The aim of this study was to examine the physical and training characteristics of recreational marathon runners within finish time bandings (2.5-3 h, 3-3.5 h, 3.5-4 h, 4-4.5 h and >4.5 h).
A total of 97 recreational marathon runners (age 42.4 ± 9.9 years; mass 69.2 ± 11.3 kg; stature 172.8 ± 9.1 cm), with a marathon finish time of 229.1 ± 48.7 min, of whom n = 34 were female and n = 63 were male, completed an incremental treadmill test for the determination of lactate threshold (LT1), lactate turn point (LT2) and running economy (RE). Following a 7-min recovery, they completed a test to volitional exhaustion starting at LT2 for the assessment of [Formula: see text]. In addition, all participants completed a questionnaire gathering information on their current training regimes exploring weekly distances, training frequencies, types of sessions, longest run in a week, with estimations of training speed, and load and volume derived from these data.
Training frequency was shown to be significantly greater for the 2.5-3 h group compared to the 3.5-4 h runners ( < 0.001) and >4.5 h group ( = 0.004), while distance per session (km·session) was significantly greater for the 2.5-3 h group (16.1 ± 4.2) compared to the 3.5-4 h group (15.5 ± 5.2; = 0.01) and >4.5 h group (10.3 ± 2.6; = 0.001). Race speed correlated with LT1 ( = 0.791), LT2 ( = 0.721) and distance per session ( = 0.563).
The data highlight profound differences for key components of marathon running ([Formula: see text], LT1, LT2, RE and % [Formula: see text]) within a group of recreational runners with the discriminating training variables being training frequency and the absolute training speed.
本研究旨在考察在完赛时间分组(2.5 - 3小时、3 - 3.5小时、3.5 - 4小时、4 - 4.5小时和>4.5小时)内的业余马拉松跑者的身体和训练特征。
共有97名业余马拉松跑者(年龄42.4±9.9岁;体重69.2±11.3千克;身高172.8±9.1厘米),马拉松完赛时间为229.1±48.7分钟,其中女性34名,男性63名,完成了递增式跑步机测试以确定乳酸阈(LT1)、乳酸拐点(LT2)和跑步经济性(RE)。经过7分钟恢复后,他们从LT2开始进行力竭测试以评估[公式:见原文]。此外,所有参与者完成了一份问卷,收集有关他们当前训练方案的信息,包括每周跑量、训练频率、训练课类型、一周内最长跑距离,并估算训练速度以及从这些数据得出的负荷和运动量。
与3.5 - 4小时组(<0.001)和>4.5小时组(=0.004)相比,2.5 - 3小时组的训练频率显著更高,而与3.5 - 4小时组(15.5±5.2;=0.01)和>4.5小时组(10.3±2.6;=0.001)相比,2.5 - 3小时组每次训练的距离(千米·次)显著更长。比赛速度与LT1(=0.791)、LT2(=0.721)和每次训练距离(=0.563)相关。
数据突出显示了在一组业余跑者中,马拉松跑关键组成部分([公式:见原文]、LT1、LT2、RE和%[公式:见原文])存在显著差异,具有区分性的训练变量是训练频率和绝对训练速度。
