Objective of the study was to assess the influence of various types of muscle tension on lower limb blood flow and external respiration rates of skilled boxers when they perform punches.
Methods and structure of the study. Two equivalent groups were involved in the study: Experimental and Control, consisting of 15 19-23 year-old boxers of the first category each.
The athletes were subjected to a loading test: a series of maximum-force straight blows on a boxing bag to be performed within one round (3 min) at 5-sec rest intervals between the series.
The data obtained were processed using the Statistica 10.0 software package. The significance of differences was assessed using the non-parametric Mann-Whitney test.
Results and conclusions. The findings showed that the straight blow performance by means of the ballistic muscle tension type using the sports outfit that limits the traumatic impact on the hands contributes to the more adequate functioning of the external respiration system and regional blood flow. The improvement of the speed-strength capabilities of the muscles involved in the single punch movement using the standard sports outfit does not contribute to the optimal recovery and motor training of skilled boxers.

Keywords: lung volume rates, regional blood flow in muscles, sports training, muscle tension type.
