First time ever, a random controlled study has demonstrated how the timing of the day affects the effectiveness of physical activity. Based on the type of fitness and training objectives and the differences between women and men either in the morning or evening, exercise could be more advantageous. The multimodal week-long workout regimen described here nonetheless, improves fitness and health for all genders, regardless of timing of the day.
First time ever, scientists have demonstrated that the optimal time to exercise is dependent on the person’s sexual and training goals.
When should I incorporate my workout routine? In the majority of cases this decision is influenced by the schedule of our families and our work hours and perhaps even if have the status of “larks” as well as “night Owls.” But, in the past ten years, scientists have found that this question is more crucial than the limitations. This is due to new research that shows that the timing of the days (Exercise time Of Day, ETOD) could affect the effectiveness of exercise can be.
Research that is controlled and randomized suggests that ETOD affects the effectiveness of exercise, and further demonstrates that these effects differ in different exercise types and also between males and females. These findings were released in the journal Frontiers in Physiology.
Principal researcher Principal investigator Dr. Paul J Arciero, Professor of the Health and Human Physiological Sciences Department of Skidmore College in Saratoga Springs, NY, USA, stated: “Here we show for the first time women, exercising in the morning can reduce the belly’s fat content and increases blood pressure and evening exercise for women improves the upper body’s muscular strength endurance, power, and strength and boosts general mood and satiation with food.”
“We also have evidence that shows that, for males evening exercise reduces blood pressure, the chance of heart disease and feelings of fatigue. It also reduces fat more than as compared to exercising in the morning.”
New 12-week-long ‘multimodal’ training program
Researchers enlisted the aid of 26 males. All were age of 25 to 55, active, physically fit, non-smokers and with normal weight. They were instructed by coaches over 12 weeks following the RISE program that was originally developed by Arciero and colleagues. The program consisted of either 60 minutes in resistance (R) training sprint interval (I) training and stretch (S) training or endurance (E) training, based upon the time of week. Rest days were Wednesdaysand Saturdays and Sundays. The participants adhered to a carefully designed diet that contained 1.1-1.8g proteins per kilogram daily body weight.
The most important thing to note is that male and female subjects were assigned randomly to two options: only early morning workout (60 minute intervals between 06:30 to 0830) as well as evening exercise (between 18:00 until 20:00). The morning exercise participants had breakfast right after exercising and then three meals in four-hour intervals. For those who were assigned to exercise at night, they consumed three meals at four hour intervals prior to training and then another meal after.
At the beginning and at the close of the trial participants were assessed thoroughly for aerobic power as well as their muscular endurance and agility in balance, lower and upper muscle strength, power as well as their jumping abilities. Only 16% of 56 participants who took part were unable to finish duration of 12 week trial solely due to their inability to follow the nutrition and exercise regimen.
Apart from changes in the participants’ metabolic and physical parameters like blood pressure arterial stiffness, respiratory exchange ratio and the distribution of their bodies and the percent of fat during the course of the study, researchers also monitored changes in blood biomarkers that are relevant to the trial such as insulin, total and “good” HDL cholesterol C-reactive protein, as well as the IL-6. They also gave questionnaires to participants to gauge changes in mood , and the feeling of satiety from food.
Benefits that are clear from the program
The study’s findings show that the participants all improved in general performance and health over throughout the test regardless of their commitment to exercise in the morning or at night.
“Our study clearly shows the benefits of the evening and morning multimodal (RISE) exercise for improving the health of your mood and cardiometabolic system, and physical performance outcomes for men and women,” said Arciero.
They also demonstrate that ETOD is the determinant of the improvements in physical performance as well as cardiovascular health, body composition and mood.
In the example above the female participants all reduced the body’s total fat as well as hip and abdominal fat as well as blood pressure during the course of the study, however these gains were higher for women who exercised in the morning. The men who exercised in the evenings had a reduction in the percentage of HDL to total HDL cholesterol and blood pressure, as well as respiratory exchange ratio and carbohydrate oxidation. This was because fat became their preferred fuel source.
Different ETOD recommendations for women as well as men.
“Based on our research that women who want to reduce the belly’s fat content and blood pressure and at the same time improving leg muscle strength should exercise early in the day. If they are seeking to increase upper body strength and endurance and also improving their mood overall and eating habits and mood, exercise in the evening is the most effective option,” said Arciero.
“Conversely exercising in the evening is great for men who are who are interested in improving their heart health and metabolic health as well as improving emotional health.”
Author 2 Stephen J Ives, an associate professor at Skidmore College concluded: “We have proven that ETOD is an important aspect for everyone, both men and women due to its impact on the physical results of exercise. However, regardless of ETOD the importance of regular exercise, it is vital to our overall health.”
