Rob breaks down a detailed CSU San Marcos study which characterized upper extremity muscle activation generated by surfers while paddling. The study describes which muscle groups are firing, and their duration, magnitude and timing of activation throughout the stroke at different speeds. The team at CSUSM also measured oxygen consumption, paddling cadence, and surfboard motion. The results of the study provide further evidence towards what efficient and effective paddling is, which muscles to train for different paddling speeds, the intensities at which to train for each scenario, and provides a stepping stone for similar research in the future. Come nerd out with Rob and learn if you are activating the correct muscles at the correct time during your paddling!
