This study utilized a randomized control trial to examine whether structural changes in the precuneus, insula, caudate, hippocampus, and putamen were related to exercise. A total of 197 healthy older adults with no evidence of dementia participated in moderate-intensity interval training or low-intensity continuous training for 16 weeks. Size decreased in the right hippocampus such that the effect of time was significant but the interaction with condition was not. For the left hippocampus, size decreased in the low-intensity continuous training condition but increased in the moderate-intensity continuous training plus interval training condition at the trend level. Finally, there was a significant time-by-condition interaction such that the thickness of the left insula increased for low-intensity continuous training and decreased for moderate-intensity continuous training plus interval training. Few structural changes were associated with the exercise intervention. Future studies should examine the effects of exercise on brain structure in high-risk or clinical populations for a longer period of time.

Abstract Aerobic exercise is a universally recommended strategy for increasing healthspan, and recent advances in next-generation sequencing and bioinformatics (e.g., RNA-seq/transcriptomics) have made it possible to broadly profile the molecular transducers of exercise. However, most transcriptome studies of exercise have focused on coding genes only, and the transcriptomic response to different exercise interventions has not been characterized by RNA-seq in older adults. Therefore, we performed total RNA-seq (to capture both coding and non-coding gene expression) on peripheral blood mononuclear cells collected from healthy, previously sedentary older adults (males and females, aged 70 ± 1 years). Samples were collected before and after 16 weeks of either low-intensity continuous training (LICT, 50% maximum heart rate, 3 x 30 min/week) or moderate-intensity continuous training plus interval training (MICT+IT, 60-80% maximum heart rate, progressively increased to include IT, 3 x 30 min/week). We found that both interventions modified biological processes (transcriptome modules) related to oxygen transport and reduced inflammatory signaling/immune activation processes (more pronounced with LICT). Interestingly, transcriptome changes unique to LICT subjects included increased expression of genes linked with vascularization and endothelial cell migration, whereas MICT+IT was uniquely associated with a robust increase in antioxidant response gene expression. We also observed numerous changes in long non-coding RNAs and microRNAs that could be linked with these exercise-associated gene expression changes with both interventions. These data provide a first comprehensive look into transcriptomic changes associated with moderate vs. low intensity aerobic exercise in older adults, and they suggest distinct benefits of each exercise strategy.

Highlight:Aerobic exercise was reduced body fat and increased free fatty acids.LICT and MICT decreased body fat and increased free fatty acids. Abstract:Overweight is fat imbalances can affect the health. It is one of the problems in many countries, especially Indonesia recorded an increase case in 2007 (8.8%) to 2013 (13.5%). Overweight categorized by 25-30 kg/m2 body mass index in units (Organization  2018). Figures overweight can be pressed to provide some treatments, such as aerobics sports activities. This study aimed to determine the effect of Continuous Low Intensity Training (LICT) and Moderate Intensity Continuous Training (MICT) to decrease body fat content (FM) and increase in free fatty acids (FFA) in overweight women. 18 female subjects completed the study 4X/week exercise LICT or MICT for 5 weeks. LICT and MICT performed for 30 minutes with an additional 5 minutes warm-up and 5 minutes of cooling down with LICT intensity of 60%-70% and MICT 70%-80% of maximum HR where both types of exercise using ergo cycle while measurement FM and FFA were measured before and after practice. LICT occurred decreasing in body fat and increasing in free fatty acids that significant pre and post LICT (p < 0.05). MICT occurred decreasing in body fat and increasing in free fatty acids that significant pre and post MICT (p<0.05). In the second comparison group (LICT and MICT) were decline against body fat and an increased in free fatty acids between workouts Low-Intensity Continuous Training (LICT) greater tendency than Moderate-Intensity Continuous Training (MICT) with delta FM (p = 0.120) and delta FFA (p=0.131) in which the value is >0.05. LICT and MICT was increase while body fat was decreased. The results of a comparison test occur list downward trend in body fat while in free fatty acids was increased.

