Abstract

OBJECTIVE—To examine whether improvements in glycemic control and body composition resulting from 6 months of supervised high-intensity progressive resistance training could be maintained after an additional 6 months of home-based resistance training. RESEARCH DESIGN AND METHODS—We performed a 12-month randomized controlled trial in 36 sedentary, overweight men and women with type 2 diabetes (aged 60–80 years) who were randomly assigned to moderate weight loss plus high-intensity progressive resistance training (RT&WL group) or moderate weight loss plus a control program (WL group). Supervised gymnasium-based training for 6 months was followed by an additional 6 months of home-based training. Glycemic control (HbA1c), body composition, muscle strength, and metabolic syndrome abnormalities were assessed at 0, 3, 6, 9, and 12 months. RESULTS—Compared with the WL group, HbA1c decreased significantly more in the RT&WL group (−0.8%) during 6 months of supervised gymnasium-based training; however, this effect was not maintained after an additional 6 months of home-based training. In contrast, the greater increase in lean body mass (LBM) observed in the RT&WL group compared with the WL group (0.9 kg, P < 0.05) after the gymnasium-based training tended to be maintained after the home-based training (0.8 kg, P = 0.08). Similarly, the gymnasium-based increases in upper body and lower body muscle strength in the RT&WL group were maintained over the 12 months (P < 0.001). There were no between-group differences for changes in body weight, fat mass, fasting glucose, or insulin at 6 or 12 months. CONCLUSIONS—In older adults with type 2 diabetes, home-based progressive resistance training was effective for maintaining the gymnasium-based improvements in muscle strength and LBM but not glycemic control. Reductions in adherence and exercise training volume and intensity seem to impede the effectiveness of home-based training for maintaining improved glycemic control.

  • Resistance machines and free weights can result in fairly equivalent gains in strength and mass of targeted muscles.

    “Resistance machines and free weights (e.g., dumbbells and barbells) can result in fairly equivalent gains in strength and mass of targeted muscles”

    From Exercise and Type 2 Diabetes (2010) · cites this paper as [66]

    The Intervention and Anthropometric and body composition measures sections describe machine-based training followed by free-weight training: strength and lean body mass improved during the machine-based phase, and those improvements were largely maintained during the free-weight phase. The paper says the home-based phase produced no further strength gains and that its sequential design does not permit a direct comparison, so it does not establish fairly equivalent gains from the two types of equipment.

  • CR intervention in elderly humans results in a reduction or maintenance of muscle strength.

    “CR intervention in elderly humans results in a reduction [18,19] or maintenance [15,16,20,24] of muscle strength.”

    From Resistance Training Prevents Muscle Loss Induced by Caloric Restriction in Obese Elderly Individuals: A Systematic Review and Meta-Analysis (2018) · cites this paper as [24]

    The Abstract (page unavailable) reports that older adults with type 2 diabetes maintained gains in upper- and lower-body strength over 12 months. However, those gains occurred in the group receiving moderate weight loss plus resistance training; the paper does not establish that caloric restriction alone maintained strength. This source supports the sentence’s maintenance portion, not its reduction portion. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Home-based resistance training following supervised, gym-based training may be less effective for maintaining BG control but adequate for maintaining muscle mass and strength.

    “Home-based resistance training following supervised, gym-based training may be less effective for maintaining BG control but adequate for maintaining muscle mass and strength”

    From Exercise and Type 2 Diabetes (2010) · cites this paper as [66]

  • There is only one relevant previous study of home-based resistance exercise, which was in the weight maintenance phase and found that such exercise had no effect on fat free mass.

    “There is, to our knowledge, only one relevant previous study of home-based resistance exercise, although this was in the weight maintenance phase which, similar to the current study, found that such exercise had no effect on fat free mass [47].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
