Our aim was to study the effects of sense of coherence (SOC) on training adherence and interindividual changes in muscle strength, mobility, and balance after resistance training in older people with hip fracture history. These are secondary analyses of a 12-week randomized controlled trial of progressive resistance training in 60- to 85-year-old community-dwelling people 0.5–7 years after hip fracture (n = 45; ISRCTN34271567). Pre- and posttrial assessments included SOC, knee extension strength, walking speed, timed up-and-go (TUG), and Berg Balance Scale (BBS). Group-by-SOC interaction effects (repeated-measures ANOVA) were statistically significant for TUG (p = .005) and BBS (p = .040), but not for knee extension strength or walking speed. Weaker SOC was associated with poorer training adherence (mixed model; p = .009). Thus, more complicated physical tasks did not improve in those with weaker SOC, independently of training adherence. Older people with weaker SOC may need additional psychosocial support in physical rehabilitation programs to optimize training response.

Alzheimer's disease is a chronic illness characterized by clinical cognitive impairment. A behavioral strategy that is being explored in the prevention of Alzheimer's disease is physical activity. Evidence from randomized controlled trials (RCTs) testing the effects of physical activity for cognitively normal older adults supports that physical activity benefits cognitive performance. Evidence from prospective studies supports a protective effect of physical activity with reductions in the risk of cognitive decline ranging from 28% to 45%. RCTs with cognitively impaired older adults also generally support positive effects with greater benefits evident for aerobic interventions. Research examining the potential moderating role of apolipoprotein E (APOE) has yielded mixed results, but the majority of the studies support that physical activity most benefits those who are at greatest genetic risk of Alzheimer's disease. Future directions for research are considered with an emphasis on the need for additional funding to support this promising area of research.

A systematic review of literature was conducted to examine the association between changes in health-related fitness (e.g., aerobic capacity and muscular strength/endurance) and chronic disease risk factors in overweight and/or obese youth. Studies published from 2000–2010 were included if the physical activity intervention was a randomized controlled trial and reported changes in fitness and health outcomes by direction and significance (p < .05) of the effect. Aerobic capacity improved in 91% and muscular fitness improved in 82% of measures reported. Nearly all studies (32 of 33) reported improvement in at least one fitness test. Changes in outcomes related to adiposity, cardiovascular, musculoskeletal, metabolic, and mental/emotional health improved in 60%, 32%, 53%, 41%, and 33% of comparisons studied, respectively. In conclusion, overweight and obese youth can improve physical fitness across a variety of test measures. When fitness improves, beneficial health effects are observed in some, but not all chronic disease risk factors.
