Amiri-Khorasani, M, Abu Osman, NA, and Yusof, A. Acute effect of static and dynamic stretching on hip dynamic range of motion during instep kicking in professional soccer players. J Strength Cond Res 25(6): 1647–1652, 2011—The purpose of this study was to examine the effects of static and dynamic stretching within a pre-exercise warm-up on hip dynamic range(More)
The purpose of this study was to examine the effects of static, dynamic, and the combination of static and dynamic stretching within a pre-exercise warm-up on the Illinois agility test (IAT) in soccer players. Nineteen professional soccer players (age = 22.5 ± 2.5 years, height = 1.79 ± 0.003 m, body mass = 74.8 ± 10.9 kg) were tested for agility(More)
AIM The purpose of this study was to compare the acute effects of different stretching methods on acceleration, speed, agility, power, and flexibility in different soccer positions. METHODS AND RESULTS Therefore, 16 soccer players conducted 10 m, 20 m, shuttle run agility, vertical jump, and V-sit flexibility after static (SS), dynamic (DS), combined(More)
This study investigated the number of trials necessary to obtain optimal biomechanical responses in 10 consecutive soccer instep kicks. The kicking motions of dominant legs were captured from 5 experienced and skilled adult male soccer players (height: 184.60 ± 4.49 cm; mass: 80 ± 4.24 kg; and age: 25.60 ± 1.14 years) using a 3D infrared high-speed camera(More)
The purpose of this study was to compare the effects of static and dynamic stretching on quadriceps muscle activation during maximal soccer instep kicking. The kicking motion of twelve male college soccer players (body height: 174.66 ± 5.01 cm; body mass: 72.83 ± 4.83 kg; age: 18.83 ± 0.75 years) was captured using six synchronized high-speed infra-red(More)
BACKGROUND Traditionally, stretching exercises are considered as basic components of warm up aiming to prepare the musculoskeletal system for performance and to prevent injuries. OBJECTIVES The purpose of this study was to examine the effects of different agonist and antagonist stretching arrangements within a pre-exercise warm-up on hip static (SROM) and(More)
The purpose of this study was to examine the effects of static and dynamic stretching within a pre-exercise warm-up on hip dynamic range of motion (DROM) during instep kicking in professional soccer players. The kicking motions of dominant legs were captured from 18 professional adult male soccer players (height: 180.38 ± 7.34 cm; mass: 69.77 ± 9.73 kg;(More)
The purpose of this study was to investigate enduring effect of static stretching, dynamic stretching and no stretching methods on power and agility in collegian soccer players. Fifteen collegiate soccer players (height: 173.07 ± 7.81 m; mass: 67.60 ± 8.73 kg; age: 24.73 ± 4.59 years; experience: 7.27 ± 2.09) were tested for agility performance using the(More)
The purpose of this study was to examine the effects of static and dynamic stretching within a preexercise warm-up on angular velocity of knee joint, deepest knee flexion (DKF), and duration of eccentric and concentric contractions, which are relative to the stretch-shortening cycle (SSC) during instep kicking in professional soccer players. The kicking(More)
The purpose of this study was to examine the effects of different stretching methods during warm-up on the power insoccer players.Therefore, nineteen professional soccer players (height: 173.37 ± 7.64 cm; mass: 68.12 ± 8.69 kg; age: 25.00 ± 4.56 years)were tested for power using vertical jump test after different warm-ups protocols consisting of static(More)
