25/8/2015 – WARM UP ! COOL DOWN !

Warm-up is one of the most important elements of an exercise program. It is particularly important to help prevent injury. Warm-up is low-level activity, which should be completed prior to stretching and more strenuous exercise. The objective of the warm-up is to raise total body temperature and muscle temperature to prepare the entire body for vigorous activity. The warm-up period prepares the cardiovascular system, respiratory system, nervous system and the musculoskeletal system by gradually increasing the demand on those systems so that they are able to accommodate the demands of more strenuous activity.

 

A proper Warm-up serves to raise the body to a necessary work capacity.

There are two types of Warm-Up:

  1. General
  2. Sport Specific.

The purpose of the General Warm-up is to increase the functional potential of the body as a whole, whereas the purpose of the specific warm-up is to establish the relationship between the upcoming movements/workout. The Sport Specific General Warm-up utilizes low intensity movements and exercises that actually involve the body parts that will be used in the subsequent activity. The General Warm-up is effective for raising core temperature and increasing blood circulation in order to raise both the general body and the deep muscle temperatures, which in turn help to heat up the muscles, ligaments and tendons in preparation for more vigorous activity. The way that we know we have done this is by breaking a sweat. So if there is sweat we can assume that the core temperature has elevated.

 

The likelihood of injury is reduced. Athletic performance can be improved. The warm-up increases muscle efficiency, reduces potential for muscle pulls, improves reaction time and improves the speed of movement of muscled and ligaments. A proper general warm-up can also help reduce the severity of post-exercise muscle soreness. The higher temperatures and increased blood flow resulting from warm-up are important for delivery of oxygen to the muscles and for prevention of build-up of unwanted waste products which can lead to muscle soreness.

 

Duration & Intensity of Warm-up

 

It is difficult to recommend specific intensity and duration of warm-up for every person, but most research in this area suggests an increase in body and muscle temperature of approximately one to two degrees Fahrenheit to be adequate. A brisk 5-10 minute General Warm-up will generally produce sufficient results to prepare the body for more strenuous exercise. The duration and intensity of warm-up should be adjusted according to the environmental temperature and the amount of clothing worn. The higher the environmental temperature and the greater the amount of clothing, the sooner the desired body temperature is attained. It is also important to begin a major activity while still warmed-up. Ideally, the rest period should be more than a few minutes. In any case, no more than fifteen minutes should elapse. When the beneficial effect of warm-up has dissipated, the muscle temperature will have returned to pre-warm-up levels.

The Benefits of Cooling Down

KEY POINTS

A cool down should last 5-10 minutes or longer, and allowing for the gradual return of heart rate, respiratory rate, and core body temperature back to pre-exercise levels.

A cool-down is an essential recovery tool for transitioning the body from activity to a state of rest.

A well-organized cool-down may accelerate the recovery process by decreasing the effects of delayed onset muscle soreness (DOMS) and post-exercise stiffness, allowing for a more efficient exercise adaptation.

A cool-down should include flexibility and mobility exercise techniques focused on improving muscle/soft tissue elasticity, and joint mobility of all major muscles and body segments utilized during the exercise session.

 

INTRODUCTION

The practice of cooling down after exercise promotes recovery and allows for a smooth transition between physical activity and a state of rest. Just as a warm-up prepares your body for exercise, a cool-down provides an effective means for initiating the recovery process. During a bout of strenuous exercise your body goes through many stressful processes resulting in muscle and soft tissue microtrauma. A cool-down is the first step in the recovery and repair cycle. Unfortunately, many exercisers pressed to fit a workout into their busy schedules fail to recognize the benefits a cool down provides. Educating yourself about the cool-down process and the role it plays in the overall recovery scheme will enhance your exercise experience and leave you feeling rejuvenated after each and every workout.

