Strength Development

in Cyclists

What exercises or drills can I do?

What can I do?

Cycling Performance: Contributing Elements

Performance Improvement: Making it Possible

• Choosing correct amount of each individual training

element

• Integrating elements appropriately throughout the

day, week, month, year

• Appropriate progression of training volume,

intensity and complexity

• Proper insertion of rest and recovery

• Execution of work with optimal mechanics

Development Priorities

Al Vermeil’s Pyramid of Athletic Development

Modular Development Pyramid – D.Hansen

Cycling Research – Strength Training Effects

• Zoladz et al. 2012 – Isometric strength training

lowers 02 cost of cycling during moderate-intensity

exercise

• Untrained young men increased force during MVC

of knee extensor muscles over 7 weeks by 19%

• Compatible with the increased running economy

and cycling efficiency observed after strength

training in endurance athletes

Cycling Research – Optimizing Strength Training

• Ronnestad and Mujika, 2014 – Combining endurance

training with heavy or explosive strength training for

endurance athletes

• Heavy strength training favored for improving cycling

economy

• Explosive training and heavy strength training better for

endurance runners

• Mechanisms for improvement:

• Improved neuromuscular efficiency

• Fibre conversion – 2X to 2A fibres (more fatigue resistant)

• Improved musculo-tendinous stiffness

• Potential negative outcomes – muscle hypertrophy

Cycling Research – Optimizing Strength Training

• Ronnestad and Mujika, 2014

Cycling Research – Strength Training Improves Economy

• Sunde et al., 2010 – Improvement in CE without any

decline in maximal oxygen consumptions

• Maximal strength training improves time to exhaustion at

maximal aerobic power

• A 5% improvement in CE could account for a 5%

improvement in time performance over distance

• Suggest a protocol of 4 x 4RM for two to three times per

week using half-squats

Cycling Research – Strength Training Improves Economy

• Sunde et al., 2010

Cycling Research – Strength Training and Pedal Rate

• Hansen et al., 2007 – Strength training reduces freely

chosen pedal rate during sub-maximal cycling

• It has been suggested that subjects pedal fast to reduce the

perception of force

• Training group increased strength over 12 weeks by 20% in

squat and 12 in leg curl exercises

• Freely chosen pedal rate was reduced by 8 and 10 rpm

during cycling at 37% and 57% of max power output

• Accompanied by a 3% lower rate of energy expenditure

Cycling Research – Strength Training and Pedal Rate

• Hansen et al., 2007

Cycling Research – Muscle Coordination Patterns

• Blake et al. 2012 – examined surface EMG,

kinematics and pedal forces at various level of

VO2max

• Found that at 55-60% of VO2max, mechanical

efficiency was maximized and highly related to

muscle coordination patterns

• High efficiency cycling had:

• More gastroc and soleus

• Less glute, quad and tibialis anterior

• Later lower quad and biceps femoris

• Earlier semintendinosus

• Greater foot plantar-flexion on downtroke and greater

dorsi-flexion on upstroke

Cycling Research – Core Strength and Fatigue

• Abt et al. 2007 – Looked at core stability fatigue

and impact on cycling mechanics

• Pre-fatigued subjects with core exercises, then

tested them on cycling treadmill

• Cycling kinematics changed but pedal forces

through cranks did not

• Body compensates to maintain pedal forces by

changing cycling kinematics in conditions of core

muscle fatigue

• Implications for chronic injury

Where Do We Go From Here?

• Strength training for cyclists – of all types and

distances – is useful

• How do we make sure we do it right?

• Who do we trust?

• Strength must be a means to and end, not an end in

itself

How Strong is ‘Strong Enough’?

The Issue of Specificity

• Cycling is the best thing you can do for training

• Strength training must be done in parallel with cycling

training (coordination and transfer)

• Cycling training can be arranged to elicit strength

benefits:

• Speed Training - max effort for 15 sec or less (force development,

CNS enhancement)

• Hill training – short hills (strength and anaerobic power)

• Hill training – long hills (strength endurance and aerobic power)

The Issue of Specificity

Implications for Training – Speed Reserve

Choosing Strength Training Exercises

• Weight training must be maintained as a “general”

strength input and not be too specific

Training with Weights – Issues to Explore

• Free weights vs machines

• High reps vs low reps

• Heavy weight vs low to moderate weight

• Olympic lifting vs simple exercises

• Bilateral vs unilateral exercises

• Alternatives to weightlifting

•Free Weights vs Machines

• Free weights simulate ‘natural’ movement patterns

• Free weights require more instruction and supervision

• Machines – taking the coordination component out of

lifting to free up the CNS

• Combining the two methods – best of both worlds

High reps/Low Load vs Low Reps/High Load

• High load – improved muscle fibre recruitment

• Greater recovery between sets required

• Low dosages of heavy weight at low reps go a long

way

• High reps and low loads are still useful for developing

work capacity, strength endurance and connective

tissue strength

• But the weight room should not be a place for training

endurance

Olympic Weightlifting vs Simple Exercises

• Highly dependent on equipment and coaching

availability

• Olympic weightlifting has components of maximal

strength and power

• Maximal strength can still be developed through

squatting, dead-lifts and step-ups

• Velocity and power can be achieved through other

means (jumps, plyometrics, med-ball throws)

Bilateral vs Unilateral

• Bilateral – higher loads, greater activation and

recruitment

• Unilateral – greater stability requirement, lower

loads, perception of specificity

• Integrate both modes as part of your training

• Ordering in a session: Higher loads early, lower

loads later

Alternative Methods

• Resistance bands

• Medicine ball

• Jumps and plyometrics

• Electrical muscle stimulation

Resistance Bands

• Commonly used for joint rehab and injury

prevention

• Light to moderate resistance

• Concern – opposite to normal force-velocity curve

(easier over short ROM, harder at greater ROM)

Resistance Bands

Medicine Balls

• Explosive throws – 4-10 reps – for maximal

recruitment and power

• Circuit throws – 10 reps and up – for general

strength

• Lower time under tension, higher velocities

• Athletes report feeling lighter and more responsive

as compared with weight training

Medicine Balls – Explosive Throws

Jumps and Plyometrics

• High velocity body weight movements that require

more forceful muscle recruitment

• Can build concentric, eccentric and elastic strength

• Effective at increasing performance, but can be

higher risk in terms of acute and chronic injuries

(i.e. tendon injury)

Planning and Integration of Work

• 2-3 sessions per week should be adequate

• 3 sessions per week – off-season

• 1-2 sessions per week – in-season

• Emphasis on quality of work and intensity, not

volume

The Value of High Intensity
