CHAPTER 1INTRODUCTION1.0 Background of the Study Jumping or rope jumping techniques are known as an easy sport, a simple and an excellent physical exercise. Skipping is a low-cost, indoor activity and the exercise takes up little space and can be practiced anywhere. Skipping activity will help us improve our level of health and fitness. More importantly, it can burn a calorie which in turn reduces body fat that causes high blood pressure, high cholesterol and heart disease. Beyond that, jumping can improve cardiovascular fitness, flexibility, explosive muscle power, agility, foot speed and coordination. Additionally, it can increase bone density and lose weight. Skipping has been an important exercise technique for many athletes in sports such as boxing, tennis, running and martial arts. Skipping has become popular among athletes because it is one of the methods that can maintain cardiovascular health and increase fitness more quickly. It can also be used as a stretch after doing light aerobic activity as part of your pre-exercise warm-up. During stretching, it has been shown to be an effective means of increasing the range of motion (ROM) of the joint and normally serves to decrease muscle pain, reduce or prevent the danger of damage due to strained muscles and rehabilitation after a injury [1].Jumping requires the coordination of different muscle groups to support the rhythmic and precisely synchronized movement that is an integral part of the exercise. As you perform a jump, your upper body, core and lower body muscles respond. The muscle plays an important role in the successful execution of skills in many games and sports. Most of these other sports that use but... middle of paper... needed bouncing on the rope with one leg in rotation. Perform two or three one-foot jumps before the exchange. Figure 3.7: One-foot jumping technique 3.2.4 Side to side Starting in the basic two-foot jumping position, start performing the same jump normally. For this technique you need to jump using both feet and start jumping from side to side. This technique can begin by performing short lateral jumps first, then advance to longer lateral jumps.
