![]() ![]() However, we only have this system for around 10-15 seconds of maximum output. So, in the case of heavy lifting (think 1-3 rep max attempts), ATP-PC is utilized to generate immediate power. ![]() The type of activity is what dictates which system(s) are used. All three systems are readily available and ‘initiated’ at the outset of any activity. Now, there are three energy systems that produce ATP: ATP-PC (high power, short duration), glycolytic (moderate power/short duration), and oxidative (low power/long duration). With that being said, the amount of rest taken in between sets is directly related to how much energy will be available to the muscles for the following set. Now, there is a lot of science that goes into understanding ATP, but the simplified version for the understanding of this piece is that the body has a limited supply of ATP, and it must be replenished for work to continue. The body’s primary energy resource for ANY muscle contraction/force exertion is from a molecule called adenosine triphosphate (ATP). But what is that optimum time? And why is it so important that we use it to recover? Most people will have an internal clock in their bodies that determines when they’ve had enough rest and their muscles are ready to work against a load. It’s not uncommon for coaches to have you pair up with a fellow athlete of similar size and strength to make the weight transitions easier. volume and intensity), the amount of rest between sets can influence the efficiency, safety and ultimate effectiveness of a strength training programme.On heavy lifting days, it’s wise to take your time between each set. When prescribed appropriately with other important prescriptive variables (i.e. ![]() In summary, the rest interval between sets is an important variable that should receive more attention in resistance exercise prescription. Both of these findings indirectly demonstrated the benefits of utilizing short rest intervals for gains in muscular endurance. 20 seconds to 1 minute) resulted in higher repetition velocities during repeated submaximal muscle actions and also greater total torque during a high-intensity cycle test. Finally, the research on rest interval length in relation to chronic muscular endurance adaptations is less clear. When the training goal is muscular hypertrophy, the combination of moderate-intensity sets with short rest intervals of 30-60 seconds might be most effective due to greater acute levels of growth hormone during such workouts. Conversely, some experiments have demonstrated that when testing maximal strength, 1-minute rest intervals might be sufficient between repeated attempts however, from a psychological and physiological standpoint, the inclusion of 3- to 5-minute rest intervals might be safer and more reliable. Similarly, higher levels of muscular power were demonstrated over multiple sets with 3 or 5 minutes versus 1 minute of rest between sets. Furthermore, in terms of chronic adaptations, resting 3-5 minutes between sets produced greater increases in absolute strength, due to higher intensities and volumes of training. In terms of acute responses, a key finding was that when training with loads between 50% and 90% of one repetition maximum, 3-5 minutes' rest between sets allowed for greater repetitions over multiple sets. The 35 studies reviewed examined both acute responses and chronic adaptations, with rest interval length as the experimental variable. The Scielo, Science Citation Index, National Library of Medicine, MEDLINE, Scopus, Sport Discus and CINAHL databases were used to locate previous original scientific investigations. absolute muscular strength, endurance, hypertrophy and muscular power). The purpose of this review is to analyse and discuss the rest interval between sets for targeting specific training outcomes (e.g. Research has indicated that the rest interval between sets is an important variable that affects both acute responses and chronic adaptations to resistance exercise programmes. For efficient, safe and effective training, it is of utmost importance to understand the interaction among training variables, which might include the intensity, number of sets, rest interval between sets, exercise modality and velocity of muscle action. Strength training has become one of the most popular physical activities for increasing characteristics such as absolute muscular strength, endurance, hypertrophy and muscular power. ![]()
