Abstract

BACKGROUND

Women with polycystic ovary syndrome (PCOS) experience general and PCOS-specific barriers that limit their engagement with exercise and contribute to high attrition from exercise programs, hindering the potential benefits of exercise to address their increased cardio-metabolic risk. A positive remembered affective response can predict future intentions and adherence to exercise prescription.

OBJECTIVES

To compare the longitudinal changes in remembered affect to high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) in women with PCOS and to determine whether longitudinal changes in remembered affect are correlated with changes in fitness, body mass index, adherence and exercise enjoyment.

METHODS

Physically inactive, overweight women with PCOS were randomly assigned to 12 weeks of either HIIT (n = 15) or MICT (n = 14) (3 sessions per week). Remembered affective valence (Feeling Scale) was collected after each exercise session. Cardiorespiratory fitness (VO) was assessed at baseline and post-intervention. Exercise enjoyment was assessed post-intervention.

RESULTS

The longitudinal changes in the remembered affect were more positive in the HIIT group compared to MICT (β = 0.017, p = 0.047). HIIT was also considered more enjoyable than MICT (p = 0.002). Adherence was high in both groups (>90%). We found a moderate correlation with longitudinal changes between the remembered affect and change in fitness (r = 0.398) and exercise enjoyment (r = 0.376) using the combined group, however, these were not statistically significant (p = 0.054 and p = 0.064, respectively).

CONCLUSIONS

HIIT demonstrated a more positive longitudinal remembered affective response and greater exercise enjoyment compared to MICT in overweight women with PCOS.

摘要

背景

多囊卵巢综合征（PCOS）女性在参与运动时会遇到普遍存在的障碍和 PCOS 特异性障碍，这导致她们从运动计划中大量流失，从而阻碍了运动对她们增加的心血管代谢风险的潜在益处。积极的记忆情感反应可以预测未来的意图和对运动处方的坚持。

目的

比较高强度间歇训练（HIIT）和中等强度持续训练（MICT）对 PCOS 女性的纵向记忆情感变化，并确定记忆情感的纵向变化是否与健康相关因素、体重指数、依从性和运动享受的变化相关。

方法

将身体活动不足、超重的 PCOS 女性随机分为 HIIT 组（n=15）或 MICT 组（n=14），每组每周进行 3 次运动。每次运动后采集记忆情感效价（感觉量表）。在基线和干预后评估心肺功能（VO₂）。干预后评估运动享受度。

结果

与 MICT 相比，HIIT 组的记忆情感变化更为积极（β=0.017，p=0.047）。HIIT 也比 MICT 更受喜爱（p=0.002）。两组的依从性均较高（>90%）。我们发现，在综合组中，记忆情感与健康相关因素变化（r=0.398）和运动享受变化（r=0.376）之间存在中度相关性，但无统计学意义（p=0.054 和 p=0.064）。
