Proprioceptive Neuromuscular Facilitation Warm-Ups: A Key to Improved Isokinetic Performance

Abstract

This study examined the immediate effects of proprioceptive neuromuscular facilitation warm-ups on isokinetic strength, endurance, and body balance in 50 football players. Data collection spanned four sessions, each separated by full rest. The isokinetic strength of the hip, knee, and ankle flexion and extension was measured using a dynamometer at 60 degrees/s, 180 degrees/s, and 240 degrees/s. Endurance was assessed at 240 degrees/s through 25 repetitions, analyzing peak torque changes. On the first day, participants performed general warm-ups followed by balance and strength tests. Subsequent sessions repeated these tests with additional measurements. Results showed that proprioceptive neuromuscular facilitation warm-ups significantly improved the static and dynamic balance compared to other methods. Peak torque measurements at all speeds also highlighted the superior effectiveness of proprioceptive neuromuscular facilitation warm-ups. Additionally, this warm-up approach provided greater acute enhancement in knee joint isokinetic endurance. In conclusion, proprioceptive neuromuscular facilitation warm-ups increased the isokinetic strength, endurance, and balance in football players. Incorporating proprioceptive neuromuscular facilitation warm-ups into football training especially for lower body preparation is recommended. Combining them with active warm-ups may further boost acute performance.
