Abstract

Introduction: Resistance exercises are the important part of an exercise program in most sports, which has a role in preventing injury and rehabilitation. The aim of the present research was to compare 9 weeks of linear, and wave scheduled and unscheduled resistance exercise on strength and endurance as well as neuromuscular performance of the upper and lower torso muscles in men. Methods: Thirty men with the mean age of (21.87 ± 3.06 years), height (173.55 ± 6.14) and weight (73.35 ± 13.56) were randomly divided into three groups of unscheduled (n =10), linear (n =10) and wave (n =10) scheduled exercise. The exercise protocol was for 9 weeks exercise and three sessions per week. At the end, the strength and endurance of the muscles were measured. The electromyography activity of the quadriceps muscle was recorded by an electromyographic device. The two-way ANOVA statistical test was used for data analysis. Findings: Data analysis showed that the strength and endurance of the upper and lower torso muscles and the amplitude of the electromyographic wave had a significant increase in all three groups compared to before doing the exercises (P <0.05). Intergroup results showed that wave exercises had a significant effect on strength and endurance and the amplitude of electromyographic wave compared to linear and unscheduled exercises (P <0.05). Discussion: The results of this research showed that by using a wave exercise program concurrent with paying attention to saving time and energy compared to other exercise programs, significant results in gaining muscular strength and endurance, as well as further call for motor units and neuro-muscular adaptation can be achieved.
