Hydration and Hot Yoga: Encouragement, Behaviors, and Outcomes.

CONTEXT: Currently, the literature on hot yoga is lacking, and there is still much to understand regarding the safety of these practices. However, one point of safety often emphasized is hydration during the practice of hot yoga. AIM: The aim of this study was to examine hydration encouragement by hot yoga instructors and hydration behaviors and related outcomes by hot yoga participants. METHODS: A cross-sectional study (n = 700) collected self-report data on demographics, types and frequency of yoga practiced, hydration behaviors, and self-report measures of adverse outcomes experienced by participants during hot yoga. Associations between hydration encouragement, protective behaviors, and adverse outcomes were analyzed through Chi-square tests. RESULTS: Every protective hydration behavior was significantly associated with instructor encouragement (P < 0.05). Hydration before or during hot yoga participation was associated with a lower occurrence of dehydration symptoms (P < 0.05). CONCLUSIONS: Hot yoga instructors hold a key role in encouraging hydration and student safety outcomes.

Self-Reported Benefits and Adverse Outcomes of Hot Yoga Participation.

BACKGROUND: There is little to no scientific data about the health benefits or risks to participating in hot yoga, in particular distinguishing it from the practice of non-hot yoga. AIMS: This study aims to provide some preliminary evidence about the risks and benefits of participating in hot yoga. Future studies will be able to build off the findings herein. METHODS: This study utilized online survey software (Qualtrics) and recruited participants through convenience sampling (n = 157) by targeting yoga websites and online forums. As there is currently no known questionnaire that has been developed to assess the risks and benefits of hot yoga participation, an exploratory measure was designed to gain more detailed responses from participants. Descriptive epidemiological analyses we re conducted. RESULTS: Participants of hot yoga had a number of pre-existing health conditions. Both benefits and adverse outcomes were reported. The most frequently reported health benefits of hot yoga in this sample included increased flexibility (63%), improved mood (58%), increased fitness (43%), and improved stamina (42%). Just over half of the participants reported some sort of adverse event during a hot yoga session (n = 82). The most commonly reported adverse events included dizziness (60%), feeling light headed (61%), nausea (35%), and dehydration (34%), amongst others. CONCLUSIONS: Further study on the risks and benefits of hot yoga participation is required.

Impact of 10-weeks of yoga practice on flexibility and balance of college athletes.

BACKGROUND: With clearer evidence of its benefits, coaches, and athletes may better see that yoga has a role in optimizing performance. AIMS: To determine the impact of yoga on male college athletes (N = 26). METHODS: Over a 10-week period, a yoga group (YG) of athletes (n = 14) took part in biweekly yoga sessions; while a nonyoga group (NYG) of athletes (n = 12) took part in no additional yoga activity. Performance measures were obtained immediately before and after this period. Measurements of flexibility and balance, included: Sit-reach (SR), shoulder flexibility (SF), and stork stand (SS); dynamic measurements consisted of joint angles (JA) measured during the performance of three distinct yoga positions (downward dog [DD]; right foot lunge [RFL]; chair [C]). RESULTS: Significant gains were observed in the YG for flexibility (SR, P = 0.01; SF, P = 0.03), and balance (SS, P = 0.05). No significant differences were observed in the NYG for flexibility and balance. Significantly, greater JA were observed in the YG for: RFL (dorsiflexion, l-ankle; P = 0.04), DD (extension, r-knee, P = 0.04; r-hip; P = 0.01; flexion, r-shoulder; P = 0.01) and C (flexion, r-knee; P = 0.01). Significant JA differences were observed in the NYG for: DD (flexion, r-knee, P = 0.01: r-hip, P = 0.05; r-shoulder, P = 0.03) and C (flexion r-knee, P = 0.01; extension, r-shoulder; P = 0.05). A between group comparison revealed the significant differences for: RFL (l-ankle; P = 0.01), DD (r-knee, P = 0.01; r-hip; P = 0.01), and C (r-shoulder, P = 0.02). CONCLUSIONS: Results suggest that a regular yoga practice may increase the flexibility and balance as well as whole body measures of male college athletes and therefore, may enhance athletic performances that require these characteristics.

A randomized controlled bicenter trial of yoga for patients with colorectal cancer.

OBJECTIVE: The aim of this trial was to evaluate the effects of yoga on health-related quality of life in patients with colorectal cancer. METHODS: Patients with non-metastatic colorectal cancer were randomly assigned to a 10-week yoga intervention (90 min once weekly) or a waitlist control group. Primary outcome measure was disease-specific quality of life (Functional Assessment of Cancer Therapy - Colorectal [FACT-C]) at week 10. Secondary outcome measures included FACT-C subscales: spiritual well-being (FACT - Spirituality); fatigue (FACT - Fatigue); sleep disturbances (Pittsburgh Sleep Quality Inventory); depression and anxiety (Hospital Anxiety and Depression Scale); body awareness (Scale of Body Connection); and body-efficacy expectations (Body-Efficacy Expectations Scale). Outcomes were assessed at week 10 and week 22 after randomization. RESULTS: Fifty-four patients (mean age 68.3 ± 9.7 years) were randomized to yoga (n = 27; attrition rate 22.2%) and control group (n = 27; attrition rate 18.5%). Patients in the yoga group attended a mean of 5.3 ± 4.0 yoga classes. No significant group differences for the FACT-C total score were found. Group differences were found for emotional well-being at week 22 (∆ = 1.59; 95% CI = 0.27,2.90; p = 0.019), sleep disturbances at week 22 (∆ = -1.08; 95% CI = -2.13, -0.03; p = 0.043), anxiety at week 10 (∆ = -1.14; 95% CI = -2.20, -0.09; p = 0.043), and depression at week 10 (∆ = -1.34; 95% CI = -2.61, -0.8; p = 0.038). No serious adverse events occurred in the yoga group, while liver metastases were diagnosed in one patient in the control group. CONCLUSION: This randomized trial found no effects of yoga on health-related quality of life in patients with colorectal cancer. Given the high attrition rate and low intervention adherence, no definite conclusions can be drawn from this trial.

Student perceptions and practices regarding carrying concealed handguns on university campuses.

OBJECTIVE: This multisite study assessed college student's perceptions and practices regarding carrying concealed handguns on campus. PARTICIPANTS: Undergraduate students from 15 public midwestern universities were surveyed (N = 1,800). METHODS: Faculty members distributed the questionnaire to students in general education classes or classes broadly representative of undergraduate students. RESULTS: Useable questionnaires were returned by 1,649 students (92%). The majority (78%) of students was not supportive of concealed handguns on campuses, and 78% claimed that they would not obtain a permit to carry a handgun on campus, if it were legal. Those who perceived more disadvantages to carrying handguns on campus were females, who did not own firearms, did not have a firearm in the home growing up, and were not concerned with becoming a victim of crime. CONCLUSIONS: The majority of students was not supportive of concealed handguns on campus and claimed that they would not feel safer if students and faculty carried concealed handguns.

Nursing home staff members' attitudes and knowledge about urinary incontinence: the impact of technology and training.

Urinary incontinence (UI) poses challenges for nursing home personnel. The authors of this study explored differences in attitude and knowledge about UI among registered nurses, licensed practical nurses, and certified nursing assistants working in skilled nursing homes before and after study interventions.
