Spennende studie som nevner at blodsirkulasjonen øker i området som har stølhet. Og den økte blodsirkulasjonen vedvarer i mer enn 48 timer etter treningen. I dette tilfellet i leggen som ble trent. De mener det er pga økt betennelse i muskelen.
There was a significant main effect for time for blood volume (p=0.023) and blood flow (p=0.010), with no significant difference in blood flow velocity (p=0.316). There were significant increases in blood volume (p=0.001) and blood flow (p<0.001) immediately postexercise (9.77 ± 3.19 dB and 3.53 ± 0.86 dB/sec), respectfully in the contralateral limb compared to baseline (6.18 ± 2.05 dB and 2.40 ± 0.69), with no change in blood flow velocity (p=0.487). The effect size for blood volume was 1.34 (0.09, 2.60) and blood flow was 1.41 (0.15, 2.68). The increases in contra lateral blood volume (p=0.002) and blood flow (p=0.003) were maintained at 48 hours (9.41 ± 1.90 dB and 3.51 ± 0.47 dB/sec) compared to baseline, with again no change in blood flow velocity (p=0.411). The effect size for blood volume was 1.62 (0.32, 2.92) and blood flow was 1.86 (0.51, 3.22). There were no changes in blood volume (p=0.814), blood flow (p=0.962), or blood flow velocity (p=0.493) between post-exercise and 48 hours for the contra lateral limb.
Following eccentric exercise to a single limb, the contralateral limb resulted in increased blood volume and blood flow immediately after exercise and at 48 hours post exercise. From previous research in our lab  immediately after eccentric exercise, blood volume and blood flow increased in the exercise leg by 42% and 80%, respectfully. From this study, the contra lateral leg increased 17% and 35% for blood volume and blood flow, respectfully. This finding supports earlier work by Seals  and Taylor et al.  that identified vasodilatation of the contra lateral limb after exercise initiation. Blood flow velocity did not change in the contra lateral limb after exercise and at 48 hours. Since this limb was not exercised, recruitment of capillaries is not necessary, as would be in exercised muscle .
Eccentric exercise increased microvascular perfusion immediately after exercise in the contralateral limb, which had not been examined before. The increased perfusion was maintained over 48 hours, so the prolonged increased in perfusion of the contralateral limb may have been due to an inflammatory response or the extra demands placed on the contralateral limb for support during walking.
