One simple improvement that can enhance your exercise regime is committing to doing the same activity at the same time each day. According to a new study conducted on mice by the University of Manchester in the UK, there are several benefits associated with maintaining a regular exercise rhythm. The research suggests that while we have a central body clock in the brain known as the suprachiasmatic nucleus (SCN), we also have other localized body clocks. Interestingly, exercise has the ability to reset these local body clocks in our joints and spine. The study reveals that if this reset occurs at the same time every day, these local clocks can better align with the SCN clock, resulting in improved synchronization. Previous research has shown that when the clocks in peripheral tissues are out of sync, it can increase the risk of health issues such as diabetes and cardiovascular disease. Therefore, understanding the impact of regular exercise rhythms can have far-reaching implications for our overall health and well-being.
The findings of the study shed light on the interplay between exercise, the body clock, and the skeletal system. Qing-Jun Meng, a chronobiologist at the University of Manchester, explains, “Our results showed that physical activities in the morning, associated with daily patterns of sleep/wake cycle, convey timing information from the light-sensitive central clock in the brain to the weight-bearing skeletal tissues.” Essentially, exercise acts as a signal to our skeletal system, informing it that it’s time to wake up.
To conduct the study, researchers used a genetic reporting technique to monitor the clocks in the cartilage (joints), intervertebral discs (spine), and brains of transgenic mice as they exercised on treadmills at different times. Additionally, samples of cartilage tissue taken from the mice were studied to understand the osmotic responses. These areas are known to be particularly involved in exercise, and throughout the day, water is pressed out of them, causing us to become slightly shorter. This process of osmolarity helps to reset the localized body clocks on a daily basis. The research team discovered that exercise not only contributed to this osmolarity process but also further reset these clocks. Importantly, for maximum benefits, exercise should be performed on a consistent schedule. This regularity improves the timing links between the clocks in the body, leading to enhanced synchronization. Although these results need to be replicated in human studies, it is likely that similar effects are at play in our bodies.
Implications for Bone and Joint Health
The health of our bones and joints has a significant impact on various aspects of our lives, including our sports performance and susceptibility to injuries or conditions like arthritis. The study suggests that athletes traveling through different time zones may experience increased risk due to the disruption of their body clocks. Additionally, the researchers observed the same clock synchronization in older animals. This finding indicates that even for individuals in later stages of life who engage in moderate activities like brisk walking, maintaining a consistent exercise routine can still be beneficial.
The study conducted by the University of Manchester highlights the advantages of adhering to a regular exercise rhythm. By exercising at the same time each day, we can reset the local body clocks in our joints and spine. This synchronization with the central body clock in our brain promotes better overall health and reduces the risk of various diseases. While further research is needed to confirm these findings in humans, the potential benefits of consistent exercise habits are undeniable. So, if you’re looking to optimize your exercise routine, try incorporating a regular exercise rhythm into your daily life.
