The Effects of Stretching Training on Erythrocyte Rheological Properties and Anaerobic Performance in Healthy Young Males

23562

Purpose: Stretching exercise training is used to improve flexibility and performance. This study aimed to investigate the short and long-term effects of stretching exercise on flexibility, performance, red blood cell (RBC) deformability and aggregation.Materials and methods: 7 young male subjects (mean age 20.71±0.52 years) participated in the study.Stretching protocol consisted of 3 repetitions for 60 seconds, 3 days/week, applied for 6 weeks. Blood samples were obtained before and immediately after the first stretching exercise and on the last day of the program.Flexibility measurement was performed, as well as counter movement, squat jump, sprint tests. Hemorheological parameters were determined using an ektacytometer.Results: A significant elevation in flexibility and decrement in sprint time were observed. Following an acute insignificant elevation immediately after the exercise on the first day, RBC deformability was slightly decreased on the last day after the exercise. RBC aggregation significantly decreased immediately after the stretching exercise on the first day, while post-exercise elevation was detected on the 6th week.Conclusion: The results of the current study indicate that the stretching exercise training used to develop physical capacity of the athletes contributes to blood flow and thus, athletic performance of the individual by inducing acute increments in RBC deformability and through decrements in erythrocyte aggregation.
