Effects of Foam Rolling Compared to a Dynamic Warm-up on Vertical Jump Performance

INTRODUCTION Warm-up and stretching are widely accepted as a prerequisite for participation in athletics, strength training, and aerobic training. The general idea of ​​warm-up and stretch is to improve performance and reduce the risk of injury (Hough, Ross & Howatson, 2009). Another general idea for warm-up procedures is to raise muscle and body temperature to increase nerve conduction velocity, thereby improving performance (Behm & Chaouchi, 2011). Numerous research papers showing various types of warm-up and stretching effects have been published.

Various studies have been conducted to observe the effects of dynamic stretching and plyometrics on vertical leap and agility in various sports and age groups. Most research literature proves that it is effective and acceptable for these variables. The purpose of this study was to understand the combined effect of vertical leap and dynamic stretching against agility and strengthening training program of male university basketball players. Most sports need fast muscle activity. Muscle activity depends on the nature of the game. Basketball is a game that requires lower limb activity as people require more agile and require to participate in many jumping activities. In order to achieve or provide better performance, basketball players need to improve their skills. There are various training methods to choose from. Each method has different advantages. The available training methods are different, but not all methods give the same results.

Comparing the effectiveness of the vertical hopping performance, the reinforced group is improved over the dynamic group. Stretch shortening cycle jump is thought to improve vertical performance. It is also enhanced by the use of stretching to shorten the cycle elasticity and nerve benefits. (Goran Markovic, 2007). By combining two types of training you can receive more training in training improvement than using one training. Plyometric improves jumping performance by activating muscle filaments and helps to improve power by reducing muscle stiffness.

Upright vertical jump is a common test of leg strength and is often used to monitor the effectiveness of athletic training programs. For most tests, the players need to do "reverse movement" (using the arms) to get the maximum height. A reverse jump means starting a jumper from an upright position, bending the knee or waist and moving downward, immediately extending the knee or butt and jumping vertically upward from the ground 1a). This movement uses "stretch-shortening cycle" and the muscle "pre-stretches" before being shortened in the desired direction.
