Abstract
BACKGROUND Previous research indicates that patients exiting a 12-week cardiac rehabilitation program (CRP) have difficulty maintaining an adequate exercise program. Thus, the authors' purpose was to determine if a home-based exercise program would enable patients to maintain/improve their blood lipids, body composition, and functional capacity after exiting the CRP. METHODS Thirty-one patients exiting an initial 12-week CRP were assigned randomly to the home-based (HB) intervention or the standard care (SC) condition. After one home visit, the HB participants (n = 16) were contacted by telephone every other week by CRP staff and completed and returned weekly exercise logs. The SC participants (n = 15) had no contact with the CRP other than to schedule follow-up tests. A third group (n = 17), randomly selected from patients that elected to remain in the center-based CRP (CB) for the same duration, also were examined. All groups underwent exercise testing, fasting blood lipid analysis, and body composition assessment before starting CRP (0M), after 3 months (3M) in a standard CRP, and after 9 months (12M) in either HB, SC, or CB condition (12 months after starting CRP). RESULTS Analysis of variance indicated that there were significant increases in metabolic equivalents and high-density lipoprotein, in all three groups, over time. However, analysis of covariance revealed no significant differences between the HB, SC, and CB groups at 12M for any variable. CONCLUSIONS These data indicate that the HB program was as effective as the CB program at improving/maintaining functional capacity, blood lipids, and body weight/composition. The similar success of the SC group is likely due to their prior experience in CRP and knowledge of follow-up testing. Home-based maintenance program could be offered as a low-cost alternative to CB programs.

Abstract
To determine the extent to which patients with Stage I COPD experience improvements in physical performance and quality of life as a result of exercise training, and to compare these improvements with those seen in Stage I and II patients, 151 patients with COPD underwent a 12-wk exercise program. Outcomes were measured at baseline and follow-up. Physical performance was evaluated by means of a 6-min walk, treadmill time, an overhead task, and a stair climb. General health-related quality of life was assessed in terms of the domains of Social Function, Health Perceptions, and Life Satisfaction. Disease-specific health-related quality of life was assessed with the Chronic Respiratory Disease Questionnaire (CRQ). Six-minute walk distance increased significantly in Stage I (200.5 ft [95% CI: 165.4, 235.7]), Stage II (238.3 ft [143.3, 333.3]), and Stage III (112.1 ft [34.6, 189.6]) participants. Treadmill time increased significantly in Stage I (0.42 min [0.20, 0.64]) and Stage II (0.64 min [0.14, 1.4]) participants. Time to complete the overhead task decreased significantly in Stage I (0.91 s [1.72, 0. 11]) and Stage II (1.39 s [2.66, 0.13]) participants. None of the measures of general health-related quality of life improved in any of the three groups. Participants in Stages I, II, and III all experienced improvements in the CRQ domains of dyspnea (0.72 [0.53, 0.91], 0.47 [0.02, 0.91], and 0.46 [0.05, 0.87], respectively) and fatigue (0.49 [0.33, 0.66], 0.54 [0.20, 0.87], and 0.55 [0.05, 1.05], respectively). These results suggest that all patients with COPD will benefit from exercise rehabilitation. Berry MJ, Rejeski WJ, Adair NE, Zaccaro D.

Abstract
STUDY OBJECTIVES To study the predictive relationships among age, pulmonary function, aerobic fitness, and cognition in people with COPD. DESIGN Observational study conducted during baseline testing with COPD patients who volunteered to participate in an exercise intervention. PARTICIPANTS Older adults (age, 56 to 80 years) with COPD. MEASUREMENTS AND RESULTS Age, depression, education level, aerobic fitness, blood oxygen saturation levels, and pulmonary function were assessed. Participants were randomly assigned to take cognitive tests of (1) fluid intelligence, (2) processing speed and working memory span, or (3) processing speed and inhibition. After controlling for education and depression (F(2,57) = 7.43; r(2) = 0. 21), performance on the 6-min walk (F(1,56) = 15.27; r(2) = 0.17) and age (F(1,55) = 7.52; r(2) = 0.08) were significant predictors of fluid intelligence. On the speed-of-processing task, performance on the 6-min walk (F(1,30) = 8.17; r(2) = 0.20), maximum voluntary ventilation (F(1,29) = 5.81; r(2) = 0.16), and age (F(1,28) = 5.26; r(2) = 0.10) were significant predictors. FVC was a significant predictor (F(1,25) = 6.37; r(2) = 0.18) of working memory span. The ability to inhibit a response was not significantly predicted by any of the variables assessed. CONCLUSIONS In an older COPD sample, age, aerobic fitness, and pulmonary function are predictive of cognitive performance on various tasks. In particular, age and aerobic fitness are predictive of speed of processing, which is a cognitive variable that may itself underlie performance on a majority of cognitive tasks.

