Bikram yoga training and physical fitness in healthy young adults.
ABSTRACT There has been relatively little longitudinal, controlled investigation of the effects of yoga on general physical fitness, despite the widespread participation in this form of exercise. The purpose of this exploratory study was to examine the effect of short-term Bikram™ yoga training on general physical fitness. Young healthy adults were randomized to yoga training (N=10, 29 ± 6 yrs, 24 sessions in eight weeks) or a control group (N=11, 26 ± 7 yrs). Each yoga training session consisted of 90 min of standardized, supervised postures performed in a heated and humidified studio. Isometric deadlift strength, handgrip strength, lower back/hamstring and shoulder flexibility, resting heart rate and blood pressure, maximal oxygen consumption (treadmill), and lean and fat mass (DEXA) were measured before and after training. Yoga subjects exhibited increased deadlift strength, substantially increased lower back/hamstring flexibility, increased shoulder flexibility, and modestly decreased body fat compared with Control. There were no changes in handgrip strength, cardiovascular measures, or maximal aerobic fitness. In summary, this short-term yoga training protocol produced beneficial changes in musculoskeletal fitness that were specific to the training stimulus.

ABSTRACT: In preparation for a short track speed skating season, eight men and seven women were given yoga sessions during an 8-week high volume training cycle. The sessions were planned according to the postural aspects specific to short track speed skating technical requirements. Three specific goals were selected for the intervention: 1) to observe whether the practice of yoga as postural training could improve the efficiency and the athlete's repertoire along the muscular synergies solicited in the short track speed skating specific technique; 2) to enhance and diversify the motor time-on-task of athletes without changing the prescription of other training stimulus; and 3) to lower the risk of injury during periods with high volumes of training. A total of 36 sessions of yoga were given. Three postural tests were administered before and after the intervention with 14 angles analyzed. Non-parametric Wilcoxon test was used to compare angles' variations. The 36 yoga sessions totalized 986 minutes of motor time-on-task, registering a proportion of 30% of the global motor time-on-task of the training cycle. Improvements were found in eleven of the 14 angles measured when comparing pre- and post-postural tests (P-value from 0.01 to 0.005). During the 8 weeks, excepting traumatic injuries due to short track speed skating accidents, no skaters suffered injuries linked to the high volume of training. Following the intervention, coaches noticed, following their on-ice feedbacks, an adjustment in the efficiency of the skating technique, in particular regarding hip dissociation. These results suggest that yoga could be inserted into out-of-season training cycles, even in a high volume training cycle. Planned with the decision training tools, it allows athletes to diversify their motor time-on-task by integrating a new functional range of generic movements with the solicitation of neuromuscular synergies related to the specificity of their sport.Open Access Journal of Sports Medicine 02/2015; 2015(6):23.

ABSTRACT: To explore the effect of high temperature yoga exercise on improving physical and psychological well-being of overweight middle-aged and young women. 50 overweight middle-aged and young women from yoga clubs were selected. The indexes of their constitution, physiological functions, psychological adaptation were measured and compared before and after one year of uninterrupted high temperature yoga exercise. The indexes of the subjects' constitution and physiological functions were remarkably uplifted (P < 0.05); their psychological adaptation was improved as well. Aerobics represented by high temperature yoga can improve body shape, lower lipid, reduce weight, and exert an evident therapeutic effect on improving physiological functions and boosting psychological well-being.International Journal of Clinical and Experimental Medicine 01/2014; 7(12):5842-6. · 1.42 Impact Factor
