Promoting physical activity in a socially and economically deprived community: a 12 month randomized control trial of fitness assessment and exercise consultation.

The main aim of this study was to assess the effects of a fitness assessment and exercise consultation on physical activity over 1 year in non-regularly active participants drawn from a socially and economically deprived community. Of 3000 people invited to volunteer for either intervention, 225 fitness assessment volunteers were randomly assigned to an experimental or control group; 145 exercise consultation volunteers were similarly assigned. Physical activity was measured at baseline, 4 weeks, 3 months (plus an intervention re-test), 6 months and 1 year. Analysis of variance and follow-up Bonferroni analysis showed that, for those not regularly active at baseline, physical activity increased significantly to 4 weeks, was maintained to 6 months but had fallen by 1 year. Only those receiving an exercise consultation significantly increased their physical activity after 1 year. Compared with fitness assessments, chi-square analysis showed that significantly more non-regularly active participants volunteered for an exercise consultation and those receiving an exercise consultation had significantly better long-term study adherence than those receiving a fitness assessment. The study also showed that, contrary to popular opinion, those in a socially and economically deprived community are not 'hard to reach' and respond well to physical activity interventions.

A comparison of physiological responses and rating of perceived exertion in two modes of aerobic exercise in men and women over 50 years of age.

OBJECTIVES: To compare the physiological responses and ratings of perceived exertion to aerobic dance and walking sessions completed at a self selected pace. METHODS: Six women and six men with a sample mean (SD) age of 68 (7) years completed aerobic dance and walking sessions in random order. A treadmill test was performed by each subject from which peak oxygen uptake (.VO(2)) and maximum heart rates (HRmax) were determined. During the aerobic dance and walking sessions, heart rate and .VO(2) were measured continuously throughout. Rate of perceived exertion (RPE) was measured every three minutes throughout the session. RESULTS: The sample means (SD) for %peak .VO(2) were 67 (17)% for the aerobic dance sessions and 52 (10)% for the walking sessions, and the %HRmax sample means (SD) were 74 (12)% for the aerobic dance sessions and 60(8)% for walking sessions. The sample mean (SD) RPE for the aerobic dance sessions was 11(2), and for the walking sessions it was 10(2). CONCLUSIONS: %peak .VO(2), %HRmax, and RPE were significantly higher for aerobic dance than for walking. However, both the aerobic dance and walking sessions were of adequate intensity to improve aerobic fitness in most subjects. Further investigation into the relation between RPE and %peak .VO(2) in a field setting over representative exercise time periods would be useful.

"Walk in to Work Out": a randomised controlled trial of a self help intervention to promote active commuting.

STUDY OBJECTIVE: To determine if a self help intervention, delivered via written interactive materials (the "Walk in to Work Out" pack), could increase active commuting behaviour (walking and cycling). DESIGN: Randomised controlled trial. The intervention group received the "Walk in to Work Out" pack, which contained written interactive materials based on the transtheoretical model of behaviour change, local information about distances and routes, and safety information. The control group received the pack six months later. Focus groups were also conducted after six months. SETTING: Three workplaces in the city of Glasgow, Scotland, UK. PARTICIPANTS: 295 employees who had been identified as thinking about, or doing some irregular, walking or cycling to work. MAIN RESULTS: The intervention group was almost twice as likely to increase walking to work as the control group at six months (odds ratio of 1.93, 95% confidence intervals 1.06 to 3.52). The intervention was not successful at increasing cycling. There were no distance travelled to work, gender, or age influences on the results. Twenty five per cent (95% confidence intervals 17% to 32%) of the intervention group, who received the pack at baseline, were regularly actively commuting at the 12 month follow up. CONCLUSION: The "Walk in to Work Out" pack was successful in increasing walking but not cycling. The environment for cycling must be improved before cycling will become a popular option.

A randomized, controlled trial to study the effect of exercise consultation on the promotion of physical activity in people with Type 2 diabetes: a pilot study.

