For recreational runners and cyclists, strength training is not always considered important when developing increased pace, endurance and mechanics. But this paper from 3 years supports the involvement of explosive strength training as part of a training program for endurance runners/cyclists. With benefits of improved endurance to muscle fibres when in an anaerobic state, increased tendon stiffness and greater explosive power.

The study went on to find numerous benefits with the addition of strength training. And provided these recommendations.

  1. To improve the chance of increased endurance performance following a strength training program, the resisted exercises should engage similar muscle groups and imitate sport specific movements. This will result in firing up the same neural pathways connected with the motion of running or cycling.
  2. Force output may increase the ground strike in runners or force velocity in cycling if an explosive focus is put on the concentric phase of the muscle. For example pushing fast out of the back squat.
  3. At least 2 sessions per week of strength training to develop maximal strength over a 12 week program. Beginning with lighter loads in the first 3 weeks to learn correct form before increasing load. Working within 8-12 reps and 2-3 sets.

Some beneficial lifts for runners and cyclists would include back squats, dead lifts, hip thrusters and bent over rows.

Abstract

Here we report on the effect of combining endurance training with heavy or explosive strength training on endurance performance in endurance-trained runners and cyclists. Running economy is improved by performing combined endurance training with either heavy or explosive strength training. However, heavy strength training is recommended for improving cycling economy. Equivocal findings exist regarding the effects on power output or velocity at the lactate threshold. Concurrent endurance and heavy strength training can increase running speed and power output at VO2max (Vmax and Wmax , respectively) or time to exhaustion at Vmax and Wmax . Combining endurance training with either explosive or heavy strength training can improve running performance, while there is most compelling evidence of an additive effect on cycling performance when heavy strength training is used. It is suggested that the improved endurance performance may relate to delayed activation of less efficient type II fibers, improved neuromuscular efficiency, conversion of fast-twitch type IIX fibers into more fatigue-resistant type IIA fibers, or improved musculo-tendinous stiffness.
