Effect of voluntary wheel running on gut microbiota composition in developing mice

Area of Science:

• Microbiology
• Developmental Biology
• Exercise Science

Background:

• Exercise influences gut microbiota, promoting beneficial bacteria and diversity.
• Limited research exists on short-term exercise effects on the gut microbiome in developing animals.

Purpose of the Study:

• To investigate the impact of short-term voluntary wheel running on the gut microbiota of 1-month-old mice.
• To analyze changes in gut microbial composition and diversity following exercise intervention.

Main Methods:

• Utilized a voluntary wheel running model in developing mice.
• Analyzed fecal samples using 16S rRNA gene sequencing to assess gut microbiota.

Main Results:

• Voluntary wheel running for 4 weeks led to a significant decrease in body weight compared to controls.
• Significant differences in beta diversity were observed between running and control groups.
• Specific bacterial families like Clostridiales, Parabacteroides, and Anaerovorax showed altered abundance, while Anaerotruncus and Odoribacter decreased.

Conclusions:

• Short-term voluntary wheel running significantly impacts the gut microbiota composition in developing mice.
• Exercise intervention alters microbial diversity and the abundance of key bacterial taxa.
• Findings suggest exercise plays a role in shaping the gut microbiome during early development.
