“…However, after 4 weeks of detraining, only some of the gain in VO 2max remained. The significant increase in VO 2max in our study was not unexpected, because similar increases have been reported by most aerobic-training studies of 16-20 weeks duration in men of similar ages (Hepple, Mackinnon, Goodman, Thomas, & Plyley, 1997;Pickering et al, 1997;Posner et al, 1992). However, the significant increase in leg strength of the aerobically trained men in our study is in contrast to other cross-sectional and longitudinal studies of aerobically trained older men (Dreyer et al, 2006;Hagberg et al, 1989;Sipila, Viitasalo, Era, & Suominen, 1991; Note.…”

“…Leg extension is an adequate measure of strength per se, but not necessarily an adequate measure of functional strength (Sale, 1988). The 21% increase in leg strength found in the current study is substantially less than the increase in strength found after similar periods of high-and low-intensity resistance training in older individuals (Hortobagyi et al, 2001;Posner et al). The greater increase in strength found with resistance-training protocols most likely reflects the higher intensities used with resistance training and the specific nature of the resistancetraining exercise (Macaluso & De Vito, 2004).…”

This study examined the effect of aerobic training on leg strength, power, and muscle mass in previously sedentary, healthy older men (70–80 yr). Training consisted of 30–45 min of cycle ergometry at 50–70% maximal oxygen consumption (VO2max), 3 times weekly for 16 wk, then 4 wk detraining, or assignment to a nontraining control group (n= 12 both groups). Training increased leg strength, leg power, upper leg muscle mass, and VO2maxabove pretraining values (21%, 12%, 4%, and 15%, respectively;p< .05). However, all gains were lost after detraining, except for some gain in VO2max. This suggests that cycle ergometry is sufficient stimulus to improve neuromuscular function in older men, but gains are quickly lost with detraining. For the older population cycle ergometry provides the means to not only increase aerobic fitness but also increase leg strength and power and upper leg muscle mass. However, during periods of inactivity neuromuscular gains are quickly lost.

Purpose:The aim of this study was to compare the predictors of physical activity between urban and rural dwelling Korean older adults. Methods: This study was a cross-sectional descriptive survey. A self-report questionnaire or face to face interviews were used to collect data from 336 older adults (urban: 129, rural: 207) (OR= 0.799, p<.001) were significant factors predicting physical activity in urban elders. Conclusion: These findings provide information that is relevant in designing interventions to enhance physical activity in older adults. There is a need to develop effective mutifaceted physical activity interventions that include reducing psychological barriers such as depression, loneliness.

“…Likewise, endurance training has been examined in elderly people who performed 20 to 40 minutes of exercise for 12 to 16 weeks ranging from low to high intensity (40% to 70% of heart rate reserve). 12,20 The types of training performed by elderly people who are healthy and those who are frail include walking, cycling, and water and land aerobics. Training has been shown to improve maximal oxygen consumption and 6-minutewalk distance as well as measures of health status.…”

Can Elderly Patients Who Have Had a Hip Fracture Perform Moderate- to High-Intensity Exercise at Home?

et al. 2005

Background and Purpose. The majority of patients after a hip fracture do not return to prefracture functional status. Depression has been shown to affect recovery. Although exercise can reduce impairments, access issues limit elderly people from participating in facility-based programs. The primary purpose of this study was to determine the effects and feasibility of a home exercise program of moderate-or high-intensity exercise. A secondary purpose was to explore the relationship of depression and physical recovery. Subjects. Thirty-three elderly people (24 women, 9 men; Xϭ78.6 years of age, SDϭ6.8, rangeϭ64 -89) who had completed a regimen of physical therapy following hip fracture participated in the study. Subjects were randomly assigned to a resistance training group, an aerobic training group, or a control group. Methods. Subjects were tested before and upon completion of the exercise trial. Isometric lower-extremity force, 6-minute-walk distance, free gait speed, mental status, and physical function were measured. Each exercise session was supervised by a physical therapist, and subjects received 20 visits over 12 weeks. The control group received biweekly mailings. The resistance training group performed 3 sets of 8 repetitions at the 8-repetition maximum intensity using a portable progressive resistance exercise machine. The aerobic training group performed activities that increased heart rate 65% to 75% of their age-predicted maximum for 20 continuous minutes. Results. Resistance and aerobic training were performed without apparent adverse effects, and adherence was 98%. All groups improved in distance walked, force produced, gait speed, and physical function. Isometric force improved to a greater extent in the intervention groups than in the control group. Depressive symptoms interacted with treatment group in explaining the outcomes of 6-minute-walk distance and gait speed. Discussion and Conclusion. High-intensity exercise performed in the home is feasible for people with hip fracture. Larger sample sizes may be necessary to determine whether the exercise regimen is effective in reducing impairments and improving function. Depression may play a role in the level of improvement attained.[Mangione KK, Craik RL, Tomlinson SS, Palombaro KM. Can elderly patients who have had a hip fracture perform moderate-to high-intensity exercise at home ? Phys Ther. 2005;85:727-739.] Key Words: Exercise, aerobic performance; Exercise, force production; Hip fractures; Home care services. H ip fracture is a common medical problem that can drastically change the quality of life for the elderly person. More than 300,000 older people are expected to fracture a hip each year 1 at an estimated cost of $5 billion. 2 It has been well established that the majority of patients with hip fracture do not return to prefracture functional status at 1 year after surgery. [3][4][5][6][7] In a study of 120 people, Marottoli et al 5 showed that, 6 months after hip fracture, only 8% climbed a flight of stairs, 15% walked across a room...
