(PDF) Effects on plyometric training on jumping performance in junior basketball players Twenty-four highly physically active physical education students were randomly assigned either to a plyometric PLY group or a control group. The experimental group performed plyometric exercises 2 times a week for 6 weeks, whereas the control group participated only in their lectures.
Discover the world's research The purpose of this study was to compare the effects of 3 different training protocols-plyometric training, weight training, and their combination on the vertical jump performance, anaerobic power and muscular strength. Based on their training, forty-eight male college students were divided into 4 groups:

First, that plyometric training directly increases muscle size, and that bigger muscle size results in greater muscle power.
The Effect of Plyometric Training on Athletic Performance | Essay Example Urs Granacher Introduction To date, several meta-analyses clearly demonstrated that resistance and plyometric training are effective to improve physical fitness in children and adolescents. However, a methodological limitation of meta-analyses is that they synthesize results from different studies and hence ignore important differences across studies i.

Abstract Plyometric training PT is a technique used to increase strength and explosiveness.

To evaluate the effects of plyometric training on muscle-activation strategies and performance of the lower extremity during jumping exercises.

A pretest and posttest control group design was used. Experimental subjects performed plyometric exercises 2 times per week for 6 weeks. We used surface electromyography to assess preparatory and reactive activity of the vastus medialis and vastus lateralis, medial and lateral hamstrings, and hip abductors and adductors.

A Tukey honestly significant difference post hoc analysis revealed significant increases in preparatory adductor area, mean, and peak for experimental group. Pearson correlation coefficients revealed significant between-groups adaptations in muscle activity patterns pretest to posttest.

Effects of Plyometric Training on Muscle-Activation Strategies and Performance in Female Athletes

Although not significant, experimental and control subjects had average increases of 5. The increased preparatory adductor activity and abductor-to-adductor coactivation represent preprogrammed motor strategies learned during the plyometric training.

These data strongly support the role of hip-musculature activation strategies for dynamic restraint and control of lower extremity alignment at ground contact. Plyometric exercises should be incorporated into the training regimens of female athletes and may reduce the risk of injury by enhancing functional joint stability in the lower extremity.

The dynamic restraint system relies on feed-forward and feedback motor control to anticipate and react to joint movements or loads. The feedback motor- control process encompasses a number of reflexive pathways that continuously modify muscle activity to accommodate unanticipated events. Plyometric exercises are defined as eccentric loading immediately followed by a concentric contraction.

The series and parallel connective-tissue components of muscle also store elastic energy, which can generate additional force if a muscle recoils quickly in the form of a concentric contraction. Lastly, Golgi tendon organs usually have a protective function against excessive tensile loads in the muscle; however, after plyometric training, Golgi tendon organ desensitization is thought to occur, 21 allowing the elastic components of muscles to undergo greater stretch.

When the stretch reflex and stored elastic energy are combined, a more powerful concentric force is created. For this reason, plyometric training may enhance neuromuscular function and prevent knee injuries by increasing dynamic stability.

Furthermore, Hewett et al 23 indicated that females who participated in a plyometric training program had a significant decrease in the number of serious knee injuries. Neuromuscular adaptations are believed to enhance dynamic knee stability and performance 22 ; however, the specific adaptations responsible for the success of plyometric training are still theoretic.

Our purpose was to examine the effects of plyometric training on muscle-activation strategies and performance in female athletes during jumping activities. The independent variables were time pretraining, posttraining and training group control, plyometrics.

The dependent variables were electromyography EMG signals area, mean, peak, coactivation, pattern and our performance measures for the thigh musculature vertical jump height and sprint speed. Subjects Twenty National Collegiate Athletic Association Division I collegiate female soccer and field hockey players, 18 to 22 years of age, volunteered to participate in the study.

Exclusionary criteria included any lower extremity reconstructive surgery in the past 2 years or unresolved musculoskeletal disorders that prohibited subjects from sport participation.

All subjects participated in off-season training that involved practice 3 times per week and weight training 2 times per week. Random assignment was performed, and subjects were placed in either the control group 9 subjects: The mean height for the control group was The mean weight for the control group was Any subject who missed more than 1 training session was removed from the study.

All control subjects were asked to refrain from any plyometric-type training. After pretesting, 1 control subject was removed from the study because of an unrelated surgical procedure.

One experimental subject was removed from the study after posttesting because of error in EMG calibration.Plyometric and resistance exercise trainings contribute to athletes’ power and speed. The present study aims to compare the effects of plyometric and resistance exercise trainings on crural explosive power and speed in young female Taekwondo players.

A number of 20 Taekwondo players (Age=± yrs). Effects of Plyometric Trainings. Topics: Muscle, THE EFFECTS OF A 6-WEEK PLYOMETRIC TRAINING ABSTRACT The purpose of the study was to determine if six weeks of plyometric training can improve an athlete’s agility.

Subjects were divided into two groups, a plyometric training and a . The plyometric training group performed in a six week plyometric training program and the control group did not perform any plyometric training techniques.

All subjects participated in two agility tests: T-test and Illinois Agility Test, and a force plate test for ground reaction times both pre and post testing.

Abstract. The purpose of this study was to compare the effects of 3 different training protocols-plyometric training, weight training, and their combination on the vertical jump performance.
