Unilateral vs Bilateral Training – Part 2: Performance outcomes

Unilateral vs Bilateral Training – Part 2: Performance outcomes

In part 1 of this blog, we discussed the generalities associated with bilateral vs unilateral training. In part two, we discuss the findings of a scientific systematic review and metaanalysis (essentially getting all the papers published in the area and collating the data. The paper by Liao et al (2022) discusses how the type of training effects strength, jump performance, speed and change of direction.

Strength Gains:

Unsurprisingly, one of the key findings of the review was that both unilateral and bilateral resistance training interventions led to significant improvements in strength measures. However, the analysis revealed that bilateral training demonstrated a slightly greater effect on maximal strength gains compared to unilateral training. This is primarily attributed to the increased activation of synergistic muscles and neural adaptations that occur when both limbs are engaged simultaneously.

Jump Performance:

Jumping ability is a crucial determinant of athletic performance. The review highlighted that both unilateral and bilateral resistance training had positive effects on jump performance, particularly in terms of vertical jump height and power. However, when comparing the two training modalities, bilateral training showed a slight advantage in eliciting greater improvements in vertical jump performance. The increased activation of the lower limb muscles during bilateral exercises likely contributes to enhanced explosive power.

Linear Speed:

Again, the findings of the review indicated that both unilateral and bilateral resistance training interventions can improve linear speed to a similar extent. Unilateral training, focusing on the individual limb, has been shown to improve stride length and stride frequency, which are essential determinants of sprinting speed. On the other hand, bilateral training enhances muscular power and coordination, leading to improvements in overall running speed.

Change of Direction Speed:

Change of direction speed, commonly assessed through agility tests, is crucial for sports that involve rapid changes in movement direction. The meta-analysis revealed that both unilateral and bilateral resistance training interventions significantly improved change of direction speed. However, unilateral training appeared to have a slightly greater effect on agility performance. Unilateral exercises require greater stabilization and control from individual muscles, which can enhance an athlete’s ability to decelerate, change direction, and accelerate again quickly.

In summary, based on the systematic review and meta-analysis, both unilateral and bilateral resistance training interventions have positive effects on measures of strength, jump performance, linear speed, and change of direction speed. While bilateral training may lead to slightly greater improvements in maximal strength and vertical jump height, unilateral training may offer a slight advantage in terms of change of direction speed. It is important to note that the choice between unilateral and bilateral training should be based on individual goals, sport-specific requirements, and the patient’s needs. Therefore, sports physiotherapists and strength and conditioning coaches should carefully consider these factors when designing exercise programs to optimise outcomes for their patients.

Remember, it is always recommended to consult your qualified Praxis physiotherapist before starting any exercise program, especially if you have pre-existing medical conditions or injuries. We can provide personalised guidance and ensure that your training program aligns with your specific needs and goals.

Fact or Fiction – Strength Training

Fact or Fiction – Strength Training

I’ve been doing my exercises for two weeks religiously and I’m no stronger! This will never work!

ANSWER: Fiction

How long does it take to have strength gains? The answer is actually in two parts. Increasing muscle size (hypertrophy) takes a minimum of 6 weeks, and repetitive exposures to fatiguing loads. BUT, neural adaptations can occur over the first 1-2 weeks.

What the heck is neural adaptations? Imaging you have a small car battery trying to start a truck. It will struggle to do a good job again and again and fade easily. Now try using 10 of those same smaller batteries, which makes the engine start easier. A similar type of thing happens with our nervous system as we train. We become much more efficient with our neural firing to the muscle.

As you can see in the picture below, you have a long way to go in your strengthening after those first two weeks. That is often why we often need to see beyond when the pain goes away as we know that there is so much more work to be done!

FACT OR FICTION: Meniscus Tears and knee surgery

FACT OR FICTION: Meniscus Tears and knee surgery

All meniscal tears need surgery 🤔🔪🔪🔪🔪 ???

ANSWER: FICTION

In a recent meta-analysis (multiple studies combined), Kise and colleagues concluded that a small but inconsequential benefit is seen from treatment interventions that involve arthroscopy.

However, this small effect is of short duration and absent one year post surgery. Only 1 in 5 randomised controlled trials found greater pain relief 12 months after partial meniscectomy compared with non-surgical treatment! Further, the supervised exercise therapy showed positive effects over surgery group in improving thigh muscle strength, at least in the short term🙌

If you do NOT have mechanical symptoms (locking specifically), these results should encourage individuals with degenerative meniscal tears and no definitive radiographic evidence of osteoarthritis to consider supervised exercise therapy as a treatment option. Translation: Get strong and get moving under the care of a skilled physio like us at Praxis 💪🏃!

If your knee pain is holding you back, put a spring back into your step with Praxis Physio. We can accurately diagnose your issues, highlight where we can help, and get back on the path to improved function. To make a booking, call (07) 3102 3337 or book online

Congratulations Nancy!

GRADUATION

A massive congratulations to our resident remedial massage guru Nancy! She recently “doffed the cap” during her graduation ceremony. Nancy successfully completed a Bachelor of Health Science (Myotherapy) at the Endeavour College of Natural Health.

