Accelerated Muscular Development Programs
Strength training with weights is not just for Mr. Universe wannabes. Anyone, old or young, male or female, who wants more strength and endurance can benefit. Well-toned muscles can help in all your daily activities, whether it's carrying groceries, climbing stairs, doing laundry, or changing a flat tire. Strength training can also help prevent osteoporosis and build muscle, even in elderly people. This is important because as people get older, they tend to lose muscle mass and tone. Even people in their 80s and 90s can greatly increase strength through weight training. Another benefit of weight training is that well-toned and larger muscles burn more calories even when you are doing absolutely nothing. So a regular weight lift-
This young man identified that following the camp programme, he had developed a range of skills that enabled participation in more lifestyle physical activity (increasing every day activities such as walking to school, taking the stairs) and strongly pursued the sports that he felt he was good at. He also reported that the programme had encouraged and helped him understand training principles, which led to participation in weight training and cardiovascular training to
Alternative 31P MRS methods can assess the mitochondrial function by measuring the recovery of the skeletal muscle phosphocreatine (PCr) pool following its depletion by well defined isometric exercise (Arnold et al. 1984 Kemp & Radda 1994 Radda et al. 1995 Newcomer & Boska 1997). This process is coupled with recovery of basal skeletal
In anaerobic exercise, consumed energy is derived from anaerobic glycolysis and lactate production (anaerobic resistance training). In this type of exercise, only small groups of muscles or solitary muscles contract, for example in weightlifting, resistance exercises, muscle strengthening exercises, etc.
As the result of the increased cardiovascular risk in diabetic patients, exercise stress testing is vital to identifying blood pressure responses, arrhythmias, heart rate responses, and risk stratification in these patients. Ideally, patients need to burn a minimum of 1000 calories weekly with aerobic exercising and participate in resistance training. This should be achieved with a minimum of three sessions a week, with aerobic exercising gradually increasing to 45 minutes for maximum benefit. Each session should be preceded by a warm-up period and conclude with deceleration activities to allow for gradual transition from the higher demands of the accelerated phase of the workout (12).
Regular physical activity is associated with changes in body composition with a reduction in body fat, increase in muscle mass, and maximal oxygen uptake in healthy individuals insulin sensitivity is closely correlated to these factors. Corresponding results are obtained in patients with diabetes type 2 who engage in a structured exercise program. Improvements of insulin sensitivity are independently correlated to a reduction in abdominal obesity and an increase in muscle cross-sectional area (10). The benefits of exercise, however, are only maintained for short periods of time they attenuate 3 to 6 days after the last exercise session stressing the importance of persistent lifestyle changes (11-13). By adding resistance training to aerobic exercise muscle mass may be increased, particularly in elderly patients who tend to loose muscle mass as a result of aging (10,14).
Despite the beneficial effects that were mentioned above, physical activity may also be accompanied by unwelcome effects and incur risks for the exercising person, especially if certain conditions and safety rules are not fulfilled. These risks (apart from the already mentioned hypoglycaemia), are sudden death, serious arrhythmias, myocardial infarction etc., especially in those with underlying heart disease (very common in diabetic persons). In diabetic patients specifically, certain diabetic complications can restrict physical activity levels or even preclude some forms of muscular activity. For example, patients with neuropathy should avoid long-term walking and exercises that entail jumping (risk of musculoskeletal trauma) those with nephropathy should be advised to avoid intense exercises (risk of increase in proteinuria) and persons with proliferative retinopathy should avoid weightlifting and very heavy exercises with a chance of hurting themselves (risk of intraocular...
Lean women with abnormal glucose tolerance before pregnancy had a smaller increase in fat mass (1.3 kg, P 0.04) than lean women with NGT (18). Change in fat mass was inversely associated with change in insulin sensitivity (18). There is an increase in fat mass from the prepregnant state to late pregnancy in both obese NGT and GDM women, but there was no difference between NGT and GDM women in the amount of fat accumulated (11). A wide range of fat mass and fat-free mass gain was observed (11).
