Quotes From Source

None of the change in strength could be explained by muscle size.

Story of claim

Mediation analysis reveals that muscle size does not mediate strength gains, suggesting alternative mechanisms behind strength improvement.

  • Goal: Determine the relationship between muscle size and strength gain.
  • Proof: Mediation analysis showed that changes in strength are not driven by changes in muscle size.
  • Nuances:
    • Different exercise patterns applied to achieve growth differentiation.
    • Statistical approaches assess strength gain relative to control.
  • Impact on Life: Provides a basis for reevaluating training strategies focused on muscle size.

Investments

  • Price: Not mentioned
  • Time: Time required for analysis and statistical modeling.
  • Effort: Requires advanced knowledge of statistical methods.

Risks

None mentioned.

Get Started 🚀
