Osteoporosis (low bone strength) and sarcopenia (low muscle mass, strength and/or impaired function) often co-exist (hence the term 'sarco-osteoporosis') and have similar health consequences with regard to disability, falls, frailty and fractures. Exercise and adequate nutrition, particularly with regard to vitamin D, calcium and protein, are key lifestyle approaches that can simultaneously optimize bone, muscle and functional outcomes in older people, if they are individually tailored and appropriately prescribed in terms of the type and dose...

BACKGROUND: The effect of an exercise program on the body composition, muscular strength (MS), biochemical markers, and bone mineral density (BMD) of individuals undergoing gastric bypass is unclear. We assessed lean mass (LM), MS, bone remodeling markers, and BMD before and after supervised weight-bearing and aerobic exercise training in obese patients who underwent Roux-en-Y gastric bypass (RYGB). METHODS: This study included 37 obese patients (81.1% women, mean age 38...

BACKGROUND: The ketogenic diet (KD) is a very low-carbohydrate, high-fat and adequate-protein diet that without limiting calories induces different metabolic adaptations, eg, increased levels of circulating ketone bodies and a shift to lipid metabolism. Our objective was to assess the impact of a 6-week non-energy-restricted KD in healthy adults beyond cohorts of athletes on physical performance, body composition, and blood parameters. METHODS: Our single arm, before-and-after comparison study consisted of a 6-week KD with a previous preparation period including detailed instructions during classes and individual counselling by a dietitian...

BACKGROUND: Movement asymmetries during walking are common after anterior cruciate ligament (ACL) injury and reconstruction and may influence the early development of posttraumatic osteoarthritis. Preoperative neuromuscular training (like perturbation training, which is neuromuscular training requiring selective muscle activation in response to surface perturbations) improves gait asymmetries and functional outcomes among people who are ACL-deficient, but the effect of postoperative perturbation training on gait mechanics after ACL reconstruction is unknown...

BACKGROUND: Among older, overweight, and obese adults with either cardiovascular disease or the metabolic syndrome, reduced mobility and loss of leg strength are important risk factors for morbidity, disability, and mortality. It is unclear whether community-based approaches to weight loss may be an effective solution to this public health challenge. METHODS: An 18-month three-site, randomized controlled trial conducted by YMCA staff, with blinded assessors, enrolled 249 older, overweight, and obese adults with either cardiovascular disease or metabolic syndrome with randomization to three interventions: weight loss alone (WL), weight loss + aerobic training (WL + AT), and weight loss + resistance training (WT + RT)...

BACKGROUND: Traumatic transtibial amputations lead to an early decline in the use and weight bearing of the residual limb. These changes result in progressive quadriceps muscle atrophy with strength loss that affects standing and walking. Neuromuscular electrical stimulation (NMES) may be useful as an adjunct to amputee prosthetic rehabilitation to maintain quadriceps muscle strength and mass. The objective of this pilot study was to compare the effects of a home-based NMES rehabilitation program plus the traditional military amputee rehabilitation program (TMARP) to the effects of TMARP alone on quadriceps muscle strength, functional mobility, and pain in military service members after a combat-related lower extremity amputation...

PURPOSE: Quadriceps muscle weakness is a serious complication of physical inactivity following hospitalization due to acute exacerbations of chronic obstructive pulmonary disease (AECOPD). Preventing strength loss during AECOPD is therefore a high priority. We aimed to evaluate the feasibility of progressive knee-extension resistance training, using ankle weight cuffs on patients with AECOPD, based on prespecified criteria for feasibility. METHODS: Thirty-four patients (18 men, mean age 74 years, forced expiratory volume in 1 second = 33% predicted) with AECOPD participated in daily knee-extension strength training...

Hypoenergetic diets and resistance training (RT) have been suggested to be important components of weight loss strategy programs; however, there is little evidence as to the chronic effects of different macronutrient compositions on strength performance and muscle mass with RT. The purpose of this study was to compare the effects of carbohydrate restrictive (CRD) and conventional (CONV) diets combined with RT on strength performance and muscle thicknesses in overweight and obese participants already involved in RT programs...

RATIONALE: Clinical control is difficult to achieve in obese patients with asthma. Bariatric surgery has been recommended for weight loss and to improve asthma control; however, the benefits of nonsurgical interventions have been poorly investigated. OBJECTIVES: To examine the effect of exercise training in a weight-loss program on asthma control, quality of life, inflammatory biomarkers, and lung function. METHODS: Fifty-five obese patients with asthma were randomly assigned to either a weight-loss program plus exercise (WL + E group, n = 28) or a weight-loss program plus sham (WL + S group, n = 27), where the weight-loss program included nutrition (caloric restriction) and psychological therapies...

