Neural
Training muscle groups 1 day per week vs. 2 days per week does not result in significant differences in maximal strength, muscle thickness, or muscle endurance in trained men after 8 weeks.
Both training frequencies can be effective for neuromuscular adaptations.
StrongRefutesmedium confidence
No significant difference between conditions for maximal strength in the back squat or bench press, muscle thickness in the elbow extensors, elbow flexors, or quadriceps femoris, and muscle endurance in the back squat and bench press performed at 60% 1 repetition maximum was detected.
