Low-intensity resistance training improves muscle strength, glycaemic function in elderly diabetics

10 Sep 2018

Low-intensity resistance training is effective at improving muscle size and strength and glycaemic function in elderly type 2 diabetes patients, a recent study has found.

Nine type 2 diabetes patients (mean age 68.2±9.7 years; 5 males) were recruited and underwent low-intensity resistance training two times a week for 16 weeks. Study outcomes included body weight, fat mass, lean body mass, knee extension and flexion strengths, and changes in fasting HbA1c levels. Wilcoxon signed-rank tests were used to evaluate the changes in outcome variables over time.

The low-intensity resistance training programme demonstrated a significant effect on several measures of body composition. For instance, mean body weight dropped significantly from 65.0±8.7 to 64.1±8.4 kg following the intervention (p=0.0499).

Similarly, significant 16-week reductions were observed for body fat mass (21.2±5.0 to 20.2±5.0 kg; p=0.012) and body fat percentage (32.8±6.8 percent to 31.5±6.6 percent; p=0.012), while significant increases were recorded for total lean body mass (63.6±6.6 percent to 64.7±6.5 percent; p=0.012) and lean body mass of the trunk (30.3±3.5 percent to 31.4±4.1 percent; p=0.017).

Significant improvements in muscle strength were also observed, both for isokinetic knee extension (angular velocity: 60o/s: 72.9±32.1 to 80.4±28.4 N·m; p=0.015; 180o/s: 46.3±17.7 to 52.7±19.6 N·m; p=0.021) and flexion (angular velocity: 60o/s: 42.7±20.7 to 50.9±20.2 N·m; p=0.012; 180o/s: 25.3±12.4 to 36.2±12.3 N·m; p=0.008).

The same was true for maximum leg press strength (62.4±19.9 to 101.2±22.7; p=0.008). In contrast, the 16-week exercise regimen had no significant effect on HbA1c (7.1±0.5 percent to 6.8±0.4 percent; p=0.066) and fasting plasma glucose (124.8±16.5 to 129.6±31.2 mg/dL; p=0.767).
