This is the Zumba research results done by the American Council on exercise (ACE). Very good results. Zumba is a great workout for any student because it allows you to modify to your needs but it still gives you the recommended benefits no matter the fitness level you have. Everyone benefits form it. Read below and see for Yourself. READ IT!!!!!! Never take things for truth unless you read about it o in a good research The Study Led by Porcari and Mary Luettgen, M.S., researchers from the University’s Department of Exercise and Sport Science set out to determine the average exercise intensity and energy expenditure during a typical Zumba fitness class. First they recruited 19 healthy female volunteers, ages 18 to 22, all of whom had previous experience participating in Zumba classes. To establish a baseline of fitness for the study subjects, each performed a maximal treadmill test that measured heart rate (HR) and oxygen consumption V•O2. This test also enabled researchers to develop individual linear regression equations for each subject to predict their V•O2 based on HR readings. This was key because standard metabolic testing gear is bulky and wearing it would encumber the subjects’ ability to dance and properly participate in the Zumba class. After the treadmill testing, each subject participated in a single Zumba session while equipped with a heart-rate monitor. While the class length varied from 32 to 52 minutes depending on which day it was conducted, the same Zumba-certified instructor taught all of the sessions. The fitness craze now known as Zumba is said to have started as a mistake by Colombian fitness trainer Alberto “Beto” Perez. One day in the mid-90s, Beto reportedly forgot to bring his regular aerobics-style music tape to the group exercise class he was leading. With no music and a class to teach, he raced back to his car and scrounged up a cassette tape of Latin dance music. As the lively beats of Merengue and Rumba rang out, Beto drew upon his experience dancing in Salsa clubs and choreographing for local artists. Soon he was leading his pupils through a fun series of dance steps—and Rumbacize was born. It was an instant hit, and quickly became the most popular class at his gym. In 1999, Beto brought Rumbacize with him when he moved to Miami. It immediately caught on there as well and, with the help of a pair of entrepreneurs, Beto rebranded his class and transformed it into the global franchise that is Zumba today. The Results After crunching the resulting data, researchers found that participating in a single Zumba fitness class burned an average of 369 calories or about 9.5 kcal per minute (Table 1). The average HR was 154 beats per minute (bpm), which is roughly 80 percent of the average predicted HRmax for the subjects (Figure 1). Accepted fitness industry guidelines suggest exercising in the range of 64 percent to 94 percent of HRmax to improve cardio endurance, so Zumba meets those requirements. “If we look at the heart-rate monitor strips from the Zumba session, they kind of look like interval workouts, going back and forth between high intensity and low intensity,” says lead researcher Mary Luettgen, M.S. “Because of that, with Zumba you burn a lot of extra calories compared to a steadystate exercise like jogging.” As for the average estimated percentage of V•O2max, the subjects averaged 64 percent of V•O2max, which is well within industry recommendations of 40 percent to 85 percent of V•O2max for improving cardio endurance. Of particular note is that HRmax and V•O2max responses for all of the subjects fell within the range of industry guidelines, despite the fact that there was a wide range of fitness levels among the subjects. FATHER ZUMBA 3 | September 2012 • ACE CertifiedNews The Bottom Line Zumba may feel like a party, but this research suggests that it’s also a highly effective workout. “It’s a total-body exercise—a good, high-energy aerobic workout,” explains Dr. Porcari. “Zumba is also good for core strengthening and flexibility gains because there are lots of hip and midsection movements.” With subjects burning an average of 369 calories per class, Zumba is also a fine choice for those who are looking to drop a few pounds or maintain their current weight levels. In comparison with other exercises tested in the past by the University’s Department of Exercise and Sport Science, Zumba burns more calories than cardio kickboxing, step aerobics, hooping and power yoga (Figure 2). “The surprising thing is that it doesn’t matter what fitness level you’re at—our research shows that with Zumba everyone is working out at the zone that’s recommended for improving cardio health,” says Luettgen. “Both fit people and less-fit people are going to get an equally good workout.” Bottom line, Zumba is an effective interval-style, fullbody workout with built-in variety because every class and every instructor is slightly different. Equally important is the notion that Zumba is entertaining, which means exercisers are busy burning calories and getting fit while enjoying the fun of Latin dancing. Sounds like our kind of party. ACE recommends that, before engaging in any exercise regimen for the first time, individuals consult with their doctors. This study was funded solely by a grant from the American Council on Exercise (ACE).
