The effects of vertical versus horizontal based strength training on muscle activation, kinematic output and kinetic output and the relationships with the method of instructions given

This study was conducted to investigate the effectiveness of vertical versus horizontal based training training on muscle activation, output kinematics and output kinetics and their relationship to instructional delivery methods. Therefore, a total of 30 recreationally active male participants aged between 19-29 years old were recruited for the purpose of this study. In the first week all participants underwent pre-test as base line, then study participants were divided into verbal instruction group and video instruction group. All participants went through the phase of vertical and horizontal training based on training training based on the instruction method that has been set for 8 weeks. After that, a post-test was conducted. Mega Electronics Wireless Bioamplifier 16 channel EMG System by DELSYS TRIGNO has been used to measure muscle activation, 6 Axis force platform Model AMTI BP400600HF to measure output kinetics, and Vicon T10s are used to measure output kinematics. MANOVA was used to determine significant differences in muscle activation, kinematic output and kinetic output for both groups of instruction, verbal and video methods in pre-and post-test, One way ANCOVA was used to compare the effectiveness of strength training using the vertical ( lunges) and horizontal (squat) to the kinematic output, kinetic output and muscle activation between verbal and video instruction groups, and Correlation analysis method used in this study was Pearson product moment to look at the relationship between variables on lunges and squat activity for verbal instruction groups and video instruction group. An alpha level of 0.05 was used for statistical significance in all normally distributed data. The results of the study found that there was no significant difference for both groups in the pre test and post-test. Comparison between groups; for muscle activation only BF during lunges activity showed significant differences, kinematic output only ankle angle for lunges and squat, while kinetic output can be significant differences. As for the percentage of change, for the verbal activation of the verbal group is better than the video group, the kinematics of the output, both groups show significant permeability. In conclusion, the findings of this study indicate the role of instructional methods on muscle activation, output kinematics and output kinetics even with significantly less clarity. This is due to the possibility that the almost identical level of physical ability of the study participants produced such findings. For further study, manipulating the body mechanical among the participants, less focus on the smooth muscle among the participants, and the study of how muscle activation during the learning of a particular skill or movement.
