Abbreviation	Term	Brief explanation
BMI	Body Mass Index	BMI = kg/m2 where kg is a person's weight in kilograms and m2 is their height in meters squared
eQTL	Expressed quantitative loci	Genomic loci (with DNA sequence/nucleotide variants) that explain variation in expression levels of mRNAs
GEO	Gene Expression Omnibus	International public repository that archives and freely distributes high-throughput gene expression and other functional genomics data sets
	Genome	All genetic information of an organism
GWAS	Genome-wide association studies	Observational studies of a genome-wide set of genetic variants (normally SNPs) in different individuals to see if any variant is associated with a trait
GTEx portal	Genotype-Tissue Expression portal	A public database of identified genetic variants (eQTL) that influence how genes are turned on and off in human tissues and organs
IPA	Ingenuity Pathway Analysis	Commercial web-based software application for pathway analysis using a manually curated knowledge base
PCA	principal component analysis	A statistical procedure that allows you to summarize the information content in large data tables by means of a smaller set of “summary indices” that can be more easily visualized and analyzed
RM	Repetition Maximum	The most weight that can be lifted for a defined number of exercise movements
RET	Resistance-Exercise Training	Exercise that causes the muscles to contract against an external resistance with the expectation of increases in strength, power, hypertrophy, and/or endurance
RT-PCR	Reverse transcription Polymerase Chain Reaction (PCR)	Laboratory technique combining reverse transcription of RNA into complementary DNA (cDNA) and amplification of specific DNA targets using PCR. Primarily used to measure amounts of specific RNAs
SNPs	Single Nucleotide Polymorphisms	Single nucleotide variants at specific positions in the genome
	Transcriptome	The set of all RNA transcripts, including coding and non-coding, in an individual or a population of cells