BACKGROUND: Intermittent fasting (IF) is an increasingly popular dietary approach used for weight loss and overall health. While there is an increasing body of evidence demonstrating beneficial effects of IF on blood lipids and other health outcomes in the overweight and obese, limited data are available about the effect of IF in athletes. Thus, the present study sought to investigate the effects of a modified IF protocol (i.e. time-restricted feeding) during resistance training in healthy resistance-trained males...

BACKGROUND: The presence of frailty or prefrailty in older adults is a risk factor for postsurgical complications. The frailty phenotype can be improved through long-term resistance and aerobic training. It is unknown whether short-term preoperative interventions targeting frailty will help to mitigate surgical risk. The purpose of this study was to determine the proportion of frail and prefrail patients presenting to a thoracic surgical clinic who could benefit from a frailty reduction intervention...

The incidence of type 2 diabetes is increasing in Australia's older adult population. Sarcopenia, the age-related decline in skeletal muscle mass, quality and function, may make a significant but under-appreciated contribution to increasing the risk of type 2 diabetes. As skeletal muscle is the largest insulin-sensitive tissue in the body, low muscle mass in sarcopenia likely results in reduced capacity for glucose disposal. Age-related declines in muscle quality, including increased mitochondrial dysfunction and fat infiltration, are also implicated in skeletal muscle inflammation and subsequent insulin resistance...

OBJECTIVE: Obesity, being a world epidemic, is responsible for an increased risk of mortality and various comorbidities. The loss of weight, particularly of body fat, would lower this risk. This is why we have developed an aerobic, resistance and interval training program over a 6-week period whose main goal is to reduce body fat by 5%. MATERIAL/PATIENTS AND METHODS: We have assessed the evolution of body fat by bioelectrical impedance analysis, of [Formula: see text] by a cardiac stress test on a cycle ergometer, of leg muscular strength, of quality of life by the SF-36 health survey, in 20 sedentary, moderately to severely obese patients between the age of 18 and 70years old, before and after a 6-week training program mixing aerobic, resistance and interval training exercises for 45minutes, twice daily and 5days per week, with a food rebalancing with normocaloric diet...

BACKGROUND: Optimizing body composition for healthy aging in the community is a significant challenge. There are a number of potential interventions available for older people to support both weight gain (for those who are underweight) and weight loss (for overweight or obese people). While the benefits of weight gain for underweight people are generally clearly defined, the value of weight loss in overweight or obese people is less clear, particularly for older people. OBJECTIVES: This umbrella review aimed to measure the effectiveness of nutritional interventions for optimizing healthy body composition in older adults living in the community and to explore theirqualitative perceptions...

BACKGROUND: Bed rest studies have shown that high load (HL) resistance training can mitigate the loss of muscle size and strength during musculoskeletal unloading; however, not all individuals are able to perform HL resistance exercise. Blood flow restricted (BFR) resistance exercise may be a novel way to prevent maladaptation to unloading without requiring HL exercise equipment. This study evaluated the muscular training adaptations to HL and BFR resistance training during unilateral lower limb suspension (ULLS), a human limb unloading model...

Wireless sensor networks (WSNs) have become more and more diversified and are today able to also support high data rate applications, such as multimedia. In this case, per-packet channel handshaking/switching may result in inducing additional overheads, such as energy consumption, delays and, therefore, data loss. One of the solutions is to perform stream-based channel allocation where channel handshaking is performed once before transmitting the whole data stream. Deciding stream-based channel allocation is more critical in case of multichannel WSNs where channels of different quality/stability are available and the wish for high performance requires sensor nodes to switch to the best among the available channels...

PURPOSE: This study examined the effects of a five-week intervention combining vigorous interval training (VIT) with diet among twenty-four obese adolescents. Fourteen girls and ten boys (aged 14 to 15) schooled in a pediatric rehabilitation center participated. PURPOSE: The VIT intensity was targeted and remained above 80% of maximal heart rate (HR) and over six kilocalories per minute. Pre- and post-intervention measures were body composition (BMI, weight, body fat percentage), physical self-perceptions (PSP), physical fitness (six-minute walking distance and work) and its associated physiological responses (HRpeak and blood lactate concentration)...

BACKGROUND: In the United States, over 34 million American post-menopausal women have low bone mass (osteopenia) which increases their risk of osteoporosis and fractures. Calcium, vitamin D and exercise are recommended for prevention of osteoporosis, and bisphosphonates (BPs) are prescribed in women with osteoporosis. BPs may also be prescribed for women with low bone mass, but are more controversial due to the potential for adverse effects with long-term use. A bone loading exercise program (high-impact weight bearing and resistance training) promotes bone strength by preserving bone mineral density (BMD), improving bone structure, and by promoting bone formation at sites of mechanical stress...
