The Effect Of Plyometric Exercises On The Body 's Power And Force Output Essay

Oxygen debt in the muscles is reached when oxygen levels are much lower than required during strenuous physical activity, causing lactate fermentation to occur in the cells leading to muscle fatigue. The results found in the experiment were the number of squeezes in the first trial for the dominant and non-dominant hands were significantly higher than the remaining ones. The results also showed as the trials continued, the number of muscle contractions decreased steadily which supported the hypothesis. However, there were some increased numbers for the dominant hand from trial 4 to 5 and trial 9 to 10. The non-dominant hand expressed similar unexpected results from trial 6 to 7 and trial 9 and 10. The reasons for these results might be due to the finger muscles being worked at the high intensity for a long period of time causing the muscles to consume higher amounts of oxygen thus producing more ATP production. This would cause the muscles to create more contractions towards the end of the trials. The unexpected results could also be caused by experimental errors such as faulty clothespins. The springs connecting the two ends of the clothespin was tight causing the number of contractions as the trials progressed having a more significant decrease. This is because the amount of energy required to open and close the clothespin would be higher, causing the lactate threshold to occur quicker. Due to this, the number of squeezes would decrease drastically as the trials progressed, in contrast to if the springs were normal. This would change the results by the difference between the trials not being evident therefore, not demonstrating the effects of muscle fatigue. Another factor that altered this experiment was the participant’s condition, Palmar Hyperhidrosis –excessive sweating on the palms – which

The definition of power training is training is most commonly used to develop a muscle group’s ability to contract at maximum force in the shortest amount of time possible (McArdle, Katch & Katch 2015). Weight training is defined as a system of conditioning involving lifting weights especially for strength and endurance (Merriam and Webster 2015). Power is important to acceleration as the runner’s feet are in contact with the floor for longer than if they were at full speed and so more power is needed to create movement and quickly (Mansfield athletics club 2012). Research, by Mohamed Souhaiel Chelly (2009), showed the effect of back squat and other forms of power training over a 2 months period (twice a week) on acceleration and other forms of explosive movements by football players. They found that in the first 5 meters in a 40m sprint the velocity of the players improved after using the power training techniques. This is specific to junior soccer players and so may not be specific to other sports or those of different athletic standards. In the book ‘strength and power in sport’, it is noted by the author (Latif Thomas 2010) that “The use of training methods involving, maximal and near maximal contractions, cause a remarkable increase in RFD accompanied by an

Next, the plyometric session, which is every two weeks, will now be weekly and stay as is by using the agility ladder but also include box jump exercises. Plyometric training is vital as it is essential for increasing power by the muscles having to exert maximum power in short intervals (PlyoCity,

In this assignment I will be reviewing the different effects of exercise on the body system including the acute and long term using the pre-exercise, exercise and post-exercise physiological data which I collected based on interval and continuous training method. I will also be including the advantages and disadvantages of these, also the participants’ strengths and areas where they can improve on.

Power is the rate at which work is performed. It has a speed component to it, unlike strength. The explosive aspect of strength is referred to as maximal muscular power and is the functional application of both strength and speed of movement (Kenney, Wilmore, & Costill, 2015). The Wingate Anaerobic Test (WAnt) has been proven to be a tool that is reliable for assessing muscular power, endurance and fatigue. A study was completed in order to determine the relationship between upper body strength and power and on the upper body anaerobicperformance. A bench press and bench press throw was used to determine upper body anaerobic performance and was measured during an arm ergometry WAnt (Lovell, Mason, Eagles, Shewring &Mclellan,2011).

According to Sleeper, Kenyon, & Casey (2012), for gymnasts core training is very important. Gymnastics is a sport that engages the muscles of the entire upper and lower body. Along with training the rectus abdominis, transverse abdominis, and inner and outer obliques, strengthening the core involves the stabilization of the pelvis (mid body), the shoulder girdle (upper body), as well as the spine (upper-mid/lower body). Bodyweight exercises are the main type of training modality used by gymnasts to prepare for competitions (Behm, & Colado, 2012). Plyometrics are beneficial for gymnasts because these dynamic and explosive movements allow the athlete to increase strength and speed which are both necessary in order to

The inconclusive data of these results is most likely due to the variability of each individual's muscle strength and endurance. If muscle fatigue had been further increased then the results may have provided more conclusive data and less error. As a result of individual muscle endurance and strength, the muscle performance of the majority of the group was not affected by

To test the muscle strengths the subjects were required to use the one repetition maximum method for a variety of different exercises. The experiment consisted of the subjects rising from the chair without the use of their hands. During the trial reflective markers were

Plyometrics are all about trying to produce the maximum force available in the quickest time possible. So they are not about overall strength or overall speed, but the best combination of the two. People talk about this in terms of "power".

In Noyes and Barber-Westin’s study (2015), they developed a neuromuscular retraining program that proved effective in decreasing ACL injury rate in female athletes. This program included a dynamic warm up, a jump/plyometric component and a flexibility component (cite). The purpose of a plyometric component was to teach and emphasize proper jumping and landing techniques. There were 1000 trained female athletes aged 13-18 years old included in the study and the noncontact ACL injury rate of 700 of these athletes was compared to 1120 control athletes to provide

We found that the muscle strength of trunk flexion showed significant differences within group and between groups. The results of the trunk back extension showed significant differences within group. Our result of increased trunk strength was similar to previous study results. Within group difference of muscle activation was higher in the BLSE group than in the HLSE group. This implies that the EO and RA were activated as the agonist of trunk flexion, and that muscle hypertrophy can increase strength of trunk flexion when activated by the EO and RA. One study showed EO activated approximately 32% of MVIC by bracing and 12% of MVIC by hollowing (Grenier & McGill, 2007). The % EMG max values in RA was 18% in the bracing strategy, while the RA value was approximately 6% in the hollowing strategy(Maeo et al., 2013). Thus, we suggest that trunk flexion strength would be increased by muscle hypertrophy if the bracing strategy is applied in side plank exercise and prone plank exercises, which activate EO and RA, for 12 weeks.

Plyometric training can be referred to as as a powerful quick movement that involves an eccentric contraction, that is followed immediately by an explosive concentric contraction. This is achieved through the stretch-shortening cycle, also known as the eccentric-concentric coupling phase or integrated performance paradigm (Chimera, Swanik, Swanik, & Straub, 2004). This phase suggests that in order to move with accuracy, forces must be loaded (eccentrically), stabilized (isometrically), and then unloaded (concentrically). Thus, plyometric exercise activates the body’s proprioceptive and elastic properties to produce maximum force output in a minimum amount of time (Voight & Brady, 1992).
