Effects of work-oriented fitness courses in lumberjacks with low back pain

This prospective controlled study examined changes in fitness, health, and work ability after a work-oriented physical fitness course arranged for lumberjacks experiencing low back pain but being still at work. The 1-week courses were designed to activate exercising during leisure time and consisted of fitness tests, various types of exercise, and lectures. Eighty-seven lumberjacks participated in the courses and 61 subjects served as controls. Questionnaire data obtained before and 1 year after the course were available for 78 (90%) of the course participants and 41 (67%) of the controls. In the intervention group, perceived fitness, health, and work ability improved and ergonomic strain at work decreased. Both groups reported an increased frequency of leisure-time physical activity. There were between- group differences in the development of fitness, health, distress symptoms, and subjective work ability, whereas the changes in physical activity, back and musculoskeletal symptoms, or ergonomic strain did not differ between the groups. In a 6-month follow up, muscle function improved in the intervention group, but no change was observed in aerobic capacity. There was a tendency of the number of back pain-related sickness leaves, but not of their duration, to develop more favorably in the intervention group, when data from the year before and the year after the course were compared.

The influence of body mass index on long-term fitness from physical education in adolescent girls

Background: Physical education (PE) can improve physical fitness; however, little research has evaluated PE's long‐term influence. The purpose is to determine PE's longitudinal effects on fitness in a group of adolescent girls and to determine whether body mass index (BMI) status influenced any potential effects. Methods: Participants were enrolled in daily PE throughout their ninth grade. Data were collected at baseline and at the end of 9th, 10th, and 11th grades. BMI (kg/m²) was classified into Centers for Disease Control and Prevention percentiles. Fitness was estimated from a 3‐stage step test (change in exercise heart rate (HR) indicated improved fitness) and analyzed using repeated measures general linear modeling with adjustments for baseline BMI, baseline age, ethnicity, intervention status, and moderate‐to‐vigorous physical activity outside PE. Results: Complete data were available for 131 girls (61% of sample) who were predominantly African American, 13.8 ± 0.4 years, mean BMI 24.7 ± 6.1 kg/m² at the ninth‐grade baseline. Overall, stage 1 HR (bpm) decreased from baseline to 9th grade (?5.5 ± 1.3, p < 0.0001), baseline to 10th grade (?7.2 ± 1.4, p < 0.0001), and baseline to 11th grade (?7.0 ± 1.5, p < 0.0001). Change differed by BMI status; fitness improvement was significant for normal and overweight, but not obese girls. After 2 years, change in stage 1 HR (bpm) was significantly different between BMI categories: normal‐weight girls versus obese girls (?10.0 ± 3.2, p = 0.002) and overweight girls versus obese girls (?9.3 ± 3.9, p = 0.02). Conclusion: Fitness differences by BMI exist after a PE program in adolescent girls: fitness improved and was maintained in normal‐weight and overweight girls, whereby obese girls had no improvement in fitness.

Physical activity intervention for males with high risk of coronary heart disease: A three-year follow-up

A controlled investigation on the effect of long-term regular physical activity intervention was conducted on 166 males, 35 to 59 years of age, with high risk of coronary heart disease (CHD). Three years following the completion of this study, a follow-up was initiated to determine physical activity habits, additional lifestyle information, and health of the original exercise and control groups. The original cohort was also subdivided into three groups according to the present level of activity. These were also compared for health and selected lifestyle information. One hundred and sixty subjects from the original sample participated in the questionnaire survey. The level of training experienced during physical activity intervention was not maintained by the exercise group at the time of the follow-up investigation. The control group, on the other hand, increased their level of training. The incidence rate of CHD was the same in the original exercise and control groups and was independent of physical activity 3 years following intervention. Skeletal-muscular injuries, however, were observed most frequently in those subjects presently most active. Changes observed in smoking habits and fatty food intake were independent of original and follow-up physical activity levels, although self-evaluation of health and physical fitness was highest in the most active subjects. The results of the questionnaire follow-up suggest that this program of regular exercise did not result in a lasting modification of physical activity habits and had little effect upon other lifestyle measures.     

