Abstract
Abstract Aim To compare the efficacy of 10‐20‐30 training versus moderate‐intensity continuous training (MICT) on HbA1c, body composition and maximum oxygen uptake (V˙O 2 max) in male patients with type 2 diabetes (T2D). Materials and Methods Fifty‐one male participants with T2D were randomly assigned (1:1) to a 10‐20‐30 (N = 26) and a MICT (N = 25) training group. Interventions consisted of supervised cycling three times weekly for 10 weeks, lasting 29 minutes (10‐20‐30) and 50 minutes (MICT) in a local non‐clinical setting. The primary outcome was change in HbA1c from baseline to 10‐week follow‐up. Results Of 51 participants enrolled, 44 (mean age 61.0 ± 6.8 [mean ± SD] years, diagnosed 7.5 ± 5.8 years, baseline HbA1c 7.4% ± 1.3%) were included in the analysis. Training compliance was 84% and 86% in 10‐20‐30 and MICT, respectively. No adverse events occurred during the intervention. HbA1c decreased ( P <0.001) by 0.5 (95% CI −0.72 to −0.21) percentage points with training in 10‐20‐30, with no change in MICT. The change in 10‐20‐30 was greater ( P <0.05) than in MICT. Visceral fat mass decreased ( P <0.05) only with 10‐20‐30 training, whereas total fat mass decreased ( P <0.01) and V˙O 2 max increased ( P <0.01) with training in both groups. Conclusions Ten weeks of 10‐20‐30 training was superior to MICT in lowering HbA1c, and only 10‐20‐30 training decreased visceral fat mass in patients with T2D. Furthermore, 10‐20‐30 training was as effective as MICT in reducing total fat mass and increasing V˙O 2 max, despite a 42% lower training time commitment.
