This study reviews the preferences for physical activity in adults aged 65 years and older. The term “preferences for

Comprehensive evaluation of prior interventions designed to increase preschoolers’ physical activity is lacking. This systematic review aimed to examine the effect of interventions on objectively measured physical activity in children aged 2–5 years. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. In May 2014, we searched PubMed, CINAHL, PsycINFO, ERIC, SPORTDiscus, Cochrane, and Embase. Two reviewers independently identified and appraised the studies. Twenty-four articles describing 23 independent studies and 20 unique interventions met inclusion criteria. Of the 8 interventions resulting in a significant effect in objectively measured physical activity, all were center-based and included a structured physical activity component, 6 included multiple components, 5 integrated theories or models, and 4 actively involved parents. Seven of the 8 were randomized controlled trials. Due to the heterogeneity of the study designs, physical activity measures, and interventions, drawing definitive conclusions was difficult. Although the overall intervention effect was less than optimal, the review indicated that theory-driven, multicomponent interventions including a structured physical activity component and targeting both parents and their children may be a promising approach for increasing preschoolers’ physical activity and warrant continued investigation using rigorous designs to identify those that are most effective.

These theoretical investigations can take three possible forms ( Ato, López-García, & Benavente, 2013 ): (a) Narrative reviews – a

Background/objectives:

Sedentary behavior (SB), defined as sitting (nonexercising), reclining, and lying down (posture), or by low energy expenditure, is a public health risk independent to physical activity. The objective of this systematic literature review was to synthesize the available evidence on amount of SB reported by and measured in older adults.

Data source:

Studies published between 1981 and 2014 were identified from electronic databases and manual searching. Large-scale population studies/surveys reporting the amount of SB (objective/subjective) in older adults aged ≥ 60 years of age were included. Appraisal and synthesis was completed using MOOSE guidelines.

Results:

349,698 adults aged ≥ 60 within 22 studies (10 countries and 1 EU-wide) were included. Objective measurement of SB shows that older adults spend an average of 9.4 hr a day sedentary, equating to 65–80% of their waking day. Self-report of SB is lower, with average weighted self-reports being 5.3 hr daily. Within specific domains of SB, older adults report 3.3 hr in leisure sitting time and 3.3 hr watching TV. There is an association with more time spent in SB as age advances and a trend for older men to spend more time in SB than women.

Conclusion/implications:

Time spent sedentary ranges from 5.3–9.4 hr per waking day in older adults. With recent studies suggesting a link between SB, health, and well-being, independent of physical activity, this is an area important for successful aging.

Limitations:

Different methodologies of measurement and different reporting methods of SB made synthesis difficult. Estimated SB time from self-report is half of that measured objectively; suggesting that most self-report surveys of SB will vastly underestimate the actual time spent in SB.

Over the past 10–15 years, many aspects of total hip arthroplasty (THA) have changed. First and foremost, the patients themselves have changed. Since 1990, the age group that has demonstrated the greatest increase in THA was patients between the ages of 45 and 64. As younger, healthier patients are having surgery, a greater emphasis is being placed on postoperative function, activity, and exercise. The rationale for increased postoperative activity is 2-fold: the obvious cardiovascular benefits of exercise and greater patient desire to return to recreational sporting activities. The purpose of this review is to discuss how recent changes in surgical technique, implant design, and pre- and postoperative rehabilitation have affected postoperative athletic activity for THA patients. Although these topics have been addressed often in the orthopedic literature, to our knowledge no published articles have summarized this information for a targeted audience of rehabilitation specialists.
