Key result
Endurance training in swimmers was associated with significantly higher maximum inspiratory and expiratory pressures compared to sedentary controls and wrestlers.
Why the study?
To evaluate ventilatory function variables, maximum inspiratory pressure, and maximum expiratory pressure in athletes training strength versus endurance compared with sedentary controls.
Does the type of athletic training (endurance vs strength) affect ventilatory function and respiratory muscle pressures compared to sedentary controls?
Cross-Sectional (n=50)
Does the type of athletic training (endurance vs strength) affect ventilatory function and respiratory muscle pressures compared to sedentary controls?
Endurance training, particularly swimming, induces greater adaptive changes and functional reserves in the respiratory system compared to strength training or sedentary lifestyles.
No immediate clinical implications for patients; cross-sectional data leave causal effects and therapeutic relevance open.
Ventilatory function variables and maximum inspiratory pressure (MIP) and expiratory pressure (MEP) were studied in athletes training strength and endurance. 36 athletes engaged in swimming (n = 12), game sports (n = 12) and wrestling (n = 12); in addition, 14 age-matched and sex-matched sedentary controls were examined. The observed values of MIP and MEP as well as the dynamic ventilatory variables in swimmers were significantly higher than those in control subjects and wrestlers. A close correlation was shown between MIP/MEP and the maximum voluntary ventilation both in the control group (r = 0.86 and r = 0.81 for MIP and MEP, respectively (p < 0.01)) and in the group of wrestlers (r = 0.87 (p < 0.01) and r = 0.66 (p < 0.05)). A weak relationship was found in the group of game players; in the group of swimmers, this relationship was completely nonsignificant. These data allow us to conclude that dynamic exercises in athletes who train endurance and static exercises in athletes who train strength cause different adaptive changes in the ventilatory function. Most of changes and an increase in functional reserves in the respiratory system are observed in athletes who train endurance, especially swimmers. Minimum changes are observed in athletes engaged in different types of wrestling. In this regard, the effectiveness of specific training of the respiratory muscles will be higher in athletes of power and game sports in comparison with athletes engaged in swimming.

Сегизбаева et al. (2021) conducted a cross-sectional in Healthy athletes and sedentary controls (n=50). Different training types (swimming, game sports, wrestling) vs. Sedentary controls was evaluated on Ventilatory function variables, maximum inspiratory pressure (MIP), and maximum expiratory pressure (MEP). Endurance training in swimmers was associated with significantly higher maximum inspiratory and expiratory pressures compared to sedentary controls and wrestlers.