AIM: To evaluate the effect of exercise consultation on promotion of physical activity in people with Type 2 diabetes. METHODS: Twenty-six sedentary people with Type 2 diabetes were randomly assigned to receive an exercise consultation and standard exercise information (experimental) or standard exercise information alone (control). Exercise consultation is a one-to-one discussion, based on the transtheoretical model, designed to educate, strengthen motivation and develop realistic strategies to promote physical activity. Changes from baseline at five weeks were assessed in (a) stage of exercise behaviour (b) physical activity levels (7-day recall questionnaire and an accelerometer) (c) quality of life (SF-36 Health Survey and 22-Item Well-Being Questionnaire). RESULTS: 82% (9/11) of participants receiving a consultation increased their stage of exercise behaviour compared to 33% (4/12) of controls (chi2 = 5.4, P = 0.02). Physical activity counts/week increased by 4% (1636 067/1696 191) in the experimental group and decreased by 9% (1560 960/1725 510) in controls. A significant difference was recorded for the change in activity counts per week from baseline to follow-up between the experimental and control group (98% CI = 60 673-710 827). The number of participants taking part in sport or leisure activity increased by 55% (6/11) in the experimental group and decreased by 6% (1/12) in controls. Positive changes were evident in the experimental group, compared to controls, in both quality of life questionnaires. CONCLUSION: Exercise consultation is more effective in stimulating exercise behaviour change in the short term than a standard exercise leaflet.

Development of a Scottish physical activity questionnaire: a tool for use in physical activity interventions.

OBJECTIVES: Three studies were undertaken to establish the reliability and validity of the Scottish physical activity questionnaire (SPAQ), developed to aid seven day recall of leisure and occupational physical activity. METHODS: To establish reliability, SPAQs (n = 34) were completed on a Monday and the following Wednesday. Thus each questionnaire measured four identical days. To establish concurrent validity, 94 participants completed a SPAQ and an adapted stage of exercise behaviour change questionnaire. Responses to SPAQ were then analysed by stage of exercise behaviour change. In a further study of criterion validity, 30 volunteers wore a Caltrac motion sensor for four consecutive days, after which they completed a SPAQ. RESULTS: In the first study, total physical activity had a coefficient of repeatability (R) of 53 minutes. Occupational physical activity showed a similar variance (R = 54.6 minutes) but leisure physical activity was more reliable (R = 29.3 minutes). The main variation in occupational physical activity was found to be walking (R = 39.8 minutes). In study 2, a one way analysis of variance showed the expected relation between physical activity and stage of exercise behaviour change, confirming the concurrent validity of SPAQ with the stage of exercise behaviour change model. In study 3, several erroneous recordings affected both SPAQ and the Caltrac results (kcal). After relevant corrections had been made, the correlation between the two measurement devices was 0.52 (p < 0.05). CONCLUSIONS: SPAQ has been shown to be reliable and to hold strong concurrent validity and limited criterion validity. The main limitation in SPAQ appears to be the measurement of occupational walking. It is therefore recommended that further work be conducted to refine the measurement of this physical activity component. It is evident nonetheless that SPAQ can be used with confidence to measure outcomes in physical activity interventions when account is taken of its limitations.

The effects of exercise in a coronary rehabilitation programme.

Twenty-two male and female patients who had recently suffered a myocardial infarction were randomly assigned to a treatment group who participated in a 10-week exercise-based cardiac rehabilitation programme or a routine care group who did not participate in the rehabilitation programme. Physiological and psychological function were assessed before the programme started and after it finished. Results indicated that the treatment group did not improve physiological functioning more than the control group but they did evidence statistically significant improved psychological functioning. This investigation appears to be the first attempt to assess the potential benefits of an exercise-based cardiac rehabilitation programme in Glasgow and supports the suggestion that exercise-based cardiac rehabilitation has psychological benefits.

An holistic approach to recovery from an overuse injury in a games player.

The management of a chronic injury to an international squash player is described. By good physiotherapeutic management and the involvement of an interdisciplinary team it was possible to make gains in the non-playing period. The rehabilitation period included physiological assessment on the basis of which a training programme was devised with target goals set throughout the period. Mental rehearsal of skills was included at all stages. As a result, the player's confidence was maintained and fitness levels improved. The long term prognosis has been good. The model could be applied to any sports injury.
