Brief 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.

Outcome Measures

Primary Outcomes (8)

  • 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

  • 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

  • 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

  • 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

  • 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

  • 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

  • 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

  • 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

Study Arms (2)

Plyometric training

EXPERIMENTAL

The 8 weeks of plyometric training 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.

Other: Plyometric training

Routine training

ACTIVE COMPARATOR

During the intervention, the control group just continued with their routine training regime (e.g., normal fitness training, and injury prevention drills), twice a week, for the duration of the experiment.

Other: Routine training

Interventions

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

Plyometric training

Regular tennis training, including normal fitness training, and injury prevention drills

Routine training
