In this study, the fast orthograde axonal transport of radiolabeled proteins was measured to determine the effects of endurance-running training on transport velocity and amounts of transported proteins in rat sciatic motoneurons. Female rats were subjected to a progressive running-training program for 10-12 wk. Twenty-four hours after the last training session, rats underwent right L4-L5 dorsal root ganglionectomy. The next day, 20 microCi of [3H]leucine was injected bilaterally in the vicinity of the motoneuronal cell bodies supplying the sciatic nerve, to study axonal transport parameters. Results showed that peak and average transport velocities of labeled proteins were significantly (P less than 0.05) increased by 22 and 29%, respectively, in the deafferented nerves of the runners as compared with controls. Moreover, the amount of total transported protein-bound radioactivity was increased in both left (40%) and right (37%) sciatic nerves of the runners. An exhaustive exercise session reduced (P less than 0.05) peak displacement (8%) and total transported protein-bound radioactivity (36%) in the sciatic nerves of control rats, whereas no changes were noticed in trained animals. The data suggest that chronic endurance running induces significant adaptations in the fast axonal transport of labeled proteins.

The purpose of this study was to examine the effect of endurance training on oxygen uptake (V˙o 2) kinetics during moderate [below the lactate threshold (LT)] and heavy (above LT) treadmill running. Twenty-three healthy physical education students undertook 6 wk of endurance training that involved continuous and interval running training 3–5 days per week for 20–30 min per session. Before and after the training program, the subjects performed an incremental treadmill test to exhaustion for determination of the LT and the V˙o 2 max and a series of 6-min square-wave transitions from rest to running speeds calculated to require 80% of the LT and 50% of the difference between LT and maximal V˙o 2. The training program caused small (3–4%) but significant increases in LT and maximalV˙o 2 ( P < 0.05). TheV˙o 2 kinetics for moderate exercise were not significantly affected by training. For heavy exercise, the time constant and amplitude of the fast component were not significantly affected by training, but the amplitude of theV˙o 2 slow component was significantly reduced from 321 ± 32 to 217 ± 23 ml/min ( P< 0.05). The reduction in the slow component was not significantly correlated to the reduction in blood lactate concentration ( r = 0.39). Although the reduction in the slow component was significantly related to the reduction in minute ventilation ( r = 0.46; P < 0.05), it was calculated that only 9–14% of the slow component could be attributed to the change in minute ventilation. We conclude that theV˙o 2 slow component during treadmill running can be attenuated with a short-term program of endurance running training.

Introduction: The adherence on endurance running events is increasing exponentially around the World in both previously untrained men and women, thus the incorporation of more appropriate and individualized training approaches are required. It is not known if male and female untrained runners differ in the responses to endurance running training on performancerelated variables. Objective: We aimed to compare performance-related responses to an endurance running training program between untrained men and women. Material and method: Sixteen participants (8 men and 8 women) were paired in the baseline by age, body mass index, and percentage in which time to complete 5 km (t5km) represented from the average of best 50 runners t5km in the greatest regional race for each gender. They completed an 11-week training protocol alternating high-intensity interval training and moderateintensity continuous running, three times per week, in a running track. In the week 1 and 11 of the protocol (baseline and post-training weeks), peak running velocity at treadmill (Vpeak), time limit (tlim) at 100% Vpeak, t5km, and the index rMSSD of heart rate variability (HRV) were measured for cardiac autonomic function. Baseline gender-differences were accounted in the analysis. Results: Male and female significantly improved Vpeak (9.4 ± 1.7% and 7.2 ± 1.7%, respectively) and t5km (-13.0 ± 1.8% for both), and no gender-related differences for the adaptations in these two variables were observed. The tlim at 100% Vpeak and rMSSD did not change across the training period in both groups. Percentage of change for men was “moderately” higher than for women for rMSSD (33.4 ± 40.7% vs. 13.9 ± 21.4%), although statistically non-significant. Conclusion: Men and women responses to training were similar with regards to their running performance and cardiac autonomic function. With regards to practical application, Vpeak and its tlim can be applied in exercise settings for the prescription of moderate- to high-intensity running training with similar benefits regardless of the biological gender
