Soyut
Bu çalışma, dinlenme sırasında ve orta dayanıklılık egzersiz sonrası iyileşme döneminde insan kardiyovasküler ve endokrin sistemler üzerindeki olumsuz hava iyon maruz kalmanın etkileri incelenmiştir. On sağlıklı yetişkin erkek varlığı (8000-10000 cm-3) veya egzersiz 1 saat sonra negatif hava iyonları (25 derece C,% 50 nem) yokluğu (200-400 cm-3) çalışıldı. Egzersiz düzeyi değiştirilmemiş bir ortamda (22-23 derece C,% 30-35 nem, 200-400 bir bisiklet ergometresi kullanılarak belirlendi deneklerin maksimal oksijen alımı ile karşılaştırıldığında bir% 50-60 yük temsil ayarlandı negatif hava ions.cm-3). Iyileşme döneminde diyastolik kan basıncı (DKB) değerleri onların yokluğunda daha negatif iyonların varlığında anlamlı olarak daha düşüktü. Plazma serotonin seviyelerini (5-HT), dopamin (DA) ve yokluğunda daha negatif iyonların mevcudiyetinde önemli ölçüde daha düşüktü. Bu sonuçlar negatif hava iyonları maruz kalma orta dayanıklılık egzersiz sonrası toparlanma döneminde 5-HT ve DA düzeylerinde DBP ve azalır yavaş bir iyileşme üretilen gösterdi. 5-HT DKB en yavaş iyileşme katkıda bulunduğu düşünülmektedir.

Abstract
This study examined the effects of negative air ion exposure on the human cardiovascular and endocrine systems during rest and during the recovery period following moderate endurance exercise. Ten healthy adult men were studied in the presence (8,000-10,000 cm-3) or absence (200-400 cm-3) of negative air ions (25 degrees C, 50% humidity) after 1 h of exercise. The level of exercise was adjusted to represent a 50-60% load compared with the subjects' maximal oxygen uptake, which was determined using a bicycle ergometer in an unmodified environment (22-23 degrees C, 30-35% humidity, 200-400 negative air ions.cm-3). The diastolic blood pressure (DBP) values during the recovery period were significantly lower in the presence of negative ions than in their absence. The plasma levels of serotonin (5-HT) and dopamine (DA) were significantly lower in the presence of negative ions than in their absence. These results demonstrated that exposure to negative air ions produced a slow recovery of DBP and decreases in the levels of 5-HT and DA in the recovery period after moderate endurance exercise. 5-HT is thought to have contributed to the slow recovery of DBP.
