Effects of Performing Resistance Exercise Before Versus After Aerobic Exercise on Glycemia in Type 1 Diabetes

Abstract

OBJECTIVETo determine the effects of exercise order on acute glycemic responses in individuals with type 1 diabetes performing both aerobic and resistance exercise in the same session.RESEARCH DESIGN AND METHODSTwelve physically active individuals with type 1 diabetes (HbA1c 7.1 ± 1.0%) performed aerobic exercise (45 min of running at 60% V̇o2peak) before 45 min of resistance training (three sets of eight, seven different exercises) (AR) or performed the resistance exercise before aerobic exercise (RA). Plasma glucose was measured during exercise and for 60 min after exercise. Interstitial glucose was measured by continuous glucose monitoring 24 h before, during, and 24 h after exercise.RESULTSSignificant declines in blood glucose levels were seen in AR but not in RA throughout the first exercise modality, resulting in higher glucose levels in RA (AR = 5.5 ± 0.7, RA = 9.2 ± 1.2 mmol/L, P = 0.006 after 45 min of exercise). Glucose subsequently decreased in RA and increased in AR over the course of the second 45-min exercise bout, resulting in levels that were not significantly different by the end of exercise (AR = 7.5 ± 0.8, RA = 6.9 ± 1.0 mmol/L, P = 0.436). Although there were no differences in frequency of postexercise hypoglycemia, the duration (105 vs. 48 min) and severity (area under the curve 112 vs. 59 units ⋅ min) of hypoglycemia were nonsignificantly greater after AR compared with RA.CONCLUSIONSPerforming resistance exercise before aerobic exercise improves glycemic stability throughout exercise and reduces the duration and severity of postexercise hypoglycemia for individuals with type 1 diabetes.

Quantifying the Acute Changes in Glucose with Exercise in Type 1 Diabetes: A Systematic Review and Meta-Analysis

“…Of the remaining 17 articles, we decided not to include another eight studies in our meta-analysis due to three reasons that were identified post hoc, namely: (1) in five studies [20][21][22][23][24], patients were supplied with rescue dextrose or carbohydrates, which meant that glucose profiles were artificially altered by these emergency interventions; (2) two studies [25,26] consisted of a single 10 s sprint at the beginning/end of a session and could not therefore be strictly considered to be either CONT or IHE; and (3) one study [27] did not provide any data about inter-subject variability (mean population profiles only were given). During the process of peer review for this report, journal reviewers identified one extra study that fulfilled our inclusion criteria: Yardley et al [28].…”

Análisis del entrenamiento resistido en el perfil glicémico: una revisión bibliográfica

“…La actividad física regular está asociada a una mayor longevidad y a una menor frecuencia de dolencias, siendo que, su práctica ayuda en el control glicémico, lo que es esencial para prevenir varias complicaciones relacionadas a la diabetes, como por ejemplo: la ceguera, diá-lisis, amputaciones y dolencias cardiovasculares que afectan la calidad de vida (Ishiguro et al, 2015;Little et al, 2011;Yardley et al, 2012). A finales del siglo pasado hubo un aumento explosivo de la expectativa de vida en todo el mundo, principalmente en los países desarrollados (Almeida, Silva, Santini, & Dos-Reis, 2012;Paula, Cunha, & Tufanin, 2014), y en la medida que el organismo va envejeciendo hay una alteración en el funcionamiento de varios sistemas orgánicos y también diminución de la masa muscular y como consecuencia pérdida de la fuerza muscular, diminución da función cardiorrespiratoria, dislipidemias y mayor resistencia a la insulina (Geirsdottir et al, 2015;Reis, Vitto, Vieira, & Voltarelli, 2013).…”

Physical activity of the children and adolescents with diabetes mellitus type 1

“…75% badanych uznało, że wysiłek fizyczny pozytywnie wpływa na kontrolę cukrzycy. Pacjenci chorujący krócej niż 2 lata częściej podkreślali (aż 92%) korzystny wpływ wysiłku na kontrolę choroby, jakkolwiek nie wykazano znamiennej korelacji pomiędzy czasem poświęcanym na aktywność fizyczną a poziomem HbA1c (r=0,68, p=0,5), BMI SDS (p>0,05, r=0,2), ani dobowego zapotrzebowania na insulinę (p>0,05, r=0,06).
