A Comparative Study Of The Foot Movement Of Currently Outstanding Tennis Athletes On The Clay And Hard Courts For Men Singles

This paper uses literature method,video observation,comparative analysis,mathematical statistics research methods,four to six gait characteristics of elite male tennis players as the main research object,in the clay to them with hard court11 kinds of footwork,space,and better use of frequency between the characteristics of a horizontal,longitudinal comparative study,the results showed that:1,11 kinds of footwork on clay application characteristics as follows: the American sex footwork > defensive footwork > other footwork footwork > attack the closed rotating shot footwork;On the hard court its application features:offensive footwork gait > other defensive footwork > American footwork >closed rotary shot footwork.11 kinds of footwork used on two sites often have significant difference,mainly displays in A2 transfer footwork,B3,rotating body shots footwork,D closed rotary footwork its P < 0.05,the other eight footwork slightly different,but the difference is not obvious.2,11 steps using different athletes have distinguishing feature each,the same athletes in different ground has obvious bias footwork,performance in both in clay or hard courts are towards a particular type of footwork,six elite athletes in this type of footwork and choose one or two as their common steps in order to maintain their advantage in the competitive level,this is all belong to the gait feature of athletes themselves.3,in the clay and hard court 11 kinds of footwork longitudinal distribution is concentrated on the tennis court,transverse distribution is more dispersed,the same athletes by eleven kinds of step on the two sites show is no difference between the transverse,longitudinal difference obvious,longitudinal in disadvantage area and build the advantage area,clay to establish advantages outweigh the disadvantages areas,the opposite hard court.4,every step has its own obvious regional distribution characteristics.Attacking moves and hard on the clay court surface longitudinal areas are mainly distributed in the edge area followed by pressure area,regional distribution of horizontal main area in the left area and left,offensive moves in two different sites of each regional distribution difference is not obvious.5,six contestants in the clay,and hard courts,on the whole,the first gap is not big,0-2 fluctuations than the first,on the offensive moves clay is bigger than thefirst hard courts;American sex footwork and closed type rotating shot footwork hard points rate is relatively low,defensive footwork and T footwork allowing rate is greater than the clay on the hard court.6,no matter the clay hard court the points won obviously lower than that in the era is that athletes won a game victory is mainly depends on the opponent's mistake;Offensive moves serves in the high and low stretch.Gait of the remaining points rate is high,the first low,regardless of the clay hard points won the highest are offensive moves,the highest rate allowed are T footwork and defensive footwork followed by American sex footwork.Offensive moves are two major means of scoring in the field;Closed rotary footwork on two sites significantly better than the first difference is not obvious but 0-2 laterite hard courts.