Physical exercise, body mass index, and risk of chronic pain in the low back and neck/shoulders: longitudinal data from the Nord-Trondelag Health Study

Chronic musculoskeletal pain constitutes a large socioeconomic challenge, and preventive measures with documented effects are warranted. The authors' aim in this study was to prospectively investigate the association between physical exercise, body mass index (BMI), and risk of chronic pain in the low back and neck/shoulders. The study comprised data on approximately 30,000 women and men in the Nord-Tr?ndelag Health Study (Norway) who reported no pain or physical impairment at baseline in 1984-1986. Occurrence of chronic musculoskeletal pain was assessed at follow-up in 1995-1997. A generalized linear model was used to calculate adjusted risk ratios. For both females and males, hours of physical exercise per week were linearly and inversely associated with risk of chronic pain in the low back (women: P-trend = 0.02; men: P-trend < 0.001) and neck/shoulders (women: P-trend = 0.002; men: P-trend < 0.001). Obese women and men had an approximately 20% increased risk of chronic pain in both the low back and the neck/shoulders. Exercising for 1 or more hours per week compensated, to some extent, for the adverse effect of high BMI on risk of chronic pain. The authors conclude that physical inactivity and high BMI are associated with an increased risk of chronic pain in the low back and neck/shoulders in the general adult population.     

The relationship between physical fitness and coronary risk factor profiles in Japanese women

The purpose of this study was to investigate the relationship between physical fitness and coronary risk factor profiles in Japanese women. The subjects were 1,483 women (ages 30 to 69) who participated in a practical health promotion program. After medical examination, physical fitness was evaluated by conducting a symptom limited maximal exercise test by ergometer to measure maximum oxygen uptake (peakVO₂) with an expired gas analyzer. The subjects were classified into 3 groups (high fitness, moderate fitness, and low fitness) according to age and physical fitness level. The results showed that the subjects in higher fitness groups had lower levels in: body mass index (BMI), percentage of body fat, waist-hip ratio, resting blood pressure, and atherogenic index, and higher HDL-cholesterol compared to those in lower fitness group. Even after adjustment for the effects of age and BMI, die subjects in the higher fitness groups had better coronary risk factor profiles. These results suggest that among Japanese women a high level of physical fitness is related to favorable coronary risk factor profiles.

Improving subjective health at the worksite: a randomized controlled trial of stress management training,physical exercise and an integrated health programme

Our objective was to evaluate the effect of 12 weeks of stress management training (SMT), physical exercise (PE) and an integrated health programme (IHP) in a worksite setting on subjective health complaints. To do this, we randomly split 860 employees into the following groups: control (n = 344), PE (n = 189), IHP (comprising physical exercise and health information) (n = 165) and SMT (n = 162). There were no significant effects on subjective health complaints, sick leave or job stress. However, strong and specific positive effects were experienced for the particular goal areas defined for each intervention. The PE group showed improved general health, physical fitness and muscle pain, while the SMT group showed improved stress management. The IHP group showed the strongest effects, affecting most goals set for treatment.     

Weight loss among female health care workers- a 1-year workplace based randomized controlled trial in the FINALE-health study

ABSTRACT: Background Weight management constitutes a substantial problem particularly among groups of low socio-economic status. Interventions at work places may be a solution, but high quality worksite interventions documenting prolonged weight loss are lacking. This paper presents results of an intervention aimed to achieve a 12 months weight loss among overweight health care workers. Methods Ninety-eight overweight female health care workers were randomized into an intervention or a reference group. The intervention consisted of diet, physical exercise and cognitive behavioral training during working hours 1 hour/week. The reference group was offered monthly oral presentations. Several anthropometric measures, blood pressure, cardiorespiratory fitness, maximal muscle strength, and musculoskeletal pain were measured before and after the 12-months intervention period. Data were analyzed by intention-to-treat analysis. Results The intervention group significantly reduced body weight by 6.1 kg (p<0.001), BMI by 2.2 (p<0.001) and body fat percentage by 2.8 (p<0.001). There were no statistical reductions in the control group, resulting in significant differences between the two groups over time. Conclusion The intervention generated solid reductions in body weight, BMI and body fat percentage among overweight female health care workers over 12 months. The positive results support the workplace as an efficient arena for weight loss among overweight females. Trial registration: NCT01015716.

