Physical activity in an inpatient setting is often limited to brief periods of walking. For healthy adults, public health agencies recommend a minimum of 150 min/week of moderate intensity exercise. We sought to determine if meeting this activity threshold, in the absence of incidental activities of daily living, could protect skeletal muscle health during bed rest. Healthy older adults (68 ± 2 y) were randomized to 7-days bed rest with (STEP; n=7) or without (CON; n=10) a 2000 step/day intervention. Performing 2018 ± 4 steps/day did not prevent the loss of lean leg mass and had no beneficial effect on aerobic capacity, strength or muscle fiber volume...

Exercise has proven health benefits for older adults independent of age, disability and disease. However, barriers to exercise participation exist, including travel to, and access to, appropriate facilities and programs. Evidence shows that in-home exercise delivered by allied health professionals can improve physical health and prolong independence among individuals with government supported aged care packages. A less costly alternative is program delivery by home care workers. However, effective training for workers and resources to guide the consumer are required...

Despite its well-established benefits, physical activity engagement is low in the adult population; evidence suggests that this is especially a concern for women >60 years. The purpose of this mixed methods study was to explore the feasibility of a 6-week randomized control trial of self-determination theory-based dance and walking programs for older women. Primary outcomes were feasibility measures: recruitment, retention, and satisfaction. Secondary outcomes included self-reported physical activity, behavioral regulations, and psychological needs...

Foreign-born older adults (FBOAs) are at risk for negative health transitions in Canada. Physical activity (PA) enhances health, yet we know very little about the PA habits of FBOAs in Canada. We conducted a mixed-method study in English, Cantonese, Mandarin, Punjabi, and Hindi, with 49 South Asian and Chinese FBOAs in Vancouver, Canada. In total, 49 participants completed surveys; of these 49, 46 wore accelerometers and 18 completed in-depth interviews. Participants' mean daily step count was 7,876 (women: 8,172, men: 7,164, Chinese: 8,291, and South Asian: 7,196)...

Human gait is symmetric and bilaterally coordinated in young healthy persons. In this study, we aimed to explore the differences in bilateral coordination of gait as measured by the phase coordination index (PCI), gait asymmetry, and stride time variability of gait between four age groups. A total of 44 older adults were recruited: nine young-old (age 70-74 years), 26 old (age 75-84 years), nine old-old (>85 years and older), and 13 young adults (age 20-30 years). Subjects walked on a treadmill; walking speed was systematically increased from 0...

Older people with chronic lung diseases and with low physical activity participation rates are at higher risk of morbidity and mortality. This study assessed the feasibility and acceptability of a purpose-designed Internet-based program (ActivOnline) to monitor and encourage exercise and physical activity. Twelve participants with chronic obstructive pulmonary disease or bronchiectasis were recruited (54-84 years). Primary outcome measures were feasibility measured by frequency of program access, and acceptability measured by semistructured interview, system usability scores, and participant perception of benefit...

Older people are less likely to engage in strength training than their younger counterparts, despite the substantial benefits of this form of exercise for preventing and addressing age-related physical decline. In many countries, strength training programs are available for older people yet are undersubscribed. The aim of this study was to identify the factors influencing older people's participation in strength training at gyms and fitness centers to provide insights into potentially effective recruitment and retention strategies for this population...

The purpose of this study was to investigate the relationship between muscle strength asymmetry and body sway while walking. We studied 63 older adult women. Strong side and weak side of knee extension strength, toe grip strength, hand grip strength, and body sway while walking were measured. The relationship between muscle strength asymmetry for each muscle and body sway while walking was evaluated using Pearson's correlation coefficient. Regarding the muscles recognized to have significant correlation with body sway, the asymmetry cutoff value causing an increased sway was calculated...

It is unknown if higher antagonist muscle co-activation is a factor contributing to higher energy cost of cycling in older adults. We determined how age, power output, and cadence affect metabolic cost and lower extremity antagonist muscle co-activation during submaximal cycling. Thirteen young and 12 older male cyclists completed 6-minute trials at four power output-cadence conditions (75W-60rpm, 75W-90rpm, 125W-60rpm, and 125W-90rpm) while electromyography (EMG) and oxygen consumption were measured. Knee and ankle co-activation indices were calculated using vastus lateralis, biceps femoris, gastrocnemius, and tibialis anterior EMG data...
