Effectiveness of Temporal Structure for Forehand and Backhand Straight Strokes Performance According to Rebound Time in Squash

Abstract

This research was conducted to identify the effectiveness of temporal structure for forehand and backhand straight strokes performance according to rebound time in Squash. Descriptive design was used. Study participants consisted of seven Squash players were internationally classified from Official Women's Squash World Ranking participated in the Women's World Open Squash Championship Cairo 2014. With following characteristics: mass 61.16± 5.87kg, and length 165.67± 3.72 cm. Strokes had monitored and analyzed of the seven matches in Women's World Open Squash Championship 2014, matches of quarter-finals, semi-finals, and final match. Dartfish v.7 software motion analysis used to analysis 1256 strokes (463 straight forehand strokes and 793 straight backhand strokes) by using normal motion, slow motion, frame by frame, and stop cadre. Phases of skill performance had classified into preparatory, execution and follow-through phases. Times of skill phases had divided into: first period from 0.001-0.127 part of second, second period from 0.128-0.255 part of second, third period from 0.256-0.510 part of second and fourth period from 0.511-1.0 second. The rebound time of the ball had divided into fast, moderate, and slow rebound. Statistical analysis was done with SPSS software package by using mean and standard deviation. It is concluded that, levels of effectiveness had increased in fast, moderate, and slow rebounds during performance of forehand and backhand straight strokes in first and second periods during the three phases of skill performance. Also the effectiveness degree of backhand straight strokes had elevated during preparatory and follow-through phases in third period.
