International Journal of Exercise Science 16(6): 576-586, 2023. The purpose of the study was to investigate the effect of high interval training (HIIT) under mask on forced vital capacity in football players. Fourteen male football players (age 20 ± 2 years) were randomized into the without mask group (CON) or with the 2 difference mask groups [Surgical mask (SM), FFP2 mask (FM)]. HIIT program were implemented six movements in each session three times per week. Body composition, forced vital capacity and percutaneous oxygen saturation test were taken before and after 4 weeks intervention. The results show that forced vital capacity was statistically significant increased with both types of masks (SM: 5.68 ± 1.07 L; FM: 5.26 ± 0.86 L; CON: 4.66 ± 0.48 L, p < 0.01). Additionally, not significant difference in percutaneous oxygen saturation (SpO2) was found, and fat free mass (SM: 54.45 ± 4.01 kg; FM: 57.08 ± 4.38kg; CON: 58.34 ± 1.81 kg, p<0.01) were statistically significant changed with SM and CON but not FM. In conclusion, wearing surgical masks and FFP2 face mask during high-intensity interval exercise showed certain positive impacts on cardiopulmonary function. This short-term high-intensity interval training can be used to improve forced vital capacity performance among football players. This finding can be applied to develop the strength of breathing muscles in the future.
