Background. Action Pistol Shooting, ­implies ­high ­degree of phys­i­cal and psy­cho­log­i­cal ­stress, how­ev­er car­di­o­vas­cu­lar adap­ta­tion dur­ing com­pe­ti­tion has not ­been stud­ied so far.
Methods. We stud­ied six ­healthy ­males ath­letes, dur­ing the Italian National Dynamic Pistol Shooting Championship. ECG was mon­i­tored and ­blood pres­sure (BP) man­u­al­ly meas­ured ­along the ­match.
Results. Mean ­heart ­rate (HR) was ­close to 100 bpm per min­ute in all but one shoot­ers. Marked tach­y­car­dia, ­above 180 ­beats per min­ute was record­ed in ­four shoot­ers, dur­ing “­field ­course” stag­es. In two cas­es the ­heart ­rate ­under ­stress ­reached ­about 200 bpm, for the occur­rence of par­ox­ys­mal atri­al arrhyth­mi­as. BP behav­ior was dif­fer­ent ­among the six shoot­ers ­with ­mean sys­tol­ic val­ues rang­ing ­between 140 and 170 mmHg and max­i­mal sys­tol­ic val­ues ­between 160 e 240 mmHg.
Conclusions. Action Pistol Shooting induc­es ­acute ele­va­tion of HR and BP, ­which may ­reach abnor­mal val­ues and can be asso­ciat­ed ­with ­impaired per­for­mance and ­score. Further ­study is war­rant­ed in shoot­ers under­go­ing com­bat-­like tour­na­ments to eval­u­ate unper­ceived car­di­o­vas­cu­lar ­stress and ­their cop­ing capa­bil­ity.
