ABSTRACT

One of the most widely used Olympic weightlifting derivatives, hang snatch and clean, is believed to be one of the most effective ways to improve the performance of athletes in sports that require power, strength, and speed. This study was conducted to investigate the effects of split-style hang snatch, and clean and jerk training (twice a week for 6 wk) on leg stiffness, vertical jump, agility, and sprint performance in volleyball players. The participants (n=34 collegiate female volleyball players) were randomized into training (n=17, age=15.63±1.3 years, height=166.05±5.7 cm, body weight=63.45±2.97 kg) and control groups (n=17, age=15.23±1.83 years, height=167.46±5.69 cm, body weight=60.46±4.14 kg). The variables included spike jump, counter movement jump, time to 5-m sprint and 20-m sprint, change of direction, and leg stiffness. The effects of split-style hang snatch and clean and jerk training on the measured variables were assessed by magnitude-based inferences. Generally, the increases in the measured variables were higher in the training group. The probability of an increase in leg stiffness was very likely (precision, 98.9%, d=0.722); 5-m sprint increase very likely (99.7%, d=−1.544); 20-m sprint increase very likely (99.9%, d=−0.774); and the probability of increase in change of direction was found to be likely, (85.4%, d=−0.385). The increases in countermovement jump were insignificant. We conclude that split hang snatch and clean and jerk exercises improve leg stiffness, spike jump, time to 5-m and 20-m sprint, and change of direction in female volleyball players.
