High intensity interval training (HIIT) using elastic bands is easy to do, but no data on its impact on glycemic control in people with type 1 diabetes (T1D) are available. Six males with T1D performed three weekly sessions of HIIT using elastic bands for 12 weeks. Each session consisted of eight exercises. Glycemic control was evaluated by using intermittent scanning continuous glucose monitoring two weeks before study onset (baseline) and during the intervention period in the first two (first stage) and last two weeks (last stage). In the 24 h post-exercise, time-in-range (70–180 mg/dL) was reduced from baseline to the end of the study (67.2% to 63.0%), and time-above-range (>180 mg/dL) seemed to increase from baseline across the study (20.8% → 27.5% → 22.1%, from baseline → first → last stage), but did not show any statistical significance. Time in hypoglycemia (either < 70 mg/dL or <54 mg/dL) did not show statistically significant differences. This study shows that a HIIT program with elastic bands is safe and effective to perform in T1D patients, keeping blood glucose levels in a safe range.

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: The aim of this study was to assess the benefit of using high-intensity interval training for cardiovascular patients undergoing outpatient rehabilitation in a standard short-term (three-week) program in Germany. Design: This is a randomized controlled trial (RCT). Setting: This study was conducted at Cardiowell (Wuppertal, Germany), an outpatient rehabilitation center. Intervention: Patients underwent the typical three-week German outpatient rehabilitation program using either moderate continuous training (i.e. the standard training program) or high-intensity interval training. Main measures: A total of 50 patients of an outpatient rehabilitation center were randomized into two groups. The control group underwent the standard rehabilitation protocol that applied moderate continuous training, and the intervention group trained according to a high-intensity interval protocol. Patients trained on a bicycle ergometer. Peak power output, oxygen uptake parameters, heart frequencies, and blood pressure were compared at the beginning and at the end of the rehabilitation program. Results: After three weeks, the intervention group had improved to a significantly greater extent in maximal performance parameters than the control group: the peak power output (20.9 (±14.1) W; control 8.8 (±10.4) W), maximum oxygen uptake (0.33 (±0.33) L/min; control 0.05 (±0.29) L/min)), relative maximum oxygen uptake (3.4 (±4.2) mL/kg/min; control 0.9 (±3.1) mL/kg/min), and O2 pulse (1.8 (±2.2) mL/heart beat; control 0.35 (±1.7) mL/heart beat). Conclusion: The implementation of high-intensity interval training during a typical three-week German cardiac rehabilitation has the power to increase the outcome for the patients.
