EFFECTS OF A CORPORATE FITNESS PROGRAM UPON EMPLOYEES OF DIFFERENT AGE RANGESMELLO, A.
FEDERAL UNIVERSITY OF RIO DE JANEIROIntroduction: Competitiveness of globalized markets demands, besides quality products, the attention of business companies to the environment, safety and health, differentials of great relevance. Among many initiatives, companies have implemented corporate fitness programs aiming the health and the fight against their employees’ chronic degenerative diseases (OPS/OMS, 2005), promoting decrease in absenteeism and in early retirement. In Brazil, Petrobras – Petróleo Brasileiro S/A, in its CENPES unity located in Rio de Janeiro, offers a physical conditioning program (bodybuilding, gymnastics and stretching) to its employees at the Espaço Bem-Estar wellness center.
Methods: The aim of the present study was to investigate possible impacts on the employees’ health who participated in the program,
according to four different age ranges. The sample consisted of 107 users of both genders and the following variables were investigated:
Weight, Body Mass Index (BMI), Fat Percentage (%Fat), Lean Body Mass (LBM), Flexibility and Maximum Volume of Oxygen (VO2maximum). Individuals were assessed in two moments: 1- Before the beginning of the activities in the program and 2- After six months of enrollment. The Exploratory Data Analysis technique was applied to the treatment of rough data and verification of the adherence variables to the normal curve (NIST/SEMATECH, 2006). The parametric t-test, two paired samples for the means, was applied for comparison of the means and identification of the differences. Statistical analysis was conducted using the Statistica 6.0, R 2.4.1 and Microsoft Excel 2003 softwares.
Results: Frequency distribution demonstrated the following behavior: between 20x≤30 years of age were 22.43% of the participants, between 30x≤40, 29.91%, between 40x≤50, 38.32% and over 51, 9.35%. Results indicated that at the age range of 20x≤30 there was an increase in LBM and in Flexibility in the comparative analyses conducted before and after six months in
the program at a 5% significance level. In 30x≤40 there was a reduction in %Fat and increase in Flexibility. The 40x≤50 age range was the most significant in the study because all variables underwent positive changes, except for Flexibility. Over 51 years of age it was observed an increase in VO2maximum.
Discussion: The results of the study showed that the fitness program resulted in benefits to the employees’ health, be it in the LBM increase, %Fat decrease, Flexibility increase or VO2maximum, but benefits may vary according to age ranges. Youths tend to improve Flexibility more, whereas the employees over 40 improve VO2maximum more.

CORPORATE FITNESS AND NUTRITION AS AGENTS IN THE REDUCTION OF RISK FACTORS FOR NON-TRANSMISSIBLE
CHRONIC-DEGENERATIVE DISEASESMELLO, A.
FEDERAL UNIVERSITY OF RIO DE JANEIROIntroduction: Public institutions and business companies are concerned about non-transmissible chronic degenerative diseases (NTCDD) as arterial hypertension, cardiovascular diseases and diabetes mellitus. Petrobras, a Brazilian company of oil and gas, has created policies of prevention and control of its employees’ health and founded the Center for Health Promotion/ CHP [Centro de Promoção de Saúde] in its main building in Rio de Janeiro, integrating fitness performed every week and regular food guidelines. The aim of this study was to verify possible alterations in the risk factors for NTCDD in groups of participants in the program at the CHP after the period of a year of activities, according to the week frequency to the program.
Methods: The functional and biochemical profiles of a sample composed of 357 employees were assessed, selected according to the presence of risk factors for NTCDD through an annual medical exam. The sample was divided into three groups: employees with frequency (F) to the program of physical exercise ≥ twice a week (G1, n=59); F = once a week (G2; n=115); and assessed employees who did not join the program (G3; n=215). All were submitted to the initial anthropometric and nutritional assessment but only G1 and G2 had all the variables re-assessed. Total body mass, relative body fat (%F), waist perimeter (WP) were assessed. We considered hypertensive individuals those who presented systolic blood pressure (SBP) ≥ at 140mmHg, and/or diastolic blood pressure (DBP) ≥
at 90mmHg. The biochemical variables were composed by the assessment of fast glycemia and determination of the lipid profile (triglycerides, total cholesterol, LDL and HDL). We determined the prevalence of the Metabolic Syndrome (SM) according to criteria established by the American Heart Association (2005). For the statistical analysis we used the two way-ANOVA in the SPSS 13.0 program, with 0.05 significance level.
Results and Discussion: As regards the lipid profile, we observed a reduction in all the assessed fractions where were highlighted the
decrease in LDL (G1 males: 139.4 vs. 112.9 mg/dl and G1 females: 130.6 vs. 117.7 mg/dl); (G2 males: 133.5 vs. 117.8 mg/dl and G2 females:
134.9 vs. 103.7 mg/dl) (p 0.05); G3: (G3 males: 134.5 vs. 122.3 mg/dl and G3 females: 123.1 vs. 117.3 mg/dl (p 0.05). We observed the maintenance of the MS percentage among the females in G2, and a statistical significant increase in the female participants in G3 (50% vs. 100%). Among males, there was a decrease in MS in G1 (50% vs. 39%) and an increase with statistical significance in G3 (50% vs.
