Effect of Resistance Training in Water Combined With Land on Starting and Turning ,12-weeks Resistance Training

Study Overview
=================
Brief Summary
-----------------
Resistance training has been widely used in various sports and is a common practice aimed at improving competition performance, especially in swimming. Swimming performance is highly dependent on muscle strength, especially short distances. Water or land resistance training can improve the swimming performance, especially the swimming performance of 50 meters and 100 meters. Both type of training has their own strength and weakness. Hence, combining both methods strength may enhance swimmer performance. In addition, competitive swimming consists of different stages, namely start, clean swim, turn and finish. However, there is no literature on the influence of resistance training on starting and turning.

Detailed Description
-----------------
Through experimental design and quantitative research methods. In this experiment, the resistance training method of water combined with land was used to intervene the turning and starting of young people, and the traditional strength training was compared to find out a better training method. The experiment will use 12 weeks of resistance training to improve the swimmer's turn and start intervention. The experiment consisted of four groups, 20 boys and 20 girls in the experimental group and 20 boys and 20 girls in the control group. Compare the differences between the two groups. Divided into discussion groups and general teaching groups. Two of the most significant differences, this experiment aims to provide a theoretical basis for improving the training methods of swimming, so that young swimmers can get better swimming performance, especially on the start and turn. Experiment Group Week1-3: Drag Umbrella , Resistance Bands, Swiss Ball, Hand Resistance. Week3-6: Drag Umbrella , Resistance Bands, Swiss Ball, Hand Resistance. Week6-9: Drag Umbrella, Pulley Pull, Medicine Ball, Resistance Suit. Week9-12: Drag Umbrella Pulley Pull, Medicine Ball, Resistance Suit. Control Group Week1-3: Sit-Up, Press-Up, Deep Squat, Lift Heel Week 3-6: Sit-Up, Press-Up, Deep Squat, Lift Heel Week6-9: Dumbbell, Barbell ,Stomach Up, Squat Up Week9-12: Dumbbell, Barbell, Stomach Up, Squat Up

Interventional Model Description: In this experiment, the combination of water and land resistance training method was used to intervene the teenagers' turning and starting, and compared with the traditional strength training method
Masking: Triple


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: 1.Drag Umbrella 2. Hand Resistance 3.Resistance Suit<br>In the water, a small umbrella is attached to the athlete to increase resistance. In the water, increase resistance by increasing the area of the hand. In the water, use swim shorts that increase resistance | Other: Resistance training that combines water and land<br>* Device: Swimmers in the experimental group received resistance training in water for 12 weeks, and the resistance training in the experimental group was divided into 3 categories:Resistance palm and resistance umbrella, resistance suit. Device: The swimmers in the experimental group underwent core strength training on land for 12 weeks, and the resistance training in the experimental group was divided into 4 types of resistance zones: Swiss ball, medicine ball and drive zone.The combination of two resistance training methods can improve teenagers' swimming performance.<br>|
| Experimental: 1 Resistance 2 Bands Swiss Ball 3 Medicine Ball 4 Pulley Pull<br>On land, use a stretch rope to increase resistance. On land, inflatable bouncy balls are used to increase strength. On land, solid balls are used to increase strength. On land, pulleys are used to increase resistance. | Other: Resistance training that combines water and land<br>* Device: Swimmers in the experimental group received resistance training in water for 12 weeks, and the resistance training in the experimental group was divided into 3 categories:Resistance palm and resistance umbrella, resistance suit.
