Abstract: Objective: To investigate the effects and physiology mechanism of rest-redistribution and traditional sets by measuring kinetic performance during eccentric training. Method: 11 healthy male volunteers perfumed rest-redistribution training and traditional training on two inconsecutive weeks' Monday. For each protocol, participants performed 40 repetitions with 285 s of total rest, respectively, traditional sets had 4 sets of ten repetitions with 95 s inter-set rest and rest-redistribution sets had 20 sets of 2 repetitions with 15 s inter-set rest. Peak torque and total work were measured to evaluate kinetic performance, meanwhile tissue oximetry was assessed throughout each protocol to detect local circulation and oxygen consumption. RPE was inquired during and after the training. Excel and Graphpad Prism 5 were used to unscrambling data after experiment followed by data analysis with SPSS and JASP. Result: Rest-redistribution sets maintained force development ability during eccentric training (P<0.05) with significantly decline of tissue saturation (P<0.05), whereas no significant difference in total work (P>0.05), total hemoglobin concentration (P>0.05) or RPE (P>0.05) compare to traditional sets. Conclusion: Rest-redistribution contributed to maintenance of kinetic performance during high intensity eccentric training and increase of exercise load, oxygen consumption and training stimulation.
