Plyometric Training
Plyometric training is a form of training that is used to help develop and enhance explosive power, which is a vital component in a number of athletic performances. This training method is meant to be used with other power development methods in a complete training program to improve the relationship between maximum strength and explosive power (Radcliffe 1). In order to understand how plyometric training works or why it is so effective, one must understand what is meant by "power." Power is similar to strength but with the time factor included, meaning speed. So power is relationship between strength and speed and deals with the ability to perform a certain activity or movement the fastest (Gambetta).
Most explosive movements do not take that long. Therefore the importance is placed on the ability to generate the highest possible force in the shortest period of time, and at the same time, reducing or stopping this force at the end of the action (Gambetta). Even though it is not fully understood how plyometric training actually works, it is believed that the basic principle which is behind it is based on the idea of the rapid "stretch reflex." This stretch reflex is the result from the rapid loading (stretching) and unloading (unstretching) of the same muscle fibers. An example of the stretch reflex is when a right-handed golfer begins his/her back-swing. In performing this movement, the bicep muscle of his/her left arm contracts while the tricep muscle in the same arm is stretched. Then when the forward-swing is begun, the tricep contracts in response to its rapid stretching which triggered the stretch reflex (Radcliffe 8). In Plyometrics, training enhances the tolerance of the muscle for increa...

In lab, isometric handgrip strength was tested. Isometric strength refers to the type of force that occurs when muscles generate force, but its length remains unchanged. This can also be called a static muscle contraction. A static contraction occurs when one tries to lift an object that happens to be heavier than the force applied to the muscle or a static contraction occurs when one supports the weight of an object by holding the object steady with the elbow flexed. In both of these examples, the person feels their muscles tense but the joint does not move (Kenney, Wilmore, & Costill, 2012). Handgrip strength reflects the importance for successful performance in activities of daily living and occupational activities (Beam &
For years it was thought that the golf swing was a solid piece of movement without any differentiating variables. Vast expansion in technology over the last 20 years has produced more information on the biomechanics of the golf swing. “ Golf Biomechanics applies the principles and technique of golf mechanics to the structure and function of the golfer in an effort to improve the golf technique and performance” (Hume P., Keogh J., and Reid D. 2005) Biomechanics, “The scientific discipline that applies mechanical principles and to understanding movement.” (Hume P., Keogh J., and Reid D. 2005) allows scientists to observe a golfer’s swing to near milliseconds to the point of impact. This is much more precise to previous measurements used such as video recordings, outlines, etc. Understanding how the swing works by breaking down the movements within the swing through visual aids emphasize the opportunity for a better swing and in turn, better golf. Studies of biomechanics within the golf swing have shown the sequential separation from torso to pelvis, disproving the original theory of a solid swing with continuous motion known as the X-factor. Before understanding how the biomechanics of the golf swing works with the X-factor, the basics of the swing must be established.
There are different types of muscle because each sport has various needs. “Power endurance is typically characterized by intense, repeated efforts for a relatively short period of time (less than 30 seconds)”(1). Sports such as sprinters, wrestlers, fencers and tennis players need to produce powerful movements and repeat them with several times with little to no rest. This training involves lifting about 15-30 reputations of moderate loads, about 50%-70% 1RM per lift.

The wrist flexors during this deceleration phase become concentric. The timing of this muscle’s change in purpose and action places the most emphasis on accuracy beyond the arrangement of the hips and shoulders. When discussing the biomechanical factor’s influencing the ball’s trajectory, Macagnone (2016) states, “This phase will vary based on the shot technique performed and player skill level …” This statement emphasizes the diversity in accuracy based on personnel and the skill level. To maximize accuracy when taking a lacrosse shot, the timing of the wrist flexor’s change in motion determines the trajectory of the ball. The trunk plays a major role in accuracy as well because of its support for the upper extremities during ball release and the influence of momentum and force of the ball’s

The world of sports and athletics has become inundated with ways to get fit, trim fat and build muscle. The truth be told there are no quick fixes or workout plans that work the exact same for everyone. Many factors play into the effectiveness of a successful workout program. There are just as many techniques of working out as there are factors to success. Finding which workout technics work for each athlete or client can be the difference between mediocre progress and phenomenal progress. A few of the workout technics that stand out amongst the pack are Forced Repetitions, Periodization (cycling), Pyramid System and last but certainly not lest Super Sets. The afore mentioned techniques span beyond the basic iron pumping mentality of weight training and narrows the scope of training down to a more scientific application. For the purpose of this research a more in-depth look will be taken into each technique and then further identify any similarities and or contrasts.
Athletic training has evolved into a major influence in athletes’ lives. Growth of the athletic trainer’s role from ancient times to present has been on a tremendous rise of new and better equipment also well-educated individuals to prevent and help athletes when needed. Athletic training has evolved as a major paramedical profession since the 1950, when the National Athletic Trainers’ Association (NATA) was formed. The primary purpose for its formation was to establish professional standards for the athletic trainers.
To achieve a degree in Athletic Training, there are many tasks and skills to be learned. The Education Council under the National Athletic Training Association put together an education program filled with a set of guidelines of what has to be taught to graduate with a degree in Athletic Training. Before you can learn and understand Athletic Training, you must know the Anatomy and Physiology of the human body. This includes bones, muscles, levels of organization, tissue levels, systems of the body, skeletal structure, articulations, integrative functions, sensory function, blood, and embryology (Martini, 2001). Besides Anatomy and Physiology, the methods of taping is also extremely critical to this career. Before you can understand what each taping techniques are used for, you must also know about sports injuries. Athletic Training is all about the prevention, treatment, rehabilitation, and evaluation of athletic injuries. Another skill that must be learned in the Athletic Training Education Program is how to provide immediate emergency care. That includes everything from background information to actually being able to save an athlete’s or any one else’s life. You must be aware of legal considerations, how and when to approach a victim, the human body systems, examining the victim, basic life support, bleeding and shock, identifying wounds, sudden illnesses, injuries, and how to care for them; also you must be aware of cold and heat related injuries, and how to rescue and move victims (Thygerson, 2001). Other information to be learned includes nutrition, health, and professional development. There are several other topics of Athletic Training; however, there are just to many to s...
Imagine the inability to physically walk or do so pain free, or to sit, or do any type of daily routine without any sort of constant complications. Whether a person has been injured, born with a disability condition, or a disability occurred due to aging, there is a way to help treat many complications. Participating in a physical therapy rehabilitation program can help to heal an injury by proper, safe exercises to strengthen and prevent further injury or by teaching one to change their mechanics, which in turn will create a better way to manage daily routines safely and pro actively. Physical therapy can also help to prevent or decrease impairments such as the developmental affect of many genetic diseases, congenial disabilities or disabilities due to aging. Physical therapy is a rehabilitation program with the goal to assist in the recovery of surgeries and injuries, and to promote proper mechanics and motor functions; relieving pain and restoring and maintaining physical mobility, strength and a quality of life.
