CHANGES IN ANAEROBIC POWER OF YOUTH SOCCER PLAYERS IN AN ANNUAL TRAINING CYCLE
International Scientific Congress "Applied Sports Sciences" 1-2 December 2017, 2017
Introduction: It is a well-known fact that short high intensity actions are decisive for football game. The energy for these actions is ensured from anaerobic energy system. The lack of information about this subject defines the aim of our research which was set as research of changes of indicators which characterize anaerobic power of youth football players. Methodology: It includes the following methods of research: anthropometry, chronometry, test of exercise bike and statistical analysis. Results: The data from Wingate test are proof for increasing of the average values of the most informative signs of this test. We found out statistical improvement of the values of the signs such as Peak power (PP), Average power (AP) and Minimal power (MP). Their values increase from 539.96 to 721.54 watts for PP; from 410.58 to 514.07 watts for AP and from 277.23 to 339.15 watts for MM. The same improvement of 1.66 seconds we can see from the data of the field test " 3x50 m shuttle ". Discussion and conclusions: As a whole this research found out improvement of the informative signs from laboratory and field tests in the annual training cycle. Statistical non-significant improvement was found only in the indicator MM from second to third test. This fact leads us to the conclusion that this indicator is not good enough to detect changes in a short period of time. We also found improvement of the PP and AP respectively with 33.63 and 25.20%. Our study is in unison with the conception that the period of 13-14 years is suitable for development of the speed and speed endurance abilities.

Comparative Study of Aerobic and Anaerobic Power In Football Players and Control Group
Aerobic power is best indicated by VO 2 max. VO 2 max is maximum capacity of individual's body to transport and utilize the oxygen during exercise, which reflects the physical fitness of individual. Anaerobic power is power produced in absence of oxygen. Anaerobic capacity is useful in sprints in football players. Aim: To determine values of VO 2 max and anaerobic power in football player and control group.
The purpose of this study was to observe and report anaerobic power and capacity of football players. The design of this study required participants to perform six sprints each of 35 meter. Thirty six (N=36) male football players between the ages of 17 and 28 years volunteered for this study. The mean age, height and weight of football players was 21±2year, 172±6.81cm and 67.50±9.94Kg respectively. The mean sprint time of 1 st ,2 nd ,3 rd ,4 th ,5 th and 6 th sprint of football players was 5.50±0.39 seconds, 5.50±0.55 seconds, 5.57±0.56 seconds, 5.78±0.55 seconds, 5.83±0.59 seconds and 5.88±0.62 seconds respectively. The mean power generated during the 1 st , 2nd, 3rd, 4th, 5th and 6 th sprints by football players was 506.94±119.65 watts, 522.58±165.63 watts, 490.64±134.88 watts, 443.72±137.38 watts, 438.17±132.76 watts and 422.22±130.16 watts respectively. The maximum power, minimum power, average power and fatigue index of football players was 579.94±147.78watts, 376.00±111.66watts, 470.78±114.76watts and 6.00±3.45 respectively. It was concluded from the results of this study that sprint time increased, power declined with a high fatigue index, the football players may need to focus on improving lactate tolerance and this could be a focus of their training programme.

The purpose of this paper is to compare the anaerobic power values and sprint performances of football players playing in different positions and to evaluate the association between these. A total of 40 male football players participated in the study voluntarily. For this aim, 20, 30 and 45.72 m sprint tests, vertical jump and Wingate anaerobic power tests were performed on the football players. The results of this study showed that there were significant differences for all the sprint tests. Moreover, statistically significant positive correlation was found between all the sprint tests, while statistically significant negative correlation was found between sprint and vertical jump tests. In addition, a negative correlation was found between 30 m sprint and peak power values. Also, the negative correlation found between the sprint and vertical jump values brings to mind that vertical jump trainings can be used to improve the ability of speed.
EFFECTS OF DIFFERENT TRAINING MODALITIES ON AEROBIC AND ANAEROBIC CAPACITY OF SOCCER PLAYERS
The purpose of present study was to investigate the effect of different training modalities on aerobic and anaerobic capacity of male soccer players. Sixty male football players between the age of 16 – 20 year of age from Jabalpur, Chinndwara and Tikamgarh (M.P.) those who regularly participate in training and inter district competitions, were selected for the present study. Random group design was used to evaluate the effect of different training modalities. The selected subjects (N=60) were randomly divided into three groups with subjects in each group out of which experimental group-I underwent the plyometeric training. Experimental group II underwent specific training thrice in a week along with two days match practice. Group-III (control group) participated in their regular game for 12 weeks the 80 minutes to 90 minutes training was devoted towards warming up and stretching. The pre and post tests were administered to the subjects at the play grounds and tracks. Before administering the tests the subjects were given proper warming up under the supervision of the research scholar. Aerobic Capacity and Anaerobic Capacity were identified for the present study. Anaerobic capacity: Margeria Kalamen power test. Anaerobic capacity was estimated by using the formula. Power watts = (M x D ) x 9.8/t. Aerobic capacity: Estimated using cooper 12 min run/walk test and VO2 Max was determined by the formula VO2 Max = 22.351 x distance covered in km – 11.288. Unit of measurement is (ml per kg per min). In order to compare the effectiveness of different training modalities, means, standard deviations and one way Analysis of Co- Variance (ANCOVA) was computed. . In case of significant F-ratios, the Least Significant Difference (L.S.D) Test of Post hoc Comparison was used to find out the specific group differences. The level of significance was set at 0.05 level of confidence. The results of study revealed that the twelve weeks systematic training programme consisting of plyometric exercises had contribute effect on anaerobic capacity of football players. But the plyometric exercises did not have any significant effect for improving the aerobic capacity of football players.
