| description | Purpose
The aim of this study was to examine whether differences in vascular responsiveness associated with training status would be more prominent in the trained limb (leg) than in the untrained limb (arm) microvasculature.
Methods
Thirteen untrained (26 ± 5 year) and twelve trained (29 ± 4 year) healthy men were submitted to a vascular occlusion test (VOT) (2 min baseline, 5 min occlusion, and 8 min re-oxygenation). The oxygen saturation signal (StO
2
) was assessed using near-infrared spectroscopy (NIRS) throughout the VOT. Vascular responsiveness within the microvasculature was evaluated by the re-oxygenation Slope 2 (Slope 2 StO
2
) and the area under the curve (StO
2AUC
) of (StO
2
) signal during re-oxygenation in the leg and arm.
Results
There was a significant interaction between training status and limb for the slope 2 StO

The aim of this study was to examine whether differences in vascular responsiveness associated with training status would be more prominent in the trained limb (leg) than in the untrained limb (arm) microvasculature.

Thirteen untrained (26 ± 5 year) and twelve trained (29 ± 4 year) healthy men were submitted to a vascular occlusion test (VOT) (2 min baseline, 5 min occlusion, and 8 min re-oxygenation). The oxygen saturation signal (StO

Results
There was a significant interaction between training status and limb for the slope 2 StO
2
(
P
< 0.01). The leg of the trained group showed a steeper slope 2 StO
2
(1.35 ± 0.12% s
−1
) when compared to the slope 2 StO
2
of the leg in their untrained counterparts (0.86 ± 0.09% s
−1
) (
P
< 0.05). There was a medium effect size of 0.58 for slope 2 StO
2
on the arm and a large effect size of 1.21 for slope 2 StO
2
on the leg. In addition, there was a small effect size of 0.24 for StO
2AUC
on the arm and a medium effect size of 0.64 for StO
2AUC
on the leg.
Conclusion
The present study suggests that the vascular adaptations induced by lower limb endurance exercise training are more prominent in the trained limb than in the untrained limb microvasculature.</description><identifier>ISSN: 1439-6319</identifier><identifier>EISSN: 1439-6327</identifier><identifier>DOI: 10.1007/s00421-018-3955-3</identifier><identifier>PMID: 30073561</identifier><language>eng</language><publisher>Berlin/Heidelberg: Springer Berlin Heidelberg</publisher><subject>Adaptation ; Adult ; Arm ; Arm - blood supply ; Biomedical and Life Sciences ; Biomedicine ; Case-Control Studies ; Exercise - physiology ; Human Physiology ; Humans ; I.R. radiation ; Infrared spectroscopy ; Leg ; Leg - blood supply ; Male ; Microcirculation ; Microvasculature ; Occlusion ; Occupational Medicine/Industrial Medicine ; Original Article ; Oxygenation ; Spectroscopy, Near-Infrared ; Spectrum analysis ; Sports Medicine ; Young Adult</subject><ispartof>European journal of applied physiology, 2018-10, Vol.118 (10), p.2241-2248</ispartof><rights>Springer-Verlag GmbH Germany, part of Springer Nature 2018</rights><rights>European Journal of Applied Physiology is a copyright of Springer, (2018).
