Article: Insulin sensitivity after maximal and endurance resistance training.
[show abstract] [hide abstract]
ABSTRACT: 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.The Journal of Strength and Conditioning Research 02/2012; 26(2):327-34. · 1.83 Impact Factor -
Article: Motivation for lifestyle changes to improve health in people with impaired glucose tolerance
[show abstract] [hide abstract]
ABSTRACT: Scand J Caring Sci; 2011; 25; 484–490 Motivation for lifestyle changes to improve health in people with impaired glucose toleranceAim: 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.Scandinavian Journal of Caring Sciences 08/2011; 25(3):484 - 490. · 0.89 Impact Factor -
Article: Headache and musculoskeletal complaints among subjects with self reported whiplash injury: the HUNT-2 study.
[show abstract] [hide abstract]
ABSTRACT: To evaluate the life-time prevalence of self reported whiplash injury and the relationship to chronic musculoskeletal complaints (MSCs) and headache in a large unselected adult population. Between 1995 and 1997, all inhabitants 20 years and older in Nord-Trondelag county in Norway were invited to a comprehensive health survey. Out of 92,936 eligible for participation, a total of 59,104 individuals (63.6%) answered the question about whiplash injury (whiplash). Among these, 46,895 (79.3%) responded to the questions of musculoskeletal complaints and headache. The total life-time prevalence of self reported whiplash injury was 2.9%, for women 2.7% and for men 3.0%. There was a significant association between self reported whiplash injury and headache (OR = 2.1; 95% CI 1.8-2.4), and chronic MSCs (OR = 3.3; 95% CI 2.8-3.8), evident for all ten anatomical sites investigated. The association was most pronounced for those with a combination of headache and chronic MSC for both men (OR = 4.8; 95% CI 3.6-6.2) and women (OR = 5.2; 95% CI 3.7-7.1). Subjects with self reported whiplash injury had significantly more headache and musculoskeletal complaints than those without, and may in part be due to selective reporting. The causal mechanism remains unclear and cannot be addressed in the present study design.BMC Musculoskeletal Disorders 06/2011; 12:129. · 1.58 Impact Factor -

Article: A County Population of Males Given the Diagnosis of Fibromyalgia Syndrome–Comparison with Fibromyalgia Syndrome Females Regarding Pain, Fatigue, Anxiety, and Depression: The Nord-Trøndelag Health Study [The HUNT Study]
[show abstract] [hide abstract]
ABSTRACT: Objectives: For reasons that remain poorly understood, the fibromyalgia syndrome [FMS] affects women more frequently than men. As a result of this strong female preponderance, the research in FMS mainly has involved females, and studies addressing sex differences are limited. This study explored the prevalence and the relationship of anxiety and depression with pain and fatigue in males given the diagnosis of FMS, and investigated differences between males and females with FMS in an unselected adult county population. Methods: Participants were recruited from the Nord-Trøndelag Health Study [The HUNT Study] in Norway [N = 92,936]. A total of 2,093 participants were included. All reported being given the diagnosis of FMS by their doctor [277 males, 1,816 females]. Results: Significant partial correlations were found in males of anxiety and depression with fatigue, and extremity pain was associated with anxiety. The odds of being female increased by 120 percent when a participant reported pain last year, and by 112 percent with anxiety, whereas it dropped to 85 percent with depression. Conclusion: The role of anxiety and depression in FMS appeared related to gender and should be further investigated.01/2010; 13(3):11-18.
