Summary of results for sperm motility percentage. Con: control group, Dia: diabetic group, DiaIns: diabetic and insulin administration group, DiaEx: diabetic and exercise intervention group, DiaInEx: diabetic group with insulin administration and exercise intervention, DiaExE: diabetic and endurance exercise group, DiaExR: diabetic and resistance exercise group, DiaExC: diabetic and combined exercise group. DiaExpre: diabetic group baseline values, DiaExpost: diabetic group post-exercise intervention. *: p < 0.05 between experimental group (exercise, insulin, or both) and diabetic control group. Main comparisons: (a) Con = Ex > DiaIn = DiaInEx = DiaEx > Dia. p < 0.05. (b) Ex (66.1 ± 4.1) > Con (60.8 ± 6.5) > [DiaEx (40 ± 6.5) = Dia (32.5 ± 1.1). p < 0.05. (c) DiaExR (41.4 ± 4.5%) = DiaExC (34.4 ± 2.6%) > Dia (32.5 ± 1.1%). p < 0.05. (d) DiaEx (pre, 57.1 ± 5.4) < DiaEx (post, 63.5 ± 5.8) > Dia (post, 56.3 ± 6.0). p < 0.05.
