Set and repetition schemes that are structured to produce high levels of fatigue may be detrimental for power development due to lower velocities and lower rates of force production at the end of a set. The selection of appropriate rest intervals becomes crucial to maintain high velocity, rate of force production, and power throughout a set. For advanced lifters that possess high levels of strength, the most effective strategy to increase power might be to focus on lifts that involve higher velocities and rates of force production. ≤ 250 ms) that the rate of force production may eventually become more important than absolute force production ( 7). This is because sports skills are performed so rapidly (i.e. However, continual increases in strength over time may not lead to increases in power. Increases in either of these components may increase power output. Muscular power represents a combination of strength and the speed of muscle action ( 3,4).

A brief review: Factors affecting the length of the rest interval between resistance exercise sets. Figure 1:įactors affecting the length of the rest interval. The goal of this article will be to take several research examples and determine how the findings can be applied in a practical manner. Therefore, the purpose of this article will be to discuss some of these factors in the context of different training goals that include: power, strength, hypertrophy, and muscular endurance. However, other factors related to the workout or individual characteristics may shorten or lengthen the rest interval ( 23). The central factor that determines the baseline prescription of the rest interval might be the training goal (3, 4 see Figure 1). These general recommendations provide an important baseline for resistance exercise prescription, but they also represent relatively broad ranges that may vary throughout a training cycle ( 23). Conversely, shorter rest intervals of 30 seconds to 90 seconds have been recommended for muscular hypertrophy and less than 30 seconds for muscular endurance. For example, when training for muscular power and strength, longer rest intervals of 2 to 5 minutes have been recommended between sets.

To help athletes achieve maximal results, the rest between sets must be considered just as important as any other component within a resistance exercise program.Ī commonly used text on resistance exercise has made some general recommendations that are based on different training goals ( 3,4).

A problem exists when idle conversation extends far beyond when full recovery has taken place. The next set might be performed when the athlete feels ready or in some unfortunate cases when two athletes have a break in their conversation. A rest period between sets is typically acknowledged, but might be undertaken carelessly or without thought concerning the specific length of time, or the impact of the time between sets on workout performance and subsequent physiological adaptations. Since blood flow to the muscle is occluded at intensities as low as 20% of maximal strength, a rest period is essential to reestablish intramuscular blood flow and oxygen delivery that allows for the replenishment of phosphocreatine stores, restoration of intramuscular pH, removal of metabolic end products, and return of muscle membrane potential to resting levels ( 10,22,23).Ī workout is commonly prescribed simply based on the load lifted per set, the number of sets per exercise, and the number repetitions per set ( 3,4). Most resistance exercise programs are conducted at intensities that range from 30% to 100% of maximal strength ( 3,4). The time to fatigue is dependent on the training intensity or percentage of maximal strength that is lifted. Because resistance exercise emphasizes anaerobic metabolism, the muscles reach fatigue relatively quickly. However, relatively few studies have been conducted to determine the effect of different rest intervals between sets ( 22,23).Ī certain amount of rest between sets is essential.

Several studies have compared neuromuscular adaptations resulting from different volumes of training (i.e., single versus multiple sets) ( 17).

The most common component and most frequently studied is the workout volume ( 3,4). Several components make up the structure of a resistance exercise program. Part of what makes resistance exercise so popular and effective is the seemingly endless selection and variation of exercises. Resistance exercise has become very popular and is now considered an essential component of every athletes conditioning program.
