Effects of aerobic exercise training on the heart rate-work rate relationship and estimation of anaerobic threshold in obese females

Amaç: Bu çalışmanın amacı aerobik egzersizin kalp atım kırılma noktası ile hesaplanan anaerobik eşik üzerine etkilerini incelemek.Hastalar ve Yöntem: On yedi antrenmansız obez denek (beden kitle indeksi 39.5 ± 1.2 kg/m2) elektromanyetik bisiklet ergometre ile çalışmanın başında ve dördüncü haftasının sonunda olmak üzere iki tane artan yüke karşı yapılan egzersiz testini yoruluncaya kadar devam ettirdiler. Bütün denekler hipokalorik diyet tedavisi ile kombine olarak düzenli aerobik egzersiz antrenman programına alındılar (45 dk, 3 defa her hafta, 4 hafta süre ile). Kalp atımı polar monitör ile kaydedildi. Anaerobik eşik ventilasyon-metabolizma ilişkisi ile hesaplandı ve kapiller kan laktat örnekleri ile tespit edildi.Bulgular: Bütün deneklerde kalp atım hızında kırılma noktası gözlenmedi, antrenman öncesi yalnızca dört denek (%23.5) ve antrenman sonrası üç denekte (%17.6) kalp atımında kırılma noktası gözlendi. İlave olarak, kalp atım kırılma noktası anaerobik eşikten sonra oldu: 90.0 ± 7.2 W ve 75.7±6.5 W (P=0.01). Antrenman sonrası, kalp atım hızı-iş gücü ilişkisi yedi denekte değişiklik gösterdi.Sonuç: Bu sonuçlar bize kalp atımındaki kırılma noktasının çoğunlukla görülmediğini, görüldüğünde ise antrenmanlı ve antrenmansız durumda anaerobik eşik ile uyum göstermediğini ortaya koymaktadır.

Aim: The purpose of this study was to assess the effects of aerobic training on the relationship between the heart rate deflection point and anaerobic threshold (AT). Patients and Methods: Seventeen untrained, obese subjects (body mass index: 39.5 ± 1.2 kg/m2) completed 2 incremental ramp exercise tests (15 W/min) up to the point of exhaustion using an electromagnetically-braked cycle ergometer; once at the onset and once at the end of a 4-week period. All subjects participated in a regular anaerobic exercise training programme (45 min, 3 times per-week, for 4 weeks) combined with a hypocaloric diet. Heart rate was recorded with a polar monitor. AT was estimated using the ventilation-metabolism relationship, but was determined from capillary blood lactate samples. Results: Of all the subjects, only 4 (23.5%) had a heart rate deflection during pre-training, while 3 (17.6%) did during post-training conditions. Additionally, the heart rate deflection point overestimated (20.6%) the AT: 90.0 ± 7.2 W vs. 75.7 ± 6.5 W (P = 0.01). After training, the heart rate-work rate relationship changed in 7 subjects. Conclusion: These data indicated that a deflection point in heart rate does not often occur, and, when it does, it does not coincide with AT, either in pre-training or post-training conditions.
