The problem Of muscle hypertrophy: Revisited

In this paper we revisit a topic originally discussed in 1955, namely the lack of direct evidence that muscle hypertrophy from exercise plays an important role in increasing strength. To this day, long‐term adaptations in strength are thought to be primarily contingent on changes in muscle size. Given this assumption, there has been considerable attention placed on programs designed to allow for maximization of both muscle size and strength. However, the conclusion that a change in muscle size…

Muscle hypertrophy and muscle strength: dependent or independent variables? A provocative review
- BiologyEuropean journal of translational myology
- 2020
A number of studies show a clear dissociation with increase of muscle size with no change or even decrease in strength and, vice versa, increase in strength without increase in size.

The results support the hypothesis that the neural adaptations play a large role in increasing isotonic whole muscle strength, but also demonstrate that an improvement in specific tension of type 1 muscle fibers is present.

Hypertrophy can be operationally defined as an increase in the axial cross-sectional area of a muscle fiber or whole muscle, and is due to increases in the size of pre-existing muscle fibers.…
Muscle growth: To infinity and beyond?
- BiologyMuscle & nerve
- 2017
The available studies indicate that the muscle growth response will plateau, and additional growth is not likely to occur appreciably beyond this initial plateau, however, the current study durations are a limitation.
Muscle size and strength: another study not designed to answer the question
- PsychologyEuropean Journal of Applied Physiology
- 2017
In conclusion, analyses like these provide little information to explain the true role of exercise-induced muscle growth as it relates to exerciseinduced muscle strength, and it is suggested that this question is best answered though study design rather than retrospective correlations.
The contraction history of the muscle and strength change: lessons learned from unilateral training models
- PsychologyPhysiological measurement

Ways to test the idea that strength change may be dictated by the contraction history of the muscle are discussed, of importance among injurious populations undergoing rehabilitation, seeking to find the most efficacious exercise regimens.
Causal Mediation Analysis Could Resolve Whether Training-Induced Increases in Muscle Strength are Mediated by Muscle Hypertrophy

Here, resistance training researchers are introduced to causal mediation analysis and it is recommended that it be used to resolve the current debate on hypertrophy.

Establishing a high baseline of strength earlier in life may have long-term implications related to mortality and disease and there may be critical periods during growth/development during which individuals can establish a higher baseline.

Skeletal Muscle Hypertrophy: How important is Exercise Intensity?
- Education
- 2012
This manuscript will review recent acute and chronic data which suggests that exercise intensity may be playing less of a role with skeletal muscle hypertrophy than previously thought.
Resistance exercise load does not determine training-mediated hypertrophic gains in young men.
- MedicineJournal of applied physiology
- 2012
A lower load lifting to failure resulted in similar hypertrophy as a heavy load lifted to failure, and there was no correlation between phosphorylation of any signaling protein andhypertrophy.
The contribution of muscle hypertrophy to strength changes following resistance training
- Biology, MedicineEuropean Journal of Applied Physiology
- 2014
It is shown for the first time that muscle hypertrophy explains a significant proportion of the inter-individual variability in isometric and isoinertial strength gains following 12-week elbow flexor RT in healthy young men.
Neural factors versus hypertrophy in the time course of muscle strength gain.
- MedicineAmerican journal of physical medicine
- 1979
The results indicated that neural factors accounted for the larger proportion of the initial strength increment and thereafter both neural factors andhypertrophy took part in the further increase in strength, with hypertrophy becoming the dominant factor after the first 3 to 5 weeks.

Elevations in ostensibly anabolic hormones with resistance exercise enhance neither training-induced muscle hypertrophy nor strength of the elbow flexors.

- 2010
It is concluded that exposure of loaded muscle to acute exercise-induced elevations in endogenous anabolic hormones enhances neither muscle hypertrophy nor strength with resistance training in young men.

The muscle size and strength responses varied extensively between the subjects regardless of subject’s age and sex, and whether these changes are associated with functional capacity and metabolic health improvements due to RT requires further studies.

The results indicate that elderly men lose some muscle strength following short-term detraining, but that only a brief period of retraining suffices to regain maximal strength.
Exercise dosing to retain resistance training adaptations in young and older adults.
- PsychologyMedicine and science in sports and exercise

It is concluded that older adults require a higher dose of weekly loading than the young to maintain myofiber hypertrophy attained during a progressive RT program, yet gains in specific strength among older adults were well preserved and remained at or above levels of the untrained young.
Neither load nor systemic hormones determine resistance training-mediated hypertrophy or strength gains in resistance-trained young men

Load, when exercises are performed to volitional failure, does not dictate hypertrophy or, for the most part, strength gains in resistance-trained individuals.
