Spirometry is an essential test for assessing the state of the respiratory system. It provides the measurement of the ventilation volumes and fl ows expressed in absolute and relative values. Among elite athletes, the values of ventilation parameters are usually higher than the norm; therefore the interpretation of individual results of elite athletes in relation to the general healthy population is not advisable. Th is study aimed to determine the respiratory characteristics of elite sailors in the Olympic Finn class, and the diff erences between more successful and less successful sailors according to the criterion of sport effi cacy. Th e study included 33 sailors of the Olympic Finn class who participated at the 2015 Finn European Championship. Absolute values of spirometry parameters of elite Finn sailors (FVC-Forced-vital-capacity 5.96±0.79; FEV1-Forced-expiratoryvolume-in-1-second 5.10±0.63; FEV1/FVC%-Forced-expiratory-volume-in-1-second/Forced-vital-capacity 86.10±6.38; MVV-Maximum-voluntary-ventilation 190.94±32.64) are higher than the spirometry values of most other athletes. Relative values of spirometry parameters of elite Finn sailors (FVC% 101.24±14.21; FEV1% 102.53±12.09; FEV1/FVC%% 102.00±7.94; MVV% 96.77±18.59) are within the ranges of most elite athletes. Elite sailors can be considered healthy in terms of ventilation, and sailing as a sports activity can be considered benefi cial for the ventilatory function of the lungs. More successful sailors had higher mean values of absolute and relative ventilation parameters of FVC, FEV1, and MVV, whereas signifi cant diff erences were determined in the variables of MVV. Th e diff erences between more successful and less successful sailors in the MVV and MVV% variables could be interpreted precisely by the state of respiratory muscles.

顶级Finn级水手的呼吸参数

肺活量测定法是评估呼吸系统状态的必要测试。它提供了以绝对值和相对值表示的通风量和流量的测量值。在优秀运动员中，通气参数的值通常高于标准值。因此，最好不要解释精英运动员相对于一般健康人群的个人成绩。这项研究旨在确定奥林匹克Finn班精英水手的呼吸特性，以及根据运动效率的标准来区分成功与失败的水手之间的区别。该研究包括33名奥林匹克Finn级水手，他们参加了2015年Finn欧洲锦标赛。精英Finn水手的肺活量测定参数的绝对值（FVC-强制-生命能力5.96±0.79; FEV1-1秒内呼气量5.10±0.63; FEV1 / FVC％强制呼气量在1秒内/强制生命容量86.10±6.38; MVV-最大自愿通气量190.94±32.64）高于大多数其他运动员的肺活量测定值。精英芬兰水手的肺活量测定参数的相对值（FVC％101.24±14.21; FEV1％102.53±12.09; FEV1 / FVC %% 102.00±7.94; MVV％96.77±18.59）在大多数精英运动员的范围内。优秀的水手在通风方面可以被认为是健康的，而帆船运动是一项体育活动，可以被认为对肺的呼吸功能有益。成功的水手的FVC，FEV1和MVV的绝对和相对通气参数平均值较高，而MVV变量则确定了显着差异。
