Physical and psychological functioning of daily living in relation to physical activity. A longitudinal study among former elite male athletes and controls.
BACKGROUND AND AIMS: Physical exercise plays an important role in the prevention and reduction of disabilities in elderly people. The aim of this study was to determine the role of physical activity in the physical and psychological functioning of daily living in a cohort of former elite male athletes representing different sports, and controls of middle and old age. METHODS: Subjects were 664 former elite male athletes (mean age 64.4 years) and 500 controls (62.0 years) in middle and old age. Subjects were mailed "Physical activity and health survey" questionnaires in 1985 and 1995. The primary outcomes the physical and psychological functioning of daily living--were assessed in 1995 using items from the Mini-Finland Health Survey. Logistic regression was used for longitudinal as well as cross-sectional analyses to estimate odds ratios (OR) for poor physical and psychological functioning of daily living in relation to recreational physical activity adjusted for age, sport group, life-style, BMI, mood, chronic diseases, personality characteristics, life-events and socio-economic status. RESULTS: In the longitudinal analysis, low levels of physical activity (lowest MET quintile vs highest quintile) in 1985 (OR 4.91, 95% confidence interval (CI) 2.02-11.9), older age (> or =70 yrs vs under 60 yrs OR 9.93, 95% CI 4.90-20.2), depression (OR 2.03, 95% CI 1.01-4.09) and anxiety in 1995 (OR 2.67, 95% CI 1.34-5.32) increased the risk of poor physical functioning of daily living in 1995, whereas an increase in a physical activity between 1985-1995 (OR 0.89, 95% CI 0.83-0.95) protected against poor physical functioning of daily living. A history of participating in specific types of sports, especially among certain power sports (weight-lifting and track & field throwers) (OR 0.19, 95% CI 0.06-0.60) and team sports (OR 0.34, 95% CI 0.15-0.81) did reveal a significant protective effect against poor psychological functioning of daily living in the longitudinal analysis. CONCLUSIONS: This study suggests that an increase in physical exercise supports physical daily functionality. A specific history of sports participation promotes psychological well-being at an older age.

Weight loss strategies for obese adults: personalized weight management program vs. standard care.
OBJECTIVE: The objective of this study was to evaluate the effect of a 32-week personalized Polar weight management program (PWMP) compared with standard care (SC) on body weight, body composition, waist circumference, and cardiorespiratory fitness in overweight or obese adults. RESEARCH METHODS AND PROCEDURES: Overweight or obese (29 +/- 2 kg/m(2)) men and women (n = 74) 38 +/- 5 years of age were randomly assigned into either PWMP (men = 20, women = 21) or SC (men = 15, women = 18). Both groups managed their own diet and exercise program after receiving the same standardized nutrition and physical activity advice. PWMP also received a weight management system with literature to enable the design of a personalized diet and exercise weight loss program. Body weight and body composition, waist circumference, and cardiorespiratory fitness were measured at weeks 0, 16, and 32. RESULTS: Eighty percent of participants completed the 32-week intervention, with a greater proportion of the dropouts being women (PWMP: 2 men vs. 7 women; SC: 2 men vs. 4 women). At 32 weeks, PWMP completers had significantly (p < 0.001) greater losses in body weight [6.2 +/- 3.4 vs. 2.6 +/- 3.6 (standard deviation) kg], fat mass (5.9 +/- 3.4 vs. 2.2 +/- 3.6 kg), and waist circumference (4.4 +/- 4.5 vs. 1.0 +/- 3.6 cm). Weight loss and fat loss were explained by the exercise energy expenditure completed and not by weekly exercise duration. DISCUSSION: More effective weight loss was achieved after treatment with the PWMP compared with SC. The results suggest that the PWMP enables effective weight loss through tools that support self-monitoring without the requirement of more costly approaches to program supervision.

