The purpose of this study is to find out if plyometric training has an effect on lower limb explosive strength and skill performance in Latin dancers.
The aim is to answer the following questions:
1. Does augmented style training increase dancers' lower limb explosive strength. 2. Whether plyometric training promotes specialized dance skills. 3. The relationship between lower limb explosive strength and specialized dance skills.
The researchers set up an experimental group and a control group, the experimental group uses plyometric training and the control group performs traditional training, and finally, between-group and within-group comparisons are made.
Participants will:
Train for 90 minutes three times a week for eight weeks. Participants' lower limb explosive strength and skills will be measured before the start of the experiment and at the end of the experiment.
Have at least one year and more hours of Latin dance study.
Must be a current university student.
Athletes who were systematically training their explosive strength.
Athletes with sports injuries such as ankle or waist injuries who could not follow the entire training schedule for two months.
Parallel
Plyometric training for experimental group
Other interventionThe experimental groups will undergo 3 interventions a week, with one session lasting 90 minutes. The experimental group will perform 15 minutes of dynamic stretching, 30 minutes of Latin dance-specific technique training, 30 minutes of plyometric training, and 15 minutes of relaxation stretching.
Traditional training for control group
Other interventionThe control group will perform 15 minutes of dynamic stretching, 30 minutes of Latin dance-specific technique training, 30 minutes of general training, and 15 minutes of relaxation stretching.
Change from baseline Countermovement Jumps at 4 weeks and 8 weeks
This parameter belongs to Explosive Strength. Participants test using either arm swing or crossed hips (without any arm swing) while performing vertical longitudinal jumps on a smart jumping mat. The participants in this research uses a cross-legged waist when performing both the pre-test and post-test. The Smart Jump Pad in this research has been performed to measure the performance of the CMJ by providing signals from the platform in an iPad 7,5 IOS 12.1.1). When the test equipment is ready, under the direction of the test administrator, the experimenter stands on the Smart Jump Mat and performs a vertical longitudinal jump. The experimenter jumps to the best of their ability and each jump was automatically recorded on the iPad. The unit is "cm". subjects will test three times and record the maximum height.
Change from baseline Standing Long Jumps at 4 weeks and 8 weeks
This parameter belongs to Explosive Strength. Participants stand slightly apart in front of the jump line, bend their knees, and move their arms backwards, then swing their arms and jump as far as possible; Stand on both feet while maintaining an upright position. Measure the furthest horizontal distance. The unit is "cm". Participants will test two times and record the farthest distance.
Change from baseline 20m-sprint at 4 weeks and 8 weeks
This parameter belongs to Explosive Strength. Use a stopwatch to record the duration of the participants' 30 m sprint. Set cones at 0 and 20 meters along a straight line. Participants place their toes on the starting line or behind the starting line, start from a stationary position, and sprint at maximum speed over the cone at a distance of 20 meters before safely slowing down. Test the time it takes to run a 20-meter sprint. The unit is "second(s)". Participants will test two times and record the fastest time from two tests.
Change from baseline Posture at 4 weeks and 8 weeks
This parameter belongs to Dance Performance. Using a video camera, a recorded video of the Cha Cha Gold Medal solo routine is send to the 6 judges, and the pre- and post-tests need to be rated using the same criteria 'the Latin Dance Technical Quality Elements of World Dance Sport Federation (WDSF) 2.1 Evaluation System'. The score range is 1-10. These subjects are college students with a basic level of Latin dance, so a minimum score of 6 and a maximum score of 10 have been determined. There are three levels, very excellent (10 points), excellent (8 points), and average (6 points). The total score given by the six experts will be recorded and the average score will be calculated. The higher the score, the higher the level of Latin dance.
