Microtraumas can significantly reduce strength in the long
term. For example, data from Peake et al. (2017) that, as a result of
microtraumas, the strength level of the corresponding muscles was approx. 40%
below the starting level even after five days of regeneration time. The extent
to which a training stimulus causes muscle injuries does not only depend on
external factors, but is also influenced by individual factors of the person
exercising. Older people in particular are often affected by training-related
micro-injuries. In addition to age, certain genetic predispositions also seem
to influence susceptibility to muscle damage (Baumert et al. 2016). bolts
Are muscle injuries a prerequisite
for muscle growth?
A large number of current scientific publications dealt with
the question under which conditions microtraumas occur during strength training
and to what extent they represent a condition for hypertrophy effects. Damas et
al. (2016) found, for example, an increased protein synthesis rate as a result
of microtraumas, but no muscle growth. Rather, it appears that the newly formed
protein is used to repair damaged tissue and not to rebuild contractile units. fashionglee
In another publication, the authors came to the tophealthfitnesstips conclusion
that micro-injuries occur less and less with increasing training experience.
Despite the lack of muscle damage, the proportion of newly formed muscle fibers
increases, especially in advanced exercisers (Damas et al. 2018). The authors
therefore conclude that muscle damage is not a prerequisite for muscle growth
in the long termrepresent. Rather, they are a reaction to an unfamiliar
stimulus, which primarily triggers muscle repair and not muscle growth.
Although protein synthesis is increased during repair processes, these
processes are not responsible for muscle growth superhealthiness and increased resilience. If an
objective enlargement of the muscle cross-section is achieved in the early
training phases, then swelling and water retention in the muscle cell are
primarily responsible. Flann et al. (2011) were able to show that eccentric
training causes more muscle damage in beginners than in advanced users, but
that muscle growth was equally pronounced in both groups. When training with
the aim of causing as much muscle damage as possible, The sentences are often
taken to the point of muscle failure or even beyond using intensity techniques.
A review by Grgic et al. (2021) compared the different effects of training to
muscle failure and training without muscle failure. No benefits from training
to muscle failure in terms of increasing strength or hypertrophy were found. redditbooks
