INTENSITY MEASURED BY HEART RATE RESPONSES DURING SKI SCHOOL DAY IN LOW SKILLED SKIERS

The exercise intensity in recreational alpine skiers may not be the highest, but the typical skiing day lasts up to eight hours. The health benefits may well be larger than in standard recreational classes which are usually attended three times a week. The aim of this study was to examine intensity zones and heart rate responses to one typical day of ski school followed with free skiing. Fifteen male low skilled skiers, age 20-22 who were skiing in the morning hours with a ski teacher and in the afternoon freely, were equipped with heart rate monitors during the whole day in order to examine the heart rate responses and calculate the amount of time spent in each exercise intensity zone. HRmax was estimated according to Jackson et al. as 206.9 - (0.67 x age). Five intensity zones were identified according to estimated HRmax values corresponding to: Zone 1 at 50-60% of HRmax ; Zone 2 at 60-70% of HRmax ; Zone 3 at 60-70% of HRmax ; Zone 4 at 70-80% of HRmax and Zone 5 above 90% HRmax. The subjects spent 57% of the 8 hours of recorded time as active, meaning 4 and a half hours above 50% of HRmax (mean HR 105±4, 6 bpm). Most of that active time was spent in aerobic extensive zone (health improvement) and only 5 % of the total time as higher intensity exercise. Those 5% of higher intensity equaled 24 minutes, which should be considered important in a daily exercise routines. According to zones the average percentage of time was as follows: Passive time=42% ; Zone 1= 34, 8% ; Zone 2=18% ; Zone 3= 4% ; Zone 4= 1% and Zone 5 =0, 2%. The results show that the intensities during a standard ski school/free skiing day might have a great potential for health benefits as several hours per day are spent in the intensities that influence cardiovascular and metabolic adaptations, which might be of great benefit in chronic illnesses like hypertension and diabetes. The more experienced skiers might increase intensity by taking “short turn skiing” as suggested by Stoggl et al. (2017). The limitations of the study are linked to the sample that was young and able bodied so in older and less fit subjects the intensities might be higher.
