Response To Exercise

Background: The purpose of this study was to evaluate the role of ventilatory parameters in maximal exercise performance in elite soccer players. Methods: From September 2009 to December 2012, 90 elite soccer players underwent evaluation of lung function test and ergospirometry by means of an incremental symptom-limited treadmill test. Results were analyzed according to i) maximal exercise velocity performed (Hi-M: high-performers, >18.65 km/h; Lo-M: low-performers, <18.65 km/h) and ii) usual role in the team. Results: Hi-M showed higher peak minute ventilation (V_ Epeak: 158.3 ± 19.5 vs 148.0 ± 18.54 L/min, p = 0.0203), and forced expiratory volume at first second (5.28 ± 0.50 vs 4.89 ± 0.52 liters, p < 0.001) than Lo-M, independently of playing role. Moreover, a significant correlation between peak oxygen uptake and V_ E (r = 0.57, p < 0.001) was found. Conclusions: Ventilatory response plays a role in the assessment of exercise capacity in elite soccer players.

Carotid Body Denervation

In three previously reported studies, we had documented that the normal exercise hyperventilation in ponies is accentuated by carotid body denervation (CBD), not affected by hilar nerve pulmonary vagal denervation (HND), and mildly attenuated by spinal cord ablation of the dorsal lateral columns at L2 (SA). In the present study, we hypothesized that if redundancy of control existed in exercising ponies, then multiple denervations of theoretically important pathways in the same animal might attenuate the ventilatory response to exercise in a way not predictable by the individual lesion experiments alone. There were three major findings in the various combinations of CBD, HND, and SA in ponies during treadmill exercise. First, the combination of CBD with HND or SA resulted generally in an accentuation of the hypocapnia during exercise that was predictable on the basis of CBD alone. However, in one pony that showed a hypercapnic exercise response after SA alone, CBD subsequently caused a greater exercise hypercapnia. Second, HND in a CBD or SA pony did not affect the exercise arterial PCO2 response, which is consistent with previous data showing the lack of an HND effect in otherwise intact ponies. Third, in ponies with all three denervations together, the predominant response was an increase, not a decrease, in the exercise hyperventilation; this increase was greater than that predicted from the individual lesions. We conclude that these data do not provide evidence of redundancy in mechanism for the exercise hyperpnea other than instances of carotid chemoreceptor error sensing when hypercapnia occurs during exercise.

Purpose:To compare the response to physical exercise between subjects with spinal cord injury (SCI) and able-bodied (AB) subjects with the objective of developing a new formula for the indirect calculation of oxygen consumption (VO2).Subjects:20 individuals with paraplegia below Th6and 22 AB subjects have participated in the study.Measures:A graded work test was performed on an arm ergometer, starting with 10 w and increasing the power in 10 w each minute up to maximal effort. SCI group present a lower response to the different workloads with respect to the AB group.Results:In the SCI group, a statistical association was found between workload and VO2(r = 0.956,P< 0.001). The proposed equation to calculate the theoretical VO2was the following: 0.487 + (0.013 · watts performed).Conclusions:SCI males, respect to AB subjects, show differences in ventilatory response to exercises. We propose a new formula for the indirect calculation of VO2in relation to workload.
