Deep dives
Micronutrients and Strength Gains
The study reveals that muscle strength gains in older women depend more heavily on micronutrient intake than on protein alone. While both high-speed resistance and multi-component training improved strength, deficiencies in micronutrients like vitamin D and B12 were significant factors in limiting strength gains. Iron, magnesium, potassium, and vitamin E also played roles specific to individuals in high-speed training. This indicates that women over 30, especially those at risk of sarcopenia, need to ensure they are not only consuming enough protein but are also meeting their micronutrient requirements to effectively enhance their strength.