Sportmedizinische Bewegungsberatung bei Arbeitslosen

Although strong evidence suggests that unemployment increases health risks and physical activity results in significant health benefits, the participation rate in prevention programs among unemployed men is still low. For this reason, a sports medical counseling service was implemented at regional job centers in 2006 to refer unemployed persons into local sports for health programs. The participation rate from 741 long-term unemployed persons was analyzed with respect to gender, health, and physical activity status. Women were more active than men (p = 0.038). Among men, physically active persons differed from non-active persons in BMI, activity status, and self-reported health status (p < 0.05). Especially men with lower fitness, health, and activity status could be motivated for more physical activity (p < 0.001). The odds ratio for program participation of men with lower fitness, health, and activity status is 2.8 (95% confidence interval 1.8-4.3) compared to persons with lower risk factors. Sports medical counseling at job centers seems to be a promising and feasible intervention approach.     

Exercise Reduces C-reactive Protein and Improves Physical Function in Automotive Workers with Low Back Pain

INTRODUCTION: Little is known about the effect of exercise on C-reactive protein (CRP) in patients with low back pain (LBP). The aim of the study was to investigate the effects of 8-week exercise intervention on CRP and physical function in automotive workers with LBP. METHODS: Thirteen male workers (40 +/- 6 years) with LBP completed an 8-week multicomponent exercise intervention program which consisted of resistance training, swimming, stretching and hiking. Serum CRP concentration and physical functions were measured at baseline and after 8-week exercise intervention. RESULTS: Compared to baseline, CRP levels decreased by 38% (P = 0.005), back flexibility improved, isokinetic leg strengths increased (all P < 0.05), and back strength tended to increase. CONCLUSIONS: The results of the present study show that CRP levels decrease with exercise in subjects with LBP and physical function improves. This suggests that exercise-related decreases in inflammation in persons with LBP are associated with improvements in physical function.

Improvements in biometric health measures among individuals with intellectual disabilities: A controlled evaluation of the Fit 5 program

BackgroundIndividuals with intellectual disabilities (ID) have poorer health statuses compared to the general population. Actions are needed to address health disparities and promote healthy lifestyles among individuals with ID. Moreover, studies that consider program settings for this population are needed.ObjectiveThe Special Olympics health program, Fit 5, was evaluated to assess effectiveness in improving health measures for individuals with ID. The settings of programs’ implementation were also considered.MethodsFour Special Olympics basketball teams participated as an intervention group, and three teams as a control group, in a study of the Fit 5 program that was implemented during, and as part of, a regular 8-week basketball season. Resting heart rate (RHR) and blood pressure, and height and weight to calculate Body Mass Index (BMI), were measured before and after the program. Differences in pre- and post-measures were compared between the two groups with paired samples t-tests and ANCOVA.ResultsParticipants in the intervention group had significantly greater improvements in resting systolic and diastolic blood pressures (p = 0.02 and 0.03, respectively) and RHR (p = 0.003). BMI increased for both groups; however, the increase in the intervention group was significantly less (p = 0.006). The Special Olympics setting was considered familiar and supportive and effectively reached individuals with ID.ConclusionThe Fit 5 program positively impacts RHR and blood pressure, and could help reduce extents of BMI increases, in individuals with ID when implemented in a common setting. Further investigation of the impact of Fit 5 and similar programs in additional settings is warranted.     

The relationship of health outcomes to improvement in BMI in children and adolescents

OBJECTIVE: To evaluate the clinical outcomes of patients participating in an outpatient program for managing childhood and adolescent obesity. RESEARCH METHODS AND PROCEDURES: Based on a retrospective chart review, 394 physician-referred obese youth (BMI > 95th percentile), 5 to 19 years of age, were treated in an interdisciplinary, family-centered, behavioral weight management program in a hospital-based outpatient setting. Treatment included group exercise, parent education, and behavioral intervention therapies to improve diet and physical activity. RESULTS: A total of 177 (45%) completed the initial phase of treatment (mean duration = 5.6 months). For the completion group, there were significant improvements (all p < 0.001) in weight (-2.0 +/- 4.9 kg), BMI (-1.7 +/- 1.9 kg/m(2)), and BMI z score (-0.15 +/- 0.15), without interfering with growth (height, 2.2 +/- 1.3 cm; p < 0.001). Significant improvement was also found for blood pressure, total cholesterol, low-density lipoprotein (LDL)-cholesterol, triglycerides, insulin, and aerobic fitness. At onset of treatment, 134 (84%) patients had abnormal fasting insulin concentration, 88 (50%) had abnormal total cholesterol, 14 (8%) had abnormal diastolic blood pressure, and 69 (40%) had abnormal LDL-cholesterol. At the end of treatment, a significant proportion of patients with baseline abnormal blood pressure, total cholesterol, and LDL-cholesterol had normal values (p < 0.001). A decrease in BMI z score was associated with significant improvements in insulin and lipid values (all p < 0.05). DISCUSSION: We have demonstrated that a modest decrease in BMI in an ongoing clinical pediatric weight management program is accompanied by significant improvements in related health measures. These results may be helpful in counseling families with overweight children and adolescents.     

