It was first introduced in Olympics and it became more prominent to all athletes most especially to those who use jumping as their main source of power. There are such things that can help to improve high jumps and good balance of hopping. And this would help using plyometric trainings and drills. While doing this training some part of leg muscles are getting firm and stronger. Those are quadriceps hamstrings and calf.
While some programs help improve general fitness or prepares the body for a specific sport, plyometrics aims to give an athlete an extra physical edge in the sport of their choice through high intensity bursts of movement (Boone, 2010). This is because plyometrics conditions the body to produce fast, powerful, and explosive movements. As a training program, it utilizes a series of stretches, muscle-contracting drills, and rapid exercises that are focused on a specific part of the body that is vital to performance in a specific sport.Plyometrics develops speed and strength, but not in the same way as weight-training or strength-building does. Instead of focusing on having bigger muscles and conditioning for raw physical strength, plyometrics aims at making muscles that work better and more efficiently in order to build strength and speed (Boone, 2010). This, mixed with the dynamic, quick bursts of movement is what separates plyometrics from weight-training and strength-building.
On this study, they used force plate to trace the center of pressure (CoP). For the first task, those gymnasts required to sit as still as possible on the hemisphere for 30 seconds. While the second task required the gymnasts to lean back on the seat over a set angle and suddenly released in which the subject had to regain balance. The result was recorded before and after the research. As the discussion, the writers stated that training activities will affect the trunk
Introduction: Gymnastic can be a scary sport and that is why in order to be successful, athlets have to be able to deal with isuses such as outside distraction, fear and anxiety, in an effective way. Those are pretty much everyday issues for a gymnast and controling them is a important task especially since there is a potential risk in overcoming the athlete`s levels of self-confidence, motivation and performance. The gymnastic coach task is not only to provide the gymnasts with the physical tools necessary for succes ,but also the mental tools that helps the athletes to handle both the cognitive and emotional challenges characteristic in competitive gymnastics. Mental imagery is one such tool which, if used properly, can positively affect skill development, arousal, motivation, and confidence (Gliksky, et al., 1996; Jones, et al., 2002; Nicholls, et al., 2005). The theme of the essay is “Visualization in artistic gymnastics”, focusing on the importance of mental practice in helping the gymnasts with improving their performance and/or overcoming fear in balance beam.
During the familiarization session, subjects had their height and weight taken, completed a Physical Activity Readiness Questionnaire (PAR-Q) and survey crafted by the testers. The two tests chosen for upper body push and pull strength ratio are timed push-up and timed modified pull-up. The two tests were done on different days with at least one day in between to prevent delayed onset muscle soreness from affecting their ability in performing the tests. Two tests of upper body strength were performed by a group of healthy recreationally active males. 1.
Before we started the endurance test, I had my client do some jumping-jacks and a few stretches to prepare his body for exercise. For my client’s upper body endurance test, he did a 1-minute push-up test. My client told me after he done this test that his back was hurting during the test, so I made him rest for about 5 to 10 minutes. He also did a 1-minute sit-up test for his core endurance. He did not complain about his back hurting during this test.
The most common of these is dynamic unbalance. BALANCING: Balancing is defined as the process of designing (or modifying) a machine in which unbalanced forces is minimum. Balancing is the technique to correct or eliminate unwanted inertia forces or moments in rotating reciprocating masses and is accomplished by changing the area of the mass centers, so that it rotates in its bearings without unbalanced centrifugal forces. Engine balancing objectives are to ensure: • the centre of gravity of the system remains stationary throughout a full revolution of the crank shaft and • the couples associated in acceleration of the various moving parts balance each other. In rotor or reciprocating machines, numerous a circumstances unbalance of forces is formed due to inertia forces related with the moving masses.
Height was measured using a stadiometer; body mass, muscle mass, fat mass and body mass index (BMI) were determined using a Tanita Body Composition Analyser BF-350. Each player completed questionnaires regarding age, years of experience as well as injury history. Vertical jump was also measured using the stadiometer, to get an estimate of each player’s lower body strength. To determine the vertical jump, each player held a marker in line with his fingers and a dot was placed at two points; the maximum arm stretch of the player while his feet were flat on the ground and the maximum arm stretch of the player when he jumped. The vertical jump measurement was determined as the difference between these two points combined with their mass.
The common test used is “Sit and Reach” Equipment: • Measuring tape • Floor Matt Procedure: • On the matt the tape is stick • Participant must sit in a V-Position and bend in front and touch the hand on tape. • Then it is marked till where he can stretch and reach. PSYCHOLOGICAL TESTS Psychological tests are important to have an idea about the athletes own psychology that his attitude towards the life, game or self . intelligence, maturity and other prospectus that can affect athletes performance need to be monitored like some peer pressure , family problems etc. there are various test that can be performed like: Ruler drop test: From this a persons attention his reaction time to anything can be tested.
