Maintaining a consistent routine of physical exercise stands as one of the most vital actions any individual can take to safeguard their long-term health and vitality. Despite the well-documented benefits of staying active, a staggering number of people across the globe are failing to meet even the most basic movement requirements. Current global statistics paint a concerning picture of a sedentary society: approximately one in three adults do not meet the minimum recommended levels of physical activity. The situation is even more dire for the younger generation, as four out of every five children between the ages of 11 and 17 fall short of the recommended average of 60 minutes of moderate-to-vigorous activity per day. This widespread inactivity is not merely a matter of fitness; it is a burgeoning public health crisis.
The consequences of a sedentary lifestyle are far-reaching and profound. A chronic lack of physical movement significantly elevates the risk of developing debilitating long-term health conditions, most notably type 2 diabetes and various cardiovascular issues. However, the impact extends beyond physical ailments to the very way our brains function. Inactivity can negatively affect cognitive function—the essential mental processes that allow us to learn new information, retain memories, maintain concentration, and make informed decisions. For children, these cognitive skills are the bedrock of development; they are inextricably linked to educational achievement, school performance, and the breadth of opportunities available to them in their future professional lives.
For many, the transition into parenthood presents a unique set of challenges that can derail even the most committed fitness enthusiasts. Parents often find it exceptionally difficult to remain active while balancing the relentless demands of modern family life. The “time poverty” associated with raising children—juggling work, chores, and childcare—frequently leaves little to no room for personal exercise. Research suggests that the milestone of becoming a parent often leads to a measurable decline in moderate-to-vigorous physical activity. Because physical inactivity is a behavior that tends to affect both generations simultaneously, families have become a critical focal point for health interventions. By targeting the family unit as a whole, researchers hope to improve the collective health and wellbeing of both parents and their children.
Exploring obstacles and sources of inspiration
In our pursuit to understand these dynamics more deeply, we recently conducted a qualitative research study involving interviews with 24 different families. Our goal was to explore the specific factors that either help or hinder a family’s ability to stay active and to see if these experiences varied based on a family’s socioeconomic background.
Many of the barriers we uncovered were expected, yet they remain significant hurdles for many households. Families frequently pointed to the high cost of organized sports and extracurricular activities as a major deterrent. Furthermore, a general lack of free time was cited as a primary obstacle preventing families from engaging in active play together. However, we did notice a divide based on economic standing. Families from less affluent backgrounds often described a frustrating lack of access to local sports and leisure facilities, whereas families from more affluent backgrounds tended to view their local infrastructure as a vital support system that helped them maintain their active lifestyles.
One of the most heartening findings of our interviews was the power of mutual inspiration within the home. Children consistently reported that seeing their parents being active served as a powerful motivator for them to join in and move their bodies. Interestingly, this influence was not a one-way street. Parents, particularly those from less affluent backgrounds, often described their children as their primary role models for health. They explained that their children’s natural enthusiasm for movement and play acted as a catalyst, motivating the adults to overcome their own lethargy and become more active themselves.
These insights suggest that physical activity within a household is not just a top-down instruction from parent to child. Instead, it is a reciprocal relationship where family members can inspire one another, fostering positive, lifelong habits that benefit the entire family ecosystem.
Putting theory into practice:The tag rugby programme
Building upon the findings from our interviews, we developed a specialized, family-based physical activity program. The goal was to create a framework that allowed parents and children to exercise side-by-side in a way that felt like play rather than a chore. We specifically chose tag rugby as the core activity for this intervention. We selected this sport because it is inherently fun, highly adaptable to different skill levels, and, crucially, non-contact. These features make it an ideal inclusive activity where people of vastly different ages and physical abilities can participate safely and effectively together.
Once the program was established, we sought to determine if even a brief intervention could yield measurable results. We designed a study to see if a single 45-minute session of family tag rugby could produce immediate, short-term benefits for both physical health and cognitive performance.
Measuring benefits to brain, body
Sixteen families volunteered to participate in this specific phase of the study. The experiment was designed with two distinct scenarios for comparison. On one occasion, the families took part in a 45-minute tag-rugby session, which included a structured warm-up, various skill-building activities, and small-sided games. On a separate occasion, the same families participated in a control session that involved 45 minutes of seated rest, providing a baselinefor comparison.
To gauge the impact on the brain, participants completed a series of computer-based tasks both before and after each session. These tasks were specifically designed to assess various aspects of cognitive function, such as working memory, sustained attention, and the speed of information processing. To gauge the impact on the body, we monitored how the participants responded to a standardised lunch provided after the sessions. By tracking their blood-sugar and insulin levels, we could see how their metabolism reacted to the physical exertion.
Insulin is a vital hormone responsible for helping the body regulate blood sugar levels. Our findings regarding the parents were particularly striking. Following the tag-rugby session, parents exhibited significantly lower insulin concentrations after eating their meal compared to their levels after the resting session. What makes this finding remarkable is that their blood-sugar levels remained similar in both scenarios. This indicates that after just 45 minutes of exercise, the parents’ bodies became more efficient, managing their blood sugar effectively while requiring less insulin to do so.
The cognitive results were equally encouraging. We observed immediate short-term improvements in mental performance across both generations. Children showed a marked improvement in working-memory tasks right after the exercise session. Meanwhile, parents demonstrated enhanced information-processing skills immediately following the game, with these cognitive benefits persisting for up to 45 minutes after the activity had ended.
A starting point for future health
While these results are exciting, it is important to interpret them with a degree of caution. Our study focused on a relatively small group of 16 families and measured the physiological and mental effects of only a single bout of exercise. Because of this, we cannot yet say for certain whether these benefits would persist over the long term or if they would accumulate into even greater health gains if a family participated in such activities on a regular, weekly basis.
Nevertheless, these findings serve as a highly promising starting point for future research and public health policy. Whether we are a child learning in a classroom, an adult concentrating on complex tasks at work, or a parent managing the chaotic logistics of everyday family life, we rely heavily on our memory, attention, and information-processing abilities throughout the day. A form of exercise that families can enjoy together is inherently more sustainable than traditional exercise routines that place extra demands on the schedules of already overstretched parents.
Ultimately, our research suggests that family-based physical activity offers a practical, dual-purpose solution. It supports physical health and sharpens cognitive performance while simultaneously providing a rare opportunity for parents and children to bond through shared, enjoyable experiences. In a modern world where both adults and children are struggling to move enough, creating accessible, fun, and inclusive opportunities for families to get active together is a strategy that deserves much greater attention and investment.