Abstract
PURPOSE To examine the validity of the Physical Activity Scale for the Elderly (PASE) among individuals with disability. METHODS A sample of 471 participants (mean age = 71.36) in an epidemiological study of chronic knee pain completed the PASE and self-report measures of knee pain, perceived physical function, satisfaction with physical function, and importance of physical function. A 6-min walk test and an isokinetic assessment of knee strength were also administered. RESULTS PASE scores were significantly correlated in expected directions with performance on the 6-min walk, knee strength, frequency of knee pain during transfer, and perceived difficulty with physical functioning. Gender and age were identified as significant moderators of PASE scores and the scale's construct validity was supported by testing a conceptually driven hypothesis regarding patterns of physical activity. CONCLUSIONS These results support the PASE's validity for the assessment of physical activity among older adults with pain and disability.

Abstract
BACKGROUND Although many of the chronic conditions plaguing older populations are preventable through appropriate lifestyle interventions such as regular physical activity, persons in this age group represent the most sedentary segment of the adult population. The purpose of the current paper was to provide a critical selected review of the scientific literature focusing on interventions to promote physical activity among older adults. METHODS Comprehensive computerized searches of the recent English language literature aimed at physical activity intervention in adults aged 50 years and older, supplemented with visual scans of several journal on aging, were undertaken. Articles were considered to be relevant for the current review if they were community-based, employed a randomized design or a quasi-experimental design with an appropriate comparison group, and included information on intervention participation rates, pre- and post-intervention physical activity levels, and/or pre/post changes in relevant physical performance measures. RESULTS Twenty-nine studies were identified that fit the stated criteria. Among the strengths of the studies reviewed were reasonable physical activity participation rates and relatively long study durations. Among the weaknesses of the literature reviewed were the relative lack of specific behavioral or program-based strategies aimed at promoting physical activity participation, as well as the dearth of studies aimed at replication, generalizability of interventions to important subgroups, implementation, and cost-effectiveness evaluation. CONCLUSIONS Recommendations for future scientific endeavors targeting older adults are discussed.

Abstract
Counseling by health care providers has the potential to increase physical activity in sedentary patients, yet few studies have tested interventions for physical activity counseling delivered in health care settings. The Activity Counseling Trial (ACT) is a 5-yr randomized clinical trial to evaluate the efficacy of two primary care, practice-based physical activity behavioral interventions relative to a standard care control condition. A total of 874 sedentary men and women, 35-75 yr of age, have been recruited from primary care physician offices at three clinical centers for 2 yr of participation. They were randomly assigned to one of three experimental conditions that vary, in a hierarchical fashion, by level of counseling intensity and resource requirements. The interventions, which are based on social cognitive theory and the transtheoretical model, are designed to alter empirically based psychosocial mediators that are known to be associated with physical activity. The present paper describes the theoretical background of the intervention, the intervention methods, and intervention training and quality control procedures.

Abstract
OBJECTIVE To examine the effects of aerobic and resistance exercise on self-efficacy beliefs in older adults with knee osteoarthritis (OA) and to determine whether self-efficacy and knee pain mediated the effects of the treatments on stair time performance and health perceptions. METHODS Measures of self-efficacy, knee pain, stair climbing performance, and health perceptions were collected prior to randomization and again at an 18-month followup in older adults with knee OA who were assigned to 1 of 3 treatment conditions: aerobic exercise, resistance training, or health education control. All analyses were conducted on the intention-to-treat principle. RESULTS Both exercise treatments increased self-efficacy for stair climbing in comparison to the health education control group. Both knee pain and self-efficacy mediated the effect of the treatments on stair climb time, whereas only knee pain mediated health perceptions. CONCLUSIONS The findings suggest that control beliefs and changes in physical symptoms such as knee pain are important outcomes in physical activity programs with patients who have OA of the knee. Moreover, these variables mediate the effects that such programs have on disability and health perceptions.

