Ballistic Stretching Ballistic stretching uses the momentum of a moving body or a limb in an attempt to force it beyond its normal range of motion. This is stretching, or warming up, by bouncing into (or out of) a stretched position, using the stretched muscles as a spring which pulls you out of the stretched position.

What Is The Best Workout For Increasing Flexibility? Many people stretch in order to warm up for a weight training session. While the intention to actually warm up is a step ahead of many, the method used in these cases does little/no good as a warm-up. Overstretching before a workout can even have negative effects, in addition to doing a very poor job as a warm-up.

The Difference Between Warm Up & Stretch There is an important difference between warm-up and stretching. If one stretches the muscles without prior warm-up, the muscles are cold and are more prone to injury, such as muscle tear or strain.

- The Purpose of Warm-Up. The main purpose of warm-up is to ready the body for the subsequent activity. It assists the heart, lungs and muscles to prepare for the intensity of exercise and to ease the body through the transition between rest to exercise. There are many forms of warm-up. Calisthenics. stretching and other forms of stationary exercise are popular.

The Effects of Temperature on Muscular Contraction Temperature. Temperature can greatly affect the ability of your muscle to contract. It is more difficult for muscle to contract in cold temperatures than in warmer conditions. Temperature affects the ease with which oxygen is released from hemoglobin. At cold temperatures, oxygen is more tightly bound to the hemoglobin and does not release as easily. This slower rate of release leads to a lower amount of oxygen available to your muscles, making contraction more difficult. You feel this as stiffness in your muscles.

- Stretching is not a legitimate means of cooling down. It is only part of the process. After you have completed your workout, the best way to reduce muscle fatigue and soreness (caused by the production of lactic acid from your maximal or near-maximal muscle exertion) is to perform a light warm-down.

- Your uterus might start contracting to build strength for the big job ahead. You might feel these warm-ups, called Braxton Hicks contractions, in your abdomen. They're usually weak and come and go unpredictably. Contact your health care provider if the contractions become painful or regular.

Warm Up and Cool Down Research work by McNair (2000) and Knudson (2001) suggests that the use of dynamic stretches-slow controlled movements through the full range of motion-are the most appropriate exercises for the warm up. By contrast, static stretches are more appropriate for the cool down.

Shivering Shivering (also called shuddering) is a bodily function in response to early hypothermia or just feeling cold in warm-blooded animals. When the core body temperature drops, the shivering reflex is triggered to maintain homeostasis. Skeletal muscles begin to shake in small movements, creating warmth by expending energy.

The Importance of Doing Warm Up Exercises before Working Out The Importance of Warm Up Exercises. Doing warm up exercises before your workout is important in many ways. A good warm up will gradually increase your heart rate, increase circulation to your muscles, tendons and ligaments, and mentally prepare you for your workout. Although warm ups and stretching generally occur in the beginning of a workout session, they are two different concepts.

You Asked: Why Should I Warm Up Before a Workout? A warm up can be a lower intensity version of the activity you're about to do, or it can be something different. A proper warm up gradually raises your heart rate and gets your muscles primed for activity. For more information, check out The Ultimate Guide to Proper Warm-Ups. Spending just a few minutes on this important component of your workout will help you perform at your best, prevent injury and make your workout experience as positive and effective as possible!

- shivering with cold image by Cherry-Merry from Fotolia.com. Shivering thermogenesis is the production of body heat generated by involuntary muscle action during shivering. All mammals and birds have a shivering response, but few reptiles are capable of shivering thermogenesis.hivering thermogenesis is used to heat the body when it becomes too cold. Shivering is usually triggered by exposure to cold environmental temperatures, but the temperature set point that triggers shivering varies among species and individuals.

3 ways your body battles the cold In a venture to bring the body's temperature back up, the body will strive to generate heat itself by allowing muscles and organs to shake within the body, more commonly known as shivering. While this method uses more energy and is quite inefficient, according to Johnson, it usually begins when skin temperatures begin to fall.

Muscle Contraction Types â Part 1 A concentric contraction is a type of muscle contraction where the length of the muscles shorten while undergoing tension. For example, when you pick up a curl bar and perform a biceps curl, the length of your biceps muscles shorten. Your hands start down by your sides, and ends with your hands up by your shoulders.

Warm Up Activities & Stretching Exercises The aim of the general warm up is simply to elevate the heart rate and respiratory rate. This in turn increases the blood flow and helps with the transportation of oxygen and nutrients to the working muscles. This also helps to increase the muscle temperature, allowing for a more effective static stretch.

Warm Up Exercises and Stretches 1.) General warm up: The general warm up should consist of a light physical activity, like walking, jogging, easy swimming, stationary bike, skipping or easy aerobics. Both the intensity and duration of the general warm up (or how hard and how long), should be governed by the fitness level of the participating athlete.

- So in warming up thoroughly, we are preparing the body and the mind for the more energetic demands to come. The cool down period of an exercise session is just as important as the warm up. The aim is to decrease the intensity of the aerobic session and to return the body to a state of rest. The cooling down has the effect of:

Medical Dictionary You may start shivering, which is an involuntary, rapid contraction of the muscles. This extra muscle activity helps generate more heat. Under normal conditions, this keeps your body temperature within a narrow, safe range.
