The purpose of this study was to compare the differences in enjoyment and affect in response to four weight control intervention protocols over 12 weeks.
Sixty overweight young females were randomised into four intervention groups: repeated sprint training (RST, 6-sec all-out sprint interspersed with 9-sec rest), high-intensity interval training (HIIT) with short interval (HIIT, 1-min effort at 120% V̇O) and long interval (HIIT, 4-min effort at 90% V̇O), and moderate-intensity continuous training (MICT, 60% V̇O) by cycling over 12 weeks. The total workload in each training session in HIIT, HIIT, and MICT was confined to 200 kJ, while it was lower in RST with 57 ± 4 kJ. Enjoyment (Physical Activity Enjoyment Scale, PACES) and affective valence (Feeling Scale, FS) were measured throughout the intervention.
The score of the PACES on average over 12 weeks showed a significant between-group effect that was lower in MICT (80.8 ± 11.8) compared with HIIT (92.5 ± 11.4) and HIIT (96.8 ± 13.9) ( < 0.05). In the 8th week, enjoyment was scored higher in two HIITs compared with MICT. In the 12th week, HIITs and RST were more enjoyable than MICT, where two HIITs were better than RST. The score of FS showed a significant between-group effect that was higher in HIIT (1.5 ± 1.4) compared with HIIT (0.2 ± 1.2) ( < 0.05), but a non-significant time or group-by-time interaction effect. A significant weight loss occurred in three interval training protocols ( < 0.05), but not in MICT. The V̇O significantly increased in four groups without between-group difference.
Interval training, especially the long-interval type, is an enjoyable and pleasant long-term exercise intervention for overweight young women. RST could be an alternative for weight control considering its time efficiency with comparable enjoyment and overall pleasure.
本研究旨在比较12周内四种体重控制干预方案在愉悦感和情感方面的差异。
60名超重年轻女性被随机分为四个干预组：重复冲刺训练（RST，6秒全力冲刺，穿插9秒休息）、短间歇高强度间歇训练（HIIT，以120%的摄氧量进行1分钟运动）和长间歇高强度间歇训练（HIIT，以90%的摄氧量进行4分钟运动），以及通过12周的骑行进行中等强度持续训练（MICT，60%的摄氧量）。HIIT、HIIT和MICT每次训练的总工作量限制在200千焦，而RST较低，为57±4千焦。在整个干预过程中测量愉悦感（身体活动愉悦感量表，PACES）和情感效价（感觉量表，FS）。
12周内PACES的平均得分显示出显著的组间效应，与HIIT（92.5±11.4）和HIIT（96.8±13.9）相比，MICT（80.8±11.8）较低（<0.05）。在第8周，与MICT相比，两种HIIT的愉悦感得分更高。在第12周，HIIT和RST比MICT更令人愉悦，其中两种HIIT比RST更好。FS得分显示出显著的组间效应，与HIIT（0.2±1.2）相比，HIIT（1.5±1.4）更高（<0.05），但时间或组×时间交互效应不显著。三种间歇训练方案均出现显著体重减轻（<0.05），但MICT未出现。四组的摄氧量均显著增加，组间无差异。
间歇训练，尤其是长间歇类型，是一种适合超重年轻女性的愉悦且令人愉快的长期运动干预方式。考虑到RST的时间效率以及相当的愉悦感和总体满意度，它可以作为体重控制的一种替代方法。