Abstract
This investigation examined predictors of compliance with exercise therapy in a clinical trial involving older adults with knee osteoarthritis (OA). The study sample was partitioned into tertiles by level of compliance to determine its effect on several clinical outcome measures in the trial (i.e., knee pain, difficulty with activities of daily living, and performance-related disability). The participants (N = 439) first completed all baseline assessments and were then randomly assigned to one of three treatment conditions: health education control, aerobic exercise, or resistance exercise. The two exercise treatments involved a 3-month center-based phase and a 15-month home-based phase. Variables in five categories (i.e., demographic, fitness, health-related quality of life, performance-related disability, and prior exercise behavior) were entered as predictors of attendance and time spent exercising during each session for three different periods of time across the course of the study. Results of these analyses revealed that it was possible to explain more variance for time spent exercising (approximately 40%) during the first 3 months than for attendance (approximately 10%). Furthermore, once participants completed the first 3 months of their training, prior behavior was the strongest predictor of exercise compliance. In most cases, the regression models accounted anywhere from 26 to 46% of the variance in attendance or time spent exercising (7 of the 8 P values < 0.01). In general, demographic, fitness, psychosocial, and disability-related measures did not predict compliance with any consistency across the various phases of the trial. Analysis of the dose-response data suggest that, in the use of aerobic exercise to deter disability in older people with knee OA, consideration should be given to prescribing frequent bouts of activity (at least 3 times each week) of moderate duration (approximately 35 min).

Abstract
This field study used experience sampling procedures to examine the relationship of feeling states and affect to acute bouts of physical activity in women. Participants (N = 86) completed brief affect and feeling state measures (a) in response to random stratified pager tones and (b) before and after acute bouts of vigorous physical activity for 6 weeks. Analysis of averaged difference scores revealed that acute vigorous physical activity was associated with significant improvements in affect and feeling states, particularly in feelings of revitalization. Moreover, within-subject analyses indicated that the effects were moderated by preactivity scores, with the greatest improvements seen when women felt worst before activity.

Abstract
OBJECTIVE To determine the effects of structured exercise programs on self-reported disability in older adults with knee osteoarthritis. SETTING AND DESIGN A randomized, single-blind clinical trial lasting 18 months conducted at 2 academic medical centers. PARTICIPANTS A total of 439 community-dwelling adults, aged 60 years or older, with radiographically evident knee osteoarthritis, pain, and self-reported physical disability. INTERVENTIONS An aerobic exercise program, a resistance exercise program, and a health education program. MAIN OUTCOME MEASURES The primary outcome was self-reported disability score (range, 1-5). The secondary outcomes were knee pain score (range, 1-6), performance measures of physical function, x-ray score, aerobic capacity, and knee muscle strength. RESULTS A total of 365 (83%) participants completed the trial. Overall compliance with the exercise prescription was 68% in the aerobic training group and 70% in the resistance training group. Postrandomization, participants in the aerobic exercise group had a 10% lower adjusted mean (+/- SE) score on the physical disability questionnaire (1.71 +/- 0.03 vs 1.90 +/- 0.04 units; P<.001), a 12% lower score on the knee pain questionnaire (2.1 +/- 0.05 vs 2.4 +/- 0.05 units; P=.001), and performed better (mean [+/- SE]) on the 6-minute walk test (1507 +/- 16 vs 1349 +/- 16 ft; P<.001), mean (+/-SE) time to climb and descend stairs (12.7 +/- 0.4 vs 13.9 +/- 0.4 seconds; P=.05), time to lift and carry 10 pounds (9.1 +/- 0.2 vs 10.0 +/- 0.1 seconds; P<.001), and mean (+/-SE) time to get in and out of a car (8.7 +/- 0.3 vs 10.6 +/- 0.3 seconds; P<.001) than the health education group. The resistance exercise group had an 8% lower score on the physical disability questionnaire (1.74 +/- 0.04 vs 1.90 +/- 0.03 units; P=.003), 8% lower pain score (2.2 +/- 0.06 vs 2.4 +/- 0.05 units; P=.02), greater distance on the 6-minute walk (1406 +/- 17 vs 1349 +/- 16 ft; P=.02), faster times on the lifting and carrying task (9.3 +/- 0.1 vs 10.0 +/- 0.16 seconds; P=.001), and the car task (9.0 +/- 0.3 vs 10.6 +/- 0.3 seconds; P=.003) than the health education group. There were no differences in x-ray scores between either exercise group and the health education group. CONCLUSIONS Older disabled persons with osteoarthritis of the knee had modest improvements in measures of disability, physical performance, and pain from participating in either an aerobic or a resistance exercise program. These data suggest that exercise should be prescribed as part of the treatment for knee osteoarthritis.

