Clinical Trial Summary

The main objective of this study is to examine the effects of upper and lower limb plyometric training on the selected physical fitness and serve performance among university female tennis players in China.

The main hypothesis of this study is to evaluate whether there are significant effects of 8 weeks of upper and lower limb plyometric training on selected physical fitness and serve performance among university female tennis players in China.

Description:

This intervention lasted for 8 weeks, two times each week, for 30-60 minutes of low-high intensity exercise. The content of the experimental group and control group of exercises mainly includes warm-up, primary content, and cool down. The intervention included push-ups and medicine ball exercises for the upper limbs and jumping, hopping exercises for the lower limbs. Exercises for the upper limbs were immediately followed by lower-limb exercises, with no intervening rest periods. all plyometric exercises, including those involving the upper and lower limbs, were executed with maximal effort, with the goal of reducing contact time during each repetition, and with no allowance for rest periods between jumps. During the intervention, the control group just continued with their regular training regime (e.g., normal fitness training, and injury prevention drills), twice a week, for the duration of the experiment.

Related Conditions & MeSH terms

• Physical Illness
• Skill, Coping

Intervention

Other:
• Plyometric training
Plyometric training can be described as a type of exercise that involves a rapid and forceful movement that consists of an eccentric contraction, followed by an immediate and explosive concentric contraction. Upper and lower limb plyometrics are exercises that enable an upper and lower body muscle group to react quickly to produce maximal strength
• Routine training
Regular tennis training, including normal fitness training, and injury prevention drills

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from baseline power performance at 4 weeks and 8 weeks	Power is the ability to perform strength based movements quickly.	Pretest: Before experiment; Mid-test: 4 weeks end; Post-test: 8 weeks end
Primary	Change from baseline strength performance at 4 weeks and 8 weeks	Strength is the maximal force or torque that a muscle can generate.	Pretest: Before experiment; Mid-test: 4 weeks end; Post-test: 8 weeks end
Primary	Change from baseline speed performance at 4 weeks and 8 weeks	The ability to move all or part of the body as quickly as possible	Pretest: Before experiment; Mid-test: 4 weeks end; Post-test: 8 weeks end
Primary	Change from baseline agility performance at 4 weeks and 8 weeks	Agility is a skill considered to be important for many sports and has been defined as "a rapid whole-body movement with change of velocity or direction in response to a stimulus.	Pretest: Before experiment; Mid-test: 4 weeks end; Post-test: 8 weeks end
Primary	Change from baseline endurance performance at 4 weeks and 8 weeks	Endurance describes your body's ability to maintain physical activity for an extended amount of time.	Pretest: Before experiment; Mid-test: 4 weeks end; Post-test: 8 weeks end
Primary	Change from baseline flexibility performance at 4 weeks and 8 weeks	Flexibility is the ability to move muscles and joints through a full normal range of motion.	Pretest: Before experiment; Mid-test: 4 weeks end; Post-test: 8 weeks end
Primary	Change from baseline serve velocity performance at 4 weeks and 8 weeks	It is one of the most repeated strokes during the game.	Pretest: Before experiment; Mid-test: 4 weeks end; Post-test: 8 weeks end
Primary	Change from baseline serve accuracy performance at 4 weeks and 8 weeks	In many sports, the accuracy of the execution of a motor skill determines success or failure.	Pretest: Before experiment; Mid-test: 4 weeks end; Post-test: 8 weeks end
