Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Isometric and isotonic contractions are the same thing. | Isometric and isotonic contractions are two different types of muscle contractions. In isometric contraction, the muscle length remains constant while tension increases, whereas in isotonic contraction, the tension remains constant while muscle length changes. |
| Isotonic exercises are better for building strength than isometric exercises. | Both isometric and isotonic exercises can be effective for building strength depending on the specific goals of an individual’s training program. Isotonic exercises may be more beneficial for increasing muscular endurance, while isometric exercises may be more beneficial for improving static strength at a particular joint angle or position. |
| You can only perform isometric contractions with bodyweight exercises like planks or wall sits. | While bodyweight exercises like planks or wall sits are common examples of isometric exercise, it’s possible to perform isometrics with weights as well by holding a weight in a fixed position without moving it (e.g., holding a dumbbell halfway through a bicep curl). Similarly, many traditional resistance training movements involve both concentric (shortening) and eccentric (lengthening) phases that make them isotonic rather than purely static or dynamic movements. |
| Isotonic exercise involves lifting heavy weights only once per set. | Isotonic exercise refers to any movement where there’s consistent tension throughout the range of motion regardless of how much weight you’re using; this means that you could lift lighter weights multiple times per set and still engage in an isotonic workout if your muscles remain under load throughout each repetition. |
| Isometrics don’t burn calories because they don’t involve movement. | While it’s true that performing an isolated plank won’t burn as many calories as running several miles would due to differences in heart rate elevation and energy expenditure between aerobic vs. anaerobic exercise, isometric exercises can still be an effective way to build strength and improve overall fitness levels. |
