Anaerobic lactic: This system provides energy for activities lasting up to a minute. Aerobic: This system provides energy for longer bouts of activity by breaking down carbs, amino acids, and fatty acids. It requires oxygen and can create lactic acid depending on the intensity. And in order to tap into and train each while maintaining the most muscle possible, you need a different approach, or stimuli, which means proper work, rest protocols, and volume, Holder says.
If you want to hang on to as much muscle as possible, do two workouts a week—max three. You can work your aerobic energy system and still increase your muscle, but you need to work at the right intensities. Your body will drop muscle with constant low-intensity exercise to optimize your size for the task at hand a.
Start with a minute jog at 5 miles per hour. Then, do a second sprint at 7. Return to the jog for 90 seconds. Repeat this cycle as often as you can, and try to do more cycles each week.
Completing this routine for 30 minutes three times a week will yield the best results. More evidence about the anabolic power of running comes from studies on muscle-wasting. Extended bed rest causes your muscles to break down. For example, a report in the journal Diabetes showed that healthy adults lost more than 3 pounds of muscle mass in a single week of bed rest.
A similar problem happens during space travel. The lack of impact loading in space causes muscle loss in astronauts. These changes occur even when the astronauts do conventional forms of exercise.
However, running on a space treadmill can attenuate these losses. However, there's some truth to the idea that running can take away your muscles. Olympic distance runners, for example, have very little muscle and fat. That's because long-distance running breaks down muscle instead of building it. A report in Medicine and Science in Sports and Exercise showed this robust effect in ultra-marathoner runners. In this study, middle-aged men had their skeletal muscle mass measured before and after a mile race.
Results indicated that they lost more than 2 pounds of muscle mass during this race. This loss of muscle mass has many negative consequences.
For example, having a greater muscle mass in your lower body protects your bones , meaning that losing muscle can increase injury risk , according to a article in the International Journal of Sport and Exercise Psychology. The good news is that you might be able to stop this muscle loss by making wise dietary choices.
A paper in the Journal of the American College of Nutrition showed that the daily intake of a beef protein beverage for 10 weeks prevented muscle wasting in master triathlon athletes. Running can positively affect your health in other ways as well. In a review published in Sports Medicine , researchers noted that running enhances aerobic capacity, increases muscle mass, promotes good cholesterol and decreases body fat in people with a sedentary lifestyle.
These results typically follow a dose-response curve , with more running leading to greater benefits. Road racing offers an easy way to improve your health.
