Groin injury rehab using the MyoThrusta – a case study from rugby

Groin injuries are a common and frustrating problem for rugby players, frequently involving extended periods out of the game followed by further time in getting back to full match fitness. The MyoQuip MyoThrusta offers the prospect of accelerated recovery of functionality and strength while the body is repairing. The MyoThrusta is a unique type of leg press which combines a supine body position with accommodating resistance giving the exerciser effective loading and muscle fibre recruitment through the whole range of movement. Intensive use of this apparatus enabled Sam Jeffries to get back on the playing field in time to be selected in the Australian Under 20 Squad which is about to travel to South Africa for the World Championships

Sam Jeffries moved from Brisbane prior to the 2011 season to join the Sydney University Rugby Club. During that season he missed the majority of matches due to groin pain and then had to have shoulder surgery last October. This combination of injured areas would have made it extremely difficult to do off-season strength training using conventional exercises. Staff from Sydney University’s Physical Preparation Department and Sports Clinic combined to develop an integrated rehab strategy focussed on the MyoThrusta, Physiotherapist Elias Boukarim explained:

Is Jerry Yanuyanutawa the most powerful prop in world rugby?

This video shows Jerry Yanuyanutawa, Fijian-born Sydney University front rower, box-squatting 260kg for 6 reps at the University gym in September 2008.

Prior to 2007, Jerry had been a back rower, but changed to the front row under the tutelage of Trevor Woodman, England World Cup winning front rower and Sydney University scrum coach. For most of that season Jerry played Third Grade but was elevated to the Firsts by Woodman for the Sydney Premiership Grand Final won by University 34-11.

In 2008 he was the only non- Super 14 contracted player to make the Australia A squad for the Pacific Nations Cup. Also, during the Club Premiership season he scored 12 tries including one in the Grand Final again won by University 45-20. A highlight of that game was the dominance of the University front row comprising Yanuyanutawa, Nathan Charles and Laurie Weeks.

The video was shot during the week after that Grand Final, clear evidence that max strength work can be continued throughout the playing season.

So where does Jerry Yanuyanutawa rate among the strong men of rugby?

When the most powerful props in the world are discussed two names that invariably crop up are England’s Andrew Sheridan and New Zealand’s Carl Hayman. Both are credited with a 275kg squat, presumably for one rep. More recently Ben and Owen Franks, Crusaders and All Blacks props, have been mentioned as contenders for the title of world’s strongest rugby player. The All Blacks web site quotes scrum guru Mike Cron saying, “I was told yesterday they were doing about a 240kg squat.” But all of this is anecdotal with no actual evidence.

However, on July 8, 2007, a video titled “NZAllblacks in the Weight-room” was posted on YouTube. The description read: “Pushing Tin: Join the All Blacks in a gym workout and watch big Carl Hayman squat a personal best 220kg.” Hayman is shown box-squatting 220kg for three reps spotted by strength coach Ashley Jones.

According to the National Strength and Conditioning Association (NSCA) Coefficients used to determine 1RM, a squat set involving 3 reps at 220 equates to a single rep of 249kg.

By the same measure Jerry Yanuyanutawa’s 6 reps with 260 equates to a single rep of 323kg! This means that Yanayanatawa's squat set would rate 30% heavier than Hayman's effort, although of course relative box heights need to be taken into account.

Tim Leahy, Jerry's strength coach at Sydney University, had long recognised that his player had freakish physical capacities. "It was just a matter of getting him to apply himself and stay focussed."

Fortunately throughout 2008 he responded to the challenge with Tim Leahy spending many hours one-on-one with his young charge; "The key to getting the best out of Jerry was to constantly vary his training tasks and to continually challenge him.”

“Jerry is a very gifted guy athletically with great genetics and an abundance of fast twitch fibre. Along with the then SUFC forwards coach and former English World Cup winning front rower Trevor Woodman the major focus we had for Jerry was to build a base of strength and power that would be a benchmark for front rowers worldwide.”

Significantly Yanuyanutawa’s max strength program involved quite limited actual squatting, with greater focus being placed on the Romanian deadlift and MyoTruk and MyoThrusta apparatus.

Making full use of his Melanesian genetic endowment Jerry Yanuyanutawa was able to record some outstanding speed and power numbers to match up with his prodigious efforts under the squat bar. As Tim Leahy notes, “During the actual playing season he was able to post best times of 1.71s and 5.38s for the 10 and 40 metres, as well as a vertical jump of 76cm. With a peak power output of nearly 9000 Watts, there is a lot of power that can be used at scrum time and during the collision.”

Jerry became something of a cult figure in Sydney club rugby with his barnstorming runs producing most of his 12 tries in 2008. As he says, “I like to get the ball in my hands and run. If there’s an opportunity to score a 20-metre try then I’ll back myself. Fijians are known for throwing the ball around a bit and I like that too. But I’m also learning the technical side with scrummaging and lifting [in lineouts] and learning to play within that team structure, but when I get out there I like to unleash and show what I’ve got.

“I do thrive in loose play and love to get my hands on the ball and run with it.” However, front rowers are never permitted to get too far away from their basic craft. “Trevor Woodman said to me none of that counts if you can’t scrummage or lift.”

Jerry’s first two seasons with the CA Brumbies were disrupted by injuries, but he is focussed on cementing a run-on spot for next year’s Super 15 season.

