Growth hormone release is affected by the type of resistance training protocol used, including the duration of rest periods. Short rest period types of workouts result in greater serum concentrations compared to long rest protocols of similar total work; however, at present it is not clear how the various molecular forms or types of growth hormones are affected by rest period duration.
Field tests have become popular in applied exercise science and sport performance enhancement programs because of their simplicity and ability to generalize results. However, numerous confounding factors may influence the validity of test data from such evaluations.
