Commentary

A physical activity (PA) class is a way to help college students add PA each week, which is thought to improve health and help maintain weight.

Traditional weight training (TWT) is known to improve muscle strength and aerobic capacity, and High Intensity Functional Training® (CF) such as CrossFit provides time efficiency training in both muscle strengthening and aerobic exercise.

Previous studies have compared these in college students.

Outcomes include investigating changes in muscle strength, power, and endurance as well as body composition, and participants will be assigned to TWT (n = 36, age 22.6 ± 4.1 years, 72.2% male) CF (n = 49, age 21.8 ± 3.2 years, 55.1% male) and will meet twice a week for 8 weeks from October 2017 to May 2018 at We will meet.

Baseline and post-test measurements include vertical jump, grip strength, 2-minute push-up test, 1-min squat test, height, weight, and bioelectrical impedance analysis.

These analyses did not reveal any significant group x time interactions, but there were significant differences in push-up and squat times.

Participants enjoyed the classes, and both classes improved muscular endurance, but there were no significant differences between groups.
