The Benefits Of Key Training Physical Education Essay

Core is where our centre of gravity is located and where all activity begins. You can find 29 muscles that attach to the lumbo-pelvic-hip organic. An efficient center permits maintenance of the normal length-tension relationship of practical agonists and agonists, which promotes normal force-couple romantic relationships in the lumbo-pelvic-hip complex. Maintaining the standard length-tension associations and force-couple romance allows optimal arthrokinematics in the lumbo-pelvic-hip organic during functional kinetic chain moves (Prentice 4th edition "Rehabilitation Approaches for Sports Medicine and Athletic Training, 2004).

According to Stone et. al. (2006) on the journal "Weightlifting: a brief overview", weight lifting is a strength-power sport, where in fact the runners characteristics were very much like athletes from wrestling and hammer throw sport, in kind of the physical features (somatotype). Their level and weight ratio was typically lower than for most athletes. Although performance is partially related to body mass, better weightlifters will lift more in the snatch and clean and jerk. In the competition, weight lifted is partially related to body mass and tightly related to to peak electricity where smaller weightlifters have a higher maximum power and body mass ratio weighed against bigger weightlifters. Weightlifters are considered as the strongest and powerful among all athletics thus, their metabolic rate is known as high. The weightlifting training differs as it follows periodization program that cannot be generalized to other sport. But, the chance of injuries during training and competition aren't up to other sport.

Flexibility is the ability of the neuromuscular system to permit for efficient movement of an joint or group of joints through a full, nonrestricted, pain free range of motion. Most sport activities require relatively normal levels of versatility. However, some activities, such as gymnastics, ballet, diving, and karate, require increased in overall flexibility for superior performance. Proper weight training will probably increases dynamic versatility and, if combined with rigorous stretching program, can greatly boost powerful and coordinated moves that are essential for success in many athletic activities (Prentice 4th model "Rehabilitation Techniques for Sports Medicine and Athletic Training, 2004).

The core is commonly known as the "powerhouse" or the building blocks of all limb activity, because the core muscle is the center of the body and all limb movements or exercise will desire a support of the central. The center also absorbs the strain of any movement of your body, so that it is important to have a strong center muscles. Many methods cases to be successful in achieving in strengthening the core muscle and some individuals willing to invest whatever are needed to get a 6-pack. So the controversy is accessible to identifying the most effective's method to strengthen the main muscles (Lori AvedIisian et. al 2005).

The core muscles are the superficial and profound spinal extensors muscles, belly muscles, pelvic floor muscles, and shoulder girdle and hip girdle muscles. The word core strength identifies the strength of these core muscles. Core muscle durability is usually operationally described by a way of measuring of the effectiveness of central muscles, either in conditions of how much weight/resistance a muscle can lift up, how many repetitions a muscle is capable of doing, or how much time a muscle can take a neutral steady position. Specific spinal stabilization exercises have been proven to lessen future recurrences following an severe lower rear pain (LBP). Specific spine stabilization exercises or key exercise can achieved superior effects to isotonic exercises in chronic patients research by Craig Liebenson et. al (2007).

The advantages of core strengthening exercise or key stabilization are improving athletic performance, preventing injuries, alleviating low again pain, keeping proper torso stableness, postural control, and bettering appearance. Besides that, relating to Pierce et. al (2007), they state that the primary training is important to get ready the need runners that involve in activities such as running, climbing, swimming and so on. So to boost performance, they often coach and condition only the muscles used the most for the activities for example legs and arms, but not the core muscles. It could seem that each movement begins from the limbs, but actually the strength needed to perform any activities result from the key or the guts of the body. If they have strong core muscles and function as well as other muscle, any activities will be perform easily and take less work.

According to Roetert et. al. (2001) on their review, "Retention of Flexibility", being flexible provides benefits in training as well as in daily life activities. it can help in sports movement and invite for stresses accommodating. Furthermore, opposing muscle work can be lightened through less restricted action. Blood products also are more successful. Balancing becomes far better with enhancement of versatility. Besides sport setting, daily routine can be carried out in no stress, such as brisk walking, mopping, sweeping and so many more. In addition, flexibility can be maintained for a long term simply by doing sit and reach whereby it could be apply at home.

1. 1 Problem statement

Weightlifters that outperform were lack of core power and versatility as there was no keeping in training program basely on core muscles and flexibility. Because they grew older and achieve more impressive range in sport, the concentrate on maintaining core power and versatility is lowered. Therefore, they need to maintain their primary strength so that they can straight maintain their weightlifting performance.

