Recent studies have brought to light some fascinating insights into the nuances of muscle building and strength training.
A study from Florida Atlantic University, recently highlighted on ScienceDaily, delves into the importance of training close to muscle failure for hypertrophy while suggesting a different approach for strength gains.
This research has crucial implications for both seasoned athletes and fitness enthusiasts who are looking to maximize their workout results.
Let me break down these findings and explore what they mean for your fitness routine.
Understanding Muscle Hypertrophy vs. Strength Gains
Muscle Hypertrophy refers to the increase in muscle size, a primary goal for bodybuilders and anyone looking to enhance their muscular physique.
Hypertrophy occurs when muscle fibers grow in response to resistance training, particularly when the muscles are pushed to near failure, creating microscopic tears that repair stronger and larger.
On the other hand, Strength Training focuses on increasing the maximum force a muscle or muscle group can exert.
It often involves lifting heavier weights with fewer repetitions and longer rest periods, emphasizing the efficiency of movement rather than the volume of work.
The Importance of Training Close to Failure
The study titled “For Bigger Muscles, Push Close to Failure, For Strength, Maybe Not” suggests that muscle hypertrophy is best achieved when workouts are performed near muscle failure.
This means that performing a set of an exercise to the point where only 0-5 repetitions could be completed before failure is ideal for stimulating muscle growth.
Why is This Effective?
Training close to failure ensures that a maximum number of muscle fibers are recruited and fatigued.
This approach stresses the muscles enough to trigger hypertrophy, but without the risk of overtraining or injury that can come with consistently training to absolute failure.
Why Strength Gains Are Different
While training to near failure is beneficial for hypertrophy, the study indicates it’s not as crucial for strength gains.
For strength, the focus is on the quality of the movement and lifting heavy weights with proper form.
Training to failure too often can lead to form breakdown and increased injury risk, which can be counterproductive for strength training.
Balancing the Two Goals
For those looking to build both muscle size and strength, it is essential to understand when to push to failure and when to hold back.
The research suggests incorporating periods of high-intensity training close to failure for hypertrophy-focused phases and then shifting to lower intensity, high-weight training for strength phases.
Repetition Tempo: A Key Factor in Muscle Growth
Another crucial finding from the study is the impact of repetition tempo on muscle growth.
Repetition tempo refers to the speed at which a repetition of an exercise is performed and is usually broken down into four phases: eccentric (lowering the weight), pause at the bottom, concentric (lifting the weight), and pause at the top.
Ideal Tempo for Hypertrophy
For hypertrophy, the study suggests a controlled tempo where the eccentric phase (lowering the weight) is slower, lasting about four seconds.
This phase should be followed by a one-second pause, a one-second concentric lift, and no pause at the top.
This 4-1-1-0 tempo ensures that the target muscles are under tension for a sufficient amount of time, maximizing the micro-damage necessary for muscle growth.
Why Slower is Better
Slowing down the eccentric phase of a lift increases the time under tension, which is a critical factor for muscle growth. It helps muscle hypertrophy.
This tempo also prevents the weight from being lowered by gravity, instead forcing the muscle to control the descent, which increases muscle fiber recruitment.
Exercise Selection: Long Muscle Lengths for Better Results
The study also emphasizes training at long muscle lengths, which involves exercises that stretch the muscle to a greater degree.
For example, exercises like Romanian deadlifts or deep squats stretch the hamstrings and quadriceps more than standard versions, activating a more significant portion of the muscle fibers.
Why Does This Matter?
Exercises performed at long muscle lengths create a more significant stretch, which has been shown to activate more muscle fibers and lead to greater hypertrophy compared to exercises performed at shorter lengths.
This finding encourages a reevaluation of exercise selection, favoring movements that challenge the muscle through a more extensive range of motion.
Implementing the Findings in Your Training Routine
Based on the study’s findings, here’s how you can structure your workouts for optimal muscle growth and strength:
- For Hypertrophy:
-
- Rep Range: 6-12 reps, close to failure.
- Tempo: Use a 4-1-1-0 tempo for each rep.
- Frequency: Train each muscle group 2-3 times per week with 2-3 sets per exercise.
- Exercise Selection: Focus on movements that target the muscle at a long length, like Romanian deadlifts, deep squats, or overhead triceps extensions.
- For Strength:
-
- Rep Range: 3-5 reps, not necessarily to failure.
- Tempo: Use a controlled but quicker tempo, such as 2-0-1-0.
- Frequency: Train each muscle group 1-2 times per week with 3-5 sets per exercise.
- Exercise Selection: Choose compound lifts like bench press, squats, and deadlifts.
- Combining Both:
-
- Alternate between hypertrophy and strength phases in your training. For example, focus on hypertrophy for 4-6 weeks, then shift to a strength phase for the next 4-6 weeks.
Conclusion
The recent study from Florida Atlantic University provides valuable insights into optimizing training for muscle hypertrophy and strength gains.
By understanding the importance of training close to failure for muscle growth and adapting repetition tempo and exercise selection, you can create a more effective training plan. Most importantly, you need to stick with a healthy diet plan for enhanced muscle growth and strength development.
These findings are particularly beneficial for those who want to balance building muscle size and increasing strength without compromising on either.
