Usually for muscles exercise one widely accepted concept on timing is that the lifting should be under full muscular control, the pause should be temporarily, and then the lowering again under full muscular control. For those who are seeking a higher result than average people a different system would be valid in many situations.
Many have overlooked the concept of timing during exercise, it is believed that timing is only important in aerobics and not weightlifting, but this is a real misconception. Altering the tempo of your muscles exercise routine is very important, for example in some occasions slow training is ideal and gives better results although on other occasions it is better to train fast, it all depends from the individuals and the results wanted.
One thing we all know is that the human body adapts to anything with ease and acts in response to different variables, so by changing the speed of exercise the body will adopt to these alterations. Speed of muscles exercise is extremely important when trying to achieve maximum results. One of the often-neglected aspects of speed is the pause, for example for bench-pressing it has been shown that a pause of four seconds while the muscle is contracted has an improved effect in muscle power.
In order to develop maximum strength research shows that slow-speed lifting done with heavy weights has a distinct advantage over high-speed lifting. By slowing down the movement there is an increase in duration of the stimulus and the level of tension on the muscle; this increases the development of the muscle muss. Research shows that varying the speed of muscles exercise instead of keeping it constant has a greater overall impact.
One thing to bear in mind when altering the speed of muscles exercise is that only athletes that have a solid base of maximum strength should apply this type of technique, at the beginning it is better to perform slowly and develop the muscles before starting to use advanced techniques. For bodybuilders though it is safe and advisable to alter the speed of training to create maximum adaptation. Fact remains that slow speed muscles exercise make the muscle work harder but at the same time slow speed muscles exercise should not be the only way to exercise as muscle requires a variety of stimuli for optimal growth.
Another important muscles exercise principal related to timing to understand is “Rest Intervals”, and that there is an inverse relationship between rest and reps: The more the reps, the lighter the weight and the smaller the rest. It seams though that the nervous system cells take longer to recover then muscle cells, meaning that the nervous system is not fully recovered to effectively activate the muscle fibres accountable for growth. Counting repetitions for maximum muscles exercise results is important but is also important to know how long you rest between exercises, hence calculating how long it takes for a complete set
