not sure they link to the actual study but they claim statistical significance in the qigong intervention group giving performance gains (not sure of the metrics). maybe the study can be found separately.
Using three teams as our participants, we took volunteers who would be willing to wake up early Monday through Friday for a 6:00am Qigong recharge for eight weeks. Both intervention and control groups were given the exact same GPP weight-training program. The loads were determined by obtaining maximals prior to onset of the study (front squat, bench press, deadlift, and vertical jump) and loads were assigned to everyone using the exact same percentages throughout the program.
73 participants completed the eight weeks and we were able to find statistical significance across the board in favor of the Qigong intervention. Some of the numbers produced by the individuals from the Qigong group were so staggering I would not have believed it had I not seen it with my own eyes. We’re talking PED type numbers.
