The effect of endurance training on the neovascularization of skeletal musculature

Abstract

Purpose:To quantify the capillaries in the skeletal muscular tissue of mice with induced peripheral arterial insufficiency, after endurance training. Methods: It was used Wistar mice in 70 days age range, subjected to the total occlusion of right femoral artery. The animals were divided into two groups: sedentary group (SG; n = 05), subjected to activities in the cage; and trained group (TG; n = 05), subjected to an endurance training in cycle ergometer twice a day 17m/min, by 5 minutes, 5 days per week during 10 weeks. The analysis was realized by the histologic observation of the vastus medialis muscle of injured member. Results: The average number of capillaries in the muscular tissue was greater in TG (5,2 ± 0,83) than in SG (1,6 ± 1,14) (p < 0,05). Conclusion: In animals with induction of peripheral arterial insufficiency, the endurance training provides a process of muscular adaptation which is observed by the increase in the number of capillaries of animals subjected to this kind of training.

Spectroscopic and histological evaluation of wound healing progression following Low Level Laser Therapy (LLLT)

“…In rabbits, higher number of fibroblast proliferation was reported following laser irradiation in early stages of wound healing [88]. Similarly, Carvalho and his co-workers [89] demonstrated the influence of He--Ne laser in accelerated granulation tissue formation and fibroblast activity in diabetic and non-diabetic rats. In another study with 670 nm laser irradiation has reported enhanced collagen and elastin fiber deposition as evidenced by the histological observations during the early phases of wound healing in Wistar rats [13].…”

Effect of Aerobic Exercise Training on Ventilatory Efficiency and Respiratory Drive in Obese Subjects

“…Thus, aerobic training helps improve blood perfusion of the respiratory muscles. 57 The increase in blood perfusion, following endurance training, is the result of an increase in capillarization, mitochondrial density, 58 activities of oxidative enzymes, and reverse metabolic and histological abnormalities of respiratory muscles. 57 The improvement in P Imax is strongly related to a combination of 3 factors: weight, waist circumference, and nutrition.…”

Physiotherapeutic intervention in peripheral arterial disease by functional hyperemia in diabetic patients

“…Supervised exercise programs are currently considered as first-line therapy for patients with peripheral arterial disease (20), and aerobic exercise programs are also widely recommended (13,32,33).…”
