Some believe that the effect of resistance exercises does not last long, and that interruption for a few weeks may lead to muscle mass loss, which raises anxiety in many. A recent study showed that this anxiety is misplaced, as it proved that the effects of resistance exercises remain in the muscles for more than two months, and that restoring strength and muscle mass is fast when returning to exercise after interruption.
The study was conducted by researchers from the University of Journal of Physiology on April 4, and the Yurrick Alert website was written.
This study shows that resistance exercises lead to changes in muscle proteins, and these changes continue even after stopping the exercise, indicating that there is a kind of memory in the muscles that helps them to maintain the benefits of exercise.
Exercise leaves its mark in muscle proteins
Researchers have studied changes in muscle proteins on two groups of healthy people who have never practiced resistance exercises regularly. The first group underwent a 10 -week resistance training, then stopped exercise for 10 weeks, followed by an additional 10 -week training period. As for the second group, she did not exercise during the first ten weeks, then started a 20 -week training program.
The results of the study indicated that resistance exercises make clear changes in muscle protein levels, and that some of these changes continue even after stopping training for two and a half months, indicating the presence of a “protein memory” in the muscles that help to restore strength and muscle mass quickly when returning to exercise.
The results revealed two types of changes in muscle proteins:
- The first style: proteins stimulated as a result of the training, then returned to their original condition during the stoppage period, then rose again after re -training. These proteins included those associated with air metabolism (which use oxygen in the energy production process).
- The second pattern: Proteins whose quantity increased during training and remained high even after stopping the training. Among these proteins, such as Calpain-2, which was recently identified as genes associated with what is known as “genetic muscle memory”.
“We have now shown for the first time that the muscles remember previous resistance training at the level of proteins for a period of not less than two and a half months,” says Professor Yuha Hochi of the College of Sports and Health Sciences, the Music Nerve Research Center, the University of Yuvasco, and the researcher participating in this study.
“Therefore, even if the muscles gradually return to their original size after a long interruption period, the effect of the previous exercise remains in it, which makes it easy to resume the exercise again,” added Holesi.
