Hamstring injuries are among the most prevalent in sports, accounting for 12-16% of all injuries in elite football (Ekstrand et al., 2011) and a leading cause of time lost in sprint-based sports. Additionally, research suggests that hamstring strength is a key predictor of sprint performance, with elite sprinters exhibiting 20-30% greater eccentric hamstring strength compared to sub-elite athletes (Timmins et al., 2016). Given these statistics, a structured and research-backed approach to hamstring training is essential. To train your hamstrings effectively, you must go beyond traditional strength exercises and incorporate a well-rounded strategy backed by scientific evidence. This article explores five key principles for optimal hamstring development, supported by peer-reviewed medical and sports science literature.
Eccentric training (lengthening contractions under load) is a gold-standard method for reducing hamstring injuries and improving performance. Nordic hamstring curls have been widely studied for their ability to enhance eccentric strength and reduce injury risk.
Research by van Dyk et al. (2019) found that teams using Nordic hamstring curls reduced hamstring injuries by up to 51%.
A systematic review by Al Attar et al. (2017) concluded that eccentric hamstring exercises significantly lower the risk of re-injury, particularly in football and sprint-based sports.
Nordic Hamstring Curl: Proven to increase fascicle length and eccentric strength (Presland et al., 2018). It's important to sufficiently load your hamstrings are in a lengthened position (when you're close to hitting the floor). I like to assist athletes with a band to make this exercise more effective.
Romanian Deadlift (RDL): Strengthens hamstrings through hip extension while improving control over the eccentric phase. Try doing a staggered or B stance RDL to ensure you are loading each leg equally.
Sliding Hamstring Curls: Engages hamstrings through both knee flexion and hip extension. If you don't have sliders, wooly socks on timber flooring will work fine.
Hamstring function involves two main movements: hip extension (e.g., during deadlifts) and knee flexion (e.g., during leg curls). Research suggests training both movements for optimal strength and resilience.
A study by Bourne et al. (2017) found that both hip-dominant (RDLs) and knee-dominant (Nordic curls) exercises improve hamstring muscle architecture, reducing injury risk.
Timmins et al. (2016) found that longer hamstring fascicles from combined training are linked to lower injury rates.
Hip-Hinge Based: Romanian deadlifts, Good mornings, Hip thrusts
Knee-Flexion Based: Nordic hamstring curls, Lying hamstring curls, Swiss ball leg curls
Plyometric training enhances the hamstrings’ ability to generate force quickly and absorb high-impact loads, essential for sprinting, jumping, and agility.
Lacome et al. (2020) highlighted that plyometric drills improve hamstring stiffness and force absorption, reducing the risk of sudden overload injuries.
Markovic & Mikulic (2010) demonstrated that explosive plyometrics enhance rate of force development (RFD) in lower limbs, critical for sprinting and jumping.
Bounding & A-Skips: Enhances hamstring stiffness and sprint mechanics.
Hamstring Tantrums: Works on producing speed and power in the proximal range. For this exercise you lie on your stomach. You can use either a Swiss Exercise ball or a Resistance band tied around a secure squat rack.
Resisted Broad Jumps: Builds horizontal power output, which is sprint-specific.
Sprint exposure is often neglected in injury prevention programs. Research has shown that most field-based athletes do not expose themselves to top speed running on a weekly basis. However, sprinting at maximal velocity is one of the most effective ways to strengthen the hamstrings dynamically.
Mendiguchia et al. (2020) showed that sprinting recruits the hamstrings at high force outputs, making it crucial for sport-specific conditioning.
Schache et al. (2012) confirmed that the hamstrings experience their greatest eccentric loads during the late swing phase of sprinting.
Include maximal sprint efforts (≥90% of top speed) 1-2 times per week.
Progressively increase sprint volume to reduce injury risk and improve sprint mechanics.
You can also consider using resisted sprints (sled drags) to strengthen the posterior chain further. However, this should not be considered top speed running.
Hamstring health is also influenced by synergistic muscles that support lower-limb function. Weak core, glutes, hip adductors, or calves can shift excessive load to the hamstrings, increasing injury risk. The good news is that we can incorporate core strengthening exercises into a lot of lower limb exercises, reducing the need for a long list of exercises.
Mendiguchia et al. (2015) found that weak glute max activation correlates with hamstring overuse and strain injuries.
De Ridder et al. (2021) emphasized adductor training to balance hip mechanics and reduce strain on the hamstrings.
Ruggiero et al. (2019) showed that calf strength deficits contribute to lower-body instability, indirectly affecting hamstring resilience.
Glutes: Hip thrusts, Bulgarian split squats, Step ups
Adductors: Copenhagen planks, Lateral lunges
Calves: Soleus & gastrocnemius raises (bent and straight leg calf raises), Pogo jumps
Proprioception refers to the body's ability to sense movement, position, and force. Think of it like this, even with your eyes closed, if someone was to bend your knee, you would know it is now in a bent position. This is of course, an oversimplification of what proprioception is. The hamstrings, crossing both the hip and knee joints, require precise coordination to function efficiently. Deficits in proprioception increase the likelihood of hamstring injuries by impairing balance, joint stability, and neuromuscular timing, leading to excessive load on the muscles during high-speed activities such as sprinting and sudden direction changes (Huang et al., 2021).
A study by Freeman et al. (2022) demonstrated that athletes undergoing proprioceptive retraining had a 30-50% lower risk of hamstring reinjury compared to those receiving conventional strength and flexibility training alone. This reduction is attributed to improved neuromuscular control, which optimizes muscle activation patterns and reduces erratic joint movements that place excessive stress on the hamstrings.
Another systematic review by Hrysomallis (2023) found that proprioceptive training enhanced lower limb coordination, decreased reaction time to perturbations, and reduced injury recurrence in previously injured hamstrings by 40-60%. This aligns with research highlighting that poor postural control and proprioceptive deficits are major risk factors for hamstring strains.
To effectively train your hamstrings for injury prevention and athletic performance, you need a multi-faceted approach:
By integrating these evidence-backed strategies, you’ll build hamstrings that are not only strong but also resilient, explosive, and ready to perform at an elite level. In defiance of Adequacy.
