Abstract



The purpose of this study was
to compare the isocapnic buffering phase in young female cross-country skiers
and alpine skiers. International level young female skiers including ten
cross-country skiers and eight alpine skiers took part in the study. Maximal
oxygen uptake (VO2max), ventilatory threshold (VT) and respiratory
compensation point (RCP) were determined using an incremental treadmill
exercise test. VT and RCP were determined using the V-slope method. The
isocapnic buffering (ICB) phase was calculated as the difference in VO2
(ICBVO2) and running speed (ICBSPEED) between RCP and
VT and expressed in either absolute or relative values. The values of VO2,
heart rate, and running speed corresponding to the VT and RCP were
identified. Relative VT and RCP values were recorded as a percentage of VO2max
and maximal running speed. Time to exhaustion was determined as the total
duration of the test. VO2max, maximal running speed, time to
exhaustion, both absolute and relative VT values and absolute RCP values were
higher in the cross-country skiers than in the alpine skiers (P<0.05),
whereas relative RCP showed similar values in both group (p>0.05).
Absolute ICBSPEED showed similar values in both group (p>0.05),
whereas absolute and relative ICBVO2 and relative ICBSPEED
were found to be significantly higher in alpine skiers than in cross-country
skiers (P<0.05). The results of this study indicated that the aerobic
capacity and ventilatory threshold lower in alpine skiers than in
cross-country skiers, while the isocapnic buffering phase and the
high-intensity exercise tolerance were higher in alpine skiers.

Abstract



Bu çalışma, genç
kadın kros ve alp kayakçılarının izokapnik tamponlama faz değerlerini
birbirleriyle karşılaştırmak amacıyla çalışılmıştır. Araştırmaya, uluslararası
düzeyde yarışmalara katılan 10 genç kadın kros kayakçısı ve 8 genç kadın alp
kayakçısı katılmıştır. Maksimal oksijen alımı (VO2max), solunumsal
eşik (SE) ve solunumsal kompenzasyon noktası (SKN) değerleri [1]koşu
bandında şiddeti giderek artan egzersiz test protokolü uygulanarak tespit
edilmiştir.SE ve SKN değerleri V-Slope yöntemi ile belirlenmiştir. İzokapnik
tamponlama (İKT) fazı, SKN ile SE arasındaki fark olarak hesaplandı ve hem
mutlak hem de göreceli VO2 (İKTVO2) ve koşu hızı (İKTHIZ)
değerleri ile ifade edildi. SE ve SKN karşılık gelen VO2, kalp atımı
hızı ve koşu hızı tespit edilerek, VO2max’nin ve maksimal koşu
hızının yüzdesi cinsinden görece değerleri hesaplandı. Tükenme zamanı testin
toplam süresi olarak belirlendi.Kros kayakçıları VO2max, maksimal
koşu hızı, tükenme zamanı, hem mutlak hem de göreceli SE değerleri ve mutlak
SKN değerleri alp kayakçılarına kıyasla anlamlı olarak yüksek bulunurken
(P<0.05), görece SKN değerleri arasında istatistiksel olarak anlamlı fark
görülmedi (p>0.05). Hem mutlak hem de görece İKTVO2 değerleri alp
kayakçılarında kros kayakçılarına kıyasla istatistiksel olarak daha yüksek
bulundu (p<0.05). Görece İKTHIZ değerleri alp kayakçılarında kros
kayakçılarına kıyasla anlamlı olarak yüksek bulunurken (p<0.05), mutlak İKTHIZ
değerleri iki grupta istatistiksel olarak benzerlik gösterdi (p>0.05).
Araştırma bulgularımız, alp kayakçıların kros kayakçılarına kıyasla aerobik
kapasitelerinin daha düşük ve solunumsal eşiğe daha erken girdiklerini, öte
yandan izokapnik tamponlama fazlarının daha geniş ve eşik sonrası egzersize
toleranslarının daha yüksek olduğunu göstermiştir.