100%). As regards the glycemic profile, there was a good control of the levels of serum glucose, as in G1 as in G2, and a tendency of increase in G3. There were statistically significant reductions in SBP, DBP, %F and WP in physically active individuals. Even with low weekly frequency to the fitness and nutrition program participants obtained benefits in the reduction of risk factors for NTCDD.

ELDERLY WORKERS IN PHYSICALLY DEMANDING JOBS: HOW DO THEY MANAGE?JEBENS, E., MEDBØ, J.I., MAMEN, A., KNUTSEN, O.
NATIONAL INSTITUTE OF OCCUPATIONAL HEALTHIntroduction: Work in the construction industry is physically demanding and influence the workers’ physical and psychological resources.
Musculo-skeletal disorders constitute the most common diagnose for disability pensions in the trade. The construction industry is the second largest branch for disability retire¬ment for the age group 60–64 yr. This supports the concept that may be called the “strenuous work hypothesis”. Senior construc¬tion workers that report lasting health problems or feel they are so worn out that their work ability is considerably reduced, have the largest tendency to retire early.
Physical ability is reduced by age. A common and important misunderstanding is that workers with physically demanding tasks assume that they maintain their physical work ability through their work. This may not be correct. Therefore, elderly workers may be at disadvantage in physically demanding job.
The purpose of this study was to examine conditions that may retain the seniors (50+ yr) in working life until they reach the age of normal retirement of 67 year (national insurance).
Methods: First a survey (questionnaires) was carried out among all employees in a medium-sized construction company (n = 100). Thereafter 40 construction workers (20 above 45 yr, 20 below 30 yr) were tested for muscular strength, cardio-respiratory fitness, and body fatness. Moreover, 18 of the older and 12 of the younger workers were followed for 1 h each during their normal work while oxygen uptake and heart rate were measured continuously by automatic analysers.
Results Having good health / not being worn out was reported as the most important requirement for staying in work to normal age of retirement. Moreover, most of the workers stated that the work was medium to very strenuous, that they had demanding working positions and that they had daily handling of tools and equipment weighing from 1 to 45 kg. They reported varying degrees of pain and duration of pain in neck, upper and lower back, shoulders, arms, hands, hips and knees.
The group of young workers had a higher VO2-max than the older group: 53±8 vs. 41±6 ml kg-1 min-1. For both groups the work taxed on average 31% of VO2-max and 53% of HR-max. Peak load for a few minutes duration was 54±12% of VO2max and 71±9% of HR-max.
14 ANNUAL CONGRESS OF THE EUROPEAN COLLEGE OF SPORT SCIENCETH Wednesday, June 24th, 2009 Discussion: For both age groups VO2-max was typical for relatively untrained persons of their age, suggesting that their work did not improve their fitness. During work both groups taxed their aerobic power similarly and equal to the internationally accepted level of a mean of 30 % of max aerobic power during an 8 h working day. These data suggest that elderly workers, when given the possibility, may adjust the physical demands to a level they can sustain. However, individual values suggest that for some unfit senior workers the aerobic demand may exceed the proposed upper limit.
DO PEOPLE ON LONG TERM SICK LEAVE EXPERIENCE AN INCLUDING WORKING LIFE?BARSNES, B., MAGNUSSEN, L.H., RÅHEIM, M.
SOGN OG FJORDANE UNIVERSITY COLLEGE AND UNIVERSITY OF BERGENIntroduction: During the last decades, many countries have experienced increasing numbers of people on disability pension and longterm sick leave, despite economic growth and expanding health care systems (Ahlgren and Hammerstrøm, 1999.) In Norway, official reports have investigated the subject to search for explanations and solutions (NOU, 2000). An agreement towards a common responsibility for an including working life has been signed by the Norwegian government and the employee and employers organizations (Arbeids- og velferdsetaten, 2008). The aim of our study is to provide an insight into how people on sick leave experience the cooperation with their employer, their doctor and the governing authorities.
Methods: Focus groups were used for the interviews (Kvale, 1996). The interviews were a part of a larger intervention study at a workplace including 60 employees on long-term ( 6 weeks) sick leave. Twenty-five of the employees were asked to participate in the focus groups. Seventeen responded positively, and were divided into three groups.
Preliminary Results: Most of the participants were satisfied with the way their employer supported them during their period of sick leave, but participants with non-specific disorders (no diagnosis) and participants with a psychiatric diagnosis expressed problems in communicating with their employer.
The views of the doctors’ involvement were divided. Some participants expressed very high regards for their doctors, while others complained about them being hard to reach and difficult to communicate with.
The Norwegian Labour and Welfare Services (NAV) mainly received negative reviews, with the participants expressing that they were offered little help. For instance they had to figure out their own rights and remember to fill out the correct forms at the appropriate times on their own.
Discussion: More knowledge is required at the workplaces for employers to better handle employees with non-specific disorders or a psychiatric diagnosis. Social support at the workplace has been shown to be an important factor for job satisfaction, and the opposite might discourage motivation staying in or returning to work (Drabløs, 1993).
For both doctors and officers at NAV a focus on individual communication skills and attitudes should be emphasized (Magnussen et al, 2007). The focus group participants in the present study also suggested that there should be advisers at NAV designated to helping people on sick leave, and that those advisers should be separate from the caseworkers.
