| Purpose:Cluster training is a new type of resistance training developed in recent years.In this study,we compare the effects of 8 week cluster training(CT)and traditional training(TT)on the muscle hypertrophy effect of young fitness enthusiasts,and try to explore the pros and cons of this new type of resistance training method.This study aim to provide theoretical and practical guidance for the development of specific resistance training exercise prescriptions in the future.Method: The study selected 24 male fitness enthusiasts,all of whom had more than 2 years of strength training and were proficient in squat movements.The subjects were divided into two groups: 12 in the traditional group(age 23.33 ± 1.07);12 in the cluster training group(age 23.67 ± 0.89).Test index: Changes in 1RM values and thigh muscle dimensions after 8 weeks of intervention.The effects of the two training methods on the kinetic indicators during the squat test,and the fatigue level index after completing the two trainings.The difference in blood lactate values after completion of both trainings.Result:(1)1RM had an interaction between the two groups before and after intervention(P<0.001).After the test,1RM was significantly greater in the CT group than before the intervention(P<0.001),and 1RM was significantly greater in the TT group than before the intervention(P<0.001).There was no significant difference in 1RM between CT group and TT group after 8 weeks of intervention(P=0.397).(2)Dimensions had interactions between the two groups before and after intervention(P<0.001).After the separate test,the dimensions of the CT group were significantly larger than those before the intervention(P<0.001).The post-intervention dimension of the TT group was significantly larger than that before the intervention(P< 0.001).There was no significant difference between the CT group and the TT group after eight weeks of intervention(P=0.302).(3)The kinetics of CT group and TT group(marked peak force,average speed,peak velocity,peak power,average power)were significantly greater than those before intervention(P<0.05).After eight weeks of intervention,the kinetics of the CT group and the TT group(nominal peak force,average velocity,peak velocity,peak power,average power)were not significantly different(P>0.05).(4)The RPE value had an interaction between the two groups and before and after training(P=0.018).After the test alone,the RPE of the CT group was significantly smaller than that of the TT group after eight weeks of intervention(P=0.003).The RPE intervention in the CT group and the TT group was significantly lower than that before the intervention,CT group(P=0.007)and TT group(P<0.001).(5)There was no interaction between blood lactate in the two groups before and after training(P=0.244).The blood lactate level after CT and TT intervention was significantly lower than before intervention(P=0.012).After eight weeks of intervention,the blood lactate level of the CT group was significantly lower than that of the CT group(P=0.011).Conclusion:(1)CT can complete more repetitive times(RIR)with higher quality in the case of lower fatigue.Compared with TT,it can help strength training for those with weaker muscles.(2)Both CT and TT can effectively increase the maximum strength of the squat;however,in this respect,CT does not have a greater advantage than TT.(3)Both CT and TT can effectively stimulate muscle hypertrophy and promote the growth of movement speed,power and peak force;however,it does not have a greater advantage than TT.CT can be used as an option for muscle hypertrophy training... |
