NCT06412809

Brief Summary

Given conflicting studies regarding the effect of land-based and water-based training on the jump performance of volleyball and basketball players, a randomized controlled trial is conducted. This study hypothesizes that combined land- and water-based core and lower strength training significantly increase jump performance of volleyball and basketball players in comparison to either land- and/or water-based training alone.

Study Arms (3)

Combined Land- and Water-Based Exercise

EXPERIMENTAL

Core and lower extremity strengthening exercises done on both land and water.

Other: Combined Land- and Water-Based Exercise

Land-Based Exercise

ACTIVE COMPARATOR

Core and lower extremity strengthening exercises that are implemented solely on land.

Other: Land-Based Exercise

Water-Based Exercise

ACTIVE COMPARATOR

Core and lower extremity strengthening exercises that are implemented solely in water.

Other: Water-Based Exercise

Interventions

Strengthening exercises targeting the core and lower extremities (quadriceps, hamstring, and gastrocnemius) were implemented both on land and in water. The exercises are done for approximately one hour/day, three days/week for two consecutive weeks. The following are the included exercises: Land-based exercise: 1. Plank exercise 2. Russian twist 3. Push-up 4. Goblet squat 5. Kettle bell swing Water-based exercise: 1. Flutter kicks 2. Isometric core crunches 3. Jump lunges 4. Kicks 5. Resisted knee flexion

Combined Land- and Water-Based Exercise

Strengthening exercises targeting the core and lower extremities (quadriceps, hamstring, and gastrocnemius) were implemented on land. The exercises are done for approximately one hour/day, three days/week for two consecutive weeks. The following are the included exercises: 1. Plank exercise 2. Russian twist 3. Dead bug 4. Push-up 5. Goblet squat 6. Nordic hamstring curl 7. Lunges 8. Kettle bell swing 9. Calf raises 10. Bird dog

Land-Based Exercise

Strengthening exercises targeting the core and lower extremities (quadriceps, hamstring, and gastrocnemius) were implemented in the water. The exercises are done for approximately one hour/day, three days/week for two consecutive weeks. The following are the included exercises: 1. Core pulls 2. Flutter kicks 3. Water cycling 4. Isometric core crunches 5. Seated push-up 6. Jump squats 7. Jump lunges 8. Kicks 9. Ankle jumps 10. Resisted knee flexion
