software as a means of gathering their 2D data. The 3D analysis was conducted using a Vicon system. The subjects included sixteen healthy individuals, 9 males and 7 females with ages ranging from 21-30 years old. Before each participant performed the test, a member of the research team demonstrated the drop vertical jump (DVJ) using a 40 cm box. Each participant was given three practice jumps before the test began. Then, each participant had seven trials of the drop jump with less than one minute between each trial. Each trial was recorded with both 3D and 2D analysis. After the Frontal plane projection angle (FPPA), knee to ankle separation ratio (KASR), and knee separation distance (KSD) were measured for each subject based on the video recordings. They concluded that FPPA showed good interrater and intrarater reliability. It was determined that 2D analysis can be used as a cost-effective alternative to 3D analysis. However, of the four 2D techniques, KASR and KSD showed the best results. These two measurements were determined to be reliable, reproducible, and valid when compared with 3D measures. Although, if using 2D analysis, clinicians should be analyzed

(2002) used non-athletes (male physical education students) and tested the isokinetic torques of the hip extensors, knee extensors, and ankle plantar flexors. All joint torques were measure at angular velocities of 60/s, 120/s, and 180/s and were compared to jump performance. Jump performance was defined as the jump height and was measured with the countermovement jump and the squat jump. Tsiokanos et al. (2002) found a strong correlation between knee extensor peak torque (180/s) and countermovement jump height (r = 0.642, p < 0.01), which is in agreement with the findings from Harrison et al. (2013). Contrary to Harrison et al. (2013), Tsiokanos et al. (2002) found a moderate correlation between countermovement jump height and hip torques at

In the article, “Experience does not influence injury-related joint kinematics and kinetics in distance runners,” Agresta, Peacock, Housner, Zernicke, and Zendler are examining whether or not running experiences aides in the reduction of injury risk. The reason they decided to conduct this study is because early epidemiological studies and recent investigations have found that novice runners have a higher injury rate when compared to recreational runners and ultra-marathon runners. Among runners, the knee tends to be where the injuries occur. Yet, they do note the healthy runner effect bias in which the injury prone runners discontinue running, so the healthy runners accumulate the most experience. Nevertheless, they hypothesize that injuries

Running has fast become a popular physical activity and is enjoyed by most everyone. People are finding a healthier lifestyle by controlling their weight and improving cardio capacity from running, however, running is a high impact exercise that can lead to injuries. In addition to high impact injuries, overuse injuries due to the amount of runs, the duration and distance along with speed are the most common. Environmental factors such as running surfaces, grass, concrete, blacktop, rock/dirt terrain can contribute to these injuries. Despite the health benefits

Many research studies have been conducted till date to investigate the effects of static stretching on lower limb force production and agility in athletes. As contrary to the popular belief, most of the research data suggest that static stretching immediately prior to a competition enhances the rate of injuries instead of reducing them. An acute bout of stretching does not improve force production and agility in basketball players. When maximal velocity contraction, power, jump height, jump force, and jump velocity were measured after static stretching, it was observed that the session

This essay discusses, high school football players are very likely to get injured towards ending season more than football college players for various reasons. A research associate said, “there are ways to reduce the number and severity of football injuries through targeted intervention.” (resource 1) There were high levels of knee and ankle injuries, due to ligament sprains. A way that can help to improve on those types of injuries would be stretching exercises. The positions that run a higher risk of being injured would be the running backs and linebackers. “Football is the number one leading cause of sports related injuries.”(resource 1)

Figure 1.4 it shows subject Ar’s back is hunched forward with his head not aligned with his body. Subject A’s head should be neutral, with his shoulders back and down, which allows for a natural spinal curve that assist in maintaining stability of the torso while sprinting (Mero, 1992).

Biomechanics refers to the movement and structure of living organisms. It allows for a better knowledge regarding the human body and how numerous internal and external forces affect movement. For those who participate in sport, biomechanics can greatly enhance performance by improving both skills and techniques critical to specific sports. With the ongoing growth and development of sport, biomechanics is continuing to become a significant focus. This paper will focus on the biomechanics of soccer concerning the defining action of the game, kicking. It will focus its attention on the biomechanical differences in soccer kicking with the preferred and the non-preferred leg, the influence maturation has on the instep kick of female soccer athletes, the kinetic comparisons of side-foot soccer kick between experienced and inexperienced players and the kinematic instep kicking differences between elite female and male soccer players.

Research from Mayo Clinic states that side to side and equal flexibility is probably the most important for average athletes (“Stretching Essentials”). With a lot of sports, athletes push off from side to side in fast and explosive movements. If the body is not prepared for fast movements, a harmful outcome could result.
