Does submaximal contraction equal maximal results? Exploring contract-relax proprioceptive neuromuscular facilitation (CRPNF) stretching for hamstring flexibility

In 2004, a randomized controlled trial conducted by J.B. Feland and H.N. Marin investigated the efficacy of submaximal contractions in contract-relax proprioceptive neuromuscular facilitation (CRPNF) stretching for enhancing hamstring flexibility. The study aimed to compare the effectiveness of submaximal contractions with maximal voluntary isometric contractions (MVICs) in improving hamstring flexibility. The trial involved 72 male participants aged 18-27, all of whom demonstrated tight hamstrings, defined … Continue reading Does submaximal contraction equal maximal results?

Unlocking flexibility: Can eccentric training match static stretching for high school athletes’ hamstring flexibility?

In 2004 a study conducted by Russell T. Nelson and William D. Bandy, et. al., the effectiveness of eccentric training and static stretching in enhancing hamstring flexibility among high school males was thoroughly examined. The objective was to ascertain whether a 6-week eccentric exercise regimen could bring about notable improvements in flexibility. Additionally, the study aimed to compare these changes with those resulting from a … Continue reading Unlocking flexibility: Can eccentric training match static stretching for high school athletes’ hamstring flexibility?

Can foam rolling and static stretching boost hip-flexion range of motion together?

Many athletes seek ways to improve their range of motion (ROM) and flexibility to enhance their performance. Foam rolling has gained popularity for its potential to release muscle tension, and static stretching is a common method for improving flexibility. In 2014, study by Andrew R. Mohr and colleagues aimed to investigate whether combining foam rolling with static stretching could significantly increase passive hip-flexion ROM. This … Continue reading Can foam rolling and static stretching boost hip-flexion range of motion together?

Which stretching technique reigns supreme for hamstring flexibility?

Flexibility is a key component of physical fitness, and achieving optimal hamstring flexibility is essential for various athletic activities and overall well-being. In 2010, a study led by Roberto Meroni and his team aimed to compare the effects of active and passive stretching techniques on hamstring flexibility. The study sought to determine which technique resulted in greater gains in flexibility and whether these gains were … Continue reading Which stretching technique reigns supreme for hamstring flexibility?

How effective is a modified stretching routine for prolonged hamstring flexibility?

In 2001, Spernoga, et. al., Enhancing flexibility which is a key component of optimizing athletic performance and reducing the risk of injuries. Proprioceptive neuromuscular facilitation (PNF) stretching techniques have been highlighted for their effectiveness in improving range of motion compared to other stretching methods like passive, ballistic, or static stretching. This study aims to investigate the duration of improved hamstring flexibility resulting from a unique, … Continue reading How effective is a modified stretching routine for prolonged hamstring flexibility?