Abstract
Participation in a standard-length outpatient cardiac rehabilitation program (CRP) for 3 months is known to result in positive changes in body composition, functional capacity, and blood lipids in patients with coronary artery disease. However, there has been little attempt to compare patients who remain active in a formal CRP for an extended length of >1 year with patients who exit after a standard length of 3 months. Consequently, 50 patients underwent a series of tests including a maximal graded exercise treadmill test, assessment of body composition, and fasting blood lipid analysis, at entry to CRP and after a follow-up period that ranged from 1 to 5 years. All patients participated in a standard multidisciplinary cardiac rehabilitation program for 3 months. Twenty-five patients discontinued participation after 3 months and received no other contact from the program staff until follow-up, whereas 25 patients remained active in the program until follow-up. After statistically adjusting for baseline differences between the groups, significant differences were observed between the extended- and standard-length groups at follow-up for body weight (177 vs 183 lbs), percent fat (22% vs 24%), METS (10.5 vs 8.4), high-density lipoprotein level cholesterol (44 vs 39 mg/dl), total cholesterol/high-density lipoprotein ratio (5.2 vs 6.1), and triglycerides (134 vs 204 mg/dl), respectively. No significant differences in the adjusted means were observed between the groups at follow-up for total cholesterol (209 vs 219 mg/dl) and low-density lipoprotein cholesterol (136 vs 138 mg/dl). Data from this study demonstrate the efficacy of extended participation in CRP on body composition, functional capacity, and blood lipids. Greater efforts need to be directed at retaining patients in low-cost, center-based maintenance programs and at extending monitoring of patients exiting standard length CRPs.

Abstract
The American College of Sports Medicine (ACSM) equation for estimating oxygen consumption (VO2) is often inappropriately applied to non-steady-state treadmill exercise. Therefore, it was the purpose of this investigation to develop an equation to estimate VO2 that could be applied to non-steady-state treadmill exercise in a population of patients with osteoarthritis of the knee, and to assess the generalizability of this equation for estimating VO2peak in patients with cardiovascular disease. Subjects for the investigation were 414 participants in the Fitness and Arthritis in Seniors Trial (FAST), and 362 patients with cardiovascular disease. Results from the FAST subjects showed that the ACSM equation was inappropriate for estimating VO2 during non-steady-state incremental treadmill walking. We developed the following equation (FAST) using speed and the interaction between speed and grade as the predictor variables during treadmill walking: VO2(ml.kg-1.min-1) = 0.0698 x speed(m.min-1) + 0.8147 x grade(%) x speed(m.min-1) + 7.533 ml.kg-1.min-1 The generalizability of the FAST equation for estimating VO2peak was evaluated in the patients with cardiovascular disease. The measured VO2peak of these patients was 23.7 +/- 0.3 ml.kg-1.min-1, whereas the VO2peak values estimated from the FAST equation and the ACSM equation were 24.1 +/- 0.3 and 33.2 +/- 0.5 ml.kg-1.min-1, respectively. No significant differences were found between the measured VO2peak and that estimated from the FAST equation. The VO2peak estimated from the ACSM equation was significantly greater than the measured VO2peak. These results suggest it is more appropriate to use the FAST equation rather than the ACSM equation to estimate VO2 in older patients with either osteoarthritis of the knee or cardiovascular disease.

Abstract
This study examined the relationship between self-efficacy beliefs and pain during the performance of stair climbing and lifting/carrying tasks on speed of movement, ratings of task difficulty, and perceived task ability in a group of patients with osteoarthritis (OA) of the knee. Seventy-nine patients with knee OA completed the tasks in a controlled laboratory setting. Before completing each task, patients' self-efficacy was assessed; following task performance they rated (a) the most intense knee pain experienced, (b) the difficulty of the task, and (c) their perceived ability as they performed each task. Results demonstrated that, even after controlling for physical function, self-efficacy, and knee pain during performance, each contributed significantly to understanding either speed of movement or self-reported ratings of task difficulty and perceived ability.

