Minimal dose resistance exercise strategies, like the "Weekend Warrior" approach, can improve muscle strength for individuals lacking time. Even small amounts of exercise are better than none for building strength.
Area of Science:
- Exercise Physiology
- Public Health
Background:
- Many individuals avoid resistance exercise due to time constraints.
- Minimal dose strategies offer a potential solution by reducing exercise volume.
- The effectiveness of these minimal dose strategies on muscle strength requires clarification.
Purpose of the Study:
- Define and characterize minimal dose resistance exercise strategies.
- Summarize the effects of these strategies on muscle strength.
- Target individuals not currently participating in resistance exercise.
Main Methods:
- Overview of minimal dose resistance exercise strategies: 'Weekend Warrior,' single-set, resistance exercise 'snacking,' strength test practice, and eccentric minimal doses.
- Characterization based on frequency, set number, session duration, exercise number, repetition number, and concentric/eccentric muscle actions.
- Synthesis of existing research on their impact on muscle strength.
Main Results:
- All reviewed minimal dose strategies demonstrated an increase in muscle strength.
- 'Weekend Warrior' and single-set resistance exercise show strong research support.
- Resistance exercise 'snacking' and eccentric minimal doses are emerging concepts with promising outcomes.
Conclusions:
- Minimal dose resistance exercise strategies effectively improve muscle strength.
- 'Weekend Warrior' and single-set approaches are well-supported.
- Public health initiatives can promote low-volume resistance exercise as beneficial compared to inactivity.

Exercise and Muscle Performance
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