Correlation between physical activity, fitness, and musculoskeletal injuries in police officers

In order to explore the correlation between physical activity, fitness, and injury among police officers, a cross section of active-duty members of the Minneapolis Police Department were surveyed about their level of fitness, physical activity, and prevalence of injury and chronic pain within the past year. In the study, officers with the highest self-reported fitness levels were less likely to experience sprains (OR 0.27, 95% CI 0.08-0.88), back pain (OR 0.48, 95% CI 0.09-0.88), and chronic pain (OR 0.21, 95% CI 0.06-0.73) than those who considered themselves less fit. Officers who were the most physically active were about a third as likely to report back pain (OR 0.37, 95% CI 0.10-0.73) and less than half as likely to report chronic pain (OR 0.42, 95% CI 0.19-0.91) as those who engaged in less activity. And officers with a BMI greater than 35 were 3 times more likely to report back pain (OR 3.36, 95% CI 1.17-9.66) than those whose BMI fell in the normal range (18-25). Thus, officers who engage in higher levels of physical activity and are more physically fit have a lower prevalence of musculoskeletal injuries and chronic pain.     

Obesity and cardiovascular disease risk factors in firefighters: a prospective cohort study

OBJECTIVE: Obesity, despite being a significant determinant of fitness for duty, is reaching epidemic levels in the workplace. Firefighters' fitness is important to their health and to public safety. RESEARCH METHODS AND PROCEDURES: We examined the distribution of BMI and its association with major cardiovascular disease (CVD) risk factors in Massachusetts firefighters who underwent baseline (1996) and annual medical examinations through a statewide medical surveillance program over 5 years of follow-up. We also evaluated firefighters' weight change over time. RESULTS: The mean BMI among 332 firefighters increased from 29 at baseline to 30 at the follow-up examination (2001), and the prevalence of obesity increased from 35% to 40%, respectively (p < 0.0001). In addition, the proportion of firefighters with extreme obesity increased 4-fold at follow-up (from 0.6% to 2.4%, p < 0.0001). Obese firefighters were more likely to have hypertension (p = 0.03) and low high-density lipoprotein-cholesterol (p = 0.01) at follow-up. Firefighters with extreme obesity had an average of 2.1 CVD risk factors (excluding obesity) in contrast to 1.5 CVD risk factors for normal-weight firefighters (p = 0.02). Finally, on average, normal-weight firefighters gained 1.1 pounds, whereas firefighters with BMI > or = 35 gained 1.9 pounds per year of active duty over 5 years of follow-up. DISCUSSION: Obesity is a major concern among firefighters and shows worsening trends over time. Periodic medical evaluations coupled with exercise and dietary guidelines are needed to address this problem, which threatens firefighters' health and may jeopardize public safety.     

Improvements in heart health behaviors and reduction in coronary artery disease risk factors in urban teenaged girls through a school-based intervention: the PATH program

OBJECTIVES: We sought to assess the effects of a school-based intervention program on cardiovascular disease risk factors in urban girls. METHODS: We compared heart health knowledge, health behaviors, cardiovascular risk factors, and physical fitness among a group of 442 multiethnic teenaged girls (310 experimental participants vs 132 control participants). Testing was conducted before and after a 12-week program of vigorous exercises integrated with lectures and discussions on diet, exercise, stress, and smoking. RESULTS: Significant differences in body fat, systolic and diastolic blood pressure, heart health knowledge, and whether breakfast was eaten were observed between experimental participants and control participants. CONCLUSIONS: An integrated program of exercise and heart health-related lectures and discussions had a beneficial effect on health knowledge, health behaviors, and onset of risk factors for coronary artery disease among urban girls.
