Strength or Endurance Training - Which is Better?
It's probably the oldest debate in the fitness world: Should you lift weights or rack up miles on the pavement? While two opposing camps used to face each other, modern sports science today presents a much more nuanced picture. Both forms of training have their justification, but they affect your body in completely different ways.
The Molecular Switches: mTOR vs. AMPK
At the cellular level, strength and endurance training activate different signaling pathways. It's important to understand this to design your own training effectively:
- Strength Training (mTOR): Primarily affects muscles. Mechanical stress activates the mTOR signaling pathway, which stimulates protein synthesis and promotes muscle growth.
- Endurance Training (AMPK): Primarily focuses on energetic efficiency. The AMPK signaling pathway is activated, promoting the formation of new mitochondria (the powerhouses of the cells) and strengthening the cardiovascular system.
Studies show that both forms lower blood pressure and improve blood values. While endurance training more effectively lowers resting heart rate, strength training increases basal metabolic rate – meaning you burn more calories even when you're not doing anything.
Fat Loss and Weight Management
Those who want to lose weight often face the choice: cardio or iron? Science (including Lehri & Mokha, 2006) shows that endurance training often leads to higher direct body fat loss. Strength training, on the other hand, is unbeatable when it comes to protecting valuable lean mass (muscles) during a diet. A combination of both seems most sensible for body composition.
The Pareto Decision: What is more efficient?
If time is a scarce factor, strength training often wins according to the Pareto principle. Why? Because strong muscles are the foundation for a functioning daily life – they support joints, prevent back pain, and keep the metabolism active. Nevertheless, the best sport is the one you can stick with long-term and that brings you joy.
Strength training builds, endurance training optimizes. For maximum health, a mix is ideal – but if you have to choose: Get strong first, then enduring!
