Method: 50 healthy males with at least 1-year resistance training experience were recruited, the experiment was conducted with a counter-balanced design. Prior to the experiment, the participants performed 4 types of gripping in order to get familiar with required movements, the experiment was then carried out after 2 days of recovery. The test movements included: normal grip, grip with opposite hand making a fist, grip with deep breath and resistance expiration, grip with opposite hand making a fist and deep breath and resistance expiration. Every movement was repeated for 3 times, and the participants should grip with maximum effort for 5 seconds, the resting time between every grip was 1 minute, and there was 3 minutes of resting between every cycle, total experiment time was 18 minutes. Repeated- measures one-way ANOVA was applied to compare the effect of different types of movement on maximum grip strength. Result: The grip strength of the maximum grip performance force in four movements shows an upward trend, but all of them are higher than normal grip strength （46.73 ± 6.40 kg vs. 47.51 ± 6.39 kg vs. 48.41 ± 6.19 kg vs. 49.58±6.49 kg）. If normal grip strength was deemed as reference value and the rate of change was calculated, then the value of grip with opposite hand making a fist and deep breath and resistance expiration was significantly greater （6.35 ± 5.99,p < .05）. Conclusion: After using different movement types and breathing modes to test maximum strength, the one single movement changes effect maximum grip strength progress of magnitude smaller, yet if two or more different movements were activated simultaneously, it could still increase maximum grip strength performance. If you want to use the Contralateral hand, deep breath or Resistance expiration , and Contralateral hand or Resistance expiration action modes to enhance your sports by instantly boosting your explosiveness.
