Similar Strength and Hypertrophic Adaptations in Less Time? Myo-Reps vs. Traditional Straight-Sets in Resistance-Trained Men.

Myo-reps produced a statistically significant reduction in session duration compared to traditional straight-sets.

• The acute crossover study used a sample of n=9 subjects who completed both protocols
• Session duration difference was statistically significant (p < 0.001)
• The exercises used for comparison were flat barbell bench press protocols
• No specific time values (in minutes) were reported in the abstract, only the statistical significance of the difference

Muscle excitation as measured by electromyography did not differ significantly between Myo-reps and traditional straight-sets in the acute study.

• EMG was used to measure muscle excitation during both protocols
• No statistically significant difference was found (p = 0.374)
• The acute study used a crossover design with n=9 subjects
• A linear positioning transducer was also used alongside EMG to assess mechanical output

Mean barbell velocity did not differ significantly between Myo-reps and traditional straight-sets in the acute study.

• Mean barbell velocity was measured using a linear positioning transducer
• No statistically significant difference was found (p = 0.766)
• Both muscle excitation and barbell velocity results suggest similar neuromuscular demands between the two protocols acutely
• The crossover design with n=9 subjects allowed within-subject comparisons

Both Myo-reps and traditional straight-sets groups showed statistically significant increases in muscle size over 8 weeks, with no significant difference between groups.

• The 8-week study involved n=22 subjects divided into two groups
• Both groups showed significant increases in muscle size (p < 0.001)
• No between-group differences were observed for muscle size
• Exercises performed were flat barbell bench press, incline barbell bench press, and seated cable fly, twice weekly

Both Myo-reps and traditional straight-sets groups showed statistically significant increases in strength over 8 weeks, with no significant difference between groups.

• Both groups showed significant increases in strength (p < 0.001)
• No between-group differences were observed for strength
• Strength endurance was also assessed as an outcome measure
• Participants were resistance-trained men

The Myo-reps group performed approximately 30% less volume load than the traditional straight-sets group over the 8-week intervention.

• The difference in volume load between groups was statistically significant (p = 0.001)
• The Myo-reps group performed 'approximately 30% less VL than the TRA group'
• Despite lower volume load, the Myo-reps group achieved similar muscle size and strength outcomes
• This finding supports the time-efficiency of the Myo-reps protocol

The study concluded that Myo-reps can be a viable option to achieve similar hypertrophic and strength results in less time compared to traditional straight-sets.

• No differences were observed between groups on muscle excitation, mean barbell velocity, muscle size, or strength
• Myo-reps achieved equivalent outcomes with significantly less session time and approximately 30% less volume load
• The authors stated: 'MYO can still be a viable option to achieve similar results in less time'
• The study design included both an acute crossover component (n=9) and an 8-week longitudinal component (n=22)
