EXERT-BCHC: Prospective Study of EXErcise Regimens After Treatment for Breast Cancer for Hypertrophy and Conditioning

Summary

This study investigates the impact of four standard of care, monitored group exercise regimens (resistance training) on conditioning and hypertrophy in women previously treated for breast cancer. The study will compare two conditioning regimens (6-12-25 and 8x8) and two hypertrophy regimens (5/5/5 cluster sets and double training) to assess changes in VO2 max, muscle mass, and fat mass.

Interventions

• Other
  6-12-25 Training Regimen

  A conditioning regimen involving three exercises performed consecutively with minimal rest. Includes 4-6 repetitions at 4-0-1-0 tempo, 10-12 repetitions at 3-0-1-0 tempo, and 20-25 repetitions at 2-0-1-0 tempo.

• Other
  8x8 Training Regimen

  A conditioning regimen optimizing high volume with short rest periods. Six exercises are performed consecutively with a 2-0-1-0 tempo and no rest between sets.

• Other
  5/5/5 Cluster Set Training Regimen

  A hypertrophy regimen where an individual performs 5 repetitions at a tempo of 4 seconds during the eccentric movement of the exercise, while performing the concentric motion in 1 second then resting for 20 seconds and repeating the sequence two additional times to total three clusters of 5 repetitions.

• Other
  Double Training Regimen

  A hypertrophy regimen adding an additional set of lesser repetitions for a specified exercise at the end of a tri-set of exercises.
