About this study
Official title: Combined Land- and Water-Based Core and Lower Extremity Strength Training in Improving the Jump Performance Among Volleyball and Basketball Players: A Randomized Controlled Trial
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.
Read the detailed description
Numerous studies focused on the effect of sole land- or water-based exercise training to improve either core and/or lower extremities alone, which could result in improved jump performance. With the continuously increasing popularity of volleyball and basketball, where players get better and better, competition in these fields is also heightened. Hence, identifying other methods to improve game performance, such as improving muscle strength and jump performance can be explored to contribute to the existing literature and could benefit the volleyball and basketball players themselves, trainers/coaches, universities competing in sports competitions locally, nationally, and even internationally, and to physical therapists who are venturing to sports physical therapy.
The study then seeks to investigate whether combined land- and water-based exercises targeting the core and lower extremity muscle strength can enhance the jump performance of basketball and volleyball players. With this, a three-arm, single-blinded randomized controlled trial is being conducted among basketball and volleyball players. Participants are grouped into combined land- and water-based exercise, land-based exercise, and water-based exercise.
To proceed with the implementation, the researchers acquired ethical clearance from the MMSU Ethics and Review Board. Recruitment of participants happened within a University at Ilocos Norte, Philippines. Acquisition of informed consent was done before other screening procedures to identify the eligibility of participants to participate in the study. Eligible participants were randomized accordingly to either the three (3) aforementioned groups.
The exercises implemented in each group are based on existing literature regarding their effect on either the core or lower extremity strength, and combined to create a new and applicable exercise program, These exercise programs were also verified applicable by two licensed physical therapists who are also well-versed in strength training protocols. The participants are being trained accordingly one hour/day, three days/week for two consecutive weeks.
As to the pre-and post-test measurements of the primary and secondary outcomes, assessment is done by two independent licensed physical therapists who are blinded to the participants and interventions. Moreover, the assessors are well-versed in the assessment of the different outcome measurements (Plank core strength test, 1RM, 10-meter Sprint Test, Margaria-Kalaman Power Test) and in using the MyJump Lab Mobile App, duly purchased by the researchers, used for the assessment of countermovement jump and squat jump.
The SPSS version 22 will be used for data analysis by an independent statistician. Descriptive and comparative statistics will be used to analyze all data within- and between-groups, respectively. For the descriptive statistics, frequency, percentages, mean, and standard deviation will be utilized, while the two-way ANOVA and/or the paired T-test will be utilized for the comparative statistics.

Best time for plank will be assessed, measured in seconds (s). Pre- and post-test measurement will be gathered.
Measured: 2 weeks
Quadriceps-Hamstring Strength
This outcome measure used the 1RM of the participant, measured in pounds (lbs), as measurement of Quadriceps-Hamstring strength. Pre- and post-test measurement will be gathered.
Measured: 2 weeks

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Vertical Jump (time frame: 2 weeks). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06412809, which also lists 15 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 May 2024.
