Safety for any Physical Activity
Maintaining proper form
When the exercise becomes difficult towards the end of a set, there is a temptation to cheat, i.e., to use poor form to recruit other muscle groups to assist the effort. This may shift the effort to weaker muscles that cannot handle the weight. For example, the squat and the dead lift are used to exercise the largest muscles in the body—the leg and buttock muscles—so they require substantial weight. Beginners are tempted to round their back while performing these exercises. The relaxation of the spinal erectors which allows the lower back to round can cause shearing in the vertebrae of the lumbar spine, potentially damaging the spinal discs.
Stretching and warm-up
Weight trainers commonly spend 5 to 20 minutes warming up their muscles before starting a workout. It’s common to stretch the entire body to increase overall flexibility; however, many people stretch just the area being worked that day.
Warm up sets are also important. For example the same lifter working on his chest would also be advised to complete at least two warm up sets prior to hitting his “core tonnage.” Core tonnage refers to the heavier lifts that actually strain your muscles. For example if the lifter’s main sets were at 205 lbs, 225 lbs and 235 lbs on the bench, then a warmup of 5 reps of 135 and 5 reps of 185 would be advisable. When properly warmed up the lifter will then have more strength and stamina since the blood has begun to flow to the muscle groups.
Breathing
Breathing shallowly or holding one’s breath while working out limits the oxygen supply to the muscles and the brain, decreasing performance and, under extreme stress, risking a black-out or a stroke by aneurysm. Some people advise weight trainers to conscientiously “exhale on effort” and to inhale when lowering the weight. This technique ensures that the trainer breathes through the most difficult part of the exercise, where one would reflexively hold one’s breath.
Other coaches advise trainees to perform the valsalva maneuver during exercises which place a load on the spine, since the risk of a stroke by aneurysm is astronomically lower than the risk of an orthopedic injury caused by inadequate rigidity of the torso.
Hydration
As with other sports, weight trainers should avoid dehydration throughout the workout by drinking sufficient water, even while not thirsty. Unless you are sweating to an extreme degree, being thirsty is not a sign that you have already become dehydrated. However, if an athlete relies on thirst alone for when and how much to drink, it may lead to their becoming dehydrated. This is particularly true in hot environments, or for those older than 65.
Some athletic trainers advise athletes to drink about 7 imperial fluid ounces (2.0 dL) every 15 minutes while exercising, and about 80 imperial fluid ounces (2.3 L) throughout the day.
However, a much more accurate determination of how much fluid is necessary can be made by performing appropriate weight measurements before and after a typical exercise session, to determine how much fluid is lost during the workout. The greatest source of fluid loss during exercise is through perspiration, but as long as your fluid intake is roughly equivalent to your rate of perspiration, hydration levels will be maintained.
Under most circumstances, sports drinks do not offer a physiological benefit over water during weight training. However, high-intensity exercise for a continuous duration of at least one hour may require the replenishment of electrolytes which a sports drink may provide. Some may maintain that Energy drinks, such as Red Bull that contain caffeine, improve performance in weight training and other physical exercise, but in fact, these energy drinks can cause dehydration, tremors, heat stroke, and heart attack when consumed in excess. ‘Sports drinks’ that contain simple carbohydrates & water do not cause ill effects.
However, it is also important not to consume too much water in a short time, as this can lead to water intoxication and other electrolyte disturbances which in turn can lead to nausea, vomiting, convulsions, brain swelling, unconsciousness and possibly death in extreme cases.
Insufficient hydration may cause lethargy, soreness or muscle cramps.The urine of well-hydrated persons should be nearly colorless, while an intense yellow color is normally a sign of insufficient hydration.
Avoiding pain
An exercise should be halted if marked or sudden pain is felt, to prevent further injury. However, not all discomfort indicates injury. Weight training exercises are brief but very intense, and many people are unaccustomed to this level of effort. The expression “no pain, no gain” refers to working through the discomfort expected from such vigorous effort, rather than to willfully ignore extreme pain, which may indicate serious soft tissue injuries.
Discomfort can arise from other factors. Individuals who perform large numbers of repetitions, sets, and exercises for each muscle group may experience a burning sensation in their muscles. These individuals may also experience a swelling sensation in their muscles from increased blood flow (the “pump”). True muscle fatigue is experienced as a marked and uncontrollable loss of strength in a muscle, arising from the nervous system (motor unit) rather than from the muscle fibers themselves. Extreme neural fatigue can be experienced as temporary muscle failure. Some weight training programs actively seek temporary muscle failure; evidence to support this type of training is mixed at best. Irrespective of their program, however, most athletes engaged in high-intensity weight training will experience muscle failure during their regimens.
Beginners are advised to build up slowly to a weight training program. Untrained individuals may have some muscles that are comparatively stronger than others. An injury can result if, in a particular exercise, the primary muscle is stronger than its stabilizing muscles. Building up slowly allows muscles time to develop appropriate strengths relative to each other. This can also help to minimize delayed onset muscle soreness. A sudden start to an intense program can cause significant muscular soreness. Unexercised muscles contain cross-linkages that are torn during intense exercise.
