METHODS: Participants were randomized to a training group that performed 18 sessions over six weeks (n=9), or a non-training control group (n=10). Each session involved a 1-minute warm-up (jumping jacks), followed by 1-minute bouts of five exercises (burpees, high knees, split squat jumps, high knees, squat jumps), each interspersed with 1-minute of active recovery (walking around the room). Participants were instructed to complete as many repetitions per bout as possible, at a self-determined ―challenging‖ pace. All sessions were supervised and compliance was 100%. RESULTS: Mean intensity during training was 82±5% of maximal heart rate. Borg Scale ratings of perceived exertion for the five exercises ranged from 12±2 to 15±3 out of 20. ANCOVA revealed a significant difference between groups after the intervention, such that VO2peak was higher in the training group compared to control (34.2±6.4 vs 30.3±11.1 ml/kg/min; P=0.03). Peak power output during the VO2peak test was also higher after training compared to control (211±43 vs 191±50 W, p=0.004). There were no changes in leg muscular endurance, handgrip strength or vertical jump height in either group. CONCLUSIONS: A simple bodyweight interval training program, requiring 11 minutes per session, increased cardiorespiratory fitness in previously sedentary young adults when performed three times per week for six weeks.

METHODS: Thirty six obese elderly women with T2DM patients (76.64 ± 6.56 years, %BF 36.09 ± 4.18, HbA1c 7.05 ± 0.85%) were randomly assigned to the combined exercise group (n = 20) and to the control group (n = 16). The 60 minute combined exercise program (outdoor walking + elastic-band resistance exercise) was performed 3 times per week for 12 weeks, and the intensity was progressively increased every four weeks (Outdoor walking RPE 11-14; Band exercise 1-4 weeks: OMNI-RES 3 to 4, 5-8 weeks: OMNI-RES 5 to 6, 9-12weeks: OMNI-RES 7 to 8). RESULTS: There were significant time × group interactions for irisin (p<0.001), C-peptide (p=0.002), HOMA-β (p<0.001), HOMA-IR (p=0.045), fasting blood glucose (p<0.001), and HbA1c (p<0.001). Result of combined exercise group were as follows; percentage of body fat had significantly decreased, and irisin level had significantly increased. In addition, HbA1c and Glucose were significantly decreased to improve glycemic control, and C-peptide, CPI and HOMA-β levels were significantly increased. Fasting glucose (r=-0.424), HbA1c (r=-0.351), SBP (r=-0.397) and percentage of body fat (r=-0.423) changes level showed a negative whereas HOMA-β (r=0.411) and aerobic endurance (r=0.355) changes level had a positive correlation with irisin change level. CONCLUSIONS: Combined exercise improves irisin levels and regulates percentage of body fat and blood glucose, which improves beta-cell function than non-exercise. Therefore, progressive combined exercise improves body composition, blood glucose and β-cell function by increasing irisin levels in obese elderly women with type 2 diabetes.","PeriodicalId":14781,"journal":{"name":"Journal is not defined within the JOURNAL database.","volume":"71 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79880313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, whether combined exercise modulates novel metabolic hormones and alarmins is unknown. FGF-21 was reported to modulate glucose metabolism in physically active adults, while IL-33, a recently discovered alarmin, is prognostic for breast cancer outcomes. This study aimed to determine the effects of 3 months of combined aerobic and strength exercise on systemic FGF-21, FGF-23, IL-33 and cytokines in Asian breast cancer patients. METHODS: Patients with early stage (I-II) breast cancer underwent curative breast surgery and were randomized into a combined aerobic and strength exercise group (Age: 55.3 ± 9.2 years; BMI: 26.7 ± 3.8; N = 23) or observation group (Age: 49.3 ± 8.7 years ; BMI: 24.7 ± 4.6; N = 20) that spanned 3 months. Antecubital blood was collected at baseline, 3 months and 6 months. Serum concentration of cytokines (IL-10, IL-12, IL-33, IFN-γ, TNF-α) and myokines (FGF-21, FGF-23) were quantified using a customized magnetic bead panel (Milliplex®) and read with a Luminx 200TM instrument. Biomarker data were assessed by a 2-way [group (exercise vs. observation) by time (baseline, 3 months, 6 months)] analysis of variance (ANOVA). Data are reported as means ± SD, with significance set at P < 0.05. RESULTS: A significant main effect of intervention was observed for FGF-21 (P < 0.01), with patients in the exercise group presenting with higher FGF-21 at 3 months (73.16 ± 54.05 pg/mL vs. 46.47 ± 25.33 pg/mL) and 6 months (66.67 ± 50.03 pg/mL vs. 41.79 ±33.81 pg/mL), compared with the observation group. A significant main effect of exercise on IFN-γ (P < 0.05) was observed, with lower serum IFN-γ in the exercise group at 3 months (3.85 ± 4.34 pg/mL vs. 5.43 ± 7.28 pg/mL and 6 months (3.89 ± 4.58 pg/mL vs. 5.32 ± 8.1 pg/mL), compared with controls. No significant differences were observed between groups in other outcome measures. CONCLUSIONS: A 3-month aerobic and strength exercise program preserves serum FGF-21, possibly associated with better glucose control in breast cancer patients. Lower serum IFN-γ after exercise training may suggest an attenuated pro-inflammatory response, which may be linked to better immune outcomes.","PeriodicalId":14781,"journal":{"name":"Journal is not defined within the JOURNAL database.","volume":"117 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79943757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
