An 8-wk progressive resistance training program for the lower extremity was performed twice a week to investigate the time course for skeletal muscle adaptations in men and women. Maximal dynamic strength was tested biweekly. Muscle biopsies were extracted at the beginning and every 2 wk of the study from resistance-trained and from nontrained (control) subjects. The muscle samples were analyzed for fiber type composition, cross-sectional area, and myosin heavy chain content. In addition… 

Figures and Tables from this paper

Changes in muscle size and MHC composition in response to resistance exercise with heavy and light loading intensity.

LL resistance training was sufficient to induce a small but significant muscle hypertrophy in healthy young men, however, LL resistanceTraining was inferior to HL training in evoking adaptive changes in muscle size and contractile strength and was insufficient to induce changes in MHC composition.

Effects of sprint cycle training on human skeletal muscle.

Although a trend was found for a decrease in the percentage of type IIb fibers, high-intensity sprint cycle training caused no significant changes in the fiber type distribution or cross-sectional area and data appear to support previous investigations that have suggested exercise-induced adaptations within the fast fiber population (IIb-->IIa).

Muscle hypertrophy, hormonal adaptations and strength development during strength training in strength-trained and untrained men

The correlations between T and the changes in isometric strength and in muscle CSA suggest that both serum basal testosterone concentrations and training-induced changes in acute testosterone responses may be important factors for strength development and muscle hypertrophy.

Early skeletal muscle hypertrophy and architectural changes in response to high-intensity resistance training.

It is shown for the first time that changes in muscle size are detectable after only 3 wk of RT and that remodeling of muscle architecture precedes gains in muscle CSA, which seems to contribute to strength gains earlier than previously reported.

The effects of short-term resistance training on endocrine function in men and women

Data illustrate that untrained individuals may exhibit early-phase endocrine adaptations during a resistance training program and may influence and help to mediate other adaptations in the nervous system and muscle fibers, which have been shown to be very responsive in the early phase of strength adaptations with resistance training.

Effects of heavy-resistance training on hormonal response patterns in younger vs. older men.

The data indicate that older men do respond with an enhanced hormonal profile in the early phase of a resistance training program, but the response is different from that of younger men.

Muscle strength and hypertrophy occur independently of protein supplementation during short-term resistance training in untrained men.

It is suggested that short-term resistance training augments muscle strength and size in previously untrained men with no additive benefit from postexercise protein supplementation.

Does Sex Affect the Muscle Strength and Regional Lean Tissue Mass Response to Resistance Training in Older Adults

It is suggested that well-functioning older men and women show similar gains in muscle strength and whole body and regional lean tissue mass indicating comparable neuromuscular and anabolic responses accompanying resistance training.

Muscular adaptation and strength during the early phase of eccentric training: influence of the training frequency.

The results suggest that, compared with group A, additional eccentric exercise in group B is the essential basis for the increase in muscle strength during the early phase of eccentric training without further benefits for muscular adaptation.

Impact of resistance exercise during bed rest on skeletal muscle sarcopenia and myosin isoform distribution.

Results indicate that REx prevented BRU-induced myofiber atrophy and also maintained training-specific strength, and may prove useful in prescribing exercise for astronauts in microgravity.



Strength and skeletal muscle adaptations in heavy-resistance-trained women after detraining and retraining.

The data suggest that rapid muscular adaptations occur as a result of strength training in previously trained as well as non-previously trained women.

Muscle hypertrophy response to resistance training in older women.

It is concluded that a program of resistance exercise can be safely carried out by elderly women, such a program significantly increases muscle strength, and such gains are due, at least in part, to muscle hypertrophy.

Influence of eccentric actions on skeletal muscle adaptations to resistance training.

Three different training regimens were performed to study the influence of eccentric muscle actions on skeletal muscle adaptive responses to heavy resistance exercise, and changes in fibre type composition and capillary frequency were manifest after detraining.

Muscle hypertrophy in men and women.

It is widely believed that women experience less skeletal muscle hypertrophy consequent to heavy-resistance training than men, but this hypothesis was tested using both traditional indirect indicators as well as a direct measure of muscle size using computed tomography scanning.

Changes in human muscle protein synthesis after resistance exercise.

The results indicate that a single bout of heavy resistance exercise can increase biceps MPS for up to 24 h postexercise, and these increases appear to be due to changes in posttranscriptional events.

Endogenous anabolic hormonal and growth factor responses to heavy resistance exercise in males and females.

Growth hormone increases in both males and females following the P-2 HREP were significantly greater at all time points than corresponding P-1 values; Females exhibited significantly higher pre-exercise hGH levels compared to males.

Skeletal muscle myosin heavy chain composition and resistance training.

The results suggest that heavy resistance training alters MHC composition in human skeletal muscle, presumably reflecting a change in genetic expression.

Physiological changes in skeletal muscle as a result of strength training.

For the athlete or patient hoping to increase muscle size by weight training the best combination of intensity, frequency and type of exercise still remains a matter of individual choice rather than a scientific certainty.

Contrasts in muscle and myofibers of elite male and female bodybuilders.

Biceps CSA was positively correlated to fiber CSA and fiber number, suggesting that adaptations to resistance training may be complex and involve fiber hypertrophy and Fiber number (e.g., proliferation).

A morphological/biochemical study on the actions of corticosteroids on rat skeletal muscle

The hormones′ atrophic effects on skeletal muscle primarily arose from the corticosteroid's ability to inhibit protein synthesis, via decreases in the muscles′ ribosomal capacities.