Changes in bodyweight may be inversely related to change in HbA1c and directly related to the change in free insulin levels (Yki-Jarvinen et al 1992). Initially weight gain after a long period of poor glycaemic control may be associated with a reduction in basal metabolic rate and rehydration resulting from the amelioration of the osmotic diuresis associated with glycosuria (Makimattola, Nikkila and Yki-Jarvinen 1999). However, about two-thirds of subsequent long-term weight gain is associated with an increase in adipose tissue (Groop et al 1989), with the remaining weight gain due to an increase in lean muscle mass. Since excessive weight gain is undesirable for elderly patients with poor mobility, it is relevant that combination therapy of a single evening dose of intermediate acting insulin may be associated with less weight gain than a single morning injection, twice-daily injections and a multiple injection regimen (mean weight gain 1.2 kg, 2.2 kg, 1.8 kg, and 2.9 kg respectively...
Several studies have strongly suggested that enhanced oxidative stress may represent an important trigger for atherogenesis elicited by angiotensin II (Ag II). Free radical formation mediates some of the effects of hypertension. Angiotensin II concentrations are often elevated in patients with hypertension and it is a potent vasoconstrictor. It also increases smooth-muscle hypertrophy and lipoxygenase activity, which, in turn, can increase inflammation and the oxidation of LDL.
They received individual advice about how to achieve the intervention goals reduction in weight of 5 per cent or more, total fat intake less than 30 per cent of energy consumed, saturated fat intake less than 10 per cent of energy consumed, fibre intake of at least 15 g 1000kcal, and moderate exercise for 30 min per day or more. Frequent ingestion of wholemeal products, vegetables, berries and fruit, low-fat milk and meat products, soft margarines, and vegetable oils rich in monounsaturated fatty acids were recommended. The dietary advice was based on 3-day food records completed four times per year. The subjects had seven sessions with a nutritionist during the first year of the study and every 3 months thereafter. They were also individually guided to increase their level of physical activity. Endurance exercise (walking, jogging, swimming, aerobic ball games, skiing) was recommended to increase aerobic capacity and cardiorespiratory fitness....
What will help . . . Several small meals keep off body fat better than two large ones. Grazing may offset my temptations to binge. I keep more fruit in the house it's handy when appetite pangs occur. . . . Strength training twice a week builds up muscle and burns fat more than any other body tissues. I'm happy at the prospect of losing flab.
Generally, aerobic exercises, such as swimming and walking, are preferred. Resistance training, although beneficial, can be somewhat hazardous in patients with orthopedic or vascular problems, although properly designed resistance programs can be beneficial. Light weight repetitions are very effective and can be used extremely well to maintain tone.
Three prospective cohort studies have highlighted the positive impact of physical activity on preventing weight gain in adults (Haapanen et al., 1997 Coakley et al., 1998 Schmitz et al., 2000). Haapanen et al. (1997) used a clinically significant body mass gain defined as 5 kg or more over the 10-year follow-up period as a main outcome measure and leisure time physical activity was determined from self-administered questionnaires. Using logistic regression analysis they showed that the men and women with no regular weekly physical activity at the end of the follow up period had an odds ratio of 2.59 (95 per cent confidence interval (CI) 1.69-3.97) and 2.67 (1.65-4.31), respectively for clinically significant weight gain compared to the most active groups. They concluded that regular physical activity prevents body mass gain and physical inactivity is a risk factor for body mass gain and obesity among adults. Schmitz et al. (2000), reporting data from the Coronary Artery Risk...
The appeal of fad exercise programs is no less than that of fad diets. An entire exercise industry has developed that includes exercise tapes, books, workout programs, specialized centers to facilitate yoga (combat yoga, sweat yoga), strength training, weight training, jazz exercise, step aerobics, spinning, and almost every type of exercise equipment imaginable for home gyms, bedrooms, and traveling.