Rural-urban differences in health and health behaviour: a baseline description of a community health-promotion programme for the elderly.
STUDY OBJECTIVE: To (1) describe the setting and design of the Good Ageing in Lahti Region (GOAL) programme; (2) by using the baseline results of the GOAL cohort study, to examine whether living in urban, semi-urban, or rural communities is related to risk factors for chronic diseases and functional disability in ageing individuals. DESIGN: The baseline data of a cohort study of ageing individuals living in three community types (urban, semi-urban, rural). Data were collected by two questionnaires and laboratory assessments. SETTING: Fourteen municipalities in the Lahti region (Päijät-Häme County) in Finland. PARTICIPANTS: A regionally and locally stratified random sample of men and women born in 1946-50, 1936-40, and 1926-30. A total of 4,272 were invited and 2,815 (66%) participated. MAIN RESULTS: Elevated serum cholesterol, obesity, disability, sedentary lifestyle (<2 times/week walking), and high fat intake were more prevalent in rural vs. urban and semi-urban communities. After adjustment for sex, age, education, obesity, diet, physical activity, smoking, and alcohol use, rural communities remained the only community type with increased (p<0.05) probability for high BMI (OR 1.33) and high waist circumference (OR 1.43). CONCLUSIONS: The unfavourable health and lifestyle profile, together with an old population, makes health promotion for elderly citizens a special challenge for rural communities such as those in Päijät-Häme County, Finland. Most, if not all, of the differences in health between the three community types were explained by educational background, physical activity, and smoking.

Serum basal hormone concentrations and muscle mass in aging women: effects of strength training and diet.
This study examined the effects of strength training and diet on serum basal hormone concentrations and muscle mass in aging women. Fifty-one women age 49 to 74 y were divided into two groups: strength training and nutritional counseling (n = 25), and strength training (n = 26). Both groups performed strength training twice a week for 21 wk. Nutritional counseling was given to attain sufficient energy and protein intake and recommended intake of fat and fiber. We found that the cross-sectional area of the quadriceps femoris increased by 9.5 +/- 4.1% in the nutritional counseling group versus 6.8 +/- 3.5% in the strength training only group after training (P < 0.052). Nutritional counseling evoked dietary changes such as increases in the proportion of energy from protein and the ratio of polyunsaturated and saturated fatty acids. Strength training increased testosterone and testosterone/sex hormone-binding globulin ratio after the first half of training, but these returned to baseline values at the end of the entire training period. Changes in serum basal hormone concentrations did not differ between the groups. Our results support the conclusion that nutritional counseling can contribute to the increase in the muscle cross-sectional area during prolonged strength training in aging women.

International Physical Activity Questionnaire: Validity against fitness.
PURPOSE: This study was conducted to criterion-validate the short format of International Physical Activity Questionnaire (IPAQ) against health-related fitness. METHODS: Participants included 951 men, aged 21-43 yr. VO2max by ergometer was used to measure cardiorespiratory fitness. Muscular fitness tests included the number of sit-ups, push-ups, and squats performed during 60 s. Physical activity was assessed from IPAQ by categories for health (health-enhancing physical activity (HEPA)) and by calculating total and vigorous MET-hours per week. The participants were classified in five groups of almost equal size by the IPAQ outcomes. Moreover, the frequency of vigorous activity was assessed by one precoded question (single-item question on leisure-time vigorous physical activity (SIVAQ)). RESULTS: The mean fitness improved from the first through the fourth IPAQ group. VO2max in the most active IPAQ group, however, was lower than in the fourth group (P < 0.05), both with HEPA categories and vigorous METs as the outcome. In contrast, the weekly frequency of vigorous physical activity showed a positive association with fitness through all six categories. The 65 sedentary (according to SIVAQ) and unfit individuals who belonged to the highest 20% (by IPAQ total METs) were older (30.6 +/- 5.1 vs 28.9 +/- 3.8, P = 0.02), more obese (waist 93 +/- 12 vs 89 +/- 10 cm), more often current smokers (59.4 vs 42.0%; P = 0.03), and less educated (<12 yr of education 70.8 vs 52.0%; P = 0.02), compared with the others in the highest IPAQ group. CONCLUSIONS: Almost 10% of young men had poor fitness and apparently low physical activity, but they reported very high physical activity by IPAQ. An evident need therefore exists to develop IPAQ further to solve the apparent overreporting by a considerable proportion of sedentary individuals.

