Abstract

Schoenfeld, BJ, Grgic, J, Ogborn, D, and Krieger, JW. Strength and hypertrophy adaptations between low- vs. high-load resistance training: a systematic review and meta-analysis. J Strength Cond Res 31(12): 3508-3523, 2017-The purpose of this article was to conduct a systematic review of the current body of literature and a meta-analysis to compare changes in strength and hypertrophy between low- vs. high-load resistance training protocols.

Searches of PubMed/MEDLINE, Cochrane Library, and Scopus were conducted for studies that met the following criteria: (a) an experimental trial involving both low-load training [≤60% 1 repetition maximum (1RM)] and high-load training (>60% 1RM); (b) with all sets in the training protocols being performed to momentary muscular failure; (c) at least one method of estimating changes in muscle mass or dynamic, isometric, or isokinetic strength was used; (d) the training protocol lasted for a minimum of 6 weeks; (e) the study involved participants with no known medical conditions or injuries impairing training capacity. A total of 21 studies were ultimately included for analysis. Gains in 1RM strength were significantly greater in favor of high- vs. low-load training, whereas no significant differences were found for isometric strength between conditions. Changes in measures of muscle hypertrophy were similar between conditions.

The findings indicate that maximal strength benefits are obtained from the use of heavy loads while muscle hypertrophy can be equally achieved across a spectrum of loading ranges.

Yoga and physical exercise - a review and comparison

Ramajayam Govindaraj 1, Sneha Karmani 1, Shivarama Varambally 1, B N Gangadhar 1

PMID: 27044898 DOI: 10.3109/09540261.2016.1160878

Abstract

Yoga is a multifaceted spiritual tool with enhanced health and well-being as one of its positive effects. The components of yoga which are very commonly applied for health benefits are asanas (physical postures), pranayama (regulated breathing) and meditation. In the context of asanas, yoga resembles more of a physical exercise, which may lead to the perception that yoga is another kind of physical exercise. This article aims at exploring the commonalities and differences between yoga and physical exercise in terms of concepts, possible mechanisms and effectiveness for health benefits. A narrative review is undertaken based on traditional and contemporary literature for yoga, along with scientific articles available on yoga and exercise including head-to-head comparative trials with healthy volunteers and patients with various disease conditions. Physical exercises and the physical components of yoga practices have several similarities, but also important differences. Evidence suggests that yoga interventions appear to be equal and/or superior to exercise in most outcome measures. Emphasis on breath regulation, mindfulness during practice, and importance given to maintenance of postures are some of the elements which differentiate yoga practices from physical exercises.

Effects of yogic intervention on pain scores and quality of life in females with chronic pelvic pain

Rahul Saxena, Manish Gupta, Nilima Shankar, Sandhya Jain,1 and Arushi Saxena1

Abstract

Context:

Chronic pelvic pain (CPP) is a common condition of women of the reproductive age group. It has a negative impact on a woman's personal health and quality of life (QOL). Practicing yoga has shown numerous benefits in various chronic painful conditions.

Aim:

To study the effects of yogic intervention on pain scores and quality of life in females of reproductive age group with CPP, on conventional therapy.

Settings and Design:

It is a follow-up, randomized case-control study done in a tertiary care hospital.

Subjects and Methods:

Sixty female patients of CPP in the age group of 18–45 years were randomly divided into Group I (n = 30) and Group II (n = 30). Group I received only conventional therapy in the form of NSAIDS and Group II received yoga therapy in the form of asanas, pranayama, and relaxation along with the conventional therapy for 8 weeks. They were assessed twice (pre- and post-treatment) for pain scores through visual analog scale (VAS) score and QOL by the World Health Organization quality of life-BREF (WHOQOL-BREF) questionnaire.

Statistical Analysis Used:

Repeated measure ANOVA followed by Tukey's test. P < 0.05 was considered significant.

Results:

After 8 weeks of yogic intervention, Group II patients showed a significant decrease in intensity of pain seen by a decrease in VAS score (P < 0.001) and improvement in the quality of life with a significant increase (P < 0.001) in physical, psychological, social, and environmental domain scores of WHOQOL-BREF.

