What Does Warm up and Cool Down To Our Body??

 What is WARM UP?? A warm-up is a pre-exercise phase that usually consists of low- to moderate-intensity movements and activities. Its main goal is to progressively raise the body's core temperature, pulse rate, breathing rate, and blood supply to the muscles that are in use. The purpose of a warm-up is to get the body ready for more physically and psychologically taxing activities and exercise. Many exercises, including dynamic stretching, light aerobics, and sport-specific drills , are frequently used as part of a warm-up. These exercises improve brain activation, joint mobility, and muscular flexibility. A warm-up also makes it easier for oxygen to reach the muscles efficiently, which enhances energy metabolism and lowers the chance of injury. The warm-up phase facilitates the change from a state of inactivity or rest to one of physical exertion preparation. It is seen as a crucial part of any fitness programme, helping to enhance performance, reduce injuries, and promote gener

Characteristics of Open-Chain and Closed-Chain Exercises

The following definitions are informational and Represent characteristics of open- chain exercises  and closed-chain exercises . they are presented for understanding and for the discussion of open-chain exercises and closed-chain exercises described throughout this is also referred to as  kinetic exercise. Kinetic Exercise Refers to  body kinetic which is Representing the Kinematic changes occurring in rhythm in the body. Open-Chain Exercises Open-chain exercises involve motions in which the distal segment (hand or foot/the joint far from the joint where the movement is occurring) is free to move in space, without necessarily causing simultaneous motions at adjacent joints. Limb movement only occurs distal to the moving joint, and muscle activation occurs in the muscles that cross the moving joint.  For example, during knee flexion in an open-chain exercise. , the action of the hamstrings is independent of recruitment of other hip or ankle musculature in  k
