Abstract
Although exercise and dietary supplementations were postulated to be beneficial for health and physical fitness, the issue of combined effects of resistance training and Tiger Milk Mushroom supplementation is still lacking in the literature and not well documented. This study was carried outto investigate the beneficial combined effects of 8 weeks of (Tiger Milk Mushroom) supplementation and resistance training on isokinetic muscular strength and power, anaerobic and aerobic fitness, and immune functions among young males. In this double blind placebo-controlled trial, 38 young males (19-25 years old) were assigned into four groups with 9 t0 10 participants per group: Control (C) group, Tiger Milk Mushroom (TMM) group, resistance training (RT) group and combined resistance training and Tiger Milk Mushroom (RT&TMM) group. Participants in TMM group and RT&TMM group consumed two capsules of TMM (250mg per capsule) 7 days per week for 8 weeks. Participants in the control (C) group and RT group participants were consumed placebo capsules for 7 days per week for 8 weeks. Resistance training programme consisted of 10 different types of exercise which involved muscle of the upper and lower limbs. It was conducted three times per week for 8 weeks. Lignosus Rhinocerus Prior to the intervention period, pre-test was carried out to measure anthropometric measurements, isokinetic muscular strength and power, anaerobic and aerobic fitness. Blood samples were also withdrawn in order to determine immune function parameters through full blood counts and immunophenotyping. After 8 weeks of intervention period, all these parameters were measured again during post test. Positive effects observed in isokinetic muscular strength and power in combined RT&TMM group were peak torque of shoulder extension at 60o.s-1, average power of shoulder flexion and extension at 300o.s-1, peak torque of knee flexion at 60o.s-1, average power of knee flexion and extension at 300o.s-1. In addition, there were also increases in anaerobic power and capacity and estimated maximum oxygen consumption. Similarly, positive effects in RT alone group, were observed in the isokinetic muscular strength and power parameters such as average power of shoulder flexion at 300o.s-1,peak torque of knee flexion and extension at 60o.s-1, average power of knee flexion and extension at 300o.s-1. Additionally, increases in anaerobic power and capacity, aerobic fitness, T lymphocytes (CD3 and CD4) and B lymphocytes (CD19) counts were observed in RT alone group. Resistance training with dumbbells and elastic bands elicited increased isokinetic muscular strength and power, anaerobic and aerobic fitness and immune functions among young males. However, combining resistance training with Tiger Milk Mushroom did not result in additional benefits.
