To study the effects of a supervised, intensive (85% of one repetition maximum (1-RM)) 14 week resistance training programme on lipid profile and body fat percentage in healthy, sedentary, premenopausal women.
Twenty four women (mean (SD) age 27 (7) years) took part in the study. Subjects were randomly assigned to either a non-exercising control group or a resistance exercise training group. The resistance exercise training group took part in supervised 45-50 minute resistance training sessions (85% of 1-RM), three days a week on non-consecutive days for 14 weeks. The control group did not take part in any structured physical activity.
Two way analysis of variance with repeated measures showed significant (p < 0.05) increases in strength (1-RM) in the exercising group. There were significant (p < 0.05) decreases in total cholesterol (mean (SE) 4.68 (0.31) v 4.26 (0.23) mmol/1 (180 (12) v 164 (9) mg/dl)), low density lipoprotein (LDL) cholesterol (2.99 (0.29) v 2.57 (0.21) mmol/l (115 (11) v 99 (8) mg/dl), the total to high density lipoprotein (HDL) cholesterol ratio (4.2 (0.42) v 3.6 (0.42)), and body fat percentage (27.9 (2.09) v 26.5 (2.15)), as well as a strong trend towards a significant decrease in the LDL to HDL cholesterol ratio (p = 0.057) in the resistance exercise training group compared with their baseline values. No differences were seen in triglycerides and HDL cholesterol. No changes were found in any of the measured variables in the control group.
These findings suggest that resistance training has a favourable effect on lipid profile and body fat percentage in healthy, sedentary, premenopausal women.

    • "A 14 weeks long study on women with resistance training demonstrated the favourable effect on lipid profile and body fat percentage in healthy, sedentary, premenopausal women [4]. The study showed significant decrease in total body fat and cholesterol [4]. A 17 week research on middle aged obese women with increased physical activity and calorie restriction showed a drop of 5% in fat body weight [6]. "

    ABSTRACT: Background and objective: Obesity itself is believed to be a morbid condition by many and it is also thought to be a cause of many health problems and chronic diseases like type 2 diabetes mellitus, coronary heart diseases. Regular physical exercise has got many health benefits including its effect on metabolism particularly on lipids. The objective of present study is to assess the effect of exercise training on lipid profile. Materials and Methods: We followed up 40 male students of Physical education aged between 18 to 25 years, for the period of nine months. Those with history of inborn errors of metabolism, those having endocrine disorders, those with diagnosed familial hyperlipidemia are excluded from our study. Their lipid profile parameters were measured in the beginning of exercise training period and then at the interval of every 3 months, with the first reading taken as baseline. Result: when we compared the readings with each other as well as with the baseline reading, we found that the levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C) and very Low density lipoprotein cholesterol (VLDL-C) decreased significantly while high density lipoprotein cholesterol (HDL-C) increased as the duration of exercise training period progressed. Significant reduction was also observed in TC/HDL-C ratio as the duration of physical training progressed. Conclusion: Findings of our study suggest that, regular physical exercise has possible effect on improving lipid metabolism as lipid profile improved with increase in duration of exercise training period. Regular physical activity may be associated with decreased risk of chronic diseases like diabetes mellitus type 2, coronary heart disease. KEY WORDS: Exercise training, obesity, lipid profile, chronic diseases.

    • "Substantial evidence exists to suggest that long-term resistance training (RT) alone can promote favorable changes in body composition, muscular strength and endurance, and lipid metabolism thereby having a positive impact on obesity [88]. Other research has demonstrated increases in FFM with resistance training [89]. "

    ABSTRACT: Osteopenia/osteoporosis, sarcopenia, and obesity are commonly observed in the process of aging, and recent evidence suggests a potential interconnection of these syndromes with common pathophysiology. The term osteosarcopenic obesity has been coined to describe the concurrent appearance of obesity in individuals with low bone and muscle mass. Although our understanding of osteosarcopenic obesity's etiology, prevalence, and consequences is extremely limited, it is reasonable to infer its negative impact in a population that is aging in an obesogenic environment. It is likely that these individuals will present with poorer clinical outcomes caused by the cascade of metabolic abnormalities associated with these changes in body composition. Clinical outcomes include but are not limited to increased risk of fractures, impaired functional status (including activities of daily living), physical disability, insulin resistance, increased risk of infections, increased length of hospital stay, and reduced survival. These health outcomes are likely to be worse when compared to individuals with obesity, sarcopenia, or osteopenia/osteoporosis alone. Interventions that utilize resistance training exercise in conjunction with increased protein intake appear to be promising in their ability to counteract osteosarcopenic obesity.

Resistance training was at an intensity of 85 % of one maximal repetition (85 % 1 RM), where one maximal repetition is the maximal load that can be lifted once for a given exercise [41]. "

    ABSTRACT: There is a direct relationship between chronically elevated cholesterol levels (dyslipidaemia) and coronary heart disease. A reduction in total cholesterol is considered the gold standard in preventative cardiovascular medicine. Exercise has been shown to have positive impacts on the pathogenesis, symptomatology and physical fitness of individuals with dyslipidaemia, and to reduce cholesterol levels. The optimal mode, frequency, intensity and duration of exercise for improvement of cholesterol levels are, however, yet to be identified. This review assesses the evidence from 13 published investigations and two review articles that have addressed the effects of aerobic exercise, resistance training and combined aerobic and resistance training on cholesterol levels and the lipid profile. The data included in this review confirm the beneficial effects of regular activity on cholesterol levels and describe the impacts of differing volumes and intensities of exercise upon different types of cholesterol. Evidence-based exercise recommendations are presented, aimed at facilitating the prescription and delivery of interventions in order to optimize cholesterol levels.
