Participants in the LRS and RT-LRS groups consumed 500 mg of<br />LRS daily for 8 weeks. RT was conducted 3 times/week for 8 weeks for participants in the RT<br />and RT-LRS groups. The following parameters were measured before and after the intervention<br />period: Anthropometric data, isokinetic muscular strength and power, and anaerobic and aerobic<br />fitness. Blood samples were also collected to determine immune parameters.</p><p><strong>Results:</strong> Isokinetic muscular strength and power were increased (P &lt; 0.05) in participants of both<br />RT and RT-LRS groups. RT-LRS group had shown increases (P &lt; 0.05) in shoulder extension<br />peak torque, shoulder flexion and extension average power, knee flexion peak torque, and knee<br />flexion and extension average power. There were also increases (P &lt; 0.05) in anaerobic power and<br />capacity and aerobic fitness in this group. Similarly, RT group had increases (P &lt; 0.05) in shoulder<br />flexion average power, knee flexion and extension peak torque, and knee flexion and extension<br />average power. In addition, increases (P &lt; 0.05) in anaerobic power and capacity, aerobic fitness,<br />T lymphocytes (CD3 and CD4), and B lymphocytes (CD19) counts were observed in the RT group.</p><p><strong>Conclusions:</strong> RT elicited increased isokinetic muscular strength and power, anaerobic and<br />aerobic fitness, and immune parameters among young males. However, supplementation with<br />LRS during RT did not provide additive benefits.</p><p><strong>Keywords:</strong> Aerobic fitness, immune parameters, Lignosus rhinocerotis, muscular fitness, resistance training</p>http://ijpm.mui.ac.ir/index.php/ijpm/article/view/1732http://ijpm.mui.ac.ir/index.php/ijpm/article/download/1732/2022