Abstract
This study investigated the hypothesis that the effects of acute aerobic exercise on feeling states may be influenced by the objective dose of activity, subjective responses during exercise, and preexisting levels of feeling states. College-age women (N = 80) completed baseline measures and were then randomly assigned to 1 of 4 conditions: attention control for 10 min, or exercise for 10 min, 25 min, or 40 min. Levels of exertion and affect were assessed during exercise, and posttesting occurred 20 min following activity. Exercise enhanced revitalization in comparison with the control condition; however, this effect occurred only for participants scoring low to moderate on the pretest. In addition, in-task feeling states predicted postexercise revitalization even after we controlled for the treatment, the pretest, and the Pretest x Treatment interaction.

Abstract
This investigation describes the development and validation of a test battery for evaluating physical activity restrictions (PAR) in patients with knee osteoarthritis (OA). The tasks on the final version of the PAR include (a) a 6-min walk; (b) a stair climb; (c) a lifting and carrying task; and (d) getting into and out of a car. Data from patients with knee OA revealed that the four tasks loaded highly on a single unrotated principal component yielding an alpha internal consistency reliability of 0.92. These data suggest that investigators may choose to use an aggregate score and/or responses from individual tasks. Two week test-retest reliabilities for the four tasks were all in excess of 0.85 and there was support for their concurrent and convergent validity. Specifically, performance on the tasks correlated with time on treadmill, difficulty with self-reported ADLs, and ratings of difficulty following the performance of each task. Additional research is needed on the predictive validity of the measure and its sensitivity to change.

Abstract
This study investigated the hypothesis that the effects of acute aerobic exercise on feeling states may be influenced by the objective dose of activity, subjective responses during exercise, and preexisting levels of feeling states. College-age women (N = 80) completed baseline measures and were then randomly assigned to 1 of 4 conditions: attention control for 10 min, or exercise for 10 min, 25 min, or 40 min. Levels of exertion and affect were assessed during exercise, and posttesting occurred 20 min following activity. Exercise enhanced revitalization in comparison with the control condition; however, this effect occurred only for participants scoring low to moderate on the pretest. In addition, in-task feeling states predicted postexercise revitalization even after we controlled for the treatment, the pretest, and the Pretest x Treatment interaction.

Abstract
Sixteen female breast cancer patients who had been diagnosed (3.0 +/- 1.2 years previous to the study) and undergone surgery, chemotherapy, and/or radiation treatment were randomly assigned to exercise and nonexercise groups. Pre- and post-study measurements were taken for aerobic performance, leg strength, and concentrations of circulating lymphocyte subsets and natural killer cell cytotoxic activity (NKCA). Exercise training consisted of 60 minutes of supervised weight training and aerobic activity three times each week for eight weeks. Although subjects in the exercise groups demonstrated some modest improvement in the various aerobic and strength tests, NKCA and concentrations of circulating T and NK cells were not significantly altered relative to the nonexercise group. This study suggests that moderate exercise over an eight-week period has no significant effect on the function of in vitro natural killer cells in breast cancer patients.

Abstract
OBJECTIVE To develop and validate a knee pain scale (KPS) for use with osteoarthritis (OA) of the knee. METHODS Patients with documented evidence of knee OA completed the KPS and a test battery including measures of physical functioning, physical performance, and depression. Analyses were conducted to confirm the 4-factor structure of the measure, determine alpha reliabilities, assess the test-retest reliability, and examine the construct validity of the KPS. RESULTS Confirmatory factor analysis revealed that the KPS has 4 subscales, including frequency and intensity of pain experienced during both ambulation/climbing and transfer activities. All reliabilities were in excess of 0.80 and the subscales of the KPS shared expected variance with both self-reported and objective indices of dysfunction. CONCLUSION The KPS has good psychometric properties for assessing pain experienced in conjunction with the performance of activities of daily living. Although at present it is a research tool, with further study it should prove valuable in clinical practice as well.

Abstract
This section of the symposium addresses the definition, measurement, and relevance of health-related quality of life (HRQL) to osteoarthritis (OA) of the knee. Emphasis is placed on the multidimensional nature of HRQL and the fact that these measures can be used as either outcome or process variables. Clearly, HRQL has been accepted as an appropriate measure of treatment efficacy (an outcome measure) in most clinical research, augmenting the more traditional measures of morbidity and mortality. However, as this paper demonstrates, HRQL measures constitute important process variables in understanding disability and related concepts that are critical in designing effective therapies for treating knee OA.
