Introduction:
There is a lack of knowledge regarding the acute glycemic and blood pressure responses to resistance exercises that involve different amounts of muscle mass.
Objective:
To analyze the acute effects of single- and multi-joint resistance exercises on glycemic control and blood pressure in individuals with type 2 diabetes (T2DM).
Methods:
This is a pilot randomized crossover trial, including adults with T2DM of both genders. The participants performed three sessions (two experimental sessions: one with single-joint exercises (SIN) and the other with multi-joint exercises (MULTI); and a control session (CON)) in a randomized order, with outcomes being evaluated pre-exercise, immediately, 15 and 30 min after the sessions. Both sessions consisted of five exercises performed in three sets of 10 to 12 maximum repetitions. Analyses were performed by generalized estimation equations.
Results:
Fifteen adults (including eleven women) participated in this study. Both experimental sessions showed glycemic reductions immediately after the sessions (MULTI: -17 mg/dL; SIN: -29 mg/dL; p < 0.001), and these values were kept similar up to 30 min after the session. The control session presented a glycemic reduction immediately after the session (-18 mg/dL), which increased 15 min later (-29 mg/dL), stabilizing up to 30 min after the session. Systolic blood pressure was increased immediately after both experimental sessions, retuning to baseline values 15 min post-session. Diastolic blood pressure increased in the control session with time, without any alterations in the experimental sessions.
Conclusions:
Similar glycemic reductions were found in the experimental sessions, without superiority over the control session. Minimal changes were found in blood pressure.

Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
