Prior to the exercise training session it is important to take time to warm-up effectively. The effects of warm-up have been well studied and although the literature is not in complete accord, particularly regarding the effect upon performance, some type of warm-up is recommended almost universally. Physiologically, the effect of this preparatory movement is to increase circulation and to elevate body temperature. As muscle temperature rises, viscosity is reduced and the efficiency of muscle contraction is increased. Warm-up also reduces the potential for muscle pulls and skeletal muscular injury. In addition, the warm-up routine should concentrate upon muscle groups in which specific weaknesses have been identified.
Exercises for the lower back are helpful in alleviating back problems, the most common disabling orthopedic problem in adults. This might be attributed to increased myocardial demands due to heart rate increasing more rapidly than oxygen is supplied and could precipitate angina pectoris or even a myocardial infarct. The value of warm-up therefore, has implications for preventing myocardial damage as well skeletal muscular injury.
At the conclusion of the exercise session it is important to taper off gradually and not stop abruptly...
