Title: The Effectiveness of Muscle Energy Technique and Hamstring Nordic Lower Exercise in Managing Hamstring Tightness Among Young Athletes of Pakistan

Objective:

The primary objective of this study is to investigate the effectiveness of two interventions, the muscle energy technique and the hamstring Nordic lower exercise, in managing hamstring tightness among young athletes from Pakistan.

Background:

Hamstring tightness is a prevalent issue among athletes, which can lead to reduced flexibility, increased risk of injury, and impaired athletic performance. The muscle energy technique is a manual therapy approach that involves active muscle contractions and stretches to improve muscle flexibility and restore normal range of motion. Conversely, the hamstring Nordic lower exercise is a specific eccentric strengthening exercise that targets the hamstring muscles and aims to improve their lengthening capacity.

Study Design:

A randomized controlled trial will be conducted to evaluate the efficacy of the two interventions. Young athletes from Pakistan with hamstring tightness will be recruited as participants. They will be randomly assigned to one of two intervention groups: the muscle energy technique group or the hamstring Nordic lower exercise group. The interventions will be administered by trained healthcare professionals under supervision, following a specific duration and frequency.

Outcome Measures:

The primary outcome measure of interest in this study is the change in hamstring tightness. The measurement tools used to assess this outcome will be reliable and validated. Baseline assessments will be conducted before the intervention period, and post-intervention assessments will take place immediately after the intervention period.

Secondary outcome measures may include improvements in hamstring flexibility, functional performance, and self-reported symptoms related to hamstring tightness. These secondary measures will provide a comprehensive evaluation of the effectiveness of each intervention.

Data Analysis:

Data will be analyzed using appropriate statistical methods. The outcomes between the two intervention groups will be compared to determine the relative effectiveness of the muscle energy technique and the hamstring Nordic lower exercise in managing hamstring tightness.

Implications:

The findings of this research will offer valuable insights into the most suitable intervention for managing hamstring tightness among young athletes in Pakistan. This information can contribute to the development of targeted rehabilitation protocols and injury prevention strategies in this specific population. Furthermore, the results may also have broader implications for similar populations of athletes globally who face similar issues with hamstring tightness.

Conclusion:

By evaluating the effectiveness of the muscle energy technique and the hamstring Nordic lower exercise, this study aims to contribute to the advancement of evidence-based interventions for managing hamstring tightness. The results will be disseminated through scientific publications and presented at relevant conferences to ensure that the knowledge reaches the appropriate healthcare professionals, coaches, and athletes.

RANDOMIZED

Intervention Model

CROSSOVER

This triple-blinded, randomized clinical trial employed a five-phase crossover design to evaluate the effects of post-isometric relaxation, post-facilitation stretch, and hamstring Nordic lower exercises on hamstring function and athletic performance in young athletes. Participants were randomly assigned to treatment groups in Phase I, followed by washout periods in Phases II and IV. In Phase III, participants switched treatments to ensure exposure to all interventions. Outcome measures included hamstring flexibility, lower limb power, speed and acceleration, hamstring strength, and agility. The study utilized triple-blinding and randomization to minimize biases. The findings will guide practitioners and coaches in optimizing training and rehabilitation strategies for young athletes. In conclusion, this trial provides valuable insights into the effects of different treatments on hamstring function and athletic performance, benefiting athletes and enhancing performance outcomes.

Blinding Strategy

QUADRUPLE

Participants Caregivers Investigators Outcome Assessors

This triple-blinded randomized clinical trial ensured masking of participants, physiotherapists, assessors, and the principal investigator. Participants were unaware of their assigned treatment, as treatments were standardized and shared similar characteristics. Physiotherapists were trained to deliver treatments without disclosing specific interventions. Assessors remained blinded to treatment assignments, conducting outcome assessments independently. The principal investigator had no knowledge of treatment allocations to maintain objectivity. Implementing triple-blinding enhanced the study's internal validity, minimizing biases and improving the reliability of the results.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group A

20 participant randomly allocated they were administered in first phase with post facilitation stretch , 3rd phase with post isometric relaxation and then in 5th phase hamstring Nordic lower

Group Type EXPERIMENTAL

post facilitation stretch

Intervention Type OTHER

PFS Post-Facilitation Stretch Participants in this arm received the intervention of post-facilitation stretch technique. Post-facilitation stretch involves the application of manual stretching techniques to the targeted muscles after a facilitation phase, which aims to enhance muscle extensibility. The participants underwent a standardized post-facilitation stretch protocol focusing on the hamstring muscles.

post isometric relaxation

Intervention Type OTHER

Participants in this arm of the study received the intervention of post-isometric relaxation technique. Post-isometric relaxation involves the application of isometric contraction followed by a relaxation phase to promote muscle lengthening and improve flexibility. The participants underwent a standardized post-isometric relaxation protocol targeting the hamstring muscles.

hamstring nordic lower

Intervention Type OTHER

Participants in this arm received the intervention of hamstring Nordic lower exercise. The hamstring Nordic lower exercise is a challenging eccentric exercise that specifically targets the hamstring muscles.
