TWT is a popular form of exercise recommended for many different populations that has been widely examined in the literature and is commonly offered as an activity class for college students. The benefits of traditional weight training (TWT), or the practice of movement under load with a weighted object, are widely understood and accepted by a variety of health professionals and include improvements in muscular strength, power, hypertrophy, and muscular endurance as well as neuromuscular adaptations. Įnrolling in activity classes such as weight training helps college students add scheduled PA into their week.
Even more concerning is that weight gain significantly increases across students’ time in college and weight trajectories during adolescence persist into adulthood. This is reflected by a period of weight gain during the freshman year where the majority of students (60.9%) gain an average of 3.38 kg. The transition to college includes many social forces that can negatively impact students’ nutrition, drinking, and PA habits. Recent data from the American College Health Association (ACHA) indicate 37.7% of college students are overweight or obese. adults are overweight or obese and obesity has increased dramatically among young adults aged 18–29. Nationally, more than two thirds (70.7%) of U.S. Examining PA classes designed for college students is relevant and may assist in determining the best types of classes to offer to improve health, prevent weight gain, and increase adherence in college students. Although most universities offer a variety of PA options, nearly a quarter (22.4%) of students do not engage in regular PA and gain significantly more weight than their age-matched peers that do not attend college or university. PA can aid in maintaining body weight and helps improve cognition across the lifespan. People who are physically active tend to live longer and have a lower risk for heart disease, a stroke, type 2 diabetes, depression, and even a few cancers. The United States Department of Health and Human Services (USDHHS) recommends individuals engage weekly in moderate to vigorous aerobic physical activity (PA) as well as muscle strengthening activities. Future research should examine the benefits from longer or more frequent classes. Activity classes provide college students with an option for increasing their weekly PA and help maintain body composition. Both classes improved muscular endurance although no significant differences were found between them. Participants enjoyed the classes and most planned to continue. Although no significant group × time interactions were found, there was a significant main effect of time for push-ups and squats (both p < 0.001). Baseline and posttest measurements included a vertical jump, grip strength, a 2 min push-up test, a 1 min squat test, height, weight, and a bioelectrical impedance analysis. Participants were 85 healthy college students enrolled in TWT ( n = 36, age 22.6 ± 4.1 years, 72.2% male) or CF ( n = 49, age 21.8 ± 3.2 years, 55.1% male) classes meeting twice/wk for 8 weeks between October 2017 and May 2018. We examined changes in muscular strength, power, and endurance as well as body composition. Limited research has compared these classes for college students. High-intensity functional training such as CrossFit ® (CF) provides time-efficient workouts with both muscle strengthening and aerobic exercises. Traditional weight training (TWT) can improve strength and aerobic capacity. Physical activity (PA) classes help college students add weekly PA, which can help improve health and maintain body weight.
