Fifty-five healthy, sedentary, nonsmoking, and nonobese 24- to 26-year-old men who had low plasma concentrations of high density lipoprotein (HDL) cholesterol were selected for a study of the effect of short-term exercise on plasma lipid and lipoprotein concentrations. The participants were randomized into two groups. Of these, 28 were assigned to a 9-week program of submaximal aerobic exercise three times weekly, and 27 were assigned to a nonexercising control group. Changes in physical fitness were assessed by increments in estimated maximal oxygen consumption; this increased by 15% in the exercise group (p less than 0.001) but remained unchanged in the control group. During the study, body weights and skinfold thicknesses of both groups remained essentially unchanged after 9 weeks. There was no significant difference between the trial groups in total cholesterol, HDL cholesterol, calculated low density lipoprotein cholesterol, or in the HDL2 and HDL3 subfractions.

Effects of training and a single session of exercise on lipids and apolipoproteins in hypercholesterolemic men. J. Appl. Physiol. 83(6): [2019][2020][2021][2022][2023][2024][2025][2026][2027] 1997.-To differentiate between transient (acute) and training (chronic) effects of exercise at two different intensities on blood lipids and apolipoproteins (apo), 26 hypercholesterolemic men (cholesterol ϭ 258 mg/dl, age ϭ 47 yr, weight ϭ 81.9 kg) trained three times per week for 24 wk, 350 kcal/session at high (80% maximal O 2 uptake, n ϭ 12) or moderate (50% maximal O 2 uptake, n ϭ 14) intensity. Serum lipid and apolipoprotein (apo) concentrations (plasma volume adjusted) were measured before and immediately, 24, and 48 h after exercise on four different occasions corresponding to 0, 8, 16, and 24 wk of training. Data were analyzed using three-way repeatedmeasures multivariate analysis of variance followed by analysis of variance and Duncan's procedures (␣ ϭ 0.05). A transient 6% rise in low-density-lipoprotein cholesterol measured before training at the 24-h time point was no longer evident after training. Triglycerides fell and total cholesterol, highdensity-lipoprotein cholesterol (HDL-C), HDL 3 -C, apo A-I, and apo B rose 24-48 h after exercise regardless of training or intensity. Total cholesterol, HDL 3 -C, apo A-I, and apo B were lower and HDL 2 -C was higher after training than before training. Thus exercise training and a single session of exercise exert distinct and interactive effects on lipids and apolipoproteins. These results support the practice of training at least every other day to obtain optimal exercise benefits.

The factors responsible for the acute effects of exercise on blood lipids are not well known, and there have been few studies comparing different kinds of exercise in the same population. The concentration of blood lipids was evaluated in this study at the end and at post-24 h of two 14 km/90 min single exercise sessions: continuous exercise (CE) at 44.5 ± 5.6% VO 2max and intermittent exercise (IE) at 39-72% VO 2max , in subjects with high levels of aerobic training. Fourteen male athletes (endurance runners) took part in this study and each completed a 24 h dietary record. The O 2 uptake and CO 2 production were recorded, and blood lactate and blood lipids were measured. The results showed that tri-acylglycerols were not modified by any kind of exercise. Total cholesterol was increased at the end of both exercises: 7.04% for CE (p < 0.001) and 4.23% for IE (p = 0.001). High-density lipoprotein cholesterol was increased at the end of IE: 11.38% (p = 0.03) and low-density lipoprotein cholesterol was increased only at the end of CE: 7.45% (p = 0.006). The increase of lipids for CE was negatively correlated with aerobic fitness indicators (heart rate and %HRmax at lactate threshold), and was positively associated with energy expenditure. For IE, %HRmax and lactate were negatively correlated, and the respiratory exchange ratio was positively correlated,

Training intensity, blood lipids, and apolipoproteins in men with high cholesterol. J. Appl. Physiol. 82(1): 270-277, 1997.-Twenty-six hypercholesterolemic men (mean cholesterol, 258 mg/dl; age, 47 yr; weight, 81.9 kg) completed 24 wk of cycle ergometer training (3 days/wk, 350 kcal/session) at either high (n 5 12) or moderate (n 5 14) intensity (80 and 50% maximal O 2 uptake, respectively, randomly assigned) to test the influence of training intensity on blood lipid and apolipoprotein (apo) concentrations. All physiological, lipid, and apo measurements were completed at 0, 8, 16, and 24 wk. Lipid data were analyzed via two 3 four repeated-measures analysis of variance (~5 0.0031). Training produced a significant decrease in body weight and increase in maximal O 2 uptake. No interactions between intensity and weeks of training were noted for any lipid or apo variable, and no between-group differences were significant before or throughout training. Therefore, intensity did not affect the training response. Regardless of intensity, apo AI and apo B fell 9 and 13%, respectively, by week 16 and remained lower through week 24 (P , 0.0003). Total cholesterol fell transiently (25.5%) by week 16 (P , 0.0021) but returned to initial levels by week 24. Triglyceride, low-densitylipoprotein cholesterol, and high-density-lipoprotein (HDL) cholesterol did not change with training. In contrast, HDL 2 cholesterol rose 79% above initial levels by week 8 and 82% above initial levels by week 24 (P , 0.0018); HDL 3 cholesterol fell 8 and 13% over the same training intervals (P , 0.0026). These data show that changes in blood lipid and apo concentrations that accompany training in hypercholesterolemic men are not influenced by exercise intensity when caloric expenditure is held constant. exercise; hypercholesterolemia; lipoproteins