Conclusions:

The practice of yoga causes a reduction in the pain intensity and improves the quality of life in patients with chronic pelvic pain.

Key words: Chronic pelvic pain, pain scores, quality of life, World Health Organization quality of life-BREF, yoga

INTRODUCTION

Chronic pelvic pain (CPP) is defined as an “intermittent or constant pain in the lower abdomen or pelvis of a woman, of at least 6 months duration, not occurring exclusively with menstruation or intercourse and not associated with pregnancy.[1] It is a common condition of the reproductive age of group women, yet its pathophysiology remains poorly understood.[2] In South-East Asian countries, the prevalence of CPP varies from 5.2% in India, 8.89% in Pakistan to 43.2% in Thailand.[3] CPP has a negative impact on a woman's personal health and quality of life (QOL).[4,5]

Though the exact etiology is unknown but CPP may occur due to the involvement and the complex interactions between of gynecological, gastrointestinal, urinary, musculoskeletal, endocrine, and neurologic systems. It may also be influenced by psychological and sociocultural factors.[6] Common conditions that cause CPP are endometriosis, chronic pelvic inflammatory disease, adenomyosis, fibroids, adhesions, celiac disease, colitis, inflammatory bowel disease, fibromyalgia, degenerative disk disease, and chronic urinary tract infection.[7]

The common presentations of CPP are noncyclic lower abdominal pain seen in about 80% of women, congestive dysmenorrhea in 26%, and pelvic tenderness in 20% of cases.[8] Symptoms of depression, anxiety, low QOL, low productivity, decreased energy, sexual dysfunction, and relationship problems are also present in these patients of CPP.[9,10]

The treatment of CPP entails two aspects, one is the treatment of chronic pain, and the other is the treatment of the underlying cause. In most cases, an effective treatment can be achieved by using both approaches. The treatment can be medical or surgical but for those women in whom a definitive diagnosis cannot be reached (61% of women with CPP reported that the etiology was unknown), it requires a multidisciplinary approach, i.e., addressing dietary, social, environmental, and psychological factors in addition to standard medical therapy.[10,11]

Yoga is an effective, time-tested method for improving overall health and managing psychosomatic and chronic degenerative disorders.[12] Practicing yoga regularly has shown improvement in QOL and pain reduction in chronic low back pain.[13,14] Prevalence of musculoskeletal pain (neck pain and lower back pain) was found to be lower in dentists with regular yoga practice as compared to dentists practicing other physical activities or with no physical activity.[15] Yoga therapy has shown a reduction in severity and duration of pain in women with primary dysmenorrhea.[16] Literature survey however has shown a paucity of studies on the beneficial effects of yoga on pain and QOL in females with CPP.

We hypothesized that the use of yogic intervention used along with conventional therapy in CPP patients will help in improving visual analog scale (VAS) score and QOL as compared to conventional therapy alone. The primary objective of our study was to measure VAS score and World Health Organization QOL-BREF (WHOQOL-BREF) scores in CPP patients on conventional therapy and in CPP patients on both conventional + yoga therapy.........

PMID: 23930026 PMCID: PMC3734644 DOI: 10.4103/0973-6131.113391

Abstract

Now-a-days reproductive health problems along with infertility in male is very often observed. Various Assisted Reproductive Technologies have been introduced to solve the problem, but common people cannot afford the cost of such procedures. Various ayurvedic and other alternative medicines, along with regular yoga practice are proven to be not only effective to enhance the reproductive health in men to produce a successful pregnancy, but also to regulate sexual desire in men who practice celibacy. Yoga is reported to reduce stress and anxiety, improve autonomic functions by triggering neurohormonal mechanisms by the suppression of sympathetic activity, and even, today, several reports suggested regular yoga practice from childhood is beneficial for reproductive health. In this regard the present review is aimed to provide all the necessary information regarding the effectiveness of yoga practice to have a better reproductive health and to prevent infertility.
