Forty national-level young male athletes volunteered to participate in this study and were divided into sSIT, RT, sSIT + RT, RT + sSIT, and active control (CG) groups, each group consisted of eight athletes and performed 3 days of weekly training intervention including 4 sets of 5 repetitions of 5 seconds of all-out running for sSIT program and also back squats, leg presses, seated knee flexions, and calf raises for 3 sets of 6-12 repetition maximum for the RT intervention. After the intervention, the sSIT, RT, sSIT + RT and RT + sSIT groups demonstrated improvements in the countermovement vertical jump (CMVJ) (effect size [ES] = 0.64, 0.88, 1.58, 1.55), 20-m sprint (ES = -0.82, -0.62, -1.10, -1.16), 4 \u00d7 9-m shuttle run (ES = -0.62, -0.35, -1.15, -0.89), strength (ES = 0.19, 0.44, 0.34, 0.43), peak (ES = 1.27, 0.73, 1.80, 1.53), and mean power output (ES = 0.87, 0.54, 1.37, 1.11), as well as in comparison to the CG (p &lt; 0.05), respectively. Additionally, improvements in aerobic performance were observed in the sSIT, sSIT + RT, and RT + sSIT groups (ES = 0.75, 0.92, 0.62) after the training intervention, and in comparison to CG (p &lt; 0.05), while the RT group did not show significant changes post-training. By comparing the CT groups, no sequencing effects were observed in the adaptations of variables between the sSIT + RT vs. RT + sSIT groups. In conclusion, this study's findings demonstrate that sSIT, RT, and CT with different orders have a positive impact on inducing adaptations in physical fitness, aerobic and anaerobic performance. Additionally, combining sSIT and RT resulted in further adaptations in karate athletes without any differences between CT groups.<\/jats:p>","DOI":"10.52082\/jssm.2025.205","type":"journal-article","created":{"date-parts":[[2025,3,1]],"date-time":"2025-03-01T10:45:48Z","timestamp":1740825948000},"page":"205-216","source":"Crossref","is-referenced-by-count":8,"title":["Sequencing Effects of Concurrent Resistance and Short Sprint Interval Training on Physical Fitness, and Aerobic and Anaerobic Performance of Karate Athletes"],"prefix":"10.52082","author":[{"given":"Yifan","family":"Xu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shimeng","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"29163","published-online":{"date-parts":[[2025,3,1]]},"reference":[{"key":"ref0","doi-asserted-by":"publisher","unstructured":"Aagaard P., Andersen J.L., Bennekou M., Larsson B., Olesen J.L., Crameri R., Kjaer M.
