Abstract
Objective: To determine the effects of submaximal interval training on anthropometric measurements, endurance, and flexibility of lower back and hamstrings in people with sedentary lifestyle.
Methods: A quasi-experimental design was employed in this study involving 20 sedentary participants (12 females and eight males mean age: 27.20±8.48. The study conducted at Physical Therapy gym Khyber Medical University Peshawar from January 2019 to June 2019. Over four weeks, participants underwent a submaximal interval training program, comprising treadmill walking or running at 70-80% of their maximum heart rate for one minute, followed by one minute of active recovery conducted three time weekly. Assessments comprised of endurance VO2 max using the Bruce Protocol, flexibility of the lower back extensors and hamstring muscles through the Young Man Christian Association (YMCA) sit and reach test, body mass index (BMI) and waist-hip ratio (WHR).
Results: The submaximal interval training intervention yielded significant improvements in endurance VO2 max, (p=0.001), flexibility (p=0.001) and BMI (p=0.016). However, the waist-hip ratio did not show any significant changes, mean pre-score (0.83±0.95) remaining the same in the post-score (0.83±0.93) (p=0.64).
Conclusion: The submaximal interval training intervention demonstrated a high level of tolerance, as evidenced by a remarkable adherence rate of 91% among participants. Moreover, this training approach exhibited significant enhancements in various physical parameters.
目的：确定亚极限间歇训练对久坐生活方式人群的人体测量、耐力、下背部和腘绳肌柔韧性的影响。方法：采用准实验设计，20名久坐不动的受试者（女性12人，男性8人）平均年龄：27.20±8.48岁。该研究于2019年1月至2019年6月在白沙瓦开伯尔医科大学物理治疗馆进行。在四周的时间里，参与者进行了次最大间歇训练计划，包括跑步机步行或以最大心率70-80%的速度跑步一分钟，然后每周进行三次一分钟的积极恢复。评估包括使用布鲁斯方案的耐力最大摄氧量，通过青年基督教协会（YMCA）坐姿和伸展测试的下背部伸肌和腘绳肌的灵活性，身体质量指数（BMI）和腰臀比（WHR）。结果：亚最大间歇训练干预对耐力VO2 max （p=0.001）、柔韧性（p=0.001）和BMI （p=0.016）均有显著改善。而腰臀比无明显变化，评分前均值（0.83±0.95）与评分后均值（0.83±0.93）持平（p=0.64）。结论：亚最大间歇训练干预表现出高水平的耐受性，参与者的依从率达到了91%。此外，这种训练方法在各种物理参数方面表现出显著的增强。
期刊介绍：
It is a peer reviewed medical journal published regularly since 1984. It was previously known as quarterly "SPECIALIST" till December 31st 1999. It publishes original research articles, review articles, current practices, short communications & case reports. It attracts manuscripts not only from within Pakistan but also from over fifty countries from abroad.
Copies of PJMS are sent to all the import medical libraries all over Pakistan and overseas particularly in South East Asia and Asia Pacific besides WHO EMRO Region countries. Eminent members of the medical profession at home and abroad regularly contribute their write-ups, manuscripts in our publications. We pursue an independent editorial policy, which allows an opportunity to the healthcare professionals to express their views without any fear or favour. That is why many opinion makers among the medical and pharmaceutical profession use this publication to communicate their viewpoint.
