Current Nutritional and Pharmacological Approaches for Attenuating Sarcopenia

Area of Science:

• Gerontology
• Muscle Physiology
• Nutritional Science

Background:

• Sarcopenia, characterized by muscle mass and strength decline, increases fall risk and weakness in aging populations.
• Nutritional and pharmacological interventions are crucial for managing sarcopenia, with limited human data necessitating reliance on mammalian studies.

Purpose of the Study:

• To review recent research on nutritional and pharmacological strategies for controlling sarcopenia.
• To evaluate the efficacy of various supplements and treatments for age-related muscle loss.

Main Methods:

• Literature review focusing on nutritional and pharmacological approaches to sarcopenia.
• Inclusion of data from mammalian studies due to limitations in human nutritional research.

Main Results:

• Combining resistance training with amino acid supplements is the established approach for sarcopenia prevention.
• Beta-hydroxy beta-methylbutyrate (HMB) alone is ineffective, but combined with exercise (e.g., whole body vibration), it may be beneficial.
• Tea catechins, soy isoflavones, and ursolic acid require further research; Vitamin D is ineffective in non-deficient elderly; myostatin inhibitors show potential but warrant cautious optimism.

Conclusions:

• Resistance training plus amino acids remains the gold standard for sarcopenia prevention.
• Specific supplements and novel pharmacological agents show promise but require more human clinical validation.
• Current evidence suggests a multifaceted approach combining exercise and targeted nutritional or pharmacological interventions is necessary for effective sarcopenia management.
