Effects of endurance training on reduction of plasma glucose during high intensity constant and incremental speed tests in Wistar rats 56
Abreu,P.; Vitzel,K.F.; Monteiro,I.C.C.R.; Lima,T.I.; Queiroz,A.N.; Leal-Cardoso,J.H.; Hirabara,S.M.; Ceccatto,V.M..
The aim of this research was to investigate the effects of endurance training on reduction of plasma glucose during high intensity constant and incremental speed tests in Wistar rats. We hypothesized that plasma glucose might be decreased in the exercised group during heavy (more intense) exercise. Twenty-four 10-week-old male Wistar rats were randomly assigned to sedentary and exercised groups. The prescription of endurance exercise training intensity was determined as 60% of the maximum intensity reached at the incremental speed test. The animals were trained by running on a motorized treadmill, five days/week for a total period of 67 weeks. Plasma glucose during the constant speed test in the exercised group at 20 m/min was reduced at the 14th, 21st and...

Limb immobilization alters functional electrophysiological parameters of sciatic nerve 56
Alves,J.S.M.; Leal-Cardoso,J.H.; Santos-Júnior,F.F.U.; Carlos,P.S.; Silva,R.C.; Lucci,C.M.; Báo,S.N.; Ceccatto,V.M.; Barbosa,R..
Immobilization, used in clinical practice to treat traumatologic problems, causes changes in muscle, but it is not known whether changes also occur in nerves. We investigated the effects of immobilization on excitability and compound action potential (CAP) and the ultrastructure of the rat sciatic nerve. Fourteen days after immobilization of the right leg of adult male Wistar rats (n=34), animals were killed and the right sciatic nerve was dissected and mounted in a moist chamber. Nerves were stimulated at a baseline frequency of 0.2 Hz and tested for 2 min at 20, 50, and 100 Hz. Immobilization altered nerve excitability. Rheobase and chronaxy changed from 3.13±0.05 V and 52.31±1.95 µs (control group, n=13) to 2.84±0.06 V and 59.71±2.79 µs (immobilized...
