ATP is available for a few seconds and then needs to be topped up. This is done by splitting creatine phosphate (creatine phosphate, or CP). Neuromuscular fatigue, as this general fatigue is officially called, is a complex process about which not everything is known yet. We can more or less distinguish the following types of fatigue, which, however, are also intertwined.Īfter you have trained a muscle to (near) failure, you have used up energy that is stored in the muscle cell. This is done according to the energy system ATP-CP . The muscle is therefore tired and needs time to recover. We call this local (also called peripheral) fatigue. If you’re training for muscle growth, getting enough rest between sets is essential for the quality of those sets. That quality is determined by the amount of mechanical tension you create through the stimulating repetitions just before muscle failure.Īfter completing the last rep, just before or even all the way to muscle failure, you experience an overall fatigue. You don’t have to think about picking up that dumbbell and barbell again and doing so many repetitions again. It is not only the trained muscle that is fatigued. Mind you, muscle failure means that the muscle gives up: there is local fatigue (see next paragraph). If you have to stop a set due to some other type of fatigue, such as cardiovascular, you may still be a long way from muscle failure. Even then you ‘miss’ some or all of the stimulating repetitions. So let’s say you do a set of ten reps to near muscle failure (ie with 1 Rep In Reserve). Reps 6-10 are about those five stimulating reps. Then if you hardly rest, say only ten seconds, you may only be able to do two repetitions to near-muscle failure in your next set. That is too little to count as a full set. The total number of reps of the set, in theory, doesn’t matter. If you’re using a light weight, you may need fifteen reps to get to the five stimulative ones. Use a very heavy weight and you will almost immediately reach those five stimulating repetitions. Which is not to say that the repetitions before those five aren’t stimulating at all, but that aside. That is, you do five reps that are close to muscle failure, also known as the effective reps. After all, with those repetitions most motor units in the muscle are addressed, which creates the most mechanical tension. Mechanical tension is the main training stimulus for muscle growth. If you’re training for muscle growth, each set should give you about five reps that are stimulative. In short, the function of rest times between sets is that you can do sets that are effective enough for your training goal. WHAT IS THE FUNCTION OF RESTING BETWEEN SETS? If you train purely for strength gain instead of muscle growth, rest for 3 to 5 minutes, depending on the intensity of the set. Beginners are likely to arrive with shorter breaks. Shorter rest periods may not be optimal for muscle growth, but they can provide other benefits, such as improving fitness and burning more fat. The choice for more metabolic strength training, with short or even no rest breaks, therefore depends on the training goal(s).ħ. If you find it difficult to feel when you are completely ready for your next set, use as a guideline 1-2 minutes for isolating exercises, 2-3 for most compound exercises and 3-5 for squats and deadlifts. Only start your next set when you feel completely ready physically and mentally: you must be able to use all your available strength and achieve a good mind-muscle connection. To this end, all fatigue from the previous set must be sufficiently resolved: the local fatigue (in both the target and auxiliary muscles), the central fatigue and the cardiovascular fatigue.ĥ. Very short rest is therefore no use: it comes at the expense of the amount of stimulating repetitions you can do in the next set. Several studies show that you build more or faster muscle mass when you use longer rest periods between sets.Ĥ. Aim to do about five stimulating reps in each set. If you do too few – because you only get a few reps, or because you stay too far away from muscle failure – you have to do more sets to compensate.ģ. If you’re training for muscle growth, getting enough rest between sets is essential for the quality of those sets. That quality is determined by the amount of mechanical tension you create through especially the stimulating repetitions just before muscle failure.Ģ.
