The aim of this study was to investigate changes in heart rate during submaximal exercise as an index of cardiovascular function in older adults participating in the Groningen Active Living Model recreational sports programme who were sedentary or underactive at baseline. A repeated measurement design was conducted; 151 participants were included, providing 398 heart rate files over a period of 18 months. Multi-level analyses were conducted; growth and final models were developed. Significant decreases in mean heart rate over time were observed for all walking speeds. The covariates of sex and body mass index (BMI) were significantly related to mean heart rate at each walking speed, except for BMI at 7 km/h. No significant relationships were observed between energy expenditure for recreational sports activities and leisure-time physical activities and mean heart rate, except for energy expenditure for leisure-time physical activities at 7 km/h. From baseline to December 2002, decreases in predicted mean heart rate were 5.5, 6.0, 10.0, and 9.0 beats/min at walking speeds of 4, 5, 6, and 7 km/h; relative decreases ranged from 5.1 to 7.4%. Significant decreases in heart rate observed during submaximal exercise reflected a potential increase in cardiovascular function after 18 months of participation in the Groningen Active Living Model recreational sports programme.DOI:10.1080/02640410903008749

Physical inactivity has led to an increase in the prevalence of lifestyle-related chronic diseases on a global scale. There is a need for more awareness surrounding the preventive and curative role of a physically active lifestyle in healthcare. The prescription of physical activity in clinical care has been advocated worldwide through the ‘exercise is medicine’ (E=M) paradigm. However, E=M currently has no position in general routine hospital care, which is hypothesized to be due to attitudinal and practical barriers to implementation. This study aims to create an E=M tool to reduce practical barriers to enforcing E=M in hospital care. Firstly, this project will perform qualitative research to study the current implementation status of E=M in clinical care as well as its facilitators and barriers to implementation among clinicians and hospital managers. Secondly, an E=M tool towards application of active lifestyle interventions will be developed, based on a prediction model of individual determinants of physical activity behavior and local big data, which will result in a tailored advice for patients on motivation and physical activity. Thirdly, the feasibility of implementing the E=M-tool, as designed within this project, will be investigated with a process evaluation, conducting a pilot-study which will integrate the tool in routine care in at least four clinical departments in two Dutch hospitals. This project will give insight in the current implementation status of E=M and in factors that influence the actual E=M implementation. Secondly, an E=M tool will be designed providing a tailored E=M prescription for patients as part of clinical care. Thirdly, an implementation strategy will be developed for implementation of the E=M tool in clinical practice. This project envisages an extensive continuation of research on the implementation of E=M, supports the mutual decision making process of lifestyle referral of clinicians and will provide insights which can be used to assist in implementing physically active lifestyle prescription in the medical curriculum.

Athletes who wish to resume high-level activities after an injury to the anterior cruciate ligament (ACL) are often advised to undergo surgical reconstruction. Nevertheless, ACL reconstruction (ACLR) does not equate to normal function of the knee or reduced risk of subsequent injuries. In fact, recent evidence has shown that only around half of post-ACLR patients can expect to return to competitive level of sports. A rising concern is the high rate of second ACL injuries, particularly in young athletes, with up to 20% of those returning to sport in the first year from surgery experiencing a second ACL rupture. Aside from the increased risk of second injury, patients after ACLR have an increased risk of developing early onset of osteoarthritis. Given the recent findings, it is imperative that rehabilitation after ACLR is scrutinized so the second injury preventative strategies can be optimized. Unfortunately, current ACLR rehabilitation programs may not be optimally effective in addressing deficits related to the initial injury and the subsequent surgical intervention. Motor learning to (re-)acquire motor skills and neuroplastic capacities are not sufficiently incorporated during traditional rehabilitation, attesting to the high re-injury rates. The purpose of this article is to present novel clinically integrated motor learning principles to support neuroplasticity that can improve patient functional performance and reduce the risk of second ACL injury. The following key concepts to enhance rehabilitation and prepare the patient for re-integration to sports after an ACL injury that is as safe as possible are presented: (1) external focus of attention, (2) implicit learning, (3) differential learning, (4) self-controlled learning and contextual interference. The novel motor learning principles presented in this manuscript may optimize future rehabilitation programs to reduce second ACL injury risk and early development of osteoarthritis by targeting changes in neural networks.
