Dynamic Strength Index-based Intervention in Basketball.

December 4, 2024 updated by: Žiga Kozinc, University of Primorska

Effectiveness of an Individualized Training Based on Dynamic Strength Index on Sprinting, Jumping and Change of Direction Performance in Basketball Players: a Randomized Controlled Trial.

The goal of this randomized controlled trial will be to determine the effectiveness of the dynamic strength index (DSI) in optimizing training programs to improve physical performance proxies (sprinting, jumping, and CoD) in basketball players. Subjects will be randomly allocated to one of two groups: the intervention group and the control group. Measurement and intervention will occur during a 7-week in-season period, right before the play off starts. Throughout this period, all participants will engage in an average of 10 hours of basketball training per week, which will comprise 5 basketball sessions and 2 strength training sessions. In addition, they are anticipated to play 2 games weekly. A pre-test will be performed one week before the first training session, and post-tests will be performed in the week after the training sessions have finished. Athletes will perform both testing sessions at the same time of the day (± 2 hours). Each athlete will perform a 20-m sprint test, with timing gates positioned at every 5 m distance, a 505 CoD test, countermovement jump (CMJ), and isometric mid-thigh pull (IMTP). Based on CMJ peak force and IMTP peak force data, we will calculate DSI. Based on the average DSI value, the participants in the intervention group will be divided into two groups - strength group and ballistic group.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Perform basketball training for at least 5 years
  • Plays in professional regional, national or international league

Exclusion Criteria:

  • Any musculoskeletal injury in the past 6 months
  • Any neurological issues
  • Any chronic non-communicable diseases

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: DSI-based training group
This group will perform resistance exercises based in their DSI values.
Other: Resistance training based on DSI value
The intervention consist of modifying the ongoing resistance exercises. Those with low DSI values will perform ballistics, explosive exercises. Those with high DSI will perform heavy-load training. The resistance training program will consist of 2 sessions per week for 5 weeks (10 sessions in total). The sessions will be separated by a minimum of 48 hours. The strength training group will consist mostly of exercises with high load, whereas the ballistic training group will perform ballistic exercises with low load or without any additional load. The training principle will be the same for both subgroups, consisting of 3 exercises per training session and a total of 6 exercises per week, with four of the exercises being bilateral, one unilateral, and one quasi-unilateral (Bulgarian split squat and scissor jumps).
Active Comparator: Normal training group
This group will perform a normal, typical resistance exercise program
Other: Normal training group
The participants will do a general training program (not based on DSI values). The resistance training program will consist of 2 sessions per week for 5 weeks (10 sessions in total). The sessions will be separated by a minimum of 48 hours. The strength training group will consist mostly of exercises with high load, whereas the ballistic training group will perform ballistic exercises with low load or without any additional load. The training principle will be the same for both subgroups, consisting of 3 exercises per training session and a total of 6 exercises per week, with four of the exercises being bilateral, one unilateral, and one quasi-unilateral (Bulgarian split squat and scissor jumps).
