Comparative Effects of Modified Tabata Training and Fartlek Training on Strength, Power and Endurance in Amateur Football Players

Riphah International University·interventional·Posted Jan 12, 2026·Updated Jan 12, 2026

In Brief

A clinical study evaluating Modified Tabata Training and Fartlek Training for Sports Physical Therapy. Completed, enrolled 34 participants across 1 site.

Detailed Summary

Background: Football requires players to excel in both high-intensity, fast-paced actions and slower moments of rest, which demand a range of well-developed motor skills, including power, endurance and strength. Endurance enables players to maintain prolonged physical effort without diminishing performance, a necessity given the sport's demand for players to cover 9-14 km per game, with up to 15% of this distance covered in high-intensity sprints. Strength is also crucial, helping players perform actions such as jumping, pushing during sprints, and maintaining stability, all of which enhance performance and resilience on the field. To adapt to the changing physical demands of football, training methods like treadmill sprint training and fartlek training (FT) are commonly used, each with different impacts on physiological development. Objective: The objective of this study is to compare the effects of treadmill sprint training and fartlek training on leg press strength, power and endurance on amateur football players. Methodology: A sample size of 42 football players will be randomly allocated to either fartlek training group or modified Tabata training group. A typical fartlek session begins with a warm-up, followed by intervals of intense effort (e.g., 2, 3, 4, 3, 2 minute hard and moderate runs) with recovery periods (2 minutes) in between, then concludes with a cool-down. This 2, 3, 4, 3, 2 interval set helps athletes improve endurance, strength and power and adapt to varied game-like conditions. The Modified Tabata training Program that will be carried out for 3 sessions per week over 6 weeks is as follows: there will be 3 training sessions in a week. In first two weeks, the 24-minute session will be divided into 6 sets, each set lasting 4 minutes consist of 8 rounds, with a 2-minute rest period between each set. The 4 minute exercise duration will consist of a work-to-rest ratio of 20 seconds of work and 10 seconds of rest. The level of exercise progressively increased throughout the 6-week program, by increasing the set of exercise Outcome measures in the both groups will be assessed by Squats test, Vertical jump test,3-min step up test and Yo-Yo Intermittent recovery test . All these measures will be taken at the baseline and again after 6 weeks of training to assess the effectiveness of the training program and the resulting improvements in strength, power, and endurance.
