Abstract
PURPOSE
This cross-sectional study aimed to investigate sex-related glycemic, cardiovascular, and enjoyment responses after intensity-(moderate) and duration-(30 min) matched aerobic (AE) and strength exercises sessions (SE) in type 1 diabetic (T1DM) patients.
METHODS
Twelve volunteers performed randomly three exercise sessions: AE, strength exercises A (SEA) and B (SEB). Heart rate, systolic and diastolic blood pressure, double product (DP) and capillary blood glucose (BG) levels were measured pre (PRE), immediately (POST-0) and 20 min (POST-20) after each exercise session. Rating of perceived exertion and enjoyment level were also measured. A generalized mixed model was used to verify responses over time (p < 0.05). Effect size (ES) was also calculated.
RESULTS
Men shown reduced BG levels (POST-0 and POST-20), besides presenting lower values than women in both time points after AE. BG was found reduced POST-0 (SEA and SEB) and POST-20 (SEA) in men, and POST-0 and POST-20 min (SEA) in women compared to PRE (ES was moderate, large or very large), without causing hypoglycemic episodes. However, no differences between sexes were seen concerning strength sessions. Cardiovascular parameters and enjoyment levels were similar between exercise sessions.
CONCLUSIONS
When aerobic and strength exercise sessions are intensity- and duration-matched, lower glucose levels are seen in men after AE, but similar values are found regarding SE. These findings suggest that sex-specific recommendations may be considered when prescribing exercise for T1DM patients.
