IRCT | The comparison between effect of adding external and internal focus to plyometric training on agility, lower extremity landing mechanic, performance, balance, strength in subjects with neuromuscular leg dominance deficit.

Protocol summary

Study aim: The goal of this research, The comparison between effect of adding external and internal focus to plyometric training on agility, lower extremity landing mechanic, performance, balance, strength in subjects with neuromuscular leg dominance deficit.
Design: this research, because of two intervention group and one control group is quasi- experimental and clinical trial and research designe is pre and post test, a blinded study and randomize control trial. 54 participants will be recruited and loss of participants will be 20%.
Settings and conduct: In this research, participants are selected by tuck jump assessment and we will do pre test and execute the training phase. Finally, post test phase will be performed. It is noteworthy that training and test phases will be implemented at Omid gym in Takab city.
Participants/Inclusion and exclusion criteria: . Men and Women in 12 to 18 years old range; participants with normal BMI; Participants recruited for this thesis must haven’t any previous injury, surgery in lower extremities, and cardiovascular disease.
Intervention groups: In this thesis, there are two intervention group. first experiment group will do plyometric training with external focus and second experiment group will do plyometric training with internal focus.
Main outcome variables: performance, Balance, Strength, Agility ,and Lower extremity Landing mechanic

Sample size

Target sample size: 54

Randomization (investigator's opinion)

Randomized

Randomization description

In this study, researcher initially select 54 sample sizes and then, randomly divided them into 3 groups include: control group (n=18), first experimental group (n=18) ,and second experimental group (n=18). for randomization assignment coding boxes with random order will bee used that their size and forms are similar. thus. thay consist of numbers from 1 to 54 . this proses is so that number 1 to 18 will bee assigned to first experimental group, number 19 to 36 will bee assigned to second experimental group ,and number 37 to 54 will bee assigned to control group.

Blinding (investigator's opinion)

Single blinded

Blinding description

In this research, participants will be divided into two experimental groups and a control group. At first, They will be informed about research process generally But, They will not informed about research details such as; objectives. In exert phases, the first and second intervention group will be separated then others. Data analysis will be implemented by statical data analysis specialist so that he/she will be received statistical data.

Intervention groups

1

Description: Intervention group: the first intervention group: in this group, participants will execute plyometric training with external focus for 8 weeks (30 minutes). Training phases will be started easy training levels (such as ;bilateral squat jump in place, forward) and will be advanced step by step (such as; unilateral squat jump, unilateral countermovement jump and execution by rope and medicine ball). participants will be exerted squat jump and trainer will be asked them that knees and feet are parallel to embedded cones during landing and knees are bend to cones as high as.
Category: Prevention

Description: Intervention group: The Second intervention group: in this group, participants will execute plyometric training with internal focus for 8 weeks (30 minutes). Training phases will be started easy training levels (such as ;bilateral squat jump in place, forward) and will be advanced step by step (such as; unilateral squat jump, unilateral countermovement jump and execution by rope and medicine ball). An example for internal focus with squat jump; An example for internal focus with plyometric; participants will be exerted squat jump and trainer will be asked them that knees and feet are parallel, knees aren’t valgus position in landing.
