Developmental differences of kinematic and muscular activation patterns in instep soccer kick

Abstract

Kinematic and neuromuscular activity differences amongst soccer players in different age groups were examined in this study. Thirty male soccer players evenly divided into three age groups (Group 1: age 12-13; Group 2: age 14-15; Group 3: age 16-17) were asked to perform instep kicks towards a target 11 m away. Their anthropometrics, instep kick kinematics, resultant ball velocities, both legs isokinetic strength, and electromyography (EMG) during kicking were compared amongst the three age groups. There were significant differences in height, body mass, body mass index, ball velocities, and isokinetic strength values amongst three age groups. Also, kicking kinematics including angular and linear velocities of hip, knee, ankle, and toe were significantly different (p < 0.05) amongst groups in several kicking phases. Furthermore, the activities of m. rectus femoris, m. vastus medialis, m. biceps femoris were significantly different amongst groups (p < 0.05). The ball velocities and leg strength parameters increased with age, neuromuscular activations, and kinematic parameters differed especially in legcoking and forward swing phase of instep soccer kick. It should be concluded that an increase of resultant ball velocity of the instep kick is closely associated with chronical age, the development of leg muscle strength, and the neuromuscular activity of the kicking leg.

The effects of proprioceptive exercise training on physical fitness and performance of soccer skills in young soccer players

“…In this study, long-pass performance improved with 8 weeks of proprioceptive exercise training. It is well-known that long-pass ability is generally strongly related to muscle strength ( Cerrah et al, 2024 ). However, the training group showed a significantly lower increase in muscle mass than the Cont group in this study; improved long-pass performance results suggest that long-pass performance by young soccer players is more closely related to accurate movement performance, for example, by stability of the stepping up foot than muscle strength.…”

“…anterior na perna de chute(LEES et al, 2010). Portanto, é recomendado que o CP seja combinado com a VB, VPC e a relação VB/VPC na bateria de testes durante o processo de ensino-aprendizagem-treinamento, e em estudos subsequentes, para todas as faixas (RODRÍGUEZ-LORENZO et al, 2018), Cerrah e colaboradores(CERRAH et al, 2020) e Kapidvzic e colaboradores (KAPID ŽI Ć; HUREMOVI Ć; BIBEROVIC, 2014) pode ser explicada pois a amostra do estudo de Vieira e colaboradores(VIEIRA et al, 2018) e a correlações fortes entre a VB e as variáveis CP e VPC no momento pós, além de correlações fortes entre a VB e a razão VB/VPC nos momentos pré e pós do GC. Já no GI, não foram encontradas correlações fortes entre a VB e as variáveis cinemáticas nos momentos pré e pós.…”
