INSULIN SENSITIVITY AFTER MAXIMAL AND ENDURANCE RESISTANCE TRAINING

Hansen, E, Landstad, BJ, Gundersen, KT, Torjesen, PA, and Svebak, S. Insulin sensitivity after maximal and endurance resistance training. J Strength Cond Res 26(2): 327–334, 2012—The purpose of the study was to compare the effects of maximal resistance training (MRT) vs. endurance resistance training (ERT) on improvements in insulin levels and glucose tolerance in overweight individuals at risk of developing type 2 diabetes. Eighteen participants with baseline values suggesting impaired glucose tolerance were randomly assigned to 1 of 2 groups. Group 1 engaged in supervised MRT (Bernstein inverted pyramid system: 5 × 3–4, 60–85% 1 repetition maximum [1RM]), 3 d·wk−1 over 4 months, whereas members of group 2 acted as controls. Later, group 2 engaged in supervised ERT (3 × 12–15, 45–65% 1RM), 3 d·wk−1 over a 4 month period with the 2 prebaselines as controls. Both interventions consisted of 8 exercises that included the entire body. Glucose (fasting and 2-hour test), insulin and C-peptide measures were assessed from pre to post in both groups. The MRT led to reduced blood levels of 2-hour glucose (p = 0.044) and fasting C-peptide (p = 0.023) and decreased insulin resistance (p = 0.040). The ERT caused a significant reduction in the blood levels of insulin (p = 0.023) and concomitant positive effects on % insulin sensitivity (p = 0.054) and beta-cell function (p = 0.020). The findings indicate that both MRT and ERT lead to decreased insulin resistance in people with a risk of developing type 2 diabetes; MRT led to a greater increase in glucose uptake capacity (in muscles), whereas ERT led to greater insulin sensitivity, supporting the recommendation of both MRT and ERT as primary intervention approaches for individuals at a risk of developing type 2 diabetes.

Desire, longing and vanity: emotions behind successful return to work for women on long-term sick leave.

OBJECTIVE The purpose of this study is to identify situations and phenomena that have simplified returning to work for women on long-term sick leave. PARTICIPANTS Seven women who were exposed to a relatively large number of risk factors that normally are associated with difficulties in returning to work. METHODS In-depth interviews with qualitative content analysis. RESULTS The analysis indicated four main categories of factors: The Individual, Interactions, Surrounding Resources, and Situations. In each of the main categories structural factors exist and it appears that these have been of significant importance to the women in their return to work. These are presented as Key Factors and they are: clarification of--and the need for--support in the personal process of change; desire, longing, and vanity; respectful interactions between the individual and people in her surroundings; the structure and content of the rehabilitation clinic; the importance of the perceived reality; and the individuals sense of control during the work related rehabilitation process. CONCLUSIONS The results mostly revealed phenomena that have been indicated and described in earlier research studies. However, emotions such as desire, longing and vanity as motivation and driving forces behind a return to work have not been earlier described.

Factors explaining return to work for long-term sick workers in Norway

Purpose. This study investigates factors that will affect the chances of long-term sick workers returning to work. Method. The study is based on a representative sample of persons with mental illnesses and musculoskeletal disorders who received a rehabilitation allowance in Norway in 2002. Their occupational status in 2005 and experiences from the rehabilitation process were charted through their responses to a questionnaire in combination with national register data. Our analytical framework is based on three domains: the medical domain, the domain of authoritative bodies and the production domain (working life), as described by Lindqvist (Att sätta gränser: organisationer och reformer i arbetsrehabiliteringen. Umeå: Boréa; 2000). Results. Our main findings are that earlier work experience, age and other members in household, in addition, to influence over ones own rehabilitation process explains whether workers on long-term sick leave return to work. Furthermore, individual factors such as gender and diagnosis (i.e. musculoskeletal disorder and mental illness) do not explain the probability to return to work. Experience and contact with representatives of the medical, the authoritative bodies and the production domain only explain to a small extent the probability to return to work. It is even interesting to note that regular contact with the social insurance office (SIO) has a negative effect on the probability to return to work. This may indicate that contact with the SIO subjects sick workers to a risk of developing a ‘social insurance career’ to secure their income. Conclusions. The findings show that the medical, the authoritative bodies and the production domain might represent different logics that can pull a sick worker in different directions during the rehabilitation process. However, these different logics do not fully explain, which outcome a rehabilitation process takes. It is important to extend the analysis to include how the individuals respond to these logics during the rehabilitation process.

