Low-load blood flow restriction (BFR) training offers similar benefits to HLRT while reducing these issues. This study aimed to compare the effects of traditional HL-RT and low-load BFR training on muscular strength, power, endurance, and running performance of collegiate 800-m runners over an 8-week training program.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A total of 22 participants were randomly divided into HL-RT group (n = 11) and BFR group (n = 11). Physical performance was assessed at three time points: baseline, mid-intervention, and post-intervention. The tests included the 20-m sprint test (T20m), countermovement jump test (CMJ), smith machine full-squat test (to assess V1 load), plantar flexion rate of force development test (PF-RFD), 200-m test (T200m), and 800-m test (T800m).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Significant time effects were observed for T20m, CMJ, V1 load, PF-RFD, T200m, and T800m (all P &amp;lt; 0.05), and significant interaction effects between time and group was found for V1load (P &amp;lt; 0.05). Post-training comparisons between the HL-RT and BFR groups revealed a significant improvement in V1 load in the HL-RT group (P &amp;lt; 0.05), while no significant differences were found between the groups for the other performance measures. The present results indicate that both HL-RT and BFR training demonstrate positive effects on the muscular strength, power, endurance, and running performance, while HL-RT demonstrate greater gains in muscular power.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Low-load BFR training offers an effective alternative to traditional HL-RT for enhancing competitive performance and key physical attributes in collegiate 800-m runners.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fphys.2025.1678604","type":"journal-article","created":{"date-parts":[[2025,9,30]],"date-time":"2025-09-30T05:28:00Z","timestamp":1759210080000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Comparative effects of low-load blood flow restriction training and high-load resistance training on physical performance in college 800-m runners: a randomized control trial"],"prefix":"10.3389","volume":"16","author":[{"given":"Jianhua","family":"Yu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jingyan","family":"Yu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lei","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi","family":"Yang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2025,9,30]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1318","DOI":"10.1152\/japplphysiol.00283.2002","article-title":"Increased rate of force development and neural drive of human skeletal muscle following resistance training","volume":"93","author":"Aagaard","year":"1985","journal-title":"J.
