Romanian Deadlift Vs. Standard Deadlift: Comprehensive Guide

By Kyran Doyle In Training

Deadlifts are one of the best strength and mass building exercises that you can perform. When performing the deadlift you are working more muscles than any other exercise, including the squat.
Deadlifts have many different variations and forms. In this article we are going to focus on the difference between the Romanian Deadlift and standard deadlifts.
There are lots of valid arguments as to which exercise is better in a Romanian Deadlift vs regular deadlift battle.
Keep reading to learn the differences. Romanian Deadlift Vs. Standard DeadliftThe Romanian Deadlift is one of the most commonly used among the various deadlift techniques. In fact a lot of people that think they are performing a deadlift are sometimes actually doing a Romanian Deadlift.
Both the conventional and Romanian Deadlifts are great strength and muscle building exercises. Even though they are both deadlifts variations the setup, execution and muscles activated are different.

Acute Hamstring Injury Rehab


Chiropractor, Dr. Alexander Jimenez explores the advantages of using eccentric strengthening in rehab for a faster Return-to-play following severe hamstring injuries.

Sporting activities involving high demands of sprinting or excessive stretching (kicking, slipping, split positions) are found to affect the incidence of severe hamstring injuries. Hamstring injuries are varied in character comprising differing injury types, location and size. This makes recommendations concerning rehabilitation and prognosis about healing time plus return-to-play notoriously difficult. It’s been suggested that reunite- to-play timescales change between 28-51 days after acute hamstring injuries based upon the biomechanical cause, site, and evaluation of soft tissue injury(1). However, this is a controversial issue, which this report will explore.

After a return to game, the probability of re-injury is high within the first 2 weeks(2). The causes are linked with first hamstring weakness; fatigue; a lack of flexibility, and a strength imbalance between the hamstrings (bizarre) and also the quadriceps (concentric)(2). The greatest contributory factor however, is believed to be an inadequate rehabilitation program, which coincides with a premature return to sport(3). More proof is now highlighting the advantage of mostly using eccentric strengthening exercises at hamstring rehab performed at large loads at more musculotendon lengths(1,4).

Semitendinosus (ST), they’re involved with extension of the hip, flexion of the knee as well as providing multi-directional equilibrium of the tibia and pelvis. All 3 muscles cross the posterior component of the two hip and the knee joints which makes them biarticular. As a result, they need to continuously react to large mechanical forces created by upper limb, trunk and lower limb locomotion via concentric and eccentric contractions. These forces are greatly improved during athletic activity, which is a likely culprit due to their high injury frequency.



In a study at the University of Melbourne, biomechanical analysts quantified the biomechanical load (ie musculotendon strain, speed, force, power, and operate) experienced by the hamstrings across a full stride cycle during over-ground sprinting, as well as the biomechanical load across each person hamstring muscle(4).

Firstly, the hamstrings undergo a stretch-shortening cycle through sprinting, with the lengthening phase happening during the terminal swing and shortening phase commencing before foot attack, and ongoing throughout the stance. Secondly, the biomechanical load on the biarticular hamstring muscles has been found to be best during the terminal swing.

BFLH had the biggest peak musculotendon strain, ST demonstrated the best musculotendon lengthening velocity, and SM produced the greatest musculotendon force as well as absorbing and generating the maximum musculotendon power. This has ties in with other similar research, which divides peak musculotendon strain as a large contributor to eccentric muscle damage, ie hamstring injury, instead of peak muscle power(1); hence the recommendation of bizarre strengthening for acute hamstring rehabilitation.

Site Of Injury & Grading Classification

In a randomised controlled trial Professional Swedish footballers(1), the primary injury was situated in BFLH (69%). This contrasted with 21% of those players that sustained their principal harm within SM. It was common to maintain a secondary harm to ST in addition to BFLH (80\%) or SM (44%). A clear majority (94\%) of the most important injuries were discovered to be of the sprinting-type and were located in the BFLH, whereas, SM was the very common (76 percent) location because of the stretching- kind of harm. These findings were supported in another similar post(5).

Typically (see Table 1), classification for Acute soft tissue injury, such as hamstrings, has depended on a grading system of I (moderate), II (mild), or III (severe) (2,6,7). This classification is useful concerning coherent descriptions between different medical staff members during clinical diagnosis and prognosis following severe injury.



The British Athletics Medical Team Suggests a new injury classification system for improved diagnostic precision and prognostication based on MRI attributes (see Table 2 and figure below revealing ‘letter classification) (5).





Discovering true return-to-play Timescales following a severe hamstring injury has proven difficult. Injuries involving an intramuscular tendon or aponeurosis with adjoining muscle fibers (BF during high-speed running) typically require a shorter recovery period compared to those involving a proximal free limb or MTJ (SM during dancing or kicking)(2).)

Additionally, There Are connections between MRI Findings as well as the area of injury, and return-to-play. Likewise, the length of oedema indicates a similar effect on healing period — ie the longer the length, the more the retrieval(1). In addition, the place of peak pain on palpation following severe injury can also be linked with increased healing intervals(1).

Moreover, there have been efforts To explain the link between grading of acute hamstring injury and return-to-play. In a prospective cohort study on 207 professional footballers with severe hamstring injuries, 57 percent were grade I, 27 percent were grade II, and 3 percent were grade III. Grade I injuries returned to perform inside a mean of 17 days. Grade II was 22 days, and grade III was 73 days. Eighty four percent of those accidents affected the BF, 11\% SM, and 5\% ST, however there was no substantial difference in lay-off time for injuries to the 3 different muscles(5). This has been compared to 5-23 times with regular I-II injuries, and 28-51 times for grade I-III in other research respectively (1,8).