Change in pattern of absenteeism as a result of workplace intervention for personnel support

The aim was to investigate whether a preventive intervention carried out in a predominantly female workplace, that of hospital cleaners (consisting of a group of 97 women), had any effect on patterns of absenteeism. As a background, a model for analysing complex patterns of absenteeism, including sickness absences, was also developed. A further aim was to study the interactions between different forms of absenteeism. Comparison was made with a reference group consisting of employees in the same job category who only received the customary personnel support. For individuals in the intervention group who were < 42 years of age, total absence due to sickness decreased. In a multiple regression analysis, the contribution from the intervention to the decrease was significant at the 5% level. This change was particularly obvious in those who had a previous history of high absence due to sickness. No clear relationship was shown between short-term absenteeism and the interventions applied. For those who were > 42 years, short-term absence decreased for those who had been in the same jobs for a long time. The combination of increased age and experience showed a tendency to enhance this decline in short-term absenteeism due to sickness. For those > 42 years, and who at the same time have a previous history of high absenteeism, long-term absenteeism due to sickness seemed to be increasing. Increased experience tended to reduce this increase in long-term sickness absence. This combination of different effects possibly indicated the presence of a process of selection which determined who remained in the job as opposed to those who did not. An important conclusion is that different forms of absenteeism need to be looked at in parallel, and at the same time multivariate statistical analysis needs to be carried out to determine the different interactions between the factors.

Self-Related Health, Physical Activity and Complaints in Swedish High School Students

The aim of this investigation was to study self-related health, physical activity and level of exertion, as well as body complaints in Swedish high school students. A total of 993 high school students aged 16–19 years participated in the study. A questionnaire was completed at school and included questions about self-related health, physical activity behavior, type of physical activity/sport, intensity, duration, possible injuries or complaints, and absence from physical training at school, during the last 3 months. The results showed that 26% of the high school students participated in sports on a regular basis. Males reported significantly better health than females (p < 0.0005). A significantly higher number of females participated in physical activities at a lower level of effort (p < 0.0005) and a higher number of males trained at a higher level of effort (p < 0.005). Sixtyone percent reported body pain during the last 3 months, representing a higher number of females than males (p = 0.03). A higher number of females than males reported complaints from the back (p = 0.002), the knees (p = 0.015), the neck (p = 0.001), and the hip (p = 0.015). Females with body complaints reported poorer health than those without complaints. There was a correlation between poor self-related health and a lower level of physical effort (0.219; p < 0.001). The results showed that the prevalence of musculoskeletal symptoms was high in this population and demonstrated a certain association with self-related health. Therefore, it is important to make it easy for adolescents to perform physical activity at school and during their leisure time in order to prevent chronic diseases.

Motivation for lifestyle changes to improve health in people with impaired glucose tolerance

AIM To identify factors that could have motivational significance for lifestyle change to facilitate the reduction of Impaired Glucose Tolerance (IGT) and, consequently, the risk of having type 2 diabetes. METHODS Eighteen people living in a municipality in central Norway participated in the study. A large-scale public health screening study had defined them as people with IGT. The participants took part in a semi-structured interview that focused on four aspects of everyday lifestyle: (1) structure and rhythm, (2) physical health, (3) physical activity and (4) social relations. RESULTS The interviews showed that the participants in the study changed their priorities regarding daily living. Results indicated four domains of motivational factors that appeared as significant for lifestyle changes. The participants attributed great significance to their physical health and were strongly motivated to prevent disease development by improvement of everyday structure and rhythm, reduction of sickness risk, activity level and social relation. Research indicates, however, that lasting lifestyle changes take time and that health care support must be adapted to the individual in light of their social setting. CONCLUSION Persons with IGT appear to benefit from lifestyle changes along four dimensions of motivational significance: Structure and rhythm, Sickness concerns, Activity levels, Social relations. This means that attention needs to be more carefully tailored the individual along these four dimensions than has been the case in traditional health care.

