Strength training in the morning is just as effective as strength training in the evening

It does not matter whether you work out with weights in the morning or in the evening. Though the body's biological clock of the body makes the muscles react better to strength traininglater in the day, this effect is so small that most athletes do not have to take it into account. Australian sports scientists at Victoria University write this in a meta-study published in Chronobiology International.

Study
The researchers gathered previously published studies in which researchers had test subjects strength train both in the morning and in the evening, and then determined whether the time of training had any effect on their progression. The Australians found 11 studies they deemed worthy, compiled the results and analyzed them again.

Results
The subjects who had worked out in the morning, were able to develop a little more force in the morning than subjects had trained in the evening - but this difference was negligible.

Conversely, if the subjects had worked out in the evening, they could develop a bit more strength in the evening than subjects who had worked out in the morning. This difference was slightly greater than the above, but still small.


Strength training in the morning is just as effective as strength training in the evening



Strengh athletes who want to become stronger can just as well work out in the morning as in the evening, the researchers conclude. This also applies to muscle building, they note. The data on muscle mass are rather poor, so they were not able to enlighten their readers with fancy figures.

Conclusion

"In summary, the results presented herein confirm that, at baseline, the expression of strength in humans is greater in the evening than in the morning hours", write the Australians. "After a period of consistent training in the morning, strength levels, as observed in the morning, appear to become similar to those observed in the evening."

"By contrast, training in the evening maintains the general differences in the strength expression across different times of the day."

"Training both in the morning and in the evening hours may produce similar improvements in strength regardless of the time at which the testing sessions are conducted. This is likely given that training in the morning and in the evening hours also improves strength when assessed in a specific and in a non-training specific time of day."

"Finally, increases in muscle hypertrophy are similar."

"Therefore, individuals interested in participating in resistance exercise should choose the time of the day for training that will ultimately facilitate long-term training adherence."

"For sports coaches and trainers, it is interesting to note that after a period of training in the morning hours, strength levels in these hours appear to become similar to those observed in the evening. However, when training in the evening hours, the general difference in strength between morning and evening hours does not change."

"These findings may be of considerable value from a practical standpoint as they highlight that if the specific time of competition for an athlete is known in advance, at least some of the training sessions should be organized so that they coincide with the competition time of day (to ensure a positive time-specific performance)."

Training in the afternoon slightly more effective than in the morning
In the short term it makes no difference whether you pump iron in the morning or afternoon. But if you can choose, then probably in the long term it's better to train in the afternoon.

Bodybuilders who train in the evening grow faster
The best time to do weight training is in the evening, say Australian sports scientists who measured hormone levels in young natural power athletes.
