This study aimed to investigate the effectiveness of a supervised physical training program with controlled cadence on functional fitness parameters, quality of life perception, and physical activity level in older adults.
Sixty physically independent older adults were randomly divided into three groups: Supervised Training (ST, = 20), Unsupervised Training (UT, = 20), and a Control Group (C, = 20). The ST and UT groups participated in a 12-week program, performing exercises three times a week for 30 min. The ST group had structured weekly sessions consisting of a 5-minute warm-up (walking at 60% of max heart rate), 20 sets of 30 s at a moderate pace controlled by a metronome with 30 s of passive recovery, and a 5-minute cool-down on non-consecutive days. The UT group trained spontaneously using senior gym equipment, including elliptical machines, rowing machines, air skiers, and leg press machines. The control group maintained their usual daily routines throughout the study. Parameters evaluated included body mass, body mass index (BMI), muscle thickness (biceps brachii, triceps brachii, and vastus lateralis), and functional capacity tests (walking 10 m [W10 m], rising from a sitting position [RSP], rising from the prone position [RVDP], sitting and rising from a chair and moving around the house [SRCW]). Quality of life was assessed across physical, psychological, environmental, and social domains, and physical activity levels were also measured.
No significant changes ( > 0.05) in body mass, BMI, or muscle thickness were observed between groups before and after the intervention. However, significant time effects in functional fitness tests were found only in the ST group for W10 m ( = 0.0469), RVDP ( < 0.0004), RSP ( < 0.0001), and SRCW ( < 0.0001). Quality of life improved significantly over time in the ST and UT groups across all domains ( < 0.0001). Both ST and UT groups also showed significant increases in weekly physical activity time ( > 0.0001).
12 weeks of training improved quality of life perception and physical activity levels in older adults.
本研究旨在调查一项有监督的、节奏受控的体育训练计划对老年人身体功能参数、生活质量感知和身体活动水平的有效性。
60名身体独立的老年人被随机分为三组:监督训练组(ST,n = 20)、无监督训练组(UT,n = 20)和对照组(C,n = 20)。ST组和UT组参加为期12周的计划,每周进行三次运动,每次30分钟。ST组每周有结构化的课程,包括5分钟的热身(以最大心率的60%步行),在节拍器控制的中等节奏下进行20组,每组30秒,每组间有30秒的被动恢复时间,以及在非连续的日子进行5分钟的冷却。UT组使用包括椭圆机、划船机、空中滑雪机和腿部推举机在内的老年健身器材自发进行训练。对照组在整个研究过程中保持其日常习惯。评估的参数包括体重、体重指数(BMI)、肌肉厚度(肱二头肌、肱三头肌和股外侧肌)以及功能能力测试(步行10米[W10m]、从坐姿起身[RSP]、从俯卧位起身[RVDP]、从椅子上坐起并在屋内走动[SRCW])。在身体、心理、环境和社会领域评估生活质量,并测量身体活动水平。
干预前后,各组之间的体重、BMI或肌肉厚度均未观察到显著变化(p > 0.05)。然而,仅在ST组的功能适应性测试中发现了显著的时间效应,对于W10m(p = 0.0469)、RVDP(p < 0.0004)、RSP(p < 0.0001)和SRCW(p < 0.0001)。随着时间的推移,ST组和UT组在所有领域的生活质量均有显著改善(p < 0.0001)。ST组和UT组的每周身体活动时间也均有显著增加(p > 0.0001)。
12周的训练改善了老年人的生活质量感知和身体活动水平。
