Some Anthropometric Measurements and Sensor motor Perceptions and their Relation to Performance Level of Individual Play for Speedball Players

1- Identify the relationship between some (A.M) () and the level of performance of the 
individual play of speedball players.
2- Identify the relationship between some of (S.M.P) and the performance level of the individual play of speedball players.
3- Identify the contribution of some (A.M) (circumferences- ocean- widths) in the level of performance of the individual play of speedball players.
4- Identify the contribution of some of (S.M.P) in the level of performance of the individual play of speedball players.
Research questions:
1- Is there statistical significant correlation between some (A.M) (circumferences- ocean- widths) and the level of performance of the individual play of speedball players?
2- Is there statistical significant correlation between some (S.M.P) and the performance level of individual play of speedball players?
3- Do some (A.M) (circumferences- ocean- widths) contribute in performance level of individual play of speedball players?
4- Do some (S.M.P) contribute in performance level of individual play of speedball players?
Terms used in the research:
Individual Play in Speedball:
The player who practices on his own in a race against time in an attempt to hit the ball with a single bat (left or right) or two bats (front-back), achieving the largest number of correct strikes during certain predetermined time in the four positions. (10: 31-34)
Research procedures:
Research Methodology:
In light of the nature of the research and within the limits of objectives, the researcher used the descriptive survey method because of nature of the research.
Population and research sample:
The research population includes the players of the Cairo, Ismailia, Kafr El-Sheikh, Suez, Al-Gharbia, and the size of the sample include (40) players under the age of 21 for the 2015/2016 sports season. The researcher excluded (10) players to conduct pilot study to find scientific coefficients on them and thus became the basic study sample included (30) players,