BENEFITS

Cooling down after exercise can prevent dizziness and allow for a seamless transition to a resting state. When exercising, your muscles serve as a secondary pump assisting the heart in circulating blood to all the working areas of the body. If you go from a period of intense activity to rest, the muscles stop pumping blood and the heart must compensate and pick up the extra workload. If the heart is not capable of this, you may experience a period of dizziness or possibly even pass out. Below is a list of additional benefits a cool-down offers: Allows for a safe and gradual return of heart rate, respiration rate, and core body temperature back to pre-exercise levels.

Allows for the safe and gradual return of heart rate, respiration rate, and core body temperature back to pre-exercise levels.

Reduces the risk of post-exercise cramping or spasm.

Aids in the prevention of blood pooling, dizziness, and fainting.

Assists in the removal of waste products such as lactic acid, which can accumulate during vigorous exercise and delay recovery time.

Assists in the decrease of post-exercise stiffness and muscle soreness.

May enhance flexibility and facilitate an improvement in the length-tension relationships between muscles.

May decrease the risk of injury.

Begins the recovery process, preparing the body for the next workout.

 

COOL-DOWN – DELAYED ONSET MUSCLE SORENESS – EXERCISE ADAPTATION?

Delayed onset muscle soreness (DOMS) is the pain, muscle stiffness and/or swelling felt 24-72 hours after a bout of strenuous exercise and typically lasting 2-3 days. Although the precise cause is still unknown, it is believed that DOMS is the result of lactic acid accumulation as well as exercise or activity that produces repetitive eccentric muscle contractions, such as downhill running or resistance training. Eccentric contractions occur when an external force is applied which causes a muscle to lengthen. When stress is placed on the muscle beyond what that to which it is accustomed, small microscopic tearing and inflammation occur. It is believed that this tearing and the subsequent inflammatory response results in pain. Mild soreness can be expected and is an indication that your muscles are adapting to the exercise stimulus. An organized and well designed cool-down may reduce the effects of DOMS and is the first step in accelerating the recovery process. Returning to exercise while in the DOMS state would be uncomfortable, delay exercise adaptation, and may result in overtraining or injury.

THE COOL-DOWN EXPERIENCE

A cool-down should be enjoyable and leave you feeling refreshed. A period of light activity for 5-10 minutes after exercise, including a series of flexibility and mobility exercises, will facilitate this process. The cool- down period is the best time to perform static stretching, soft tissue techniques, and gentle mobility exercise. Focus on the major muscles and body segments utilized during the exercise session. Below are some definitions and techniques to assist you in your selection.

Stretching

Many people use the term “passive stretching” and “static stretching” interchangeably. However, there are a number of experts who make a distinction between the two.

Static stretching

Involves holding a specific joint position which lengthens its associated muscle(s) for 10-30 seconds.

Passive stretching

Is a technique during which you are relaxed and make no contribution to the range of motion. Instead, an external force is created by an outside agent, either manually or mechanically.

Self-Myofascial Release (SMR)

SMR on a foam roller offers an effective, inexpensive, and convenient way to reduce both soft tissue adhesion and scar tissue accumulation. Note that, as with stretching, foam rolling doesn’t yield measurable improvements overnight; you will need to be diligent and stick with it (although you will definitely notice acute benefits).

 

*Those with circulatory problems and chronic pain diseases (Fibromyalgia) should avoid using foam rollers.

Mobility Exercise Techniques

Acts as a foundational method for restoring joint motion. Provides enhanced nutrient flow and improves joint lubrication

CONCLUSION

Exercise is beneficial for all who participate, however, maximizing the results of your routine require a planned and carefully thought out post-exercise cool-down and recovery strategy. When cooling-down, take into consideration the frequency, intensity, time, and type (FITT Principles) of exercise activity you are participating in. These factors will influence the amount of time required for recovery. More intense activities and those lasting one hour or longer demand extended cool-down and recovery periods. Taking a few extra minutes at the end of an exercise session to cool-down properly will accelerate the recovery process, decrease the risk of injury, enhance performance, and ensure long term health and fitness success.
