A recent study conducted by Edith Cowan University in Australia, in collaboration with institutions in Japan, has uncovered an efficient workout technique that requires only three seconds of exercise, repeated three times a week. This alternative approach (3-second workouts) to muscle strengthening challenges traditional beliefs by focusing on eccentric, muscle-lengthening exercises, which have shown to yield better results than concentric, muscle-shortening actions. While the study’s small scale calls for further exploration, its findings suggest that minimal yet consistent exercise can lead to impressive muscle strength gains.
THE STUDY’S APPROACH
The experiment involved 26 young, healthy adults divided into two groups. One group performed 3-second bicep extension workouts twice a week, while the other group engaged in the same exercises three times a week. After four weeks, the forces exerted by their elbow flexors and the muscle thickness of their biceps brachii and brachialis were measured and compared.
ECCENTRIC EXERCISES YIELD POSITIVE RESULTS
Results indicated that after just one minute of cumulative exercise over four weeks, participants who followed the eccentric training approach saw an 11.5% improvement in muscle strength. Notably, participants performing exercises that lengthened bicep muscles experienced better results than those engaging in movements that shortened them. This study builds upon previous research supporting the effectiveness of eccentric exercises for muscle conditioning.
FREQUENCY AND RECOVERY
The study suggests that the frequency of exercise may play a more significant role in achieving meaningful results than the duration of each exercise. Short 3-second workouts provide a substantial period of rest between exercises, allowing muscles to recover. This rest period, linked to a “silent period” in the motor cortex, could contribute to increased muscle strength. The study implies that working out at least three times a week, even for just a few seconds, is necessary to observe noticeable benefits.
While these 3-second workouts may not enhance cardiovascular fitness, they offer a promising route to improved muscle strength. By prioritizing eccentric exercises and emphasizing consistent yet short routines, individuals can efficiently boost their muscle conditioning. Although more research is required to fully understand the mechanisms at play, this study highlights the potential of brief yet frequent workouts to make a meaningful impact on physical well-being.