Jerry Yanuyanutawa, rugby front rower, box-squatting 260kg for 6 reps

This video was shot in the week after that Grand Final. Right throughout the season Jerry's strength coach, Tim Leahy, had kept Jerry on a max strength program, although the amount of squatting was limited. Instead the lower body strength work was focussed on the MyoQuip MyoTruk and MyoThrusta apparatus together with the deadlift.

Fast-tracking the development of young rugby players in the four "esses" - size, strength, speed and skill

A two-year program of accelerating the physical and skill development of young players at Sydney University has returned big dividends.

Within days of losing the 2006 First Colts Grand Final due to being out-muscled at the breakdown, University coach Nick Ryan met with his team and together they made a pact to never again be pushed off the ball. The players allowed themselves a mere three weeks break before getting back into training for the 2007 season at a level of intensity not seen before in Sydney club rugby. The off-season training regimen consisted of 4 weights sessions and 3 field sessions per week, switching to 3 weights and 2 to 3 field sessions during the playing season plus regular individual video analysis and field sessions with the coach.

The central ingredient of the training has been the strength and conditioning components devised by Martin Harland and administered by him and his assistant, Tim Leahy. "I guess we have two training tenets" Harland explains, "that is to always train hard and to train hard in the right areas. Thus developing the culture of no short cuts and to attend to the things in a prioritized plan from what we lack the most or what will help us the most on the park." Harland's programs for rugby players place a high degree of emphasis on basic strength development, increased bodyweight and speed. At the same time, given the year-round training commitment, great care is taken to guard against player burnout.
"We are consistently monitoring signs of overtraining," says Leahy. "Our in-season training structure does differ from our pre-season regime. The two key factors that help us guard against overtraining and player burnout is to firstly ensure our players are educated and understand the importance of post-game recovery strategies. "Secondly a close working relationship with coaching staff to ensure on field and gym volumes are of an optimal load. All variables as well as player’s subjective observation of energy, fatigue levels and contra indicators to injury are taken into account when prescribing volumes."

With a strong strength and fitness foundation laid, Nick Ryan and his team coaches are free to focus on technical proficiency and team cohesion. "The aim of our training sessions," says Ryan, "is to up-skill and empower the players, so that when they take the field not only can they read the game and make the right decisions, but then execute and finish off the activity with the help of team mates who are on a similar skill level and wave length." The payoff in terms of enhanced performance from the integration of strength and rugby coaching has been dramatic.

In the 2007 season University First Colts lost just one game out of 25 in winning both Minor and Major Premierships. Seconds and Under-19 Colts also won both Minor and Major awards. The dramatic improvement in the physical development of players can be seen from the Table below. As compared with the 2006 First Colts team, the 2007 forward pack's average bodyweight increased 5kg to 104.3kg; the backs 5.8kg to 86.2kg; and the team as a whole 5.3kg to 95.8kg.

The second year of intensive training produced even more impressive results. In the 2008 season all three Colts grades won both Minor and Major Premierships, with First Colts remaining undefeated throughout their 24-game season. Despite the age limit for Colts having dropped from Under-21 to Under-20, players' bodyweights again increased by 0.2kg for the forwards; 2.8kg for the backs; and 1.5kg overall.

"physical domination ... has enabled us to build a very strong defensive wall and to implement a highly structured game plan which we can maintain for the full 80 minutes."

To put the 2008 figures in perspective the Table also shows the bodyweights of the best professional rugby players in Australia, the current Wallabies squad. They outweigh this club-level Under-20 team by just 6kg per man in the forwards and 4.4kg in the backs. And this team of university students is currently on an unbroken 34-game winning streak! It is almost time for the administrators of Australian rugby to recognise and to take seriously the great experiment that is going on in their own backyard.

Colts coach Nick Ryan has the extraordinary record of taking his team to the Grand Final in each of the 7 years he has coached; with his only loss the 4 point defeat in 2006. He says, " A very important outcome from the intensive training regime of the past 2 years has been our ability to achieve physical domination in matches. This has enabled us to build a very strong defensive wall and to implement a highly structured game plan which we can maintain for the full 80 minutes." As with the weight training, Ryan ensures that the field sessions are short and frequently varied, with the emphasis on having his team peak on Grand Final day in September. He certainly achieved this in 2008 with the winning scoreline 39-5.

In the regular season in 2008 Ryan's team averaged a 40-point winning margin and conceded only 8 points per game. Seconds and Thirds Colts also conceded just 8 and 5 points respectively per game.

A distinctive feature of the Sydney University rugby program has been its reliance on the MyoQuip range of strength building equipment. For the past four years the University gymnasium has been the primary development site for these machines. Not surprisingly MyoQuip's ScrumTruk and Hipnee Thrust* have been extensively used for lower body strength development. Martin Harland says, "These two lower limb extensor machines have been integral to training a wide cross-section of athletes in different sports at the University. In rugby they enable us to reduce the deleterious effects of heavy lower leg extensor exercises and on-field running loads. Traditional heavy squats & deadlifts are great for strength and size but are only moderately compatible with higher running loads for field or court sports. and incompatible with a sizeable subset of your player population for various reasons. To be able to de-load players spines while building hip & knee extensor strength through range of motion means more athletes able to train intensely in the gym and front up for intense speed & fitness work in the same week.” "

The combination of an intensive, well-structured and coordinated training regimen and the use of strength apparatus with high specificity for rugby can be seen to have produced accelerated physical development which has enabled players to perform at a consistently high standard.

*In recent months the University gymnasium has replaced its ScrumTruk and HipneeThrust machines with the more advanced and compact MyoTruk and MyoThrusta models.
