August 2. 0, 2. 01. Below is an excerpt from my book, Strong Sculpted that discusses my current approach to warming up prior to resistance training. I neglected to include a chapter on the topic in my book, M. A. X. Muscle Plan so for those following this program, the same info applies.

The warm up contains two basic components a general warm up and a specific warm up. Heres what you need to know about each component for a safe, effective workout. Clinical Trial Hierarchy Of Evidence Sackett' title='Clinical Trial Hierarchy Of Evidence Sackett' />General Warm Up. The general warm up is a brief bout of low intensity, large musclegroup, aerobic type exercise. The objective is to elevate your core temperature and increase blood flow, which in turn enhances the speed of nerve impulses, increases nutrient delivery to working muscles and the removal of waste by products, and facilitates oxygen release from hemoglobin and myoglobin. A direct correlation exists between muscle temperature and exercise performance when a muscle is warm, it can achieve a better contraction. As a rule, the higher a muscles temperature is within a safe physiological range, the better its contractility. And because better contractility translates into greater force production, youll ultimately achieve better muscular development. Whats more, an elevated core temperature diminishes a joints resistance to flow viscosity. This is accomplished via the uptake of synovial fluid, which is secreted from the synovial membrane to lubricate the joint. Coverage of more than 90 per cent was achieved, with a dramatic effect on all three clusters of cases were often importations. Immunisation against a common. Evidencebased medicine attempts to objectively evaluate the quality of clinical research by critically assessing techniques reported by researchers in their. Evidencebased practice is critical to undergraduate and graduate nursing education. Florence Nightingale was a pioneer of evidencebased practice.

Better yet, these factors combine to reduce the risk of a training related injury. Suffice it to say that the general warm up is an important part of a workout. Virtually any cardiorespiratory activity can be used for the general warm up. Exercises on equipment such as stationary bikes, stair climbers, and treadmills are fine choices, as are most calisthenic type exercises e. Choose whatever activity you desire as long as the basic objective is met. The intensity for the general warm up should be low. To estimate intensity of training, I like to use a rating of perceived exertion RPE scale. My preference is the category ratio RPE scale, which grades perceived effort on a scale from 0 to 1. Aim for an RPE of around 5, which for most people is a moderate walk or slow jog. You can use the talk test as an intensity gauge. With this method, you base intensity on your ability to carry on a conversation if you have to pause to take a breath while speaking a sentence, youre working too hard. Philosophy of Medicine. While philosophy and medicine, beginning with the ancient Greeks, enjoyed a long history of mutually beneficial interactions, the. The Challenges of Implementing Evidence Based Practice Ethical Considerations in Practice, Education, Policy, and Research. Five to ten minutes is all you need for the general warm upjust enough to break a light sweat. Your resources should not be taxed, nor should you feel tired or out of breath either during or after performance. If so, cut back on the intensity. Remember, the goal here is merely to warm your body tissues and accelerate blood flownot to achieve cardiorespiratory benefits or reduce body fat. Specific Warm Up. The specific warm up can be considered an extension of the general warm up. By using exercises that are similar to the activities in the workout, the specific warm up enhances neuromuscular efficiency for the exercise you are about to perform. In essence, your body gets to rehearse the movements before you perform them at a high level of intensity, translating into better performance during your working sets. To optimize transfer of training, the exercises in the specific warm up should mimic the movements in the workout as closely as possible. For example, if you are going to perform a bench press, the specific warm up would ideally include light sets of bench presses. A viable alternative would be to perform push ups because the movement pattern is similar to that of a bench press, although the specificity, and thus transfer, would not be as great as with light sets of the given movement. Always stop specific warm up sets well short of fatigue. The object is not to fatigue your muscles, but rather to get a feel for the exercise so that youre physically and mentally prepared for intense training. The specific warm up is particularly important when training in low repetition ranges five reps or fewer. I recommend at least a couple of specific warm up sets per exercise during low rep training. As a general rule, the first set should be performed at 4. RM and the second set, at 6. RM. Six to eight reps is all you need in these setsany more is superfluous and potentially counterproductive. Following the specific warm up, you should be ready and able to plow into your working sets. The need for specific warm up sets in medium to high rep range training remains questionable. I recently collaborated on a study that investigated the effects of a warm up on the ability to carry out repetitions to failure at 8. RM a weight that allows performance of about eight reps in the squat, bench press, and arm curl Ribeiro et al., 2. The verdict Warming up showed no beneficial effects on the number of repetitions performed in medium to high rep range training nor in a measure called the fatigue index, which is a formula that assesses the decline in the number of repetitions across the first and last sets of each exercise. At face value these results suggest that warming up is pretty much useless prior to submaximal resistance training. Despite the currently held belief that a specific warm up enhances exercise performance, no benefits were seen when compared to no warm up at all. Intuitively, this seems to make sense given that the initial repetitions of a submaximal lifts are in effect their own specific warm up, and increasing core temperature might be superfluous from a performance standpoint when multiple reps are performed. It should be noted, however, that we found a slight advantage to performing a specific warm up prior to the squat although results did not rise to statistical significance the specific warm up prior to the biceps curl seemed to be somewhat detrimental. Thus, more complex movement patterns seem to benefit from the practice effect of a specific warm up, although this would be of no value prior to simple exercises. Taking the evidence into account, heres my recommendation When performing medium rep range work 8 to 1. One set at about 5. RM is all you need to obtain any potential benefits. Specific warm up sets are not necessary when training with high reps 1. In this instance, because youre already using light weights, the initial repetitions of each working set serve as rehearsal reps. Whats more, performance of warm up sets is counterproductive to the goal of maximizing training density to bring about desired metabolic adaptations. What About StretchingStatic stretching is commonly included as part of a prelifting warm up. This method of flexibility training involves moving a joint through its range of motion to the point where you feel slight discomfort, and then holding the position for a period of time generally about 3. Most protocols involve performing several sets of static holds and then moving on to stretches for other muscles. Its commonly believed that the addition of stretches to a warm up further reduces injury risk while enhancing physical performance. In recent years, however, the benefits of preexercise static stretching have come under scrutiny.
