The Effect of Two Types of High-Intensity Interval Training on Serum Value of GH and IGF-1 in Overweight Nurses

Background: Growth hormone and insulin-like growth factor 1 are anabolic hormones that play a vital role in the growth of various physical organs. Exercise is one of the stimuli that affect GH and IGF-1 secretion. Objectives: This study aimed to compare the effect of two types of high-intensity interval training (HIIT) on plasma levels of GH and IGF-l in overweight nurses. Methods: In this study, 27 nurses were voluntarily selected and randomly assigned to three groups (9 participants for each group): 1. HIIT (type 1), including eight seconds of spring running and 12 seconds of active recovery, 2. HIIT (type 2), including a 40-meter shuttle run with maximum speed, 3. control. HIIT (type 1) was performed for four weeks, three sessions per week, each session 6 - 9 min with more than 90% HRmax. HIIT (type 2) was applied for four weeks, three sessions per week, with more than 90% HRmax. The control group did not participate in any training protocol. The serum value of GH and IGF-1 were compared in three groups. The data were analyzed by the dependent t-test and ANOVA. One-way analysis of variance (ANOVA) was used to analyze the intergroup data at P ⟨ 0.05. Results: The results showed that HIIT (type 1) and (type 2) significantly increased plasma GH (P = 0.032 in group 2 and P = 0.010 in group 1) and IGF-l (P = 0.004 in group 2 and P = 10.013 in group 1) levels in nurses. The results showed a significant difference in the variables (GH and IGF-l) among HIIT (type 1), HIIT (type 2), and control groups. Conclusions: It can be concluded that four weeks of adverse intermittent exercises are effective in increasing the concentration of GH and IGF-1 serum and decreased percentage body fat in young nurses with overweight, and proportional to the intensity of the exercise protocol response rate is different.

Objective: To study the effect of 12 weeks of high-intensity interval training (HIIT) on glycemic control in adults with type 1 diabetes with overweight or obesity. Research Design and Methods: Thirty inactive adults with type 1 diabetes who had BMI≥25kg/m2 and HbA1c≥7.5% were randomized to 12 weeks of either: HIIT exercise intervention consisting of 4x4 minutes HIIT (85-95% HRpeak) performed thrice weekly, or usual care control. In a partial cross-over design, the control group subsequently performed the 12-week HIIT intervention. The primary endpoint was the change in HbA1c from baseline to 12 weeks. Glycemic and cardiometabolic outcomes were measured at 0, 12, and 24 weeks. Results: Participants were aged 44±10 years, with diabetes duration 19±11 years, and BMI 30.1±3.1 kg/m2. HbA1c decreased from 8.63 ± 0.66% at baseline to 8.10 ± 1.04% at 12 weeks in the HIIT intervention group (p=0.01), however this change was not significantly different to the control group (HIIT -0.53 ± 0.61%, control -0.14 ± 0.48%, p=0.08). In participants who undertook at least 50% of the prescribed HIIT intervention, the HbA1c reduction was significantly greater than control (HIIT -0.64 ± 0.64% (n=9), control -0.14 ± 0.48% (n=15), p=0.04). There were no differences in insulin dose, hypoglycemia on continuous glucose monitoring, blood pressure, blood lipids, body weight or body composition between groups. Conclusions: <a>Overall, there was no significant reduction in HbA1c with a 12-week HIIT intervention in adults with type 1 diabetes. However glycaemic control may improve for people who undertake HIIT with greater adherence.</a>

Objective Liver, as one of the most important organs involved in lipids and glucose metabolism, yet no study has examined the response of liver kinase B1 (LKB1) and AMP-activated protein kinase α(AMPKα) signaling after high intensity interval training. This study aims to evaluate the effect of 16-week high intensity interval training intervention on the expression of LKB1、AMPKα in liver of aging rats. Methods 8 -month-old male Wistar rats（n=40）were randomly divided into control group (C) and HIIT group (H). Group H with 70%-90%-50%VO2max intensity training for 50min/ day, 5 days / week, lasted for 16 weeks. Rats were killed on 0, 8 and 16 weeks. We examined the protein expression of LKB1 and AMPKα in liver. Proteins were analyzed by western blot analysis. Data are mean±SD; for ANOVA, p<0.05 was significant. Results The AMPKα levels in group C and group H increased with time and there was no significant difference between the groups. The content of LKB1 in group C and group H both increased first and then decreased, but there was no significant difference between the groups. Conclusions 16-week high intensity interval training intervention had no effect on LKB1, AMPKα protein expression in aging rats.

