Effect of Moderate Intensity Continuous Training and Slow Type Interval Training to Gene Expression of TGF-β in Type...

Area of Science:

• Exercise physiology and molecular biology.
• Endocrinology and metabolic disease research.

Background:

• Physical exercise is crucial for managing type 2 diabetes mellitus (T2DM).
• T2DM impacts the expression of the Transforming Growth Factor-beta (TGF-β) gene.
• Understanding exercise's effect on TGF-β in T2DM is vital for therapeutic strategies.

Purpose of the Study:

• To investigate the impact of moderate-intensity continuous training (MICT) and slow interval training (SIT) on TGF-β gene expression in a T2DM rat model.
• To compare the efficacy of MICT versus SIT in modulating TGF-β gene expression in T2DM.

Main Methods:

• Wistar rats with T2DM were subjected to treadmill-based MICT (20 m/min, 30 min) or SIT (20 m/min, 2 min intervals with 1 min active rest, 10 repetitions).
• TGF-β gene expression was quantified using real-time polymerase chain reaction (PCR).

Main Results:

• MICT led to a statistically significant decrease in TGF-β gene expression (p < 0.05).
• SIT resulted in an insignificant decrease in TGF-β gene expression (p > 0.05).
• MICT demonstrated a trend towards being more effective than SIT in reducing TGF-β gene expression.

Conclusions:

• Both MICT and SIT influence TGF-β gene expression in T2DM rats.
• MICT appears to be a more effective exercise modality for significantly reducing TGF-β gene expression in this T2DM model.
• Findings suggest exercise type influences molecular pathways relevant to T2DM management.
