Background. Regular phys­i­cal activ­ity ­plays a ­role in pre­ven­tive med­i­cine. Our ­study ­aimed at estab­lish­ing the dura­tion of dif­fer­ent lev­els of exer­cise inten­sity dur­ing a ­round of ­golf.
Methods. Participants: we stud­ied 21 ­male and 9 ­female golf­ers (­mean age 53±11 and 54±13 ­years respec­tive­ly) vol­un­teer­ing for a ­round of ­golf on a ­hilly ­course. Measures: we record­ed ­mean ­heart ­rate (HR) of eve­ry 15 sec­onds. Blood pres­sure was tak­en on ­each tee. Maximum HR (HRmax) ­reserve of ­each sub­ject was cal­cu­lat­ed ­from the dif­fer­ence ­between pre-exer­cise and max­i­mum HR ­attained dur­ing a ­test to voli­tion­al exhaus­tion on a ­cycle ergom­e­ter. A per­cent­age of ­this val­ue was add­ed to the rest­ing HR and was ­expressed as a per­cent­age of HRmax ­reserve.
Results. Before ­start ­mean HR (±SD) was 86±11 ­beats per min­ute (BPM), dur­ing ­play 113±18, and dur­ing ­rest ­after ­play 100±24 BPM. Mean max­i­mal HR of ­holes ­were 135±21 BPM. Mean sys­tol­ic ­blood pres­sure was 145±30 ­before ­play, 137±31 on ­tees dur­ing ­play and 119±15 mmHg ­after ­play. A ­mean of 82±51 min­utes was ­spent at 50-74% of HRmax ­reserve. 21±27 and 23±38 min­utes ­were ­spent in the two high­er inten­sity class­es. An aver­age of 106±77 min­utes ­were ­spent at or ­above the indi­vid­u­al ­heart ­rate equiv­a­lent of 100 W, the ­mean ­heart ­rate for ­this ­time was 128±17 BPM. Creatine ­kinase (+47%; p<0.001), ­uric ­acid (+9%; p<0.001) and HDL-cho­les­te­rol (+6%; p<0.05) ­increased, triglycerides ­decreased by 18% (p<0.01).
Conclusions. The HR lev­el dur­ing the gol­fround not ­using an ­electric ­cart rel­a­tive to the max­i­mum ­attained on the ergom­e­ter reach­es the exer­cise inten­sity of 50 to >85% HRmax ­reserve for a ­mean of ­over 2 ­hours, ­much long­er ­than the 20-60 min rec­om­mend­ed for endu­rance train­ing.
