The purpose of our study was to investigate the differences in the finswimmers' physiological characteristics, as far as gender, the swimming style and the different swimming distance are concerned.
52 finswimmers participated in our study (Age: 17.4 ± 2.1yrs, BMI: 21.8 ± 2.3, body fat: 12.2 ± 4.7%) and were allocated into groups [Gender: Female vs. Male, swimming style: Bifin vs. Surface, and swimming distance: <200 m vs. ≥200 m]. Anthropometric characteristics, handgrip, estimated strength of inspiratory muscles (PI) and pulmonary function parameters (FEV, FVC and PEF) were measured. The Independent T-test was used for statistical comparisons between groups. Multivariate analyses were performed via binary logistic regression.
The results showed differences between groups in gender in PEF (p < 0.05), PI (p < 0.05) and handgrip (p < 0.001) in swimming style in handgrip (p < 0.05), FEV (p < 0.05) and FVC (p < 0.05) and in swimming distance (p < 0.05) in hours/day spent at the gym (p < 0.05) and FVC (p < 0.05). In multivariate analyses handgrip remained an independent predictor of style (OR: 1.154; 95%CI: 1.022-1.303, p = .021), and hours/day spent at the gym was retained as an independent predictor of distance (OR: 131.607; 95%CI: 3.655-4739.441, p = .008).
The data from the present study reveal that handgrip was associated with style, and hours per day spent at the gym were associated with distance.
本研究旨在探讨蹼泳运动员在性别、泳姿和不同游泳距离方面生理特征的差异。
52名蹼泳运动员参与了本研究（年龄：17.4±2.1岁，体重指数：21.8±2.3，体脂：12.2±4.7%），并被分为不同组[性别：女性与男性，泳姿：双蹼与水面，游泳距离：<200米与≥200米]。测量了人体测量学特征、握力、吸气肌估计力量（PI）和肺功能参数（FEV、FVC和PEF）。采用独立样本t检验进行组间统计比较。通过二元逻辑回归进行多变量分析。
结果显示，性别组间在PEF（p<0.05）、PI（p<0.05）和握力（p<0.001）方面存在差异；泳姿组间在握力（p<0.05）、FEV（p<0.05）和FVC（p<0.05）方面存在差异；游泳距离组间在每天在健身房花费的时间（p<0.05）和FVC（p<0.05）方面存在差异。在多变量分析中，握力仍然是泳姿的独立预测因素（比值比：1.154；95%置信区间：1.022 - 1.303，p = 0.021），每天在健身房花费的时间被保留为距离的独立预测因素（比值比：131.607；95%置信区间：3.655 - 4739.441，p = 0.008）。
本研究数据表明，握力与泳姿相关，每天在健身房花费的时间与游泳距离相关。
