The aim of this study was to examine the effect of a soccer (strength and technique) training program on kinematics and electromyographic (EMG) muscle activity during a instep kick. Ten amateur soccer players (aged 19.9+/-0.4 years, body mass 74.8+/-9.1 kg, height 177.4+/-6.7 cm) constituted the experimental group (EG) whereas 10 players (age 21.6+/-1.3 years, weight 71.5+/-6.7 kg, height 175.2...

Background. Instead of different measurements of physical performances such as postural control, strength, and flexibility, studies investigating many abilities such as the harmony between these abilities and body segments simultaneously with the test FMS results and different physical relationships were performed. Meaningful results and other relationships between COD, FMS, and PC have previou...

BACKGROUND The purpose of this study was to evaluate the role of ventilatory parameters in maximal exercise performance in elite soccer players. METHODS From September 2009 to December 2012, 90 elite soccer players underwent evaluation of lung function test and ergospirometry by means of an incremental symptom-limited treadmill test. Results were analyzed according to i) maximal exercise velo...

This study examined the change in countermovement jump (CMJ) performance across a microcycle of training in professional soccer players during the in-season period. Nine elite youth soccer players performed a CMJ test before and after 4 consecutive soccer training sessions of an in-season weekly microcycle. Training load was quantified using global positioning systems, heart rate, and rating of...

The aim of this study was to examine the effect of a six-week combined jump and sprint training program on strength-speed abilities in a large sample of youth competitive soccer players. It was hypothesized that the experimental training group would enhance their jumping and sprinting abilities. Enhancement of kicking performance was also hypothesized due to an expected increase in explosive st...

The aim of this study was to determine the effect of 3 post-match recovery modalities on physical performance, physiological measures, and players' perceptions of recovery after 90-minute soccer match play. On separate days, 28 young (age: 14.3 +/- 0.7 years) soccer players played 3 soccer matches each randomly followed by 1 of 3 recovery modalities: (a) CONT-cold (12 degrees C) water immersion...

Background Although trainers and athletes consider ‘good timing skills’ to be critical for optimal sport performance, little is known in regard to how sport-specific skills may benefit from timing training. Thus, assuming that all motor performances are mediated by an internal timing mechanism, enhanced motor timing is expected to have positive effects on both planning and execution of movement...

Background. Soccer, combat sports and motorcycling have all been classified as mixed in terms of their metabolism predominance thus showing a common multifaceted nature of physical requirements, which include aerobic capacity, strength, endurance, power and agility. Objectives. The aim of the current study was to compare allelic and genotype frequencies of four well-known polymorphisms among a...

In sports, fast and accurate execution of movements is required. It has been shown that implicitly learned movements might be less vulnerable than explicitly learned movements to stressful and fast changing circumstances that exist at the elite sports level. The present study provides insight in explicit and implicit motor learning in youth soccer players with different expertise levels. Twenty...

BACKGROUND No previous research has analysed kinetic fatigue of elite adult players and elite youth players during the competitive period. OBJECTIVES The aim of the present study was to analyse kinetic post-match fatigue in professional and youth soccer players during the competitive period. MATERIALS AND METHODS resting heart rate (HRrest), post-effort recovery heart rate (HRrecovery), rat...
