Plain-language summary
A plain-language read of the study’s main message and where it applies.
Study focus
This study investigated the effects of astaxanthin supplementation and combined training on metabolic indices in women with type 2 diabetes, finding significant improvements in certain outcomes.
These findings highlight the importance of physical activity in managing type 2 diabetes, suggesting that combined training can effectively enhance metabolic health. For clinicians, this underscores the need to promote exercise as a key component of diabetes management, while the limited impact of astaxanthin supplementation alone suggests it should not replace traditional lifestyle interventions.
The study did not assess long-term effects beyond the intervention period. Sample size and demographic limitations may affect generalizability. The effects of astaxanthin supplementation were unclear and not statistically significant.

Humanin levels increased significantly in combined training groups (p < 0.05).
Fasting blood glucose improved significantly in combined training groups.
Insulin resistance (HOMA-IR) improved significantly in combined training groups.
