The standard citation style used in exercise science is the style used in the journal Medicine & Science in Sports & Exercise (MSSE). MSEE citation style is based on the NLM (National Library of Medicine) style, which is the option you can choose in citation management software like EndNote.
Some helpful resources for MSSE style are linked below in the MSSE Style Resources section.
In-text citations in MSSE style should be numbered, with the full reference appearing in the reference list:
