Article Synopsis
- The study examined the links between androgen and estrogen receptor content, as well as fiber capillarization, and muscle growth in response to resistance training in both male and female novices over 10 weeks.
- Results showed a significant increase in vastus lateralis muscle volume, but no substantial changes in individual muscle fiber sizes were observed, indicating high variability in hypertrophy outcomes among participants.
- The increase in estrogen receptor α (ERα) was positively associated with changes in fiber size, suggesting that both ERα levels and initial capillarization might influence muscle hypertrophy in response to resistance training.
Article Synopsis
- This study examined how resistance training affects both recruited and nonrecruited muscles over a 10-week period, focusing on muscle volume changes in novices targeting upper arms and legs.
- Findings revealed that while all recruited muscles showed significant growth, certain nonrecruited muscles like the adductor magnus and soleus actually decreased in volume.
- The results suggest that the hypertrophy of recruited muscles may come at the cost of atrophy in nonrecruited muscles, particularly in individuals with lower energy and protein intake.
Considerable inter-individual heterogeneity exists in the muscular adaptations to resistance training. It has been proposed that fast-twitch fibres are more sensitive to hypertrophic stimuli and thus that variation in muscle fibre type composition is a contributing factor to the magnitude of training response. This study investigated if the inter-individual variability in resistance training adaptations is determined by muscle typology and if the most appropriate weekly training frequency depends on muscle typology.
