We aimed to evaluate dribbling performance in terms of technique and visual skills assessment of both young experienced (EX, n = 24) and novice (NO, n = 24) soccer players. Both groups performed two dribbling tests with four levels of difficulty in visual signals (A1-A4 and B1-B4; B - half distance of A; 1 - no visual signal; 4 - signal with the shorter flashing time). All players performed slower when visual signals were added to the testing process (~2.5 s; p < 0.01). EX completed all tests faster than NO (~3 s, p < 0.01). The average number of visual mistakes was significantly lower for EX than NO in all tests (p < 0.01). These results demonstrated the importance of evaluating dribbling along with visual stimuli in young soccer EX and NO players.
BACKROUND: New training methods are constantly used to improve the ability of skeletal muscles to develop strength. OBJECTIVE: The aim of the present study was to investigate the effect of half-squat training with free weights and flywheel device on isokinetic knee muscle strength for well-trained amateur soccer players. METHODS: Forty eight players were randomly divided into three groups (n= 16 each): Desmotech Training group (DT), Free Weight Training group (WT) and one Control Group (CON). DT and WT performed an eight-week half-squat training program, with two sessions per week. The DT group performed training with a flywheel device. Isokinetic concentric-eccentric strength assessments of the knee extensors-flexors muscle groups were performed at different angular velocities (60, 180 and 240∘/s). RESULTS: The eight-week training program improved all the isokinetic joint moment indicators examined in the DT and WT groups (p< 0.01). The DT group achieved higher performances at all the isokinetic parameters examined, however, without statistically significant differences to the WT group. CONCLUSIONS: Flywheel-based exercise is an effective training method and is suggested to be used to strengthen the lower limbs of soccer players.
The aim of this study was to compare the internal and external loading between official matches and the in-season qualitative trainings in soccer. Nine professional soccer players (N=9) aged 29.5±2.75yrs, with body mass of 74.9±5kg, stature 180±14cm and body fat of 7±1.6% participated in the study. The selected parameters were recorded by the use of a Polar Team Pro GPS system in both two official matches and in two of the most demanding trainings in a period of 4 microcycles. The players’ loads duration in a max heart rate (HRmax), the covered distance and the amount of accelerated/decelerated runs were measured. The paired samples t-test revealed that the load time (min) with heart rate close to 50–59.9 and 60–83.9 %HRmax was significantly greater during trainings, rather than the match. On the contrary, when the players’ heart rate corresponded to 84–89.9 and 95–100 the values of HRmax were significantly greater during the match. In addition, the covered distance with a playing intensity of 19.8-24.99km.h-1 and >25km.h-1 was lower while the amount of accelerated and decelerated runs was greater during training, in comparison to the match. These findings suggest that, to become the soccer players able to respond in match conditions, coaches should replace the low intensity loads with higher, simulating as close as possible the demands of the official match.
This study examined the effects of an alternative strength training method during soccer training on the development of physical and technical abilities of youth soccer players. 17 soccer players (age: 15 ±0.5 years) were divided in a control #0#
