Table 1. Characteristics of the three study populations used in analyses.
Table 1 represents the demographics for the AHMS participants highlighted in the analyses in Celebrating Heart Month: Updated Trends in Activity and Cardio Fitness. The cohorts were narrowed as data requirements tightened to allow for evaluating different trends in data and to include as many participants as possible for each. Each analysis had different data requirements, resulting in the generation of three cohorts. Cohort 1 is the most expansive cohort, including every participant in AHMS who completed the common demographics survey, reported their assigned sex at birth as male or female, had at least 6 weeks of activity logged passively through Apple Watch and actively logged at least one workout in 2023. Cohort 2 is a subset of Cohort 1 who also had 10 or more VO2 max samples collected in 2023. Cohort 3 is a subset of Cohort 2 who had at least two VO2 max samples collected in January-February and November-December of 2023. The MacArthur Scale of Subjective Social Status survey responses were used to classify subjective social status. The BMI categories were defined based on the BMI classification from the Center for Disease Control and Prevention.
Table 2. Meeting aerobic criteria stratified by age and assigned sex at birth.
Table 2 represents the number and percentages of participants in Cohort 1 meeting the 150 minutes of aerobic criteria on average, stratified by age and assigned sex at birth.
Table 3. Meeting aerobic criteria stratified by race/ethnicity.
Table 3 represents the number and percentages of participants in Cohort 1 meeting the 150 minutes of aerobic criteria on average, stratified by race/ethnicity.
Table 4. Meeting aerobic criteria stratified by state/district/territory.
Table 4 represents the number and percentages of participants in Cohort 1 meeting the 150 minutes of aerobic criteria on average, stratified by state, district, and territory. Both the unadjusted number and percentage and age adjusted percentage are shown. The adjusted percentage for each state is mapped onto Figure 2. Total numbers are not calculated for any location with less than 100 participants represented.
Table 5. Meeting both aerobic criteria and aerobic plus two strength criteria stratified by age.
Table 5 represents the number and percentages of participants in Cohort #1 meeting the 150 minutes of aerobic criteria on average and meeting the 150 minutes of aerobic criteria in addition to two or more strength workouts on average, stratified by age. The data presented in this table is used in Figure 3.

Table 6 shows the demographics for the AHMS participants in Cohort 2 stratified by the cardio fitness categories above average/high and below average/low calculated using their averaged VO2 max values for the 2023 year.
Table 7 Percentage of workouts started by hour of the day stratified by cardio fitness levels.
Table 7 represents the percentages of workouts started by hour of the day in Cohort 2, stratified by cardio fitness level. The data presented in this table is used in Figure 5.
Table 8 Percentage of workouts started by time of day stratified by cardio fitness level.
