Adequate protein intake and resistance training are effective strategies to maintain muscle mass, but the effect of their combination on metabolic profile during weight loss remains to be determined in older adults. The main objective of this study was to determine the effect of a 16-week high-protein caloric restriction combined with resistance training on chronic disease risk factors in obese older individuals with metabolic impairments. A total of 26 overweight adults aged between 60 and 75 years (BMI 32.4 ± 3.9 kg/m2) with at least 2 factors of the metabolic syndrome participated in this study and were randomized into two groups: 1) high-protein caloric restriction (HP; n= 12) and 2) high-protein caloric restriction combined with dynamic-resistance training (HP+RT; n=14). Caloric intake was reduced by 500 kcal/d in all participants and protein intake equated 25-30% of total calories (~1.4 g/kg/d). Exercise training consisted of 3 session/week of resistance training on pulley machines. Outcome measures included total and trunk fat mass (FM), total and appendicular lean body mass (LBM), fasting glucose level, lipid profile and blood pressure. Our results showed that total and trunk FM (all p<0.0001) as well as fasting glucose (p<0.0001), triglycerides (p=0.002) and total cholesterol (p=0.03) levels decreased similarly in both groups. However, total (p=0.04) and appendicular (p=0.02) LBM decreased in the HP group only. Our data show that high-protein energy restriction improves health profile of obese elderly at high risk of chronic disease but needs to be combined with resistance training to maintain LBM.
Objectives: To compare the effect of low-volume high-intensity interval training (HIIT) with moderate-intensity continuous training (MICT) on fat mass, cardiometabolic profile, and physical capacity, and confirm its feasibility in older women. Methods: Inactive older women (60–75 years) were randomly assigned to 8 weeks of either HIIT (75 min/week; n = 9) or MICT (150 min/week; n = 9). Body composition, fasting metabolic profile, cardiovascular risk (Framingham score), and physical capacity (senior fitness test, peak oxygen uptake) were assessed before and after the intervention. Feasibility was evaluated with completion rate (training compliance; dropout rate) and affective response (Feeling Scale; pre- and postexercise). Results: Total cholesterol level, non-high-density lipoprotein cholesterol level, and the Framingham risk score decreased in both groups (ps ≤ .03). Although peak oxygen uptake remained unchanged, the 6-min walk test distance increased (p < .0001), irrespective of the group. Completion rate and affective responses were not different between groups (ps ≥ .38). Conclusion: A short-term HIIT program is feasible and provides as much benefits as MICT in older women.
that included demographics, chronic conditions, rural location, prior hospitalizations, and high vs. low hurricane impact revealed that post-hurricane change in personal care services was associated with hospital admissions in the three months after the hurricane. Compared to no change in personal care services, decrease in personal care services was associated with increased incidence of hospital admissions (IR = 0.549; 95%CI=0.435,0.663;p<0.001), whereas increase in personal care services was associated with decreased incidence of hospitalization (IR=-0.61; 95%CI=-0.714,-0.508;p<0.001). Disaster-related reduction in PCS increases vulnerable older adults' risk for hospital admissions. Methods Participants included 20 patients with MCI and their respective care partners who were actively deciding whether to pursue AI. All participants underwent pre-testing counseling (PTC) including: overviews of MCI, AD, and AI, potential pros/cons of AI, and implications for AD risk. Following PTC, participants were encouraged to carefully consider whether to pursue AI. Within 2 weeks of PTC, qualitative interviews were conducted using a semi-structured interview guide with openended questions about the decision making process, including which factors were considered during the decision. Interview transcripts were coded and categorized using content analysis. HOW DO PATIENTS WITH MILD COGNITIVEResults Patients and care partners consistently reported the potential to gain more information about the underlying cause, or likely course, of their MCI as a major motivator for pursuing AI. Many were actively anticipating their emotional and behavioral reactions to AI results. Upon probing, most acknowledged the limitations and potential drawbacks of AI (e.g., "They aren't going to find something on the scan and give me a pill and I'll be better."). Yet, there were 11 instances of misunderstanding or overstating the potential value of AI (e.g., "It will tell me how far along I am.").Conclusion Even with PTC, some individuals may disproportionately emphasize potential benefits when considering AI. The impact of high-intensity interval training (HIIT) compared to the current exercise recommendations (moderate intensity continuous aerobic exercise; CONT) has to be verified in obese older women before being used by health professionals. Objective: The purpose of this study is to compare the effect of HIIT to CONT on body composition, metabolic profile and affective responses in obese elderly. Methods: A total of 20 older and sedentary women (60-75 years) with abdominal obesity (waist circumference ≥ 88 cm) are currently recruited and randomized to one of the following group: 1) HIIT (n=10); 2) CONT (n=10). All variables are measured before and after 8 weeks of intervention: Anthropometry (weight, height, body mass index), body composition (fat mass [FM], lean body mass [LBM], visceral adipose tissue [VAT]; DXA), metabolic profile (fasting lipid profile, glucose and insulin) and physical capacity (senior fitness test). Affective responses ...