Aerobic and anaerobic capacity of adult and young professional soccer players
Sport Sciences for Health, 2012
While VO 2max has been widely investigated, there is few research on anaerobic capacity (AC) in soccer players. Previous studies reported that AC is age-dependent and that young individuals had lower AC compared with adults. Thus, we wondered whether AC would have proven more useful than VO 2max in differentiating adult soccer players from young players. A total of 37 male athletes from a professional team were recruited and divided into two sub-groups: the adult (AD, n = 20) group, older than 19 years, and the young (YO, n = 17) group, ranged from 16 to 18 years. Each participant underwent an incremental test on a treadmill to assess maximal velocity (V max ), anaerobic threshold (AT) and VO 2max and a supramaximal exercise at a velocity 10 % higher than V max to measure AC. The AD group reached higher AT and VO 2max with respect to the YO group (55.23 ± 4.65 vs. 51.48 ± 4.73 mL min -1 kg -1 ), whereas no difference was found in parameters related to the AC. In conclusion, young soccer players had the same AC as adult, but they displayed a lower VO 2max . These findings indicated that AC in professional players is fully developed already when they are young while aerobic capacity is still to be developed.
Football is characterized as a predominately aerobic modality, however, during a match; the most important actions performed by the players are in short duration and high intensity. In addition, this sport presents to have some particularities, such as, highlights differences of each tactical position. Thus, this study aimed to compare the anaerobic power of professional football players grouped by different tactical positions. Thirty professional football players separated in three groups, goalkeep-ers+fullbacks, sideways+DMF (defensive middlefields) and OMF (offensive middlefields)+forwards, performed two anaerobic power tests, Running anaerobic sprint test and Sargent jump test Goalkeepers+fullbacks showed higher values of body mass index and absolute anaerobic power (w), using Sargent jump test than the others, but when analyzed the RAST results, this same group presented lower values (p<0.05) of relative AP (w·kg-1). OMF+forwards showed to have the best Pmed and Pmax values (p<0.05), when compared with defensive players. These results suggest the use of running anaerobic sprint test and sargent jump test together when is proposed to measure the anaerobic power of football players, and also a anthropometric evaluation, so the training can be more specific e efficient to each tactical position and athlete.
Anaerobic resistance of soccer players
Fitness & Performance Journal, 2009
Introduction: Anaerobic resistance, i.e. the capacity to perform repeated series of anaerobic exercises at the maximum, is an indispensable feature for soccer players. The aim of the study was thus to determine the anaerobic resistance of soccer players by applying repeated maximal sprints. Materials and Methods: A group of 14 soccer players aged 19-27 years-old was subjected twice, in January and March, to a test consisting of maximal running 6x50 m with 15s intermissions between runs. The registered times were converted to speeds. The ratio of average speed to the maximum one achieved in all 6 runs, or the Performance Index (PI), was the measure of anaerobic resistance. Results: Average and maximum speeds were signifi cantly (p<0.001) higher in March (5.47 ± 0.25 and 5.67 ± 0.28, respectively) than in January (5.73 ± 0.31 and 5.97 ± 0.31, respectively), although still rather low. The PI values were on both occasions alike (0.960 and 0.965) and were not correlated with maximum speeds. Discussion: The presented method may serve as a useful tool in determining and classifying athletes with respect to their anaerobic resistance by applying repeated series of specifi c exercise.
Normative Data of the Wingate Anaerobic Test in 1 Year Age Groups of Male Soccer Players
Frontiers in Physiology, 2018
The Wingate anaerobic test (WAnT) has been used extensively to evaluate performance in soccer, however, a comprehensive sport-specific normative database has not been available so far. Therefore, the main aim of the present study was to develop norms of the main indices of the WAnT with regards to age in soccer. A secondary aim was to examine the relationship of WAnT with two common field tests, 20 m sprint and vertical jump, and study the variation of this relationship by age and playing position. Hundred and ninety five male soccer players (age 18.1 ± 4.9 years) performed the WAnT, and a sub-sample of 190 soccer players (age 19.4 ± 5.1 years) performed 20 m sprint, squat (SJ) and countermovement jump (CMJ). Age was related very largely with peak power (R 2 = 0.57) and mean power of the WAnT (R 2 = 0.60) when they were expressed in W, and largely (R 2 = 0.41 and R 2 = 0.33, respectively) when they were expressed in W.kg −1 , whereas it did not relate with fatigue index. After being adjusted for age, a relationship of SJ (B = 3.91, 90% CI: 2.49, 5.32; R 2 = 0.26), CMJ (B = 3.59, 90% CI: 2.22, 4.95; R 2 = 0.24) and 20 m sprint (B =-0.06, 90% CI:-0.10;-0.01; R 2 = 0.19) with peak power of the WanT was observed. In summary, P peak and P mean were related very largely to age, especially during adolescence, and percentile norms of these indices were developed for 1-year age groups from 11 to 21 years old and for a single adult age group (22-39 years old). These findings on the largest dataset of soccer players ever studied would be expected to offer a practical tool to the members of the sports medicine team (e.g., exercise physiologists, fitness trainers, and coaches) working with them.
