Background
As older-aged population is continuously increasing, it is essential to promote physical activity (PA) to preserve health and autonomy in daily living. Although several methods have been proposed, combining sustainability and efficacy at the same time is still a challenge.
Aims
To evaluate the effects of a semi-structured PA (SSPA) intervention including aerobic as well as strength and flexibility exercise in comparison to generic PA advice (PAAdv) in healthy older adults.
Methods
86 sedentary older adults were divided in two groups, SSPA (n = 56) and PAAdv (n = 30). Body weight (BW) and circumferences, blood pressure (BP), submaximal exercise heart rate (HR), as well as Chair Stand Test (CST), Arm Curl Test (ACT), Chair Sit-and-Reach Test (CSRT) and Back Scratch Test (BST) were performed before and after 16 weeks of intervention. SSPA group was further divided in SSPA > 500 and SSPA < 500 according to the total amount of PA performed (cut-off level of 500 MET min/week).
Results
Overall, SSPA groups improved more than the PAAdv group on WC, HC, BP, CST, ACT, CSRT and BST. SSPA > 500 improved more than SSPA < 500 and PAAdv on CST (+ 20.2, + 11.3, + 4.5% respectively), ACT (+ 21.5, + 14.9, − 1.3%, respectively), and CSRT (+ 3.7, + 0.80, + 0.75 cm, respectively), and similarly to SSPA < 500 on BST. Submaximal HR values significantly decreased for the SSPA > 500 and PAAdv groups.
Conclusions
An SSPA program represents an ecological way to enhance fitness in older adults. A greater amount of SSPA (> 500 versus < 500 MET min/week) is associated with higher cardiovascular and muscular fitness benefits.
