The increase in participation in sports among children and adolescents has led to an increase in sports related injuries; therefore, increasing the use of physiotherapy and taping. Taping has been used by physical therapists to rehabilitate injuries and stabilize the patella. The purpose is to lessen the intensity of the pain or the likelihood of recurrent injuries on the knee post-injury; especially if the athlete chooses to continue their participation sports. In most studies, knee injuries result
first half of swing, rectus femoris force increased with running speed in response to larger moments required in hip flexion and knee extension. Whereas during stance, it produced a knee-extensor moment to complement the action of the combined Vastus medialis, intermedius, and lateralis. Also during acceleration, iliopsoas , gluteus maximus, gluteus medius, hamstrings, and rectus femoris all developed significantly larger peak forces throughout the stride cycle. Specifically, the peak forces of gluteus

The knee joint is extended when in the standing position, to stabilize this joint the biceps femoris, semi-mebranosus, semi-tendonosus (hamstrings) and the rectus femoris, vastus lateralis, vastus intermedius and vastus medialis (quadriceps) co-contract isometrically. The vertebral column of the body remains stable due to the isometric co-contraction of the erector spinae, rectus abdominus and the e... ... middle of paper ... ...training/two
The next criteria is the dynamics of the effort which states that the effort during training has to be equal to or exceed the effort of the skill itself (Siff & Verkhoshansky, 2009). The horizontal velocity at take-off was at 3.55m/s (Krüger et al., 2003). In another study horizontal velocity at take-off was at 4.19m/s and Vertical velocity at take-off was at 2.07m/s with a peak horizontal force of 699N and a vertical force of 1365.12N (Benjanuvatra, Lytue, Blanksby & Larkin, 2008). Dynamics of the
hips by eccentric contraction in the gluteus maximus, semimembranosus, Semitendinosus, and Biceps Femoris. In this downward movement, the knees are flexed causing a concentric contraction at ……… degrees on the Rectus Femoris, Vastus medialis, vastus intermedius, and vastus lateralis. The flexed knee also causes an eccentric contraction on the hamstring on the bicep femoris, semitendinosus, semimembranosus. Whilst the lower body is in a bend position, the upper body such as the shoulder girdle are
Suppleness in Physical Education The definition of flexibility, suppleness and mobility is the range of movement possible round a joint and this depends on the amount of stretch allowed by the ligaments, joints, tendons and muscles. Flexibility is an important component of physical fitness for all athletes as increasing your flexibility aids performance and helps to avoid unnecessary injury. It is impossible to have the same degree of flexibility around all joints as the joint structure
Abstract The focus of this paper is mechanically and automatically break down the deadlift. It focuses on the four phases of the deadlift (The lift off, pull through, the lockout, and the lowering phase) as well as the muscles involved in lifting and lowering the load. The sole purpose of the deadlift is for health and fitness. It is a core lift that works nearly every muscle in the body. Muscles from the lower and upper extremities will go through a period of flexion and extension when moving
hamstrings collaborate with the gluteus maximus to lengthen the hips throughout the initial and final stand. The quadriceps contributes in the act and also helps with the extension of the knee and as a stabilizer for the knee. The vastus lateralis, vastus intermedius, vastus medialis and rectus femoris work together to start with the initial pull and standing movement, which extends the knee. He uses his calves, synergist to knee extension, entailing the soleus and the gastrocnemius while planter flexing

Hip and Knee Movements Hip and Knee Movements 1. Take the position of a runner in the starting block for a short running race. Place one foot forward and one foot back while placing your hands on the starting line. a. In what position is the hip joint for the forward leg? Flexion and extension can be measured by analyzing the angles between two body parts. Flexion can be described as a movement that decreases the angle between two parts of a body. On the other hand, extension describes to
For individuals over the age of 50, osteoarthritis (OA) of the knee is the leading cause of chronic disability (Bruce-Brand). Neuromuscular electrical stimulation (NMES) is a commonly used modality in physical therapy practice for increasing the strength of muscles. There is no cure for OA, but quadriceps strength is highly correlated with functional performance of the knee and, therefore, increasing quadriceps strength may lead to improvements in knee performance and quality of life for those with

You can strengthen the quadriceps muscles specifically the vastus medialis and vastus lateralis or you can focus on strengthening ... ... middle of paper ... ...cated foot orthoses on pain and function in individuals with patellofemoral pain syndrome: a cohort study.

The quadriceps is a group of four large muscles that sit on the anterior aspect of the thigh: Vastus Medialis, Intermedius, Lateralis and Rectus Femoris. Injuries to the quads are not uncommon for athletes in high-speed sports such as track or basketball (Brown, 2012), however, as common as these sprains are, they are treatable. According to Brown, a strained quad implicates a partial or complete tear of the one of the four muscles or their tendons when they're stretched beyond their normal limits
Osgood-Schlatter disease (OSD), a condition that affects preadolescent children, was first described concurrently by Robert Osgood, a US orthopedic surgeon, and Carl Schlatter, a Swiss surgeon in 1903 (Cakmak). Defined as a separation of the tibial tubercle apophysitis from the proximal end of the tibia, OSD appears in girls between the ages of 8 to 14 and with boys 10 to 15 (Kaya). The incidence of OSD is believed to occur in 21% of adolescents who play sports while non-athletes report only 4.5%

The benefits of running are innumerable, however by many people, running is an overlooked form of exercise. In reality, running is a vastly superior form of exercise. Running’s numerous benefits includes improvement of brain function, strengthening of the
The Ankle Joint, otherwise known as the Talocrural Articulation, is a synovial hinge joint that connects the distal tibiofibular joint to the upper surface of the body of the talus. Owing its strength to the shape of the articulating bones as well as the ligaments and tendons attached to it, the ankle joint is relatively stable in the neutral position. Dorsiflexion and Plantarflexion are the motions that take place at the talocrural joint. The following muscles contribute to the dorsiflexion of
I. INTRODUCTION Ice hockey is a sport played on ice, often within the confines of a rink. The sport is played with two teams on skates who use sticks to shoot a puck at a net to score, only occurring when the puck gets past the goaltender. The game is played with usually five skaters on the ice, plus the goaltender. Three of these players are usually forwards, while two are defenders. This game moves at a fast pace where players are on the ice for usually 45 seconds at a time before a line change
In today’s sports world, athletes are pushing themselves to the limits to accomplish a sound victory for themselves or their team. But sometimes they succumb to pushing themselves too hard and get injured. They put them in a position where the only option they have is getting an injury. Lots of injuries happen to the leg of the athlete, but the knee is where the most damage is. Although it does not happen often, a knee dislocation is a serious injury. Being different than a patellar dislocation which
-Medial collateral ligament (MCL) - Aids in stabilizing the knee towards valgus and varus forces of the knee joint. MCL originates above the joint line on the medial condyle of the femur and inserts below the joint line on the tibia. MCL also serves as a resist to external tibial rotation. MCL remains tight during knee extension and relaxed during flexion. - Injury may occur in MCL either as a result of a medially directed valgus force from the lateral side or it could occur from the external rotation
