تأثیر 10 هفته ترکیب تمرین مقاومتی ایزومتریک و ایزوتونیک در آب بر میزان شاخص‌های خستگی مردان سالمند

Abstract Introduction and purpose : Fatigue is one of the most common signs of aging that is often overlooked or linked to other conditions, but if left untreated, fatigue in the elderly can lead to loss of normal function. Materials and Methods: Fourty elderly men with an average age of 69.71 ± 1.92 years were volunteered to participate in the control and practice groups. The experimental group participated in water exercise program for 10 weeks, three sessions per hour a week. In both groups, weight, body mass index, walking time to exhaustion and blood lactate levels were measured after extinction, before and after the measure was intended. The exercise protocol included a combination of isometric and isotonic exercises in water. The covariance test was used at a significant level of 0.05. Results: The results of paired t-test showed that 10 weeks of isometric and isotonic resistance training combination in water affects the level of elderly fatigue indexes. And resistance training had a significant effect on walking time improvement (p = 0.039) and blood lactate (p = 0.005) after walking to endurance level in the training group but this difference was not observed in the control group (P>0/05). Conclusion: According to the results of this study, the use of isometric and isotonic resistance training in water can have a positive effect on fatigue indexes, especially on improving walking time and decreasing lactate levels in elderly people after walking to exhaustion, and it is suggested that due to good water benefits for Elderly, water resistance exercises will be on the agenda in trainers, experts and activists in the field.
