Abstract

Six university soccer players were selected for a correlational and comparative study. The correlation between squat jump height and 10-metre sprints, 30-metre sprints, arrowhead agility test, static balance test and velocity ofball during instep kickwereinvestigated. The comparative study involved comparisons between ball velocityandbetween the muscle activity of vastus lateralis, rectus femoris, biceps femoris and tibialis anterior of kicking limb and supporting limbduring instep soccer kick from 0-degree, 45-degree and 60-degree angle ofapproachfrom the target with the dominant limb and non-dominant limb. A significant association was found between squat jump height and 10-metre sprints (r =-0.93, p = 0.007) and 30-metre sprints (r =-0.88, p = 0.021). Also, significantly greater ball velocities were attained from 45-degree angle of approach with the dominant limb(= 7.49, p = 0.010, partial 37.50, p = 0.002, partial = 0.88). Greater muscle activity was found in tibialis anterior of kicking limb(= = 0.60)as well as non-dominant limb(= 6.52, p = 0.015, partial = 0.57) when the dominant limbwas used for instep kick and in rectus femoris of supporting limb(= 5.536, p = 0.024, partial = 0.52) when non-dominant limbwas used from 0-degree approach.

Electromyography Comparisons of Lower Extremity Muscles during Maximum Velocity Instep Soccer Kicks

“…As a part of the warm-up, the subjects performed five minutes of dynamic stretching (Scurr et al, 2011) followed by a few short sprints. Rectus femoris (RF), vastus lateralis (VL), biceps femoris (BF), and tibialis anterior (TA) of both the kicking leg and supporting leg (Thapa et al, 2019) were selected for the electromyography study. The SENIAM (Surface Electromyography for Non-Invasive Assessment of Muscle) group's recommendations were followed for the procedure of electrode placement in the muscles.…”

“…the kicking leg and compared the muscle activation pattern in professional and amateur players, while Thapa, Kumar, Sharma, Rawat, and Narvariya, (2019) studied the muscle activation of four lower limb muscles of both kicking limb and supporting limb when kicked from different approach angles. All these studies were reviewed by the authors of the present paper and resulted in the conclusion that most of the studies conducted in EMG used muscles of the kicking limb, and that studies that included muscles of supporting leg did not report the contribution of ankle muscles (tibialis anterior) of the supporting limb.…”

“…In this study, 33 male university soccer players who were right-foot dominant were included (age 21.2±2.3 years, height 171.9±7.8 cm and body mass 66.2±6.9 kg). Limb dominance was selected by asking the subjects about which foot they would prefer to kick the ball for maximum velocity (Thapa et al, 2019). The subjects had a minimum playing experience of six or more years during the collection of data.…”

Effects of Six-Week Pre-Season Complex Contrast Training Intervention on Male Soccer Players’ Athletic Performance

“…Indeed, the observation of such demands during training sessions may predict match outcomes [4]. These maximal to near-maximal efforts are positively associated with the strength/ power of lower limbs [5,6,7,8].…”

Can complex contrast training interventions improve aerobic endurance, maximal strength, and repeated sprint ability in soccer players? A systematic review and meta-analysis

“…In addition to aerobic endurance, short-duration maximal-and near-maximal physical efforts (e.g., vertical jumps) are prevalent in soccer, and are required to overcome opponents during play (Stølen et al, 2005). These maximal-or near-maximal efforts have shown to be positively associated with the strength of lower limbs (e.g., maximal squat strength) (Arnason et al, 2004;Requena et al, 2009;Thapa et al, 2019;Wisløff et al, 2004). Moreover, maximal strength of lower limbs (e.g., one repetition maximum [1RM]) may also be used to differentiate the player's playing level (e.g., professional versus amateur) (Cometti et al, 2001).…”
