Many studies in the past have come to the conclusion that regular exercise improves cardiovascular help but a new study suggests that the time of day at which the exercise takes place may cause variable results.

The study was conducted by researchers from the Joslin Diabetes Center and Brigham and Women’s Hospital. The findings which were published in the Diabetes Care journal suggests that the time of day that obesity or diabetes patients engage in moderate to vigorous fitness activities may determine the level of cardiovascular fitness.

The study had 2,035 people participants and the investigators observed that the men who exercised in the morning were more likely to suffer from coronary heart disease (CHD) than those who worked out at different times in the day. They also discovered that men with higher physical activity at around midday achieved lower cardiovascular fitness. The researchers did not observe any correlation between CHD timing and fitness activity timing in Women.

The research dubbed Look AHEAD study involved tracking study participants through accelerometers mounted on their hips. Investigators kept track of the time of day at which the exercise took place with a focus on moderate to intense physical activity that includes labor-intensive work. Researchers believe that gender-specific physiological processes explain the differences observed in men particularly based on the time of day that physical activity takes place.

The study findings could be useful in fitness optimization

Investigators also acknowledge that there could be other factors influencing the study results. One of the theories is that the circadian system might also have an influence on the outcomes. Nevertheless the observation that the time of day affects the effectiveness of fitness in preventing cardiovascular events in diabetics is significant. The information can be used to tweak physical activities especially fitness for people with diabetes so they can optimize their cardiovascular health.

A diabetes patient’s goal is to achieve optimal management of their health condition. Since they are prone to cardiovascular attacks, it only makes sense to customize their fitness activities by working out during the time of day that allows them to reduce the risk of occurrence of cardiovascular events.
