The purpose of this study was to examine the effects of elastic band exercises and nutritional education, as well as to identify the factors influencing frailty, strength, and nutritional intake of elderly women.
The subjects in this study were 30 elderly women who were divided into four groups. All groups agreed to participate in four programs: health education only (HE), elastic band exercises only (EX), nutritional education only (NU), and elastic band exercises plus nutritional education (EX+NU). Frailty was evaluated by measuring the frailty factors according to Fried et al. Leg strength was measured using a leg-extension machine. Nutritional intake was assessed by the 24-hour recall method and food records. Nutritional intake was analyzed by CAN Pro 5.0 program.
After three months, the prevalence of frailty significantly decreased in the EX+NU group (P=0.013) compared with that of the HE group (P=0.088). There was significant improvement in leg strength in both the EX (P=0.012) and EX+NU groups (P=0.003) compared with that of the HE group (EX, P=0.005; EX+NU, P=0.002). The nutritional intake significantly decreased in the EX group compared with that of the HE group (P<0.05, P<0.05).
The combination of elastic exercises and nutrition education had positive effects on frailty and leg strength, while having negative effects on total calories, carbohydrate, sodium, and iron intake in elderly women. Elastic exercises only had positive effects on leg strength while having negative effects on nutritional intake in elderly women.
本研究旨在探讨弹力带运动和营养教育的效果,并确定影响老年女性虚弱、力量和营养摄入的因素。
本研究的受试者为30名老年女性,她们被分为四组。所有组均同意参加四个项目:仅健康教育(HE)、仅弹力带运动(EX)、仅营养教育(NU)以及弹力带运动加营养教育(EX+NU)。根据Fried等人的方法,通过测量虚弱因素来评估虚弱状况。使用腿部伸展机测量腿部力量。通过24小时回忆法和食物记录评估营养摄入情况。使用CAN Pro 5.0程序分析营养摄入。
三个月后,与HE组(P=0.088)相比,EX+NU组的虚弱患病率显著降低(P=0.013)。与HE组相比,EX组(P=0.012)和EX+NU组(P=0.003)的腿部力量均有显著改善(EX组,P=0.005;EX+NU组,P=0.002)。与HE组相比,EX组的营养摄入量显著降低(P<0.05,P<0.05)。
弹力运动与营养教育相结合对老年女性的虚弱和腿部力量有积极影响,而对总热量、碳水化合物、钠和铁的摄入量有负面影响。仅弹力运动对老年女性的腿部力量有积极影响,而对营养摄入有负面影响。
