The COVID-19 pandemic caused significant training disruptions during the 2020-2021 season, due to lockdowns, quarantines, and strict adherence to the pandemic protocols. The main purpose of this study was to determine how the pandemic training restrictions affected training volume and performance in one collegiate swim team. Cumulative training volume data across a 28-week season were compared between a pandemic (2020-2021) versus non-pandemic (2019-2020) season. The swimmers were categorized into three groups (sprinters, mid-distance, and long-distance) based on their training group. The performance times of 25 swimmers who competed in the regional championships, during both the non-pandemic and pandemic year, were compared via one-way ANOVA. Twenty-six male and 22 female swimmers commenced the 2020-2021 (pandemic) season, with 23% of the swimmers voluntarily opting out. Three COVID-19 cases were confirmed (2%) by the medical staff, with no long-term effects. Significant reductions in the average swim volume were verified in sprinters (32,867 ± 10,135 vs. 14,800 ± 7995 yards; < 0.001), mid-distance (26,457 ± 10,692 vs. 17,054 ± 9.923 yards; < 0.001), and long-distance (37,600 ± 14,430 vs. 22,254 ± 14,418 yards; < 0.001) swimmers (non-pandemic vs. pandemic season, respectively). In the regional performance analyses, the sprinters swam faster ( = 8; -0.5 ± 0.6 s), while the mid-distance ( = 10; 0.17 ± 2.1 s) and long-distance ( = 7; 6.0 ± 4.9 s) swimmers swam slower (F = 11.76; = 0.0003; r = 0.52). Thus, the pandemic caused significant reductions in swim training volume, with sprinters performing better and long-distance swimmers performing worse at the regional championships.
2020-2021 赛季，由于封锁、隔离和严格遵守大流行协议，COVID-19 大流行导致训练出现重大中断。本研究的主要目的是确定大流行期间的训练限制如何影响一个大学游泳队的训练量和表现。在 28 周的赛季中，比较了大流行（2020-2021 年）和非大流行（2019-2020 年）赛季的累积训练量数据。根据他们的训练小组，将游泳运动员分为三组（短跑运动员、中距离和长距离）。通过单向方差分析比较了在区域锦标赛中参赛的 25 名游泳运动员在非大流行和大流行年份的表现时间。26 名男性和 22 名女性游泳运动员开始了 2020-2021 年（大流行）赛季，其中 23%的游泳运动员自愿退出。医务人员确诊了 3 例 COVID-19 病例（2%），没有长期影响。短跑运动员（32867 ± 10135 与 14800 ± 7995 码；<0.001）、中距离（26457 ± 10692 与 17054 ± 9.923 码；<0.001）和长距离（37600 ± 14430 与 22254 ± 14418 码；<0.001）游泳运动员的平均游泳量均显著减少（分别为非大流行和大流行赛季）。在区域表现分析中，短跑运动员游得更快（ = 8；-0.5 ± 0.6 s），而中距离（ = 10；0.17 ± 2.1 s）和长距离（ = 7；6.0 ± 4.9 s）游泳运动员游得更慢（F = 11.76； = 0.0003；r = 0.52）。因此，大流行导致游泳训练量显著减少，短跑运动员在区域锦标赛中表现更好，而长距离游泳运动员表现更差。
