Investigating the Effect of Skill Related Physical Fitness on the Development of Technical Ability in the Case of Debre Markos University under -17 Male Football Project Players

This study aims to investigate the effect of skill related physical fitness on the development of technical ability: in the case of Debre Markos University under-17male Football project players. Explosive leg power, speed, agility physical fitness components and distance accurate shooting and speed dribbling technical components of Football project players were the main target of the study. They were 25 in number but due to injuries 2 players excluded whereas the remaining all 23 players were selected by using purposive sampling method. The average age of the participants’ was 16±0.756 years. To assess the level of physical and technical components of the player’s field test was used. The data was analyzed through multivariate and simple linear regression statistics method. The finding of the study showed that most of the players had very poor level of power performance, excellent level of speed and agility performance when we compared with the international standard of physical fitness level. On average, accurate shooting increased by 3.241 times significantly when explosive leg power increased by 1 meter, On average, speed dribbling was increased by 6.847 second times significantly when speed increased by one second and On average, speed dribbling was increased by 1.628 second times significantly when agility increased by one second. Therefore skill related physical fitness (explosive leg power, speed and agility) had their own effect on the development of technical ability in football.


Back ground of the study
Soccer is one of the most widely played and complex sports in the world, where players need technical, tactical, and physical skills to succeed. Without good physical fitness, players are rarely able to play the game with good technique, (Chapman.et al, 2007). For achieving top results in this sport, it is necessary that players have an exceptionally high level of technical and tactical skills as well as significant physical fitness, (Sevensson& Drust, 2005).
Fitness in soccer specific context refers to a range of individual characteristics that is a composite of many attributes and competences. Such competence by definition includes, physical, physiological, and psychomotor factors, (Reilly & Williams, 2003). Physically superior players feel less fatigued during the game played with the same intensity and, therefore, those players experience less decrement in technical performance, (Jukic, et al, 2011).
Modern football requires the player to have high physical abilities has become one of the main pillars in training plan either daily, weekly, seasonally, and annually. Player's abilities significantly increased in the world in the recent years on looking at players now and years ago, we find that their physical abilities have grown in a remarkable way Hanafi (1994). Players in competitive soccer require high levels of power, speed, and agility to perform explosive movements such as heading, shooting, sprinting, and dribbling, (Stolen,et al.,2005).The various codes of football played around the world have much in common in terms of their physical demand and correspondingly the importance of fitness testing (Pyne.etal, 2014).
Technical preparation of football players is the main precondition for efficient motion performance. More precisely, technical preparation enables that motor potential of a soccer player reaches its maximum. We have to stress that further progress in terms of technical improvement of a soccer player is not possible without parallel work on development and maintenance of those motor abilities which are vital for the game of football (Smajić, M., Molnar, S., 2007).
The context of this study was on Debre Markos University under-17 male football project players. Debre Markos is found in Ethiopia specifically in Amharal region, the capital city of East Gojjam zonal administration. Debre Markos University under-17 male football projects is found in Debre Markos city. It was consisted 25 players. This study involves from the total number of 25 trainees only 23 participants were used as a subject but the remaining 2 trainees due to injury were excluded. The specific objectives of this study was to check skill related physical fitness level of Debre Markos University under-17 male football project players go in line with international test standards, to Evaluate the effect of explosive leg power on distance shooting and to assess is the effect of speed and agility on the development of speed dribbling.

Material and method
Aiming to study the effect of skill related physical fitness on the development of technical ability: in the case of Debre Markos University under-17 male Football project players; this study covers 25 trainees in the age of 16-17age groups, who train for football at Winter Sports University. This study involves from the total number of 25 trainees only 23 participants were used as a subject but the remaining 2 trainees due to injury were excluded. Their average age was 16±0.756.
All testing candidates underwent a systematic medical examination which is a standard procedure. Therefore, all the testing candidates are healthy and with no visible aberrations that might affect testing results in the research. Before directly engaged to the test the participants were requested to warm up for 12 minutes prior to the test program and cooling-down for 8 minutes following the test program. Standing long jump pre-test was applied to test trainees explosive leg power, 30 meter accelerate run pre-test was applied to test trainees speed ability and Illinois agility run per-test was applied to test their agility abilities. Counting accurate and non-accurate shooting from 30meters distance far from the goal line per-test was applied to measure shooting development and speed dribbling pre-test was applied to test speed dribbling development. For the purpose of this research, and in accordance with the research aim, multivariate linear regression was used to evaluate the effect of explosive leg power on distance accurate shooting and simple linear regression method was used on the effect of speed and agility on speed dribbling abilities.

Results
Based on the gained data, we can see from Table 1 Table 5 indicates that on average, speed dribbling was increased by 6.847 second times significantly when speed increased by one second. .000 Table 6 indicates that on average, speed dribbling was increased by 1.628 second times significantly when agility increased by one second. The setting of today's football requires faster and faster players that would be unpredictable and elusive for the opponent. Speed as a basic motor ability is very important in the execution of technical elements in the football game (Milenkovuic, D., (2011).

Conclusion
Based on the research data, it can be concluded that:-Most of the players have very poor level of power performance, excellent level of speed and agility performance when we compared with the international standard of physical fitness level. Players who had average explosive leg power performance had good distance accurate shooting than those who had poor and very poor explosive leg power, players who had excellent and above average speed and agility performance had good speed dribbling technique in football than those who had average and below average speed and agility. Generally explosive leg power has their own effect on distance accuracy shooting and speed and agility has their own effect on speed dribbling.
