Muscular Force. The abdominal muscles, quadriceps, hamstrings, and calf muscles all work together to produce a muscular force to help move the athlete when backhanding a ground ball. These muscles help the athlete accelerate and decelerate to change direction into the drive step. This force is necessary to thrust the body into the throw and provide more power behind the throw. The rate of acceleration increases with more force produced. Levers. There are several levers in the body that help the athlete field a backhand. These levers found in the body can be classified in three categories, are used to overcome resistance, and rotate on a fixed point. Hip flexion is exhibited during the drive step phase and is slassified as a 2nd class lever. The resistance point of the hip occurs when the athlete must transfer weight from the left to the right side of the body, from prepatory step to drive step. This resistance occurs as the hip’s axis, the joint of the hip, bends. Another point in the body that can be classified as a lever is the knee. Flexion occurs in the drive step phase when fielding the backhand, which classifies the knee as a 3rd class lever. As flexion occurs the knee joint bends and provides an axis for the lever. Force is produced in proximal head of the tibia and fibula toward the origin of the hamstrings, as the shin provides a resistance point. Both of the levers are used to transfer weight into a throw and overcome resistant forces. Torque. …show more content…
Torque plays an important role in providing power behind the athlete’s throw when fielding a backhand. The knee, along with the rotation of the trunk produces torque as the athlete moves from the prepatory step to drive step. It is defined as the amount of force placed on an object. To calculate this, the mass of the model must be multiplied by the angular acceleration. This can increase with the greater distance of the momentum arm. The higher the amount of torque the more power produced behind the

Greig's Muscle Strain Injuries In Soccer

studies of Hawkins and others (2001) it seemed that 41% of all injuries recorded in soccer where identified as muscle strain injuries, most commonly to the thigh region i.e. hamstring, quadriceps and adductor injuries (Hawkins et al. 2001). Further research by Greig (2008) highlighted that these muscle strains occurred in the later stages of playing time in a soccer match. So Greig (2008) realised that there must be a significant reason to why English soccer league players pick up injuries at similar…

Essay about Brain Computer Interface

(Rouse, 2011). Once BCI computer chips are surgically implanted into the brain, their objective is to translate signals from brain neurons into physical activity. Unlike other human–computer interfaces, which require muscle input, BCIs provide “non-muscular” communication, allowing individuals with limited physical capabilities to carry out certain activities using only their thoughts (Graimann, 2010). In order to operate flawlessly, a BCI has to follow three simple steps. Primarily, it must record…
