The purpose of this study was to investigate pacing-profile differences during the 90 km Vasaloppet ski race related to the categories of sex, age, and race experience. Skiing times from eight sections (S1 to S8) were analyzed. For each of the three categories, 400 pairs of skiers were matched to have a finish time within 60 seconds, the same start group, and an assignment to the same group for the other two categories. Paired-samples Student’s t-tests were used to investigate sectional pacing-profile differences between the subgroups. Results showed that males skied faster in S2 (P=0.0042), S3 (P=0.0049), S4 (P=0.010), and S1–S4 (P<0.001), whereas females skied faster in S6 (P<0.001), S7 (P<0.001), S8 (P=0.0088), and S5–S8 (P<0.001). For the age category, old subjects (40 to 59 years) skied faster than young subjects (19 to 39 years) in S3 (P=0.0029), and for the other sections, there were no differences. Experienced subjects (≥4 Vasaloppet ski race completions) skied faster in S1 (P<0.001) and S1–S4 (P=0.0054); inexperienced skiers (<4 Vasaloppet ski race completions) had a shorter mean skiing time in S5–S8 (P=0.0063). In conclusion, females had a more even pacing profile than that of males with the same finish time, start group, age, and race experience. No clear age-related pacing-profile difference was identified for the matched subgroups. Moreover, experienced skiers skied faster in the first half whereas inexperienced skiers had higher skiing speeds during the second half of the race.

在90公里的Vasaloppet滑雪比赛中,性别,年龄和比赛经历对起搏配置文件的影响

这项研究的目的是调查在90 km的Vasaloppet滑雪比赛中与性别,年龄和比赛经历相关的起搏轮廓差异。分析了八个部分(S1至S8)的滑雪时间。对于这三个类别中的每个类别,要对400对滑雪者进行匹配,以使他们在60秒内完成比赛,并拥有相同的开始组,另外两个类别则分配给同一组。配对样本学生t检验用于研究亚组之间的节律性步调差异。结果显示,男性在S2(P = 0.0042),S3(P = 0.0049),S4(P = 0.010)和S1-S4(P <0.001)滑雪得更快,而女性在S6(P <0.001)滑雪得更快。 S7(P <0.001),S8(P = 0.0088)和S5-S8(P <0.001)。对于年龄类别,在S3中,老年受试者(40至59岁)的滑雪速度比青年受试者(19至39岁)的滑雪速度更快(P = 0.0029),其他部分没有差异。有经验的受试者(≥4个Vasaloppet滑雪比赛完成)在S1(P <0.001)和S1-S4(P = 0.0054)中滑雪得更快;经验不足的滑雪者(少于4个Vasaloppet滑雪比赛完成者)在S5–S8中的平均滑雪时间较短(P = 0.0063)。总之,在完成时间,起跑小组,年龄和比赛经验相同的情况下,女性的起搏曲线要比男性更均匀。对于匹配的亚组,未发现明显的年龄相关的起搏曲线差异。此外,经验丰富的滑雪者在上半场滑雪得更快,而经验不足的滑雪者在下半场比赛中具有更高的滑雪速度。有经验的受试者(≥4个Vasaloppet滑雪比赛完成)在S1(P <0.001)和S1-S4(P = 0.0054)中滑雪得更快;经验不足的滑雪者(少于4个Vasaloppet滑雪比赛完成者)在S5–S8中的平均滑雪时间较短(P = 0.0063)。总之,在完成时间,起跑小组,年龄和比赛经验相同的情况下,女性的起搏曲线要比男性更均匀。对于匹配的亚组,未发现明显的年龄相关的起搏曲线差异。此外,经验丰富的滑雪者在上半场滑雪得更快,而经验不足的滑雪者在下半场比赛中具有更高的滑雪速度。有经验的受试者(≥4个Vasaloppet滑雪比赛完成)在S1(P <0.001)和S1-S4(P = 0.0054)中滑雪得更快;经验不足的滑雪者(少于4个Vasaloppet滑雪比赛完成者)在S5–S8中的平均滑雪时间较短(P = 0.0063)。总之,在完成时间,起跑小组,年龄和比赛经验相同的情况下,女性的起搏曲线要比男性更均匀。对于匹配的亚组,未发现明显的年龄相关的起搏曲线差异。此外,经验丰富的滑雪者在上半场滑雪得更快,而经验不足的滑雪者在下半场比赛中具有更高的滑雪速度。与具有相同完成时间,起跑小组,年龄和比赛经历的男性相比,女性的起搏配置更为均匀。对于匹配的亚组,未发现明显的年龄相关的起搏曲线差异。此外,经验丰富的滑雪者在上半场滑雪得更快,而经验不足的滑雪者在下半场比赛中具有更高的滑雪速度。与具有相同完成时间,起跑小组,年龄和比赛经历的男性相比,女性的起搏配置更为均匀。对于匹配的亚组,未发现明显的年龄相关的起搏曲线差异。此外,经验丰富的滑雪者在上半场滑雪得更快,而经验不足的滑雪者在下半场比赛中具有更高的滑雪速度。
