Static vs dynamic stretching. What’s the difference and what should I be doing?

When it comes to preparing your body for a workout, the notion of static stretching as a warm-up is facing a considerable challenge. Recent research is uncovering potential drawbacks, revealing that this traditional approach might not be the performance booster we once believed it to be. In fact, static stretching could have the counterintuitive effect of decreasing muscle power for hours post-stretch, potentially hindering your athletic performance.

The promise of injury prevention often associated with static stretching seems to fall short in the scientific realm. Studies are urging fitness enthusiasts to pivot toward dynamic exercises for a more effective warm-up routine. Dynamic exercises, such as proprioceptive training, strength workouts, and dynamic warm-ups, are emerging as champions in preserving performance levels and reducing the risk of injuries.

The shift from static to dynamic warm-ups has a growing evidence base. Dynamic exercises engage your muscles in a way that static stretching simply doesn’t. They prepare your body for the dynamic movements that lie ahead in your workout, enhancing flexibility, blood flow, and overall performance. As we bid adieu to the old-school static stretches, consider embracing a new era of warm-up routines that incorporate dynamic, agility, strength, and balance exercises for superior results.

So, before you settle into that long-held stretch pre-workout, take a moment to reassess. Your body might just thank you for the switch, unlocking a new realm of athletic potential and injury prevention. After all, in the dynamic world of fitness, adaptability is key. ????????

Hamstring injury management – A breakdown of the latest research

Sliding exercise

Athletes rejoice! For decades our understanding of hamstring (HS) injuries has been improving and evolving, yet the frequency of HS injury rates in sport have not declined. Finally, a new paradigm has been developed which consolidates our knowledge of the anatomy and the physiology of this highly prevalent injury, applies effective rehabilitation strategies, accurate return to sport testing and re-injury prevention.

We can broadly define the typical hamstring strain into a sprinting type strain which occurs at high speed running versus a stretch type strain which occurs with high kicking or other stretching movements. Each of these will typically cause an injury to a different muscle in the hamstrings group. They can generally be diagnosed in the clinic without the need for any imaging. The most common type is the sprinting type, frequently seen in football codes, soccer, hockey, athletics and other running sports. The stretch type is more common in dancers, jumpers and hurdlers, although either type can occur in any sport. Knowing the type of injury gives us a chance to apply the right exercise rehab as well as gives a guideline for the return to sport time, which varies enormously between the type, location and grade of strain.

We know that most HS injuries occur when the muscle is working hard in its lengthening phase, therefore it is essential that the rehabilitation program targets this movement at high load. A comprehensive program is undertaken, which incorporates hamstring strength, but also hip, pelvis, trunk and general lower limb strength and stability. This addresses all the factors which will lead to re-injury – that’s not new. What is new is a set of 3 specific exercises, that when applied correctly in soccer players led to a re-injury rate of only 1 in 75 players over 12 months! That’s way down from the average 1 in 4 players with conventional rehab in professional soccer.

The protocol is based on 3 specific lengthening (eccentric) strength exercises and the technique, timing and progressions of these are of critical importance, they need to be integrated and complemented with other exercises and, as a rule, should be pain free. So what can you expect to gain from completing a modern rehab program like the one we provide at NU Moves? A research study by Askling and colleagues found that their protocol of exercises led to an average return to play time of 28 days, compared with 51 days for the conventional group. Combining this with the low reinjury rate means it was proven to be a much better approach to HS rehab. The research also provided an additional return to play testing procedure (H test), which we integrate into our comprehensive existing return to play algorithm in the clinic. It assesses apprehension or feeling of insecurity as well as pain when performing a high load eccentric braking action on the leg, similar to what happens during an injury but in a safe way.

So to put it all together, we have a rehab protocol that fits well with our current understanding of hamstring strains and their risk factors. It is easy and inexpensive to perform once taught. It also reduces the time to return to play and gives better long-term outcomes. If you are ever unlucky enough to be in this position, then things are looking better now than they ever have!

Running biomechanics and muscle strength

Running physiotherapy injury

 

Biomechanics refers to how we are built and how we move. Some of us have legs that bow out (varus alignment) and others have knock knees (valgus alignment) which relates to the shape of our bone structure. It is a combination of our bony structure and how well our muscles work that can increase the likelihood of injury with running. This blog is looking at key areas of muscle weakness that alter our biomechanics and lead to injury. Your bony structure can’t be changed but improving your strength in the right areas can be achieved within 6 weeks of an exercise program that is designed for you. Assessing the biomechanics of the body combined with a basic understanding of your running style is important if you are serious about running.

A biomechanical physiotherapy assessment considers whether you have sufficient strength and mobility in the right places for running. The muscles in the back of the leg (calf, hamstring and gluteal) are important to maintain strength for running. Weakness in these muscles often leads to pain and injury in runners.

  • Calf muscle and Achilles tendon strength – it is important to understand that both muscles and tendons can respond to the loads we put on them. A simple test and exercise for the calf and achilles is the calf raise. If you can’t do a repeated full height single leg calf raise of more than 6 reps than you probably don’t have enough strength. I encourage people to get to 15 reps and be able to repeat 3 sets as a baseline but there isn’t a magic number here because it also depends on your running style. If you are about to change your style and get further forwards on the forefoot then check your calf and achilles strength first to minimise the chance of getting achilles tendon problems.

  • Hamstring strength is essential for fast running but a base level of strength is also important for your park runners to 10km distances. Clearly the most functional way to strengthen the hamstrings for running is to gradually increase the distance and intensity of your running sessions. If you can’t do a hamstring bridge exercise or it takes considerable effort then you need to get stronger. Caution with doing this exercise – if it causes back pain then stop and discuss with one of our physio’s.

  • Gluteal (buttock muscle) strength allows for a stable pelvis during running. If you don’t have adequate gluteal strength it puts extra load on the knees, hips and lower back. Unless you have had a biomechanical physio assessment you probably don’t know if your glut’s are working well enough. A glute bridge is similar to a hamstring bridge but the knees are bent at approximately 90°. By bending the knees it makes it harder to use the hamstrings to lift the bottom and thus challenges the gluteal muscles more. Again if you have back pain stop and get some advice.

  • A squat is another good exercise to get the glute muscles working for runners but it needs to be done correctly. Keeping the back straight and bending at both the knees and hips gets the gluteal muscles working. Once you have been taught to do a squat correctly the challenge is a single leg squat with letting the knee drop in valgus collapse.
