Once a week is not enough: Effects of a widely implemented group based exercise programme for older adults; a randomised controlled trial

Objectives: To determine the effects of gymnastics on the health related quality of life (HRQoL) and functional status of independently living people, aged 65 to 80 years. Gymnastics formed part of the More Exercise for Seniors (MBvO in Dutch) programme, a group based exercise programme for older adults in the Netherlands. It has been widely implemented since 1980. Design: Randomised controlled trial with pretest and post-test measurements. Intervention: The exercise programme given by experienced instructors lasted 10 weeks and was given weekly (MBvO1; n = 125, six groups) or twice weekly (MBvO2; n = 68, six groups). The control group (n = 193) was offered a health education programme. Setting: Community dwelling of older people, with a comparatively low level of fitness as assessed with the Groningen Fitness test for the Elderly. Results: No significant effects were found on the HRQoL (Vitality Plus Scale, TAAQoL, and RAND-36) and the functional status (Physical Performance Test and the Groningen Activity Restriction Scale). The MBvO2 group, with a low level of physical activity at baseline, showed the only improvement found on the Vitality Plus Scale (F = 4.53; p = 0.01). Conclusions: MBvO gymnastics once a week did not provide benefits in HRQoL and functional status after 10 weeks. However, participants with a low level of physical activity may benefit from MBvO gymnastics if they participate twice a week. To improve the health of the general public, sedentary older adults should be recruited and encouraged to combine MBvO with the health enhancing physical activity guidelines.

The effect of a forearm/hand splint compared with an elbow band as a treatment for lateral epicondylitis

The aim of the present study was to compare the effect of a new prefabricated Thämert forearm/hand splint with the effect of a simple elbow band as a treatment for lateral epicondylitis. Forty-three (43) patients that met the inclusion criteria were randomly assigned to the elbow band group and the splint group. They wore the orthotic devices for 6 weeks. Outcome measures were obtained at baseline and directly after the intervention. These outcome measures were maximal grip strength on the involved side with a pain scale from 1 to 10 to determine the extent of pain during gripping, and the Patient-Rated Forearm Evaluation Questionnaire (PRFEQ). Analysis of variances with repeated measures, a Mann Whitney test and multiple linear regression analysis were used to compare the two groups. Main effect for time was significant for maximal grip strength and sum scores on the PRFEQ, but no differences between groups were found, even when a distinction between acute and chronic symptoms was made. Change in pain score during gripping did not differ significantly between the groups. A multiple linear regression analysis showed that the use of the splint did not significantly contribute to the prediction of change in maximal grip strength and in overall PRFEQ. The conclusion is that the forearm/hand splint is not more effective than the elbow band as a treatment for lateral epicondylitis.

Exercise and Inflammation in Pediatric Crohn’s Disease

We examined inflammatory cells, cytokines and growth factors in response to acute bouts of moderate intensity continuous exercise and high intensity intermittent exercise in youth with Crohns disease and in healthy matched-controls. 15 patients and 15 controls performed 30 min of cycling at 50% of peak mechanical power (PMP) and 6 bouts of 4×15-s of cycling at 100% PMP. Blood was collected at rest, at the mid-point, at the end of exercise and at 30 and 60 min into recovery. In patients with CD, both types of exercise increased immune cells and GH and decreased IGF-I. Moderate intensity exercise induced a greater increase in leukocytes (p<0.05), neutrophils (p<0.05), lymphocytes (p<0.001), monocytes (p<0.05), IL-6 (p<0.05), IL-17 (p<0.05) and GH (p<0.05) and a similar decrease in IGF-I, compared with high intensity exercise. TNF-α did not change significantly with either exercise. Responses in patients were similar compared with controls; however, in patients monocytes remained elevated significantly longer in response to MICE. Youth with Crohns disease can engage in distinctly different types of exercise without a significant acute exacerbation of inflammation.

A Dutch Version of the Social Support for Exercise Behaviors Scale

We studied the reliability of a Dutch version of the Social Support for Exercise Behaviors Scale, originally developed by Sallis, Grossman, Pinski, Patterson, and Nader, using a sample of 461 older adults between 55 and 65 years of age. Cronbach alpha for the three subscales was calculated, respectively, as .69, .71, and .26, which are lower than the alphas reported in the original study. This may be due to the cultural differences between The Netherlands and the United States and differences between the samples of the two studies.
