“…Therefore, the authors suggested that besides height, other factors could have impact upon lung function such as fat free mass, thoracic diameter, and trunk length. [13,23] The present study shows that at maximal exercise, the swimmers and field sports group reached similar V̇O2 peak, ̇ , and workloads, all of which were significantly greater than the recreational group (Table 3). Despite these differences it was found that their ventilatory reserve (̇ expressed as a percent of MVV) were the same at around 20%.…”

“…Whether the different lung volumes and capacities reported in swimmers is due to their training, the result of a genetic predisposition, or a mixture of both, has been investigated in other studies. [11,13,20,27] In support of the importance of genotype, it has been reported that swimmers tend to be taller than age and weight matched peers, and that these anthropometric characteristics are influenced by genetic inheritance. [11].…”

“…[10][11][12] However it is unclear as to whether these differences in lung function are due to a genetic predisposition, or an effect of training. [11,13] The study investigates whether the ventilatory response to exercise in swimmers is different to other athletes. The aim is to compare maximal exercise using cycle ergometry in swimmers and two groups of matched non-swimmers.…”

While the static and dynamic lung volumes of active swimmers is often greater than the predicted volume of similarly active non-swimmers, little is known if their ventilatory response to exercise is also different. Methods: Three groups of anthropometrically matched male adults were recruited, daily active swimmers (n = 15), daily active in fields sport (Rugby and Football) (n = 15), and recreationally active (n = 15). Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and maximal voluntary ventilation (MVV) was measured before and after exercise to volitional exhaustion. Results: Swimmers had significantly larger FVC (6.2 ± 0.6 L, 109 ± 9 % pred) than the other groups (5.6 ± 0.5 L, 106 ± 13 % pred, 5.5 ± 0.8, 99 % pred, the sportsmen and recreational groups respectively). FEV1 and MVV were not different. While at peak exercise, all groups reached their ventilatory reserve (around 20%), the swimmers had a greater minute ventilation rate than the recreational group (146 ± 19 vs 120 ± 87L/min), delivering this volume by breathing deeper and slower. Conclusions: The swimmers utilised their larger static volumes (FVC) differently during exercise by meeting their ventilation volume through long and deep breaths.

“…One could interpret these findings as additional evidence that overweight promotes a lung growth that is different from normal, with a disproportional increase in lung parenchyma (FVC) in comparison to airway (maximal flows and airway resistance). The same pattern of large lungs is seen in swimmers ( 36 ), divers ( 37 ), and other such athletes, as well as subjects living in high altitudes ( 38 ), and these are findings that have no association with respiratory disease. These observations recommend caution to label a lower FEV 1 /FVC as a true obstructive pattern in overweight children.…”

Asthma and Obesity in Children Are Independently Associated with Airway Dysanapsis

BackgroundAn increase in the prevalence of overweight and asthma has been observed. Both conditions affect negatively lung function in adults and children. The aim of this study was to analyze the effect of overweight and asthma on lung function in children.MethodsWe designed a case–control study of healthy and asthmatic subjects nested within an epidemiological asthma prevalence study in children between 8 and 16 years of age. The effect of asthma and overweight on lung function was assessed by impulse oscillometry and spirometry obtained at baseline and 10–15 min after salbutamol.Results188 children were recruited, 114 (61%) were asthmatics and 72 (38%) were overweight or obese. Children with asthma and overweight had a higher FVC (+1.16 z scores, p < 0.001) and higher FEV1 (+0.79 z scores, p = 0.004) and lower FEV1/FVC (−0.54 z scores, p = 0.008) when compared to healthy controls. Compared to normal weight asthmatics, the overweight had higher FVC (+0.78 z scores, p = 0.005) and lower FEV1/FVC (−0.50 z scores, p = 0.007). In the multivariate analysis, overweight was associated with an increase of 0.71 and 0.44 z scores in FVC and FEV1, respectively, and a reduction in FEV1/FVC by 0.40 z scores (p < 0.01 for all). Overweight had no effect on maximal flows and airway resistance at baseline, and this was not modified by inhalation of a bronchodilator. Asthma was also associated with higher post-BD FVC (0.45 z scores, p = 0.012) and FEV1 (0.35 z scores, p = 0.034) but not with FEV1/FVC and FEF25–75%. Two-way analysis of variance did not detect any interaction between asthma and overweight on lung function variables before or after bronchodilator.ConclusionOur results suggest that asthma and overweight are independently associated with airway dysanaptic growth in children which can be further scrutinized using impulse oscillometry. Overweight contributed more to the reduction in FEV1/FVC than asthma in children without increasing airway resistance. Spirometry specificity and sensitivity for obstructive diseases may be reduced in populations with high prevalence of overweight. Adding impedance oscillometry to spirometry improves our understanding of the ventilatory abnormalities in overweight children.

“…Some recent scientific research observed that some particular sport disciplines improve the lung function and the cardiovascular capacity better than others, these include swimming, and, as recently reported, basketball, water polo and rowing (Lazovic et al, 2015;Bougault et al, 2009;Vaithiyanadane et al, 2012). Also swimmers achieve larger lung volumes and higher functional cardiorespiratory system capacity compared to other athletes (Lazovic-Popovic et al, 2016).…”

Nowadays sports success has become more than improving technique, medicine has long been a complementary science technology that improved sports performance. In our study we analyzed the importance of functional training in the military pentathlon at the 50 m swimming with obstacles. The scientific methods used were the observation method and also the experiment method in which we tested two samples of military students both consisted in 30 students with the age between 18-22 years old, the first group were the experiment group that practice the military pentathlon and the second group – the control group – were simple military students. The results showed significant statistical differences between the experiment group compared with the control group at the final testing, the students from the experiment group had better results in the respiratory rate and vital capacity both compared with the control group and also between the initial and final test. Conclusions of the research showed that the training program implemented at the experiment group has improved significant from the initial to the final test and also compared with the control group.
