The impact of an eight-week aerobic and strength-training programme on agility and leg power of Malaysian netball players

The purposes of the study were: (1) to determine the agility and leg power among Malaysian national junior netball players and (2) to determine the impact of eight-week aerobic and strength-training programme on these two variables. A total of 21 netball players from Bukit Jalil Sport School were selected as the subjects in this study. The SEMO Agility Run test was used to determine the agility level while leg power was measured using the Vertical Jump test. Pre-test and post-test results showed no significant differences in the agility and leg power level among the netball players. The mean values for the agility and leg power post-test were 12.59 (SD = 0.56) seconds and 50.24 (SD = 4.90) cm respectively. The pre-test and post-test results for different playing positions recorded the highest improvement in agility and leg power among attacker, followed by centre, and defender. Thus, the training conducted in this study was found to have improved agility and leg power marginally, especially among attacker and centre netball players.

The Charactaristic of H-shape sport's mouth guard on athlete's physical capacity. Part II Effect on the leg power and golf perfomance / 体力科学

We have developed a mouth guard which has revolutionized the shape and material of the conventional mouth piece. The H shape mouth guard has the unique shape like that of an H. Even with the new shape of the mouth piece it does not hinder the performance of the wearer. The following are the fundamental data collected by our group. In this study we examined its influences on leg power, the carry (the distance a golf ball is hit) and the motion of the club head during a tee off.<BR>The results are as follows:<BR>1) By wearing or setting the mouth guard, the variation of leg power, measured with a Sybex II, showed an increase at selected angular verocity. The rate of increase averaged aproximately 15%.<BR>2) The amount of work in anaerodush, an intensive, but short exercise, increased significantly by 1.25 seconds.<BR>3) As for golf, all four of the test subjects joint performance increased their carries by 5.2 to 11.6 yards, using a 1st wood.<BR>4) Also the fluctuation of the head of the club decreased from 7.3 cm to 3.6 cm on average.<BR>Our group have found that the new H shaped mouth guard can absorb shock as well as not hinder the performance of the individual who is wearing it. Thus, the H shape mouth guard can be worn during sports to enhance the participant's performance.