Abstract Most older adults do not exercise regularly. Among those who do, the majority only perform one type of exercise, and— as such— are either not getting the benefits of endurance exercise or resistance exercise. The aim of this pilot study was to determine which standalone exercise strategy has the greatest effect on both cardiorespiratory and lower-extremity muscular function in insufficiently active older adults 60 to 75 years of age (N = 14). Participants were randomly assigned to either resistance training (RT, n=5), moderate intensity continuous training on a stationary bicycle (MICT, n=4), or high-intensity interval training on a stationary bicycle (HIIT, n=5) for supervised exercise sessions three times per week for 12 weeks. Maximal oxygen consumption increased a comparable amount in all groups (11.9±11.2% for HIIT vs. 8.0±14.8% for MICT vs 9.8±5.7% for RT). Leg extensor power did not change in the HIIT group (-0.34±5.2%), but increased by 5.2±9.7% in the MICT group and 14.5±26.1% in the RT group. Leg extensor strength decreased by 1.7±22.1% in the HIIT group and 0.6±6.4% in the MICT group, but increased by 27.3±21.2% in the RT group. These findings demonstrate that RT results in improved lower-extremity strength and power, as well as improvements in maximal aerobic capacity comparable to MICT and HIIT in older adults. Thus, RT should be promoted as an essential exercise strategy for older adults, particularly for individuals who are inactive or that are only performing one type of exercise regularly.

Objective: To compare the acute and chronic effects of low-volume high-intensity interval training (HIIT) to moderate-intensity continuous training (MICT) on glycemic control, body composition and continuous glucose monitoring (CGM) in older women with type 2 diabetes (T2D). Methods: Thirty older women (68 ± 5 years) with T2D were randomized in two groups—HIIT (75 min/week) or MICT (150 min/week). Glucose homeostasis (A1c, glucose, insulin, HOMA-IR2) and body composition (iDXA) were measured before and after the 12-week exercise intervention. During the first and last week of training (24-h before and 48-h after exercise), the following CGM-derived data were measured: 24-h and peak glucose levels, glucose variability and time spent in hypoglycemia as well as severe and mild hyperglycemia. Results: While lean body mass increased (p = 0.035), total and trunk fat mass decreased (p ≤ 0.007), without any difference between groups (p ≥ 0.81). Fasting glucose levels (p = 0.001) and A1c (p = 0.014) significantly improved in MICT only, with a significant difference between groups for fasting glucose (p = 0.02). Neither HIIT nor MICT impacted CGM-derived data at week 1 (p ≥ 0.25). However, 24-h and peak glucose levels, as well as time spent in mild hyperglycemia, decreased in HIIT at week 12 (p ≤ 0.03). Conclusion: These results suggest that 12 weeks of low-volume HIIT is enough to provide similar benefit to MICT for body composition and improve the acute effect of exercise when measured with CGM.

AbstractLipid goal achievement and statin consumption were estimated at extreme/very-high/high/moderate and low cardiovascular risk categories. In the cross-sectional study, 585 patients treated with statin therapy referring to the heart clinic of Birjand were recruited. Patients were classified and examined LDL-C values and the proportion reaching targets according to the American Association of Clinical Endocrinologists guideline. Three patterns of statin use (high/moderate/low-intensity statin therapy) in all patients were examined and attainments of LDL-C goal in cardiovascular risk groups have been demonstrated. Over half the populations (57.6%) were in the very-high CVD risk group. The results showed that the proportion of patients meeting total LDL-C goal values according to the guidelines was 43.4%. The frequency of patient had achievement LDL goal lower in high-intensity pattern (N = 13, 2.3%), compared with moderate (N = 496, 86.1%) and low-intensity patterns (N = 67, 11.6%). In general, LDL-C goal achievement was greatest with moderate-intensity statin use. LDL-C reduction after statin consumption was estimated about one-third of the studied population. It seems likely that the achievement of a therapeutic target for serum lipids such as LDL-C improved is far more cost-effective and would be able to reach the target LDL as well changing the type and intensity of statins.
