Application of Sports Science in English Professional Rugby League:
Practical Considerations in Strength & Conditioning. International Journal of
Sports Science & Coaching Vol 7 (1) pp 33 – 44

Step One: Analysis of the Sports Performance
Step Two: Needs Analysis of the Team / Individual
Step Three: Design of the Intervention
Step Four: Implementing the Intervention
Step Five: Monitoring the Intervention and Promoting Adherence
Step Six: Evaluating the Intervention – Programme Modifications and
Analysis
Step Seven: Exiting the Intervention


Step One - Needs Analysis (Sport)
• The physiological demands of Rugby League are complex, requiring players to
have highly developed speed, agility, muscular strength & power and maximal
aerobic power (1)
• Body mass and excess body fat have been shown to have a negative effect on
sporting performance (2)
• Body fat for forwards and backs is reported to be similar (Forwards
15.6%, Backs 12.6%) (2)
• VO2 max has been reported in the range of 48.6 - 56.4ml.kg.min (3)
• A definite need to move quickly to position themselves for attack and defence
(2)
• Players rarely sprint distances >40m in a single bout (2)
• No significant differences have been observed between forwards and backs for
10m speed, Backs are consistently faster over 40m than forwards (4)
• The mean 10m & 40m times for professional rugby league players is in the
range of 1.71 – 1.83 and 5.08 – 5.66 seconds, respectively (5)


• Given the highly intense, intermittent nature of Rugby League, repeated sprint
ability is extremely important (1)
• A time motion analysis highlighted forwards spending 16.5% of game time in
high intensity exercise compared to 17% for backs (6)
• This study reported every 4secs of high intensity exercise was followed by
approximately 21s of low intensity exercise (6)
• Rugby League players require the ability to rapidly accelerate, decelerate and
change direction (1)
• Players are required to have high levels of strength in order to effectively
tackle, lift, push and pull opponents during a match (1)
• Meir reported significant differences in 1RM squat between forwards and backs
(188 v 168kg) and bench press (119 v 113kg) (7)
• Greater strength in professional rugby league players has been attributed to
neural adaptations that occurs with long term periodized strength and power
training (1)


• Superior playing performance of elite level players is often attributed to greater
physiological capabilities (8)
• Players also require the ability to constantly execute complex skills under
pressure and while fatigued (9)
• The significance of high physical fitness levels are reduced if the physiological
parameter does not transfer to improved playing performance (10)


Step Two - Needs Analysis (Athlete)
Athlete Description
• Rugby League (Hooker)
• 18 Years
• Age Grade Elite Standard
• Injury Status: No recent or relevant injuries
• Training Status: Three years within RL Academy setting. Sound knowledge of
basic principles and strength training application. Olympic lift and derivatives
limited (developed during season).
• Personal Goals for Season:
Increase muscle mass
Increase 1RM scores for Bench Press & Squat
Improve 5 & 10m acceleration time
• Team / Coaches Goals for the Season:
Increase of lean mass
Increase speed scores across the board
Increase strength scores (end of season) by 20%

Step Three - Design
• Training variation is increasingly acknowledged as serving a key function in
successful training prescriptions (11)
• Periodization offers a framework for planned and systematic variation of training
parameters, in a way that directs physiological adaptations on the training goals
required for the sport (12)
• Periodized training offers superior development of strength, power, body
composition and other performance variables (13)
• A major obstacle for coaches working in seasonal team sports is the frequent
matches and extended competition period (11)
• Team sports using the classic model would taper considerably for the duration of
the competition phase which is clearly counter productive (14)
• Coaches must take into account the interaction of metabolic conditioning that is
performed alongside strength and power training (15)
• It has been suggested that undulating nonlinear periodized approaches are more
viable when planning the training year for team sports (16)


Step Three – Design (Macro Cycle)
It is the merging of science and sweat that will allow athletes to excel (17)

• Block One – Hypertrophy (German Volume Training)
• Block Two – Strength (22)
• Block Three – Strength Speed (20)
• Block Four – Speed Strength (22)