1. 2 Goal of study

The main purpose of the study is to investigate the core strength and flexibility among Country wide weightlifters. This study is also seeking to show if weightlifters have good both primary strength and flexibility.

1. 3 Hypotheses

H0: You will see no significant correlation between age group and core durability and flexibility.

H1: You will see a significant correlation between generation and core strength and flexibility.

H0: There will be no significant correlation between BMI group and core strength and flexibility.

H2: There will be a significant relationship between BMI group and center strength and flexibility.

H0: You will see no significant relationship between core durability and overall flexibility.

H3: There will be a significant correlation between core durability and versatility.

1. 4 Objectives of the study

In this study, the objectives to be achieved are:

To determine key strength in weightlifters.

To determine versatility in weightlifters.

To determine whether weightlifters have center strength and flexibility at exactly the same time.

1. 5 Relevance of the study

Finding of this review can disseminate the value of core durability and flexibility especially for the weightlifters. In addition, it may suggest possible ways to enhance the players sport performance via various flexibility and core power program. The coaches can gain knowledge about the core power and flexibility of their athletes' specifically about training program. Coaches can concentrate working out program especially on growing fundamental main and flexibility workout program that will help performance final result.

1. 6 Limitation

In executing experimental study, there will be limitations that may occur:

The commitment of things. All subjects that have been preferred in this study were asked to participate in every test. A few of them were without their acknowledgment as only the coaches were informed about the experiment prior to the researcher presence. So, this may affect the consequence of the test as some of the weightlifters weren't ready.

The time constraints also can be one of the limitations because the content have their own training schedules and may not attend the test.

The subjects engaged were the weightlifters under Country wide Sport Council (MSN) guidance. Therefore, the determination of the subject matter cannot be completely gained. A lot of the subjects were busy using their training and other program

Lack of assistant also the limitation of the analysis. There have been only two individuals to help performing the experiment. Therefore, lack of manpower to provide support and demonstrating in gathering result.

Difficulties to comprehend the test technique becomes the limitation upon this test.

Maturity of the subject matter also could be the limitation of the study. Their awareness of importance of the test to researcher was lack; therefore, a few of them did not perform to their maximum level through the tests.

1. 7 Delimitation

Delimitations determine the generalizability of the study. This review was centering at feminine weightlifters aged 19-24 yrs. old core strength and flexibility. They were also elite sports athletes that play for condition and national level which were currently active. These things were clear of any accident especially lower backside pain injury. This is to ensure the assessments were done unbiased. Futhermore, the analysis was conducted in a single day assessment at Country wide Sport Council (MSN) Bukit Jalil gymnasium. The testing which used to measure the core power and flexibility which were &-level sit up and Sit down and Reach test were applied to every one of the subjects. So, the data gained were come from the same lab tests that could not create bias when the data is analyzed.


In this review, it presumed that all the subjects are able to complete the duty with no problem and hesitation from the instructions given. The analysis instrumentation was designed and choose as regards to the target populace account. Therefore, the lab tests tools are chose consequently to high consistency and validity of research hypothesis.

The researcher also assumes that this analysis will be utilized by the content and their instructor to gain knowledge about how to measure key strength and versatility. The info and results of the study are important to coach to learn the weaknesses with their sportsmen so that the situation can be fixed with some training and research.

The subjects are anticipated to give full dedication when accomplishing the tests. In addition, it assume that from this research study, the data accumulated and analyzes results will help in measuring center strength and overall flexibility as well as the relationship of these parameters.

Definition of terms

Core muscles

The "core musculature" can be defined generally as the 29 pairs of muscles that support the lumbar-pelvic-hip complex in order to stabilize the backbone, pelvis, and kinetic chain during functional motions. The key is also commonly referred to as the "powerhouse" or the building blocks of all limb motion (Faries et. al, 2007).


Flexibility is generally defined as the range of motion of the joint or series of joints that are affected by muscles, tendons, ligaments, bones, and bony constructions. Relating to Nelson et. al. (2005).


Weightlifting is strength-power sport in which two lifts are contested the two lifts, in order of execution in a contest, are the snatch and the clean (Pierce et. al, 2006).


Strength can be defined as the ability to produce force, and this power can be isometric or vibrant (Pierce et. al, 2006).


Power production is the product of power and velocity (F x V) and is probable the most important factor in determining success in most sports, specifically weightlifting (Pierce et. al, 2006).

Core training

Core training can be defined as training designed specifically to address a primary muscle or muscle action, whether performed independently or coactively to make a stable spine and torso. Key muscles include the musculature of the stomach and low-back regions (Stephenson et. al, 2004).
