A new study from Nanyang Technological University (NTU) in Singapore has challenged the common assumption that exercising with a spouse is the most effective way to boost physical activity levels in older adults. The study, published in the journal Journal of Medical Internet Research, found that older adults who exercised with their spouse achieved lower physical activity levels than those who exercised individually.

The researchers analyzed data from 240 participants in Singapore aged 54 to 72 years old who were enrolled in a 12-week exercise intervention program. Half of the participants were randomly assigned to exercise with their spouse, while the other half exercised individually. All participants were provided with fitness trackers to monitor their daily activity levels.

The results of the study showed that participants who exercised with their spouse had lower mean and median step counts than those who exercised individually. They also met the recommended daily step counts of 7,500, 10,000, and 15,000 less frequently than those who participated alone.

The researchers believe that there are several possible explanations for these findings. One possibility is that couples may have different exercise preferences and goals, making it difficult to find an activity that both partners enjoy and are committed to. Additionally, couples may be more likely to compromise on exercise intensity or duration when exercising together, leading to lower overall activity levels.

The study also found that participants who received personalized feedback on their fitness tracker data were more likely to meet the recommended daily step counts. This suggests that providing additional support and motivation, such as personalized feedback or group exercise classes, may be helpful in encouraging older adults to increase their physical activity levels.

“Our study suggests that it may be more effective to encourage older adults to exercise individually or in group settings where they can receive personalized feedback and support,” said Dr. Grace Mok, lead author of the study from NTU’s Wee Kim Wee School of Communication and Information. “While exercising with a spouse can be enjoyable and motivating, it’s important to consider individual preferences and goals when designing exercise programs for older adults.”

The researchers recommend that future studies explore the factors that contribute to higher physical activity levels in older adults, both when exercising with a spouse and independently. They also suggest that exercise programs for older adults should be tailored to meet individual needs and preferences, and that personalized feedback and support should be provided to encourage long-term adherence.