A statistical human resources costing and accounting model for analysing the economic effects of an intervention at a workplace

The study had two primary aims. The first aim was to combine a human resources costing and accounting approach (HRCA) with a quantitative statistical approach in order to get an integrated model. The second aim was to apply this integrated model in a quasi-experimental study in order to investigate whether preventive intervention affected sickness absence costs at the company level. The intervention studied contained occupational organizational measures, competence development, physical and psychosocial working environmental measures and individual and rehabilitation measures on both an individual and a group basis. The study is a quasi-experimental design with a non-randomized control group. Both groups involved cleaning jobs at predominantly female workplaces. The study plan involved carrying out before and after studies on both groups. The study included only those who were at the same workplace during the whole of the study period. In the HRCA model used here, the cost of sickness absence is the net difference between the costs, in the form of the value of the loss of production and the administrative cost, and the benefits in the form of lower labour costs. According to the HRCA model, the intervention used counteracted a rise in sickness absence costs at the company level, giving an average net effect of 266.5 Euros per person (full-time working) during an 8-month period. Using an analogue statistical analysis on the whole of the material, the contribution of the intervention counteracted a rise in sickness absence costs at the company level giving an average net effect of 283.2 Euros. Using a statistical method it was possible to study the regression coefficients in sub-groups and calculate the p-values for these coefficients; in the younger group the intervention gave a calculated net contribution of 605.6 Euros with a p-value of 0.073, while the intervention net contribution in the older group had a very high p-value. Using the statistical model it was also possible to study contributions of other variables and interactions. This study established that the HRCA model and the integrated model produced approximately the same monetary outcomes. The integrated model, however, allowed a deeper understanding of the various possible relationships and quantified the results with confidence intervals.

Self-help and self-help groups for people with long-lasting health problems or mental health difficulties in a Nordic context: A review

Aim: The aim of this review is to provide systematic knowledge of research from Nordic countries about the meaning of self-help and self-help groups when these are used as a concept or method addressing issues related to long-lasting health problems or mental health difficulties. Methods: Included were studies conducted in the Nordic countries that were published between January 1999 and September 2009. These studies investigated self-help and self-help groups addressing issues related to long-lasting health problems. Results: A total of 83 publications met the inclusion criteria. Four major characteristics of self-help were found to be present in the publications: self-help as an intrapsychological process, self-help as an interpsychological or group process, self-help as a coping, individual learning or empowerment process, and self-help as an alternative or complement to medical treatment. Of the 83 studies, 72 publications used a professional treatment perspective for studying self-help and 11 publications used a perspective derived from alternative or complementary therapies. Conclusions: The review shows that most of the research on self-help and self-help groups for people with long-lasting health problems or disability is conducted with an interest to improve the professional healthcare system. That is, the health-promotion strategy is mainly considered in the framework of treatment or care settings. This means that self-help in this context does not challenge the dominant biomedical health model.

To control with health: From statistics to strategy

The main purpose of this study is to develop and test a generic model for workplace health management in organizations. Four private and four public organizations in northern Sweden were selected for the study. A model for health control was developed on the basis of a literature review and dialogues with the stakeholders in the workplaces. The model was then implemented at the workplaces during a two-year period. Interviews with leaders and co-workers were conducted on two occasions and were analyzed using content analysis and the constant comparison method. By using a grounded theory approach, three main categories were found: health closure and other health and working environment indicators, monetary accounting of health related indicators and changes in leadership behaviour and organizational practices. An important result was that the model influenced leadership values more than leadership and organizational methodologies. From the results a model for workplace health management is proposed, incorporating the planning, control, and improvement structures. The purpose of the model is to take health aspects into consideration when deciding organizational structure (work demands, control and social support). The model controls health by using health-related indicators with high frequency measuring whereas workplace health promotion is done in a structured way with a reflective model.

Entrepreneurs’ health – the importance of psychosocial working conditions and individual factors

The purpose of this study is to identify individual characteristics, individual resources and psychosocial working conditions that explain health among micro enterprise entrepreneurs. The study investigated a sample consisting of 139 Swedish entrepreneurs, who individually answered a questionnaire. Hierarchical regression analyses were performed for self-rated health, sickness presence and sickness absence. Relevant predictor variables for self-rated health were age, change competence, job demands (reversed), physical exercise, social activities and social support. For sickness presence (reversed) the predictor variables gender (male), age and job demands (reversed) contributed significantly. None of the predictor variables contributed significantly to sickness absence. One conclusion is that improving entrepreneurs’ health should focus on both individual and organisational measures. Another conclusion is that entrepreneurs’ health might be an underestimated resource for entrepreneurial behavior.
