Abstract

The purpose of this study was to examine and compare
the occurrence of exercise-induced arterial hypoxemia (EIAH) in aerobic and
anaerobic trained young female athletes during a maximal exercise test. International
level young female skiers including eight cross-country skiers (17±1.4 years)
and seven alpine skiers (16.1±1.2 years) took part in the study. Maximal oxygen
uptake (VO_2max: ml/kg/min) was determined using an incremental
treadmill exercise test. Oxyhemoglobin saturation (SaO₂%) was continuously measured using a Pulse oximetry at
rest and during the test. EIAH was assumed to have developed when SaO₂
decreased by at least 4% (ΔSaO₂≤ −4%) from the baseline values. VO_2max,
maximal minute ventilation (L/min), maximal running speed, test duration and
maximal heart rate values were higher in the cross-country skiers than in the
alpine skiers (p< 0.05). All the
athletes in both groups exhibited EIAH. SaO₂ was significantly
decreased from 97.7±1.3% at rest to 87±3.4% at exhaustion in alpine skiers and
from 98.1±0.3% at rest to 88±2.8% at exhaustion in cross-country skiers (p< 0.01). It has been found that
there is no statistically significant difference between the resting and lowest
SaO₂% values of the two groups (p>
0.05). It was determined that arterial hypoxemia occurred during exercise in
anaerobic and aerobic trained athletes. Well-trained young female athletes who
have different aerobic fitness levels may exhibit similar EIAH during the
incremental maximal exercise.

AEROBİK VE ANAEROBİK ANTRENMANLI GENÇ KADIN SPORCULARDA EGZERSİZLE OLUŞAN HİPOKSEMİ

Abstract

Bu
çalışma ile, aerobik ve anaerobik antrenmanlar yapan genç kadın sporcularda maksimal
egzersiz sırasında egzersizle oluşan arteriyel hipoksemi (EOAH) düzeylerini
tespit amaçlandı. Araştırmaya, uluslararası düzeyde yarışmalara katılan sekiz
genç kadın kros kayakçısı (17±1.4 yaş) ve yedi genç kadın alp kayakçısı (16.1±1.2
yaş) katıldı. Maksimal oksijen alımı (VO_2max: ml/kg/dak) koşu
bandında şiddeti giderek artan egzersiz protokolü uygulanarak tespit
edilmiştir. Oksijen saturasyonu (%SaO₂) istirahatte ve test
süresince sürekli olarak Pulse oksimetre kullanılarak ölçülmüştür. EOAH, SaO₂’nin
istirahat düzeyinden en az % 4 (ΔSaO2≤–%4) azalması şeklinde tanımlanmıştır. Kros
kayakçılarının VO_2max, maksimal dakika ventilasyonu (L/dak),
maksimal koşu hızı, test süresi ve maksimal kalp atım hızı değerleri alp
kayakçılarına göre yüksek düzeyde anlamlı bulundu (p< 0.05). Her iki gruptaki tüm sporcularda EOAH görüldü. SaO₂
değerlerinin Alp kayakçılarında % 97.7±1.3 dinlenim düzeyinden % 87±3.4’e
düştüğü, kros kayakçıların ise % 98.1±0.3 dinlenim düzeyinden % 88±2.8’e
düştüğü tespit edildi (p< 0.01).
İki grubun dinlenim ve en düşük % SaO₂ değerleri arasında anlamlı
fark olmadığı tespit edildi (p>
0.05). Anaerobik ve aerobik antrenmanlar yapan sporcularda egzersiz sırasında
arteriyel hipoksemi ortaya çıktığı tespit edildi. Bu çalışmanın sonuçları
farklı
aerobik uygunluk düzeylerine sahip iyi antrenmanlı genç kadın sporcuların,
maksimal egzersiz sırasında benzer EOAH sergileyebileceğini göstermiştir.
