Abstract

Research  background  and  hypothesis.  Blood  flow  intensity  plays  an  important  role  in  the  recovery  after
exercising.
Research aim was to compare the effect of passive rest and passive foot movement on calf muscle blood flow
applying dosed static physical loads.
Research methods. Eighteen adult males were divided into two sub-groups. Participants of the study performed
two isometric 30-s workouts at 75% of MVC with 20 minutes interval for the recovery between the workouts. During
the first stage one sub-group performed workout and a passive recovery was applied while the subjects of the second
sub-group performed passive foot flexion movements. During the second stage the form of recovery was changed.  Arterial  blood  flow  intensity  was  registered  during  venous  occlusion  plethysmography  and  passive  foot  flexion  movements were performed by special mechanical equipment.
Research results. The results obtained during the study showed that maximal increase of blood flow registered
at 21 second after the workout was (52.0 ± 2.9 ml/min/100 ml), while the application of passive movements before
the workout decreased the blood flow intensity (45.0  ± 2.6 ml/min/100 ml). It was significantly (p  < 0.05) lower
compared to passive rest.
Discussion and conclusions. These effects can be explained by reduced venous filling and increased venous
vascular reserve capacity in the calves. The results obtained during this research allow concluding that passive
foot flexion manoeuvre applied before the isometric workload faster decreases the blood flow intensity during the  recovery.

Keywords: arterial blood flow recovery, isometric physical workout, passive foot movement, passive rest.
