                            BFR combined with RT:
                               Improvements in hypertrophy
                               Improvements in muscular strength (but

                               likely superior for strength gains)

     Aerorbic Training:
        Improvements in strength/muscle size
        Possible improvements in Vo2max and
        sports performance
     Post-injury:
        Improved pain scores compared to high
        load resistance training.
        Improved strength compared to low load
