A speedometer and video\n                    footage were used to assess the pullout phase kinematics and the total\n                    underwater sequence. Dryland assessments included the maximum jump height, the\n                    isometric peak strength of internal shoulder rotation (IR) (at 90\u00b0), and knee\n                    extensors (at 60\u00b0). The joint ROM of knee flexion (KF), plantar flexion (PF),\n                    and hip internal rotation were also considered. Velocity\u2013time curves of both\n                    techniques according to sex were dissected using statistical parametric mapping.\n                    An independent t-test was used to compare differences between swimmers\u2019\n                    sex in kinematic and dryland variables while the Pearson correlation coefficient\n                        (r) was used for associations. Higher instantaneous velocity at\n                    ~24\u201326, ~31\u201342, and 54.5\u201363% during the glide phase duration was found for males\n                    in the Fly-Kick first technique. Males also displayed a higher peak (3.29\n                        m\u00b7s\u22121) and mean velocity (1.58\u20131.65 m\u00b7s\u22121) in the\n                    total underwater path or in the glide and propulsion phases of both pullout\n                    techniques. While males performed better in jump height (33.89 cm) and peak\n                    strength of IR (172\u2013176 N), females showed a higher ROM mostly in PF (161\u2013165\u00b0).\n                    A high and positive correlation between dryland strength and kinematics in both\n                    pullout techniques was found in males. The ROM failed to correlate with pullout\n                    kinematics, except for the KF in females during the recovery phase\n                    (r=0.82\u20130.86). In conclusion, male breaststrokers perform better than\n                    females on dryland strength but not in joint ROM, which provides them with an\n                    advantage mainly in the Fly-Kick first underwater pullout.<\/jats:p>","DOI":"10.1055\/a-2625-4264","type":"journal-article","created":{"date-parts":[[2025,6,26]],"date-time":"2025-06-26T18:45:51Z","timestamp":1750963551000},"page":"973-981","source":"Crossref","is-referenced-by-count":0,"title":["Relationship
