Both groups completed an 8-week elastic resistance training program. The measured outcomes included extended body composition (BMD, T-scores, lean mass, and fat mass) and functional fitness components (cardiorespiratory endurance, muscular strength, endurance, and flexibility).\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n No significant changes in BMD were observed in either group (\n p<\/jats:italic>\n \u202f&gt;\u202f0.05). The HIRT group demonstrated significant improvements in lean mass (\n p<\/jats:italic>\n \u202f&lt;\u202f0.001), chest press strength (\n p<\/jats:italic>\n \u202f=\u202f0.024), muscular endurance (\n p<\/jats:italic>\n \u202f=\u202f0.008), and VO\u2082peak (\n p<\/jats:italic>\n \u202f=\u202f0.001), while the MIRT group showed no significant changes. Flexibility and fat mass did not significantly differ in either group (\n p<\/jats:italic>\n \u202f&gt;\u202f0.05).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n High-intensity resistance training was more effective than MIRT in improving lean mass and functional fitness in individuals with motor-complete SCI. Although BMD did not change over the 8-week period, its assessment remains clinically relevant, and future studies should investigate longer-duration or higher-intensity protocols to promote skeletal adaptations.<\/jats:p>\n
