ABSTRACT
Simple SummaryWearing a face mask can block and reduce the exposure of the oronasopharyngeal region to viruses. It is unclear whether wearing a surgical mask (SM) or a three-dimensional (3D) SM (3DSM) during high-intensity, short-rest resistance exercise could influence the cardiac capacity, pulmonary function, and comfort in weightlifters. Wearing both SM and 3DSM during whole-body, high-intensity, short-rest resistance exercise exerted no detrimental effect on blood pressure (BP) or pulmonary function and promoted postexercise hypotension (PEH). Furthermore, wearing a typical SM during exercise produced higher breathing resistance and tightness than did wearing a 3DSM or no mask.This study investigated the effect of wearing a typical surgical mask (SM) or a three-dimensional (3D) SM (3DSM) during whole-body, high-intensity, short-rest resistance exercise on cardiorespiratory, respiratory, and perceptual comfort responses in weightlifters. Twenty elite weightlifters (6 women and 14 men;age = 24.1 ± 4.9 years;height 167.45 ± 7.60 cm;body mass = 76.48 ± 19.86 kg) who participated in this study performed 3 resistance exercise sessions in a randomized order (1) without a mask (NM), (2) while wearing a typical SM, and (3) while wearing a 3DSM. Resistance exercise consisted of a descending pyramid scheme starting at 10 repetitions, with a decrease of one repetition per set for the back squat, bench press, and deadlift, as fast as possible at 75% of the one-repetition maximum. Cardiorespiratory and pulmonary function and comfort were measured. Across all conditions, effective postexercise hypotension (PEH) was noted in terms of decreased systolic blood pressure (−4.64%), diastolic BP (−5.36%), mean arterial pressure (−5.02%), and ankle–brachial index (−6.84%). However, the heart rate (40.34%) and rate of pressure product (33.60%) increased, and no effects on pulmonary function were observed in the three conditions. The participants reported higher breathing resistance and tightness when wearing a typical SM than when wearing a 3DSM or no mask. Therefore, both wearing and not wearing a face mask during whole-body, high-intensity, short-rest resistance exercise promoted PEH and exerted no detrimental effect on pulmonary function. Coaches, trainers, and athletes should consider wearing a 3DSM during resistance exercise.
