The research study my group and I examined was titled, “Endurance and Strength Training Effects on Physiological and Muscular Parameters during Prolonged Cycling.” This study done by Hausswirth et. all was published in 2010 in the Journal of Electromyography and Kinesiology.
When performing in a triathlon, which consists of swimming, cycling, and running in a single continuous event, it is generally accepted throughout the exercise science community, that “over performing” during the cycling stage by increasing ones cadence or aerobic power, could hinder the running portion of the triathlon that follows (Hausswirth). In order to help triathletes in avoiding this potential problem, the researchers set the purpose of the experiment as follows:
“The purpose of this experiment is to compare the effects of a regime of maximal strength training in combination with a usual endurance training programme with an endurance only training programme on the physiological and muscular parameters during a 2-hr constant cycling test in well-trained triathletes.” Their hypothesis was that in a 5 week period of training, the changes in the cycling cadence would be lesser in the endurance and strength training group versus the endurance only training group.
The specific parameters in which the researchers observed in this particular study include: Electromyography (EMG) of the Vastus Lateralis (VL) and Rectus Femoris (RF), isometric voluntary contraction values, and cycling cadence.
EMG is the recording of the electrical activity of the muscle. The most accurate type of EMG is an intramuscular EMG. For this type of EMG, a fine needle is inserted into the muscle. This will recorded the electrical activity of that muscle during r...
