    Notes: Summary The influence of exercise on glycaemia in the post-prandial state was studied for the first time in non-insulin-dependent diabetic (NIDDM) patients. Meal-induced glucose responses were followed for 8 h in 9 diet-treated patients with NIDDM. Subjects consumed a standardized breakfast and 4 h later a standardized lunch. They were studied in the resting state (control day (CD)) and on another day 45 min of bicycle exercise (53 ± 2 % V˙O 2 max (mean ± SEM)) was performed 45 min after breakfast (exercise day (ED)). On day 3 (diet day (DD)), the breakfast meal was reduced corresponding to the extra energy expenditure during the exercise period on ED. Responses were calculated as areas under the plasma concentration curve (AUC) during 4 h after either breakfast (B-AUC) or lunch (L-AUC). B-AUC for glucose was identical on ED (215 ± 63 mmol/l · 240 min) and DD (219 ± 60 mmol/l · 240 min) and on these days lower (p 〈 0.05) than on CD (453 ± 78 mmol/l · 240 min). L-AUC for glucose on CD, ED and DD did not differ significantly. B-AUCs for both insulin and C-peptide were also significantly lower on ED and DD as compared to CD (Insulin: 31337 ± 8682, 26092 ± 6457 and 47649 ± 15046 mmol/l · 240 min, respectively. C-peptide: 99 ± 19, 104 ± 26 and 195 ± 31 pmol/ml · 240 min, respectively). Rate of appearance (Ra) for glucose was unaffected by exercise whereas rate of disappearance (Rd) increased significantly. No differences in Ra or Rd were observed after lunch. In conclusion, postprandial exercise of moderate intensity decreases glycaemia and plasma insulin levels after breakfast in NIDDM patients, but this effect does not persist during and after the following lunch meal. Reduction of breakfast caloric intake has the same effect on postprandial glycaemia and insulin secretion as an equivalent exercise-induced increase in caloric expenditure.

    Notes: Abstract The myosin heavy chain (MHC) composition of single fibres from m. vastus lateralis of five spinal- cord-injured (SCI) individuals was analysed by Sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) before, and after 6 and 12 months of functional electrical stimulation (FES)-training, administrated for 30 min three times per week. Prior to FES training 37.2% of the fibres contained only MHC IIB, 21.2% only MHC IIA, and 40.7% co-expressed MHC IIA and MHC IIB. After 6 months of FES-training the number of fibres containing only MHC IIB was reduced to 2.6% (P 〈 0.05), the number of fibres containing only MHC IIA was increased to 44.3% (P 〈 0.05), and the number of fibres co-expressing MHC IIA and MHC IIB was 50.9% (ns). After 12 months almost all fibres (91.2%, P 〈 0.05) contained only MHC IIA. The number of fibres containing only MHC IIB was 2.3% and the fibres co-expressing MHC IIA and IIB had decreased to 4.6% (P 〈 0.05). The amount of fibres containing only MHC I never exceeded 0.5%. Likewise, the number of fibres co-expressing MHC I and MHC IIA was below 2% throughout the study period. In total, the MHC composition of 1596 single fibres was determined. This study shows that FES-training of paralysed human skeletal muscle administrated over a prolonged period of time, can lead to a marked switch in MHC expression from about equal amounts of MHC IIA and MHC IIB to an almost total dominance of MHC IIA.
