Most of the investigations at this overhead smash may find difficulty in finding the initial velocity (after impact) of a shuttlecock. In this study, the flight performance of three shuttlecock models namely Feather Yonex, Nylon Mizuho, and Nylon Gozen was investigated during overhead smash. Additional comparison between standing and jumping smashes was also investigated. Corrected initial velocity by using regression equation method was performed and the reduction of velocity at certain distances was investigated. The record of racquet swing and shuttlecock flight after impact from high speed camera were observed. The shuttlecock release point was drawn in the X-Y coordinate in a linear form. The equation for the racquet swing was Y = a1 X + b1 and the path for shuttlecock was (Y = a2.X + b2). It was found that Nylon Mizuno had the lowest initial velocity, while Feather Yoned and Nylon Gozen had similar value. After traveling for 5 meters, the velocity of both standing and jumping smashes reduced into 30-40% of the initial velocity. Furthermore, the investigation between standing and jumping smashes showed that the initial velocity of jumping is higher than that of standing smash. Thus, jumping smash can be considered as the main weapon when playing badminton.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Badminton,Initial velocity,Overhead smash,Regression,Shuttlecock[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