Myotherapy involves an extensive physical evaluation and an integrated therapeutic approach in the treatment of affected muscles, joints and nerves. Nancy gains an in depth understanding of human biology, musculoskeletal anatomy and function. Through extensive practical classes and clinical experience, graduates such as Nancy learn to conduct testing and physical assessments and apply a variety of practical skills such as myofascial release, dry needling, joint mobilisation and trigger point therapy.

Nancy continues to service her loyal massage followers on Tuesdays and Fridays at our Teneriffe location (91 Commercial Rd). You can book online here.

Well deserved Nancy – we are all proud of you!

ALICE SPRINGS

Cam and Steve finish their week at the National Indigenous Cricket Carnival (NICC) as the central Physiotherapists representing Cricket Australia and Praxis. The NICC has been created to further advance and develop Indigenous cricket. The competition provides greater playing opportunities in Alice Springs, but also forms a deeper connection with Australian cricket’s high performance pathway.

They were busy providing their expertise to over 10 male and female cricket teams who didn’t have a travelling physio accompanying them to Alice Springs. With over 150 consults in a week and 12 hour days as a minimum, our principal physio’s leave the tournament a little weary but proud of the standard they maintained during their stint in the Red Centre.

During the week of the championships, a special screening of Walkabout Wickets, a documentary commissioned by Cricket Australia commemorating the 150th anniversary of Australia’s first cricket team to go on an international tour. There was a preview screening aired in the Alice Springs’ Todd Street Mall as well as on Channel 7. The documentary will be free to stream for the next few weeks on 7Plus. Stephen was fortunate enough to be on that tour providing physiotherapy services for both the national men’s and women’s indigenous sides .

Both Cam and Steve are back in clinic on Wednesday looking forward to living the Prevent Prepare Perform mantra at our HQ in Teneriffe.

Until Next time

Private Health and Pilates – Changes for April 1st 2019

SUMMARY:

  • Private Health Rebates don’t apply for Pilates after the 1st of April
  • After April 1, Members can still claim private health for Pilates when classes are lead by a physio
  • The term “Clinical Pilates” will be replaced with “Physiotherapy Exercise Sessions”
  • To understand the difference between Reformer Pilates and Physiotherapy Exercise Sessions (formerly Clinical Pilates) 
  • Physiotherapy and Remedial Massage reman as is

From April 2019, private health insurance will no longer cover a number of natural therapies, including pilates. These changes were announced by Health Minister Greg Hunt late last year. This move comes after a recent review by the Commonwealth Chief Medical Officer found there was no clear evidence of the efficacy of several therapies including homeopathy, iridology, kinesiology, naturopathy, reflexology, shiatsu, tai chi, and yoga.

However, the Australia Physiotherapy Association (APA) has won a hard fought battle ensuring Pilates exercises prescribed by physiotherapists as part of an individualised program will continue to receive rebates in one-on-one, group and class settings. Great news for all of you who are already using our Pilates at Praxis!

The Department of Health has just released its final clarification on the Rules governing its Private Health Insurance (PHI) reforms and agreed with our position that the use of exercises drawn from Pilates are acceptable and within the scope of physiotherapy practice.

Pilates-only sessions will no longer be funded as of 1 April 2019. The reform of natural therapies was designed to eliminate rebates for non evidence-based therapies, and not intended to impact physiotherapy.

However, there are some things that will change! These include:

Advertising and Promotion

Advertising and promotion of sessions must reflect the fact that they are physiotherapy exercise sessions, not Pilates.

Scheduled physiotherapy exercise classes advertised or promoted as Pilates—in material such as timetables, pamphlets and online—cannot lawfully receive rebates.

This Rule does not affect other types of marketing material such as our business name, practice signage and branding. It’s perfectly acceptable for us to incorporate the word Pilates in our branding, and in fact to offer Pilates-only classes that do not attract rebates.

However, sessions eligible for rebates by private insurers cannot consist solely of Pilates and therefore cannot be called Pilates in any timetables, promotion or advertising. We must therefore use the term “Physiotherapy Exercise Sessions” when referring to what once was coined, Clinical Pilates.

Private Health Insurance (PHI) compliance

The key to PHI compliance is the basic foundations of individualised assessment, follow up and record keeping that should already underpin our clinical pilates practice. To comply with current PHI requirements, physiotherapists must create:

  1. Individualised assessment of patients in one-on-one, group sessions and classes.
  2. A program of exercised-based interventions specific to the patient. In group sessions this includes adjusting the group program for individuals as required. In both groups and classes, the exercises should address a current health problem.
  3. High quality clinical notes that reflect physiotherapy practice.

So, there you have it. There are some sweeping changes coming to this space which we think are a good thing. Changing coverage for the excluded natural therapies will ensure taxpayer funds are spent appropriately and are not directed to therapies that do not demonstrate evidence of clinical efficacy. Changing coverage for the excluded natural therapies will remove costs from the system and contribute to reducing private health insurance premium growth.

If you have any questions, please don’t hesitate to contact us or your Private Health insurer or alternatively the governments own website.

Until next time… Prevent. Prepare. Perform.
