Mechanical torsion

Based on the research provided, which of the following can be inferred about hypertrophy training?

The research conclusively supports hypertrophy at lower intensities

The research conclusively refutes hypertrophy at lower intensities

The research somewhat supports hypertrophy at lower intensities, but more research is recommended

When considering strict intensity cutoffs for hypertrophy training, such as the one provided by the American College of Sports Medicine at 65% of 1RM, what consideration is neglected?

The volume (number of sets) is not considered

The frequency (sessions per week) is not considered

The time (length of session) is not considered

Based on the studies presented, which of the following is a common way to evaluate hypertrophy in research?

Ultrasound imaging

Skinfold measurement

Bioelectrical impedance analysis

According to the research, what amount of effort is most likely required to achieve muscle hypertrophy?

At least half of the maximal number of repetitions for a given intensity

At least 75% of the maximal number of repetitions for a given intensity

Near the maximal number of repetitions for a given intensity

Which population may benefit the most from the ability to increase hypertrophy at the lower intensity ranges?

Athletes with 5 years training experience

Untrained adults

Older individuals

While hypertrophy may occur at low intensities, what quality will likely not increase?

Strength

Neuromuscular adaptation

Exercise technique

Which of the following is likely true considering all of the research presented in this article?

Hypertrophy is unlikely to occur if the intensity is below 80% of one-repetition maximum (1RM)

Hypertrophy may occur at intensities from 30 – 90% of 1RM if volume is equalized

Hypertrophy may occur at intensities from 30 – 90% of 1RM even if volume is not equalized