Cystatin C is a naturally circulating, low molecular weight, basic protein which is freely filtered by the glomerulus and almost completely reabsorbed and catabolised by tubular cells. Serum levels are independent of age, sex and lean muscle mass. Although levels reflect trends in reduced GFR, particularly
Of protein (i.e. lean meat, fowl, or liquid formula) to minimize loss of lean muscle mass during weight loss. Several studies in the past two decades have confirmed the capacity of VLCD to produce superior weight loss and maintenance (Wadden et al., 1988, 1989 Wing et al., 1994). The common features of these studies include stringent dietary intake restrictions, with or without provision of behavioural counselling, and follow up of 1-8 years (Kirschner et al., 1988 Wadden et al., 1988, 1989). Aggregate results of these investigations suggest that VLCD typically produces weight reductions of 15-25 per cent of baseline body weight with 8-16 weeks of treatment (Wadden and Osei, 2002). While this weight loss is significant in comparison to the low calorie self-selected food diets, rapid regain is common with VLCD diets and non-significant differences in weight loss are common between the two dietary approaches at even 1-year post treatment (Wadden et al., 1994 Wing et al., 1994). The...
If you have hypertension or heart disease, avoid exercises that involve pushing against an immovable object (such as a wall) or isometric exercises, where you keep your muscles contracted. Talk to your provider about exercises that are safe for you. Walking and swimming are often safe options. If you are on dialysis, you can benefit from a gradually progressing exercise program. If you've had an organ transplant, exercise can be helpful. Anti-rejection drugs often cause weight gain and muscle wasting. Try aerobic and strength training once you are given the okay and are ready. benefits your heart, lungs, and muscles. It is the best way to burn calories and get rid of fat. Stretching increases your flexibility. To see improvement, you'll need to work out at least three to four times per week. You might want to alternate days of aerobic activity with days set aside for strengthening activities for muscle toning. For more intense workouts, you might want to alternate resting days and...
In addition to exercises for cardiovascular fitness, encourage your child to lift weights. Have him select lighter weights that he can lift repetitively. This is called weight training. (He should avoid very heavy weight lifting, which is anaerobic refer to the earlier section Developing (And Sticking to) an Exercise Plan for an explanation of aerobic versus anaerobic exercise.) Weight training improves muscle strength. The exercises I recommend in this section work his upper body muscles, which are neglected with most aerobic exercises that involve only his legs. To try some other weight-training exercises, see the book Weight Training For Dummies, 3rd Edition, by Liz Neporent, Suzanne Schlossberg, and Shirley Archer (Wiley). You also can consult an exercise trainer in a fitness club to find out how to do these exercises and others safely.
Few recent studies have specifically compared different combinations of diet and exercise versus diet alone, and some recent reports surprisingly fail to support the benefits of combining strategies. Skender and colleagues (1996) reported marginal but non-significant differences in diet plus exercise versus diet alone, in a study whose conclusions were limited by attrition. Wadden et al. (1998) reported the 1-year follow-up of a clinical trial which compared four conditions including diet alone, diet plus either aerobic or strength training, or combination of all. All participants received similar diets and a 48-week group behavioural programme. At week 48, participants across all groups averaged a 15.1 kg weight loss, and no significant difference was noted between groups. Weight losses were well maintained, but no group differences were found at one-year follow-up. Wing (2002) suggests that these study results may fail to support combining strategies as each reported that...
Though a graded aerobic exercise program is usually prescribed following a myocardial infarction, there is increasing interest in the role of resistance exercise programs particularly in the elderly cardiac patient. Resistance exercise programs (typically a single set of 8-15 repetitions of 8-10 exercises, performed two to three times each week) have been emphasized in older adults to reduce age-associated reductions in muscle strength and subsequent disability. Evidence suggests that decreases in blood pressure and heart rate can be achieved with such programs (Kelley and Kelley 2000) but controversy surrounds their use after acute myocardial infarction. While many programs include some strength training (Hare et al 1995), recent American Heart Advisory guidelines found that there is insufficient research evidence to support the routine prescription of resistance training for people with moderate to high cardiac risk (Pollock et al 2000).
