Sub-optimal muscular performance is related to physical strength and performance that affects movement and metabolism. (source)
Suboptimal muscle performance can detrimentally impact physical performance across various domains. It can impair movement efficiency, leading to reduced speed, agility, and coordination. Additionally, sub-optimal muscle function can affect metabolic processes, potentially impacting energy production. Supporting optimal muscle function ensures efficient force production, leading to optimal physical performance.
Supplement with Creatine: Creatine supplementation has been shown to improve strength performance. (source) Creatine serves as a quick energy reserve which increases work capacity and facilitates muscle strength and hypertrophy. (source) Recommendation: Supplement with at least 3 g of creatine daily.
Supplement with Vitamin D: Vitamin D supplementation has been shown to influence muscle quality and fiber expression, which are positively associated with muscle performance. (source, source, source) Recommendation: Supplement with up to 2,000 IU of vitamin D daily.
