A study testing eccentric cable leg curls and eccentric banded leg curls in people with Hamstring Muscle and Muscle Strength, run by Riphah International University at 1 site in Pakistan.
Trial summary
Hamstring injuries are highly prevalent among cricket players, comprising 10% of all injuries in field-based team sports. Eccentric strength deficits and imbalances in muscle strength are linked to a higher risk of such injuries. Read more about this study

About this study
Official title: Effects of Eccentric Banded Leg Curls Versus Eccentric Cable Leg Curls Exercises on Eccentric Knee-flexor Strength, Power and Endurance in Cricket Players
Hamstring injuries are highly prevalent among cricket players, comprising 10% of all injuries in field-based team sports. Eccentric strength deficits and imbalances in muscle strength are linked to a higher risk of such injuries. Our randomized clinical trial aims to assess eccentric hamstring strength using eccentric banded leg curls and eccentric cable leg curl exercises, measured by the Nordbord device. This tool provides accurate measurements of eccentric hamstring strength, power, and endurance, crucial for injury prevention in athletes. Thirty-two male professional cricketers will participate, divided into two groups receiving different exercise plans. Each group will perform 15 reps in 3 sets with rest intervals, four times a week for four months. The Nordbord device will assess hamstring strength before and after the exercise plan. Statistical analysis will be done using SPSS V25, employing descriptive statistics for frequency distribution and inferential statistics such as t-tests to compare outcomes between treatment groups.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
eccentric cable leg curlsOther
The players will undergo eccentric cable leg curls, completing 15 reps of 3 sets every other day with 30-45 seconds rest between sets, a total duration of 40 minutes conducted four days a week over a four-month training period.
eccentric banded leg curlsOther
The players will undergo eccentric banded leg curls, completing 15 reps of 3 sets every other day with 30-45 seconds rest between sets, a total duration of 40 minutes conducted four days a week over a four-month training period.
| Study group | Role | What they receive |
|---|---|---|
| eccentric cable leg curls | Experimental | Group A players will perform eccentric cable leg curls Receives: Other: eccentric cable leg curls |
| eccentric banded leg curls | Active comparator | Group A players will perform eccentric banded leg curls Receives: Other: eccentric banded leg curls |
What is being measured
The primary outcome is the main question the study is designed to answer.
Eccentric hamstring strength
The NordBord is a great tool for measuring hamstring strength of each leg allowing for tracking of overall strength gains and side-to-side imbalances.
Measured: 4 months

Questions about this trial
What is this clinical trial studying?
A study testing eccentric cable leg curls and eccentric banded leg curls in people with Hamstring Muscle and Muscle Strength, run by Riphah International University at 1 site in Pakistan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 22 May 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Pakistan. Whether a site is taking part right now should be confirmed with that site. See every site.
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?
Eccentric hamstring strength (time frame: 4 months). 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 NCT06460883, which also lists 7 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 22 May 2025.
