Investigating the Hemorheological, Metabolic, and Physical Performance Effect of a Core Muscle Strengthening Training...

Area of Science:

• Exercise physiology
• Hematology
• Sports science

Background:

• Physical activity impacts red blood cell (RBC) deformability and aggregation, influencing oxygen transport and athletic performance.
• Adaptations in RBC properties due to training are contingent upon exercise intensity, duration, and recovery protocols.

Purpose of the Study:

• To evaluate the effects of a 12-week core muscle training program on RBC deformability, aggregation, and aerobic capacity in military trainees.
• To investigate potential hemorheological adaptations in response to a structured core training intervention.

Main Methods:

• Thirty-five male military trainees were assigned to a Training group (n=17) or a Control group (n=18).
• The intervention involved dynamic stretching, core stabilization, and functional movement exercises over 12 weeks.
• Pre- and post-intervention assessments included spiroergometry, blood gas analysis, and hemorheological measurements.

Main Results:

• No significant changes in body composition or aerobic capacity were observed in either group.
• RBC deformability showed a slight decrease post-exercise, while RBC aggregation increased in both groups.
• The Training group exhibited more moderate changes in blood viscosity compared to the Control group, indicating potential adaptation.

Conclusions:

• The 12-week core training program did not significantly enhance RBC properties or aerobic capacity, likely due to insufficient training intensity.
• While some hemorheological benefits were suggested by moderate blood viscosity changes, optimal adaptation requires adequate intensity, recovery, and nutrition.
• Individualized training strategies are crucial for maximizing performance and hemorheological benefits through physical activity.
