Comparison of acute hematologic responses of blood flow restriction training and resistance training in male fitness atheletes
(2022-12-01) Gülten S.; Gürses V.V.
BACKGROUND: High-intensity resistance training (HIRT) is recommended by The American College of Sports Medicine to improve muscle strength and hypertrophy. However, HIRT is not suitable for a significant portion of the population. If low-intensity resistance training (LIRT) is combined with blood flow restriction (BFR), it can improve muscle strength and hypertrophy and give similar results with HIRT. The aim of this study is to investigate the effects of HIRT and BFR+LIRT training methods on hematological parameters after training and 24 hours after training. METHODS: Thirteen men who have been active fitness atheletes for at least 1 year voluntarily participated in the research. Participants applied adaptation training, HIRT and LIRT+BFR, respectively, on 3 separate days. LIRT+BFR trainings were applied with 30-15-15-15 repetitions at an intensity of 30% of 1 maximum repetition (1 RM), and HIRT at an intensity of 70-72.5-75% of 1 RM with 3 sets * 10 repetitions with one-minute intervals. A metronome was used to control muscle actions in 2 seconds concentric and 2 seconds eccentric. Venous blood was taken at the 0th minute before the training, immediately after the training and 24 hours after the training. RESULTS: When the two training methods are compared; no statistical difference was found in WBC, NEUT, LYMPH, MONO, IG, %NEUT, %LYMPH, %MONO, %IG, RBC, HGB, %HCT, PLT, MCV, %MacroR, %MicroR, MPV and PLCR parameters (P<0.05). CONCLUSIONS: In conclusion, LIRT+BFR seems to be a good alternative to HIRT, which gives similar results with HIRT, but puts less load on the joints and causes less pain and trauma due to exercise.
The effects of low altitude training on erythropoietin response and hematological variables in elite female fencers
(2018-10-01) Gürses V.V.; Akgül M.Ş.
The Live High-Train High (LHTH) model altitude training is required to sojourn over 2000m more than 3 weeks. In such altitudes response that may cause decreased living, sleeping and training quality. In these cases coaches may approach with suspicion to LHTH can be harmful for their training intensity edgewise training quality. The aim of this study was to investigate the effect of 12 days 1850m training on some hematological parameters in the world-class woman fencers. Ten female fencers (age 21.50 ± 3.69, height 167.16 ± 3.88 cm, weight 59.11 ± 3.437 kg) voluntarily participated in this study. The athletes were investigated low altitude training camp at 1850m. The blood samples were taken before and after the moderate altitude training for analyzing erythropoietin (EPO), red blood cell (RBC), hemoglobin (HB) and hematocrit (HCT) concentration levels. The paired sample t-test was used for determine the differences pre and posttests results, significance levels p<0.05 Results shows that concentrations of EPO increased significantly after twelve days low altitude training. However RBC, HB, HCT concentrations were unaffected by the hypoxic stimulus. The results of this study have suggested that the 12 days LHTH training at 1850 m can be stimulated EPO. This means 1850 m altitude possibly induces hypoxic effect. Nevertheless, 12 days altitude training is not enough to enhance performance related blood markers.
