Effekterna av praktisk ocklusionsträning periodiserat med ett traditionellt styrketräningsprogram på anaerob prestation

Background: Practical blood flow restriction (pBFR) combined with resistance training has been proven to facilitate muscle strength despite training at low intensity. However, research investigating the effects of long-term pBFR-training and its periodization with strength training (ST) at a higher intensity is lacking, as well as the effects of occlusion training on blood lactate levels (BLL) over time. Purpose: To compare the effects of 2 weeks of pBFR training followed by 2 weeks of ST (BFR-ST) with 2 weeks of ST followed by 2 weeks of pBFR training (ST-BFR) on anaerobic performace and BLL. Method: 5 adults (age 23 ± 2 years) with a minimum of 1 year of ST experience were recruited and randomized into BFR-ST (n=2) or ST-BFR (n=3). Anaerobic performance was measured using a 30-s Wingate-test and BLL samples were collected <1 and 5 minutes post-Wingate. Data and samples were collected before the intervention and after the 2 protocols. Results: No differences were seen between groups in anaerobic output or BLL after 4 weeks of training (p>0,1 for all values). A decrease in time to peak power (tPP) were seen in both groups with an advantage for BFR-ST (-37 ± 8 %) over ST-BFR (-27 ± 22 %). BLL decreased after 2 weeks of pBFR (-14 ± 26 % at <1 min and -7 ± 14 % at 5 min) and increased after 2 weeks of ST (+26 ± 45 % at <1 min and +8 ± 20 % at 5 min). Conclusion: The results of this study suggests that occlusion training in conjunction with resistance training can reduce tPP, that BFR-ST has greater impact on this quality compared to ST-BFR and that pBFR-training seems to lower post-Wingate BLL. Thus pBFR-training combined with ST could be an interesting alternative to a traditional periodized resistance training program.