The effect of weight lifting and running on the plasma lipid profiles of a physically fit 32-year-old hypercholesterolemic male were determined while he adhered to a controlled Phase III American Heart Association diet. The subject followed the same daily menu pattern for the entire test period. He completed four treatment phases: 6 weeks of detraining, 10 weeks of weight lifting, 10 weeks of running, and 10 weeks of weight lifting. The study was designed to closely compare two modes of exercise training for the same duration. A complete lipid profile was analyzed at baseline and every 5 weeks thereafter. Body weight and body fat remained constant throughout the study. Results revealed that running was the only effective treatment in raising high-density lipoprotein cholesterol (HDL-C). A return to weight lifting was associated with a 4 mg % decrease in HDL-C. The controlled low-fat, high carbohydrate, and low cholesterol diet effectively reduced total cholesterol, low-density, and ...
Effect of Physical Training on Lipid Profile in Healthy, Young Males: A Follow Up Study
International Journal of Physiotherapy and Research, 2015
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.

While aerobic training and, to a lesser degree, resistance training are known to reduce blood concentrations of low-density lipoprotein cholesterol (LDL-C), little is known about the effects of a combination of aerobic and resistance training on LDL-C concentrations. The aim of the investigation was to examine the effects of 16 weeks of no exercise, aerobic training or a combination of aerobic and resistance training on lowering blood concentrations of LDL-C. Thirty-eight healthy, previously untrained men (mean age: 25 years and six months) with borderline high blood LDL-C concentrations volunteered to participate in this investigation. Each subject's blood LDL-C concentrations were measured following a nine- to 12-hour fasting period and prior to any exercise. Aerobic training consisted of exercise using a combination of treadmills, rowers, steppers and cycle ergometers. Combined aerobic and resistance training consisted of a combination of aerobic training at 60% of heart rate...

High density lipoprotein (HDL) cholesterol concentrations have been shown to increase with regular endurance exercise and, therefore, can contribute to a lower risk of coronary heart disease in physically active individuals compared with sedentary subjects. Although low HDL cholesterol levels are frequently observed in combination with hypertriglyceridemia, some individuals may be characterized by isolated hypoalphalipoproteinemia, ie, low HDL cholesterol levels in the absence of elevated triglyceride (TG) concentrations. The present study compared the responses of numerous lipoprotein-lipid variables to a 20-week endurance exercise training program in men categorized on the basis of baseline TG and HDL cholesterol concentrations: (1) low TG and high HDL cholesterol (normolipidemia), (2) low TG and low HDL cholesterol (isolated low HDL cholesterol), (3) high TG and high HDL cholesterol (isolated high TGs), and (4) high TGs and low HDL cholesterol (high TG/low HDL cholesterol). A series of physical and metabolic variables was measured before and after the training program in a sample of 200 men enrolled in the Health, Risk Factors, Exercise Training and Genetics (HERITAGE) Family Study. At baseline, men with high TG/low HDL cholesterol had more visceral adipose tissue than did men with isolated low HDL cholesterol and men with normolipidemia. The 0.4% (not significant) exercise-induced increase in HDL cholesterol levels in men with isolated low HDL cholesterol suggests that they did not benefit from the "HDL-raising" effect of exercise. In contrast, men with high TG/low HDL cholesterol showed a significant increase in HDL cholesterol levels (4.9%, PϽ0.005). Whereas both subgroups of men with elevated TG levels showed reductions in plasma TGs (ϷϪ15.0%, PϽ0.005), only those with high TG/low HDL cholesterol showed significantly reduced apolipoprotein B levels at the end of the study (Ϫ6.0%, PϽ0.005). Multiple regression analyses revealed that the exercise-induced change in abdominal subcutaneous adipose tissue (10.6%, PϽ0.01) was the only significant correlate of the increase in plasma HDL cholesterol with training in men with high TG/low HDL cholesterol. Results of the present study suggest that regular endurance exercise training may be particularly helpful in men with low HDL cholesterol, elevated TGs, and abdominal obesity.

The purpose of this study was to investigate the effect of a progressive run training program on lipid and lipoprotein profiles in high school girls. 37 healthy untrained female students were randomly selected as the participants from among the high school girls in Bandar Gaz city. The subjects were randomly assigned into two groups; an experimental group (n=18) with age 15.22±0.22 yr, height 159.81±1.5 cm, weight 58.13±2.86 kg; and a control group (n=19) with age 14.94±0.19 yr, height 159.17±1.4 cm, and weight 53.02±2.06 kg. Rockport walking test was used to calculate every participant's maximal oxygen consumption both before and after the training program. The training intensity was determined via monitoring maximum heart rate. The experimental group participated in the training (progressive run) for 4 weeks, 4 days a week, 31 minutes per session during the first week, 35 minutes per session during the second and third weeks, and 50 minutes per session during the fourth week a...