AbstractTo describe and compare the acute heart rate changes during an incremental exercise test and high-intensity interval training (HIIT) in subjects of different glucose control. Seventy-five adults were allocated into three groups: Normoglycaemic (NG, n=32), Pre- (PreT2D, n=30) and Type 2 diabetic (T2D, n=13) subjects. Subjects performed an incremental cycling test to determine cardiorespiratory fitness (VO2max), maximum heart rate (HRmax) and HR recovery post maximal effort, as well as a HIIT cycling session. HR variations are reported as HR pre (HR-preINT), and post interval (HR-postINT), percentage of maximum HR (%HRmax), delta of HR increased (∆HRINT), and delta HR recovery after each interval (∆HRR). By groups, there was a significant difference for the %HRmax in 1st and 2nd, but not in intervals 3rd to 10th between Pre-T2D and T2D groups. There were significant differences for the %HRmax in 1st to 2nd intervals between Pre-T2D and T2D groups. Significant (P<0.05) differences at some intervals were found for ΔHRINT, and ΔHRR. These findings suggest that the HR during an incremental exercise test, and from a typical 10-intervals based HIIT protocol could be used as an intensity marker for individuals independent of their glycaemic control.

12054 Background: Patients with advanced NSCLC experience fatigue and physical deconditioning altering their quality of life. Safety and feasibility of high intensity exercise in advanced NSCLC has not been explored yet. Methods: We report the results of a single-center, prospective two-arm study. Patients with advanced NSCLC actively receiving systemic therapy or having completed treatment less than 2 months prior to enrollment were included. Patients were allocated to either an intervention arm consisting of kinesiologist supervised high intensity interval training (HIIT) at 2 sessions per week for a total of 12 weeks; or a control arm of home exercise guided by an informative pamphlet. All patients were evaluated at baseline, 6 and 12 weeks by a kinesiologist. Quality of life (QoL) exercise surveys and measurement of strength were measured. Results: Sixty patients were enrolled between January 2018 and March 2020. The study was interrupted due to COVID-19. Thirty-two patients were included in the exercise program and 28 patients in the control group. Both groups were balanced in respect to baseline characteristics. A total of 32 (53%) patients went off protocol, 13 (18%) patients stopped due to symptomatic disease progression which included 2 (3%) deaths, 2 (3%) stopped due to COVID-19 preoccupations and the remaining patients withdrew for other reasons. 42 (70%) patients were evaluated at 6-weeks and 28 (47%) completed the 12-week follow-up, with equal distribution in each group. There were no significant difference at 12 weeks in the physical assessment nor the overall QoL scores between both groups: FACT-L on 135 points (+4.1 vs +1.7, p = 0.342) and FACIT on 52 points (+3 vs -0.2, p = 0.832). Patients in the exercise group demonstrated a significant improvement at 12 weeks in the Lung Cancer Symptoms domain on 28 points (22.3 vs 19.8, p = 0.015) as well as the Physical Wellbeing domain on 28 points (23.6 vs 20.6, p = 0.056) compared to the control group, respectively. No significant exercise related complications were reported. After the study, 9 of the 14 patients (64%) who completed the HIIT program continued to exercise virtually with a kinesiologist in contrast to none in the control group. Conclusions: This study demonstrated the safety and potential benefit of a HIIT program on lung-specific and physical wellbeing in patients with advanced NSCLC on active treatment. This study provides further support on the role of supervised physical exercise in patients living with cancer. Clinical trial information: 16.229.
