Coordination Aspects of an Effective Sprint Start

Abstract

The aim of the present study was to examine differences in the movement structure and the coordination aspects expressed by bioelectrical tension indicators between a group of experts/sprinters and a group of novices/students. A group consisted of 20 sprinters and a control group consisted of 35 master’s physical education students. A 16-channel surface electromyography (14 muscles) and two cameras with recording speed of 250 frames/per second were used. Significant differences were found between reaction time (p < 0.005) and time at 30 m of the covered sprinting distance (p < 0.001) between the students and advance athletes. Furthermore, the sprinters activated the back foot (taking off the starting blocks) and the front foot (first ground contact) earlier, which correlated with the attained times at 5 (r = 0.66) and 10 m (r = 0.62) of the covered sprinting distance. The most important component of the sprint start, apart from the muscle strength of the legs, is the appropriate motor coordination, which greatly affects the generation of power in the legs at the right time and optimal duration.

Association of phase angle and appendicular upper and lower body lean soft tissue with physical performance in young elite soccer players: a pilot study

“…Again, future studies including a larger sample of soccer players are warranted to better explore the association between PhA and running anaerobic performance over short (<20 m) distances. Although muscle power and strength remain the most important component of sprint performance, it might be argued that other elements (e.g., intra-and inter-muscular coordination, step frequency, and step length) 33 may also impact acceleration, especially during the sprint start 34 , which are apparently unlinked to PhA.…”

Pengaruh Power Otot Tungkai, Kecepatan Reaksi, Dan Koordinasi Mata Tangan Kaki Terhadap Kemampuan Lari 100 Meter

“…Hasil penelitian ini sesuai dengan penelitian (Borysiuk et al, 2018), bahwa komponen terpenting dari lari Sprint adalah Power otot tungkai, koordinasi motorik, yang sangat mempengaruhi pembangkitan tenaga di tungkai pada waktu yang tepat dan durasi yang optimal. Kecepatan lari seorang atlet dipengaruhi oleh Power otot tungkai.…”

The importance of reaction time to the starting signal on race results in elite motorcycle speedway racing

“…RT is considered a predictor of the cognitive system's ability to process information [13]. Previous research determined importance of RT in various sport disciplines [14,15], compared sex differences between athletes [16] and studied influence of training interventions on reduce RT [17] eg. auditory stimulus training [18].…”