Rehabilitation – Eccentric Strengthening

Several researchers have contended the Advantages of eccentric strengthening after an acute hamstring injury versus concentric when aiming to reduce timeframes for return-to-play(1-5,9). The crux of this debate is that together with the vast majority of acute hamstring injuries occurring throughout eccentric loading (terminal swing or stretching), the rehabilitation ‘should reflect the specific situation that lead to the harm"(1). This quote was obtained from a research study, which showed a significant difference between an eccentric and concentric rehabilitation program following severe hamstring injuries in elite and non-elite footballers.

Clinical trial on 75 footballers at Sweden, which noted that using eccentric strengthening versus the time to return-to-play was decreased by 23 days. This was irrespective of the sort of injury or the website of injury. The outcome measure was the amount of days to come back to full– team training and availability of match choice. This article will now research this study in greater depth.

Two rehab protocols were utilized, And initiation began five days after injury. All players had sustained a sprinting-type (top speed jogging/ speed) or stretching-type injury (high kicking, split places, slide handling). Exclusion criteria included previous hamstring injuries, injury to anterior thigh, continuing history of low back problems, and pregnancy.

Evaluation 5 days after the accident, to expose the severity and site of injury. A participant was judged to be fit to return to full-team training using the energetic ‘Askling H-test’ (see below). A positive test is when a participant experiences any insecurity or apprehension when performing the test. The test ought to be completed without full dorsiflexion of the ankle.



Seventy two percent of gamers sustained sprinting-type accidents, whilst 28 percent were stretching-type. Of these, 69\% continuing injury to BFLH, whereas 21\% was located from the SM. Injuries to ST were just continued as secondary injuries (48\% with BFLH, and 44\% with SM). Ninety four percent of sprinting-type injuries were located in the BFLH, while SM was the most common (76\%) location for the stretching-type injury.

The two rehabilitation protocols utilized were labelled L-protocol and the C-protocol. One aimed at loading hamstrings through lengthening (L-protocol), and the other consisted of exercises with no focus on lengthening (C). Each consisted of three exercises that could be carried out anywhere and were not dependent of complex gear. They also geared toward controlling flexibility, trunk/pelvic equilibrium as well as specific strength training to the hamstrings. All were played in the sagittal plane with speed and load improved throughout.


Findings

The Opportunity to reunite was significantly shorter in the L-protocol compared with the C-protocol, averaging 28 times and 51 days respectively. Time to come back was also significantly shorter in the L-protocol than in the C-protocol for injuries of the two sprinting-type and stretching-type, as well as for injuries of different injury classification.

Summary & Clinical Implications

BFLH is involved more often in sprinting-type injuries as a consequence of terminal swing. This is possibly because of its absorption of the most significant summit musculotendon strain across all four hamstring muscles.

Injuries can be classified from Grade I-III or maybe more specifically Grade 1-4 for severity and a-c depending on site of injury. This according to MRI findings. The closer the site of injury is into the proximal hamstring tendon, the longer the recurrence- to-play period. Employing eccentric strengthening exercises in rehabilitation programs will promote a quicker return- to-play.

To enable a thorough rehab procedure, clinicians will need to take into account the first hamstring weakness, Any lack of flexibility, previous hamstring accidents, age, exhaustion, and intensity and strength imbalances between hamstring (eccentric) and quadriceps (concentric) contraction.

Pain in the Quadratus Lumborum Muscle

A majority of the population have at some point experienced low back pain in their lifetimes. Although low back pain is recognized to result from numerous conditions or injuries on the lumbar spine, muscle strains such as a quadratus lumborum muscle strain, are believed to be a leading cause for the recognizable symptoms of pain and discomfort.
The quadratus lumborum muscle is a sizable muscle in the shape of a triangle, located deep on each respective side of the lower back. The role of the wide muscular tissue is to grant mobility to the lumbar spine in sequence for the torso to move laterally from side to side as well as extend and stabilize the lower spine to improve posture. When this muscle is strained or pulled, the symptoms can restrict movement on the lower back and since the muscular tissue is so extensive, recovery from this type of injury usually requires more time and patience to fully heal.

Achilles Tendon Injury

Achilles tendonitis is a medical term used to describe a condition resulting in irritation of the large tendon, the Achilles tendon. Found in the back of the ankle, this condition is recognized as a common cause for injury among athletes. Excessive use of the Achilles tendon results in inflammation together with swelling and pain.
The development of Achilles tendonitis can be associated with two important factors, most frequently among athletes, which are, lack of flexibility and over-pronation. With age, the tendons will begin to lose flexibility, just the same as other tissues in the body. This change causes the tendons to become more rigid and more vulnerable to injury. For some people, the ankle may roll too far downward and inward with each step they take. This is called over-pronation, which places more stress on the tendons and ligaments of the foot, contributing to injury if not corrected.
Achilles tendonitis may also develop from other factors. An increase in an athlete’s …

5 Common Causes for Shoulder Pain

The shoulders are the most mobile joints in the human body. Because the ball of the humerus is designed to be larger than the shoulder socket that holds it, the shoulders need to be supported by muscles, tendons, and ligaments to secure them in a stable or natural position. Since the shoulder can be unstable, it is often a site for many common complications. Below are 5 common causes of shoulder pain and their associated symptoms.
Rotator Cuff Tear
Rotator cuff tears within the shoulder are a very common type of shoulder injury. The rotator cuff consists of a set of four muscles: the supraspinatus, the infraspinatus, the subscapularis, and the teres minor. All of these muscles are attached to the bones of the shoulders by tendons, which purspose is to support, stabilize, and grant the arm movement to move up, down and rotate. The rotator cuff ensures that the arm remains in the shoulder socket. Damage or injury from an accident or gradual wear and tear can result in inflammation to t…
