Interval Training: A HIIT for RA?

高强度间歇训练(HIIT)在美国运动医学学院最受欢迎的锻炼项目中名列榜首。According to a small study published inArthritis Research & Therapy,it might be just the ticket forrheumatoid arthritis (RA), too.

HIIT is an aerobic, heart-pumping form of exercise where short bursts of maximum effort, usually lasting from 20 to 60 seconds, alternate with less intense recovery periods. Studies suggest that HIIT is as effective at burning calories and improving heart and lung health as steady-state exercises like running or biking. One 2018 meta-analysis found that HIIT was significantly better than moderately intense steady exercise for patients with heart disease.

Only a few small studies have looked atHIIT for people who have RA. On the whole, they showed that participants lost weight, gained muscle and improved their joint health without any increase in inflammation or pain. But researchers at Duke University in Durham, North Carolina, wanted to learn more, including whether HIIT could improve disease activity and immune function.

Smoking, Obesity Make RA Harder to Control

Remission in RA patientscan be harder to achieve in those who are overweight or smoke, according to a recent study. American and Canadian researchers who collected data on more than 1,100 patients receiving standard treatment for RA found that sex (being female),excess weightandsmokingwere not significantly associated with symptom severity early on. However, all three factors influenced how much symptoms improved over time. The most dramatic differences in symptoms were seen in patients who were overweight or obese and smoked, the study found.

计步器能帮助对抗类风湿性关节炎相关的疲劳吗?

根据2015年美国风湿病学会年会上提出的研究,帮助类风湿关节炎(RA)患者对抗疲劳的关键可能是——字面上和象征性地——在公园里散步。来自加州大学旧金山分校(UCSF)的研究人员发现,适度的锻炼可以减少疲劳,而计步器——加上一点指导——有助于增加人们的运动量。

“疲劳是人们最担心的问题之一;它有多种来源和原因。我们从早期的研究中知道,缺乏运动与疲劳有关,”该研究的主要作者、加州大学旧金山分校医学和健康政策教授帕特里夏·卡茨博士说。“我们想要一种简单、可输出、实施障碍少的干预措施。”

Katz and her team measured the activity level of 96 people with RA for one week, and had them fill out questionnaires. Then the participants were randomly divided into three groups. One group was educated on the need to be active. The second group was given a pedometer and a diary to record their daily steps. The third group got a pedometer, a step diary plus personalized daily step targets. The step targets were based on each person’s starting activity level and increased 10%every two weeks. Groups two and three also got phone calls every two weeks to collect the information from their step diaries.
