On different days, the athletes completed 6\u2009\u00d7\u20093\u00a0min rounds of pad, bag or spar-based training with 1\u00a0min recovery between each round. Prior to each session, participants put on a heart rate monitor and near-infrared spectroscopy attached to the belly of the rectus femoris muscle to record heart rate and muscle oxygenation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      There were significantly less punches thrown in sparring compared to other training modalities (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001). Skeletal muscle oxygenation across training modalities consisted of a delay, fast desaturation and steady state. Across rounds there was a significant increase in time delay for desaturation (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.016), rate of fast desaturation (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001) and duration of fast desaturation (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.019). There was a significant difference in sparring for the heart rate where skeletal muscle oxygenation changes occurred compared to pads or bag sessions (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The findings highlight differences in the skeletal muscle response to the different training modalities.