C-Met dominant negative mutant, and showed that HGF signal is required for development of the kidney, liver, and intestines (33). During lung development, branching tubulogenesis becomes evident in parenchymal areas at E13.5 d of the mouse embryo, and is associated with increased HGF expression in meschenchymal areas (34). When this HGF activity is neutralized by an antibody specific to HGF, branching tubulogenesis is diminished, hence HGF plays a key role for lung development (34). Furthermore, studies with the c-Met-deficient mouse strain delineated an essential role of HGF c-Met signaling in placental, hepatic, and muscular development (35-37). Given that meschenchymal stromal cells (such as fibroblasts) are a major source of HGF, HGF c-Met axis confers a mesenchyme-to-parenchyme system for organ development.
Excluding vegetable sources of protein like soybeans, legumes, nuts, and seeds, protein in your diet is usually the muscle of other animals, such as chicken, turkey, beef, or lamb. For this reason, people used to believe that you could build your own muscle by eating lots of another animals' muscle. (The truth is that you can build up your muscle only by exercising or weightlifting.) You need little protein to maintain your current level of muscle or increase it for that matter.
Growth hormone (GH) has been used for more than 40 years. GH improves height velocity in many conditions associated with impaired growth and corrects metabolic deficits attributable to GH deficiency (GHD). The approved indications for growth hormone have expanded substantially in the last several years. Now, it is also approved for the treatment of cachexia associated with acquired immunodeficiency syndrome (AIDS) (72). It is also approved as replacement therapy in the elderly with GHD. For all these purposes, the dosages are in excess of those previously recommended. These pharmacological uses have resulted in an increased incidence of glucose intolerance and DM especially among the elderly population as they are likely to be overweight, resulting in increased insulin resistance. An increased incidence of hyperglycemia has also emerged among children receiving GH in the setting of small for gestational age, Prader-Willi syndrome and Turner Syndrome (73). In addition, off-label uses...
Older adults from age 50 and above who were given only eight weeks of flexibility and resistance training had substantial improvement in strength and flexibility while their glucose levels improved as well. Weight training, which uses lighter weights, can be a form of aerobic exercise. Because the weights are light, they can be moved for prolonged periods of time. The result is improved cardiovascular fitness along with strengthening of muscles, tendons, ligaments, and bones. Weight training is an excellent way to protect and strengthen a joint that is beginning to develop some discomfort. Weight training may be good for the days that you do not do your aerobic exercise, or you can add it for a few minutes after you finish your activity. Weight training is also good for working on a particular group of muscles that you feel is weak. Very often, these muscles are in the back. Weight-training exercises can isolate and strengthen each muscle. If you do a lot of aerobic exercise that...
Puberty is a time of peak growth similar to the first year of life. The adolescent gains the last fifth of his height and 50 percent of his adult weight. Strength greatly increases, especially if he does strength-training exercises. Girls have their pubertal growth spurt earlier than boys, but boys experience a longer growth period and are taller on average at the end of growth. The percentage of body fat in boys remains about the same but significantly increases in girls, sometimes leading to the eating disorders described in Chapter 8.
Stress testing is imperative before embarking on an exercise program. Blood pressure should be controlled and guided by the response to exercise testing. Self-monitoring of blood glucose is particularly important in patients taking insulin. Although exercise does not normally aggravate diabetic neuropathy and may even reduce or delay the risk of ophthalmic complications, straining, as seen in heavy resistance training, should be avoided by those with proliferative retinopathy because of the increased risk of vitreous hemorrhage and retinal detachment. It is not known whether patients who have undergone laser procedures can tolerate more aggressive resistance activity (13).
When walking than non-obese, suggesting that this moderate intensity activity is actually more intense for the obese due to the greater relative oxygen cost of walking (78). In addition, the myriad of macrovascular and microvascular complications associated with diabetes may increase discomfort during activity and limit endurance and flexibility (71). Patients with proliferative retinopathy or hypertension, for example, should avoid resistance training and high-intensity exercises and those with peripheral neuropathy are advised to pursue activities such as swimming, where the ankle and foot are not under stress. Advice regarding appropriate footwear, foot inspection and adequate hydration should be given and those at risk of hypoglycaemia should take care to adjust insulin doses and consume sufficient carbohydrates (79). The emergence of exercise referral schemes may be an important development for the treatment of obesity in Type 2 diabetes (1).