Association of the IL6-174(G/C) polymorphism with C-reactive protein concentration after weight loss in obese men.
Elevated plasma concentration of C-reactive protein has emerged as an important predictor of future cardiovascular diseases and metabolic abnormalities in apparently healthy individuals. Obese individuals tend to have elevated C-reactive protein concentrations. Weight loss induces a change in this protein, and single nucleotide polymorphisms in regulating genes might affect this change, since C-reactive protein concentration is known to be approximately 40-50% heritable. Our aim was to study the association between the IL6 -174(G/C), IL1B +3,954(C/T) and CRP +1,059(G/C) single nucleotide polymorphisms, and CRP concentrations in obese men during a weight reduction program. We genotyped 72 obese men who had participated in a weight reduction program. Their C-reactive protein concentrations, interleukin-6 levels and fat mass were determined at two time points: at baseline and after weight reduction (after 2 months). After weight reduction, the mean weight loss was 14.3 kg. Median C-reactive protein concentrations decreased, after weight reduction, from 1.72 to 1.22 mg/l (p < 0.02). The baseline C-reactive protein concentration did not differ between the IL6-174(G/C) genotypes, but after weight loss, concentrations differed (p = 0.03 Kruskal-Wallis test); the highest concentration was found in the CC genotype (CC 1.01 versus GG 1.93 mg/l, p = 0.007 ANOVA post-hoc test). This change in concentration was associated with the IL6-174(G/C) genotype (p = 0.01, Kruskal-Wallis test), being least in the CC genotype. The other single nucleotide polymorphisms studied were not associated with CRP concentrations. Our results show that, at baseline, there is no difference in C-reactive protein concentrations among the different IL6-174(G/C) genotypes, but after weight loss the CC genotype is associated with highest C-reactive protein concentrations, resulting from the fact that C-reactive protein seems not to decrease with weight loss in this genotype.

Effects of strength training and nutritional counseling on metabolic health indicators in aging women.
PURPOSE: Effects of strength training (ST) and nutritional counseling (NC) on metabolic health indicators were examined in 50 aging women. METHODS: Subjects performed ST for 21 weeks. NC was given to obtain sufficient energy and protein intake, and recommended intake of fat and fiber. RESULTS: NC increased intake of protein and polyunsaturated fat by 4.5% and 10.7% and decreased intake of saturated fat by 18.3%. Serum concentrations of total cholesterol (TC), LDL-cholesterol (LDL-C), total and HDL-cholesterol (HDL-C) ratio and triacylglycerols (TAG) decreased, and serum HDL-C increased in all subjects after ST. Respectively, systolic and diastolic blood pressure and serum insulin concentration decreased in all subjects. NC contributed to the decreases in levels of serum LDL-C after the first half of ST and serum TC and HDL-C ratio during both ST periods. Changes in serum TAG concentrations correlated positively with intake of carbohydrates, and negatively with monounsaturated fat in all subjects. Respectively, changes in serum TC levels were related to protein intake, and changes in serum HDL-C to intake of fat, and inversely to carbohydrate and protein in all subjects. Relationships between serum TC and HDL-C levels and protein intake were only observable in the ST+NC group. CONCLUSIONS: The long-term ST had favorable effects on serum lipids, lipoproteins, insulin concentration, and blood pressure. However, NC further contributed to positive changes in serum lipids and lipoproteins.

Health psychological theory in promoting population health in Päijät-Häme, Finland: first steps toward a type 2 diabetes prevention study.
In public health promotion, behavioural science theories and theory-based methods should be translated into practical strategies that fit environmental conditions and are feasible for implementation. In this article, an effort to meet this challenge is presented. As a starting point we describe the conditions for development and success of the previous generation of public health promotion programmes in Finland. However, changes both in the population structure and in the population health bring new demands for programme development. We consider possibilities offered by health psychology and give a practical example of how theories and theory-based methods are applied in a community programme for type 2 diabetes prevention implemented in the Finnish primary health care.

Dairy products, meat and sports performance.
Creatine supplementation improves repetitive, short-term performance. It has not been shown that exclusion of meat from the diet would impair repetitive short-term performance. In contrast, reduction of protein intake and a concomitant increase of carbohydrate intake during a period of 3-5 days improves anaerobic (2-7 minutes) performance. The protein intake in a mixed or lacto-vegetarian diet is adequate even for elite athletes, providing that energy requirements are met. Many dietary supplements have been suggested to increase muscle mass and/or to decrease fat mass. Although the effects of conjugated linoleic acid on body composition in athletes are not clear, some positive findings in untrained, obese individuals call for more studies. Strenuous training may impair immune function and increase the susceptibility to infections. Exclusion of meat from the diet does not seem to have adverse effects on immune function. Glutamine supplementation (>3-6 g/day) may improve immune function, but more studies are needed. Similarly, more studies on the possible effects of whey protein and probiotic supplementation on immune function and performance in physically highly active individuals are warranted. Vitamin and mineral balance are not usually a problem among athletes. Notable exceptions may be calcium and iron in some females. Increased calcium intake in athletes with hormonal and menstrual disturbances could theoretically help in maintaining bone status; however, no data are available. A diet with meat may help in maintaining adequate iron stores.
