“…The more experienced group (>20 classes experience) reported significantly higher relative energy expenditure, predicted maximal heart rate, and sweat rate compared to the novice group (<20 classes experience). These findings are supported by similar trends in unpublished data presented at the 2013 Rocky Mountain ACSM Annual Meeting; however, the unpublished data reports higher values for energy expenditure and average intensity (333–459 kcals, 3.7 METS) over the whole class in experienced practitioners (>12 months experience, n = 19) [ 29 ]. Based on this acute data, and although it appears that Bikram yoga elicits a greater average in-session MET level compared to other forms of hatha yoga [ 30 , 31 ], the prescribed 8-week interventions in the studies reviewed may be insufficient for weight loss considering that ACSM recommends building up to 250–300 minutes of moderate intensity aerobic exercise per week for weight loss and maintenance of long term weight loss [ 32 ].…”

“…Research that has reported increased aerobic capacity after an 8-week Bikram yoga trial used a predictive VO 2max measure (1-mile walk), which is not as reliable as an actual VO 2max test. In-session VO 2 data shows that the average intensity of a Bikram yoga session is light to moderate [ 28 , 29 ], suggesting that the cardiovascular adaptation may be great enough to improve VO 2max in certain cohorts such as populations suffering from reduced cardiorespiratory fitness (e.g., sedentary individuals, asthmatics, and older adults), which is significant, as reduced cardiorespiratory fitness is considered an independent risk factor for cardiovascular disease [ 35 ]. Furthermore, intervention duration may have been too short to establish significant changes in cardiorespiratory fitness [ 32 ].…”

Bikram yoga is a style of hatha yoga involving a standarized series of asanas performed to an instructional dialogue in a heated environment (40.6°C, 40% humidity). Several studies evaluating the effect of Bikram yoga on health-related outcomes have been published over the past decade. However, to date, there are no comprehensive reviews of this research and there remains a lack of large-scale, robustly-designed randomised controlled trials (RCT) of Bikram yoga training. The purpose of this review is to contextualise and summarise trials that have evaluated the effects of Bikram yoga on health and to provide recommendations for future research. According to published literature, Bikram yoga has been shown to improve lower body strength, lower and upper body range of motion, and balance in healthy adults. Non-RCTs report that Bikram yoga may, in some populations, improve glucose tolerance, bone mineral density, blood lipid profile, arterial stiffness, mindfulness, and perceived stress. There is vast potential for further, improved research into the effects of Bikram yoga, particularly in unhealthy populations, to better understand intervention-related adaptations and their influence on the progression of chronic disease. Future research should adhere to CONSORT guidelines for better design and reporting to improve research quality in this field.

Studies have demonstrated positive results for people who practice traditional yoga, specifically in body mass index, depression, cancer, sleeping patterns, and diabetes. Most forms of traditional yoga are held in a temperate climate between 293 Kelvin (K) to 295 K; a temperature that is calming and places little stress on the body. Bikram yoga, however, is a more intense form of yoga performed in a hotter climate, typically at 314 K with 40% humidity. The purpose of this study was to determine how Bikram yoga affected blood pressure, body composition, and sleep patterns in beginner and intermediate/experienced practitioners. Participants (N=16) completed 8 weeks of sessions, ranging between 2 to 7 classes per week in a local Bikram yoga program conducted by certified instructors. All participants were assessed prior to the study and again at the end of the eight weeks. A BOD POD (an air displacement plethysmography) was used for body composition assessments, while a digital blood pressure cuff was used to assess blood pressure. In addition, participants were also surveyed on sleep parameters pre and post yoga participation. In combining all subjects, results showed there was a significant improvement (p=0.054) in faster time to fall asleep (27.66 min pre and 23.967 min post), and a trend (p=0.057) towards improved mean arterial pressure (92.20 mmHg pre and 88.33 mm Hg post). There were no differences in weight loss or percent body fat in subjects. This study indicates that there is a trend towards improved blood pressure and significant improvement in sleep parameters after 8 weeks of Bikram yoga for both intermediate/experienced and beginners, but no differences in body composition.
