This study investigates the relationship between nutrient intake and response to training in older women at risk of sarcopenia. Methods: A randomized clinical trial with two parallel groups (high-speed resistance training (H-RT) and multicomponent training (MT)) was conducted over a 32-week intervention involving 80 older women at risk of sarcopenia (mean age: 77.36 ± 6.71 years). A food frequency questionnaire was administered to assess whether nutrient intake influenced strength outcomes measured by the Five Times Sit-to-Stand Test (5STS) and other functional variables. Results: Significant improvements in the five times sit to stand test (5STS) were observed in both groups post-intervention (p < 0.001), with no significant differences between them (p = 0.127), suggesting comparable effectiveness. In both groups, lower levels of vitamin B12 (H-RT: rp = −0.52; MT: rp = −0.50) and vitamin D (H-RT: rp = −0.55; MT: rp = −0.69) were associated with worse 5STS performance. Additionally, in the H-RT group, lower levels of vitamin E (rp = −0.36), magnesium (rp = −0.48), iron (rp = −0.43), and potassium (rp = −0.47) were also correlated with poorer performance. Conclusions: The results indicate that improvements in strength are related to micronutrient sufficiency rather than macronutrient sufficiency. Deficiencies in vitamin D and B12 negatively impacted muscle strength gains in both H-RT and MT, while vitamin E, potassium, magnesium, and iron influenced H-RT outcomes. The lesser effect of micronutrient deficiencies on MT suggests it may be more suitable for individuals with mild deficiencies, as it requires fewer specific nutrients for muscle strength.
