“…In addition, significant differences have been reported for the effects of living and eating habits in patients with chronic constipation, although exercise caused no significant difference in CTT 9,23. Some studies have reported that PAL affected the body constituents and eating habits, and hence CTT 23-25. In the current study, there was a significant difference among the 3 subgroups of the female subjects.…”

Background/AimsPhysical activity (PA) is associated with a reduced risk of colorectal cancer. Thus, we examined the colon transit time (CTT) according to the physical activity level (PAL) in Korean adults.MethodsThe study subjects were 49 adults: 24 males and 25 females. The subjects used an accelerometer for 7 consecutive days to measure the 1-week PAL. The subjects took a capsule containing 20 radio-opaque markers for 3 days. On the fourth day, a supine abdominal radiography was performed. According to the total activity count of all study subjects, the upper 25%, middle 50% and lower 25% were classified into the high (H), moderate (M) and low (L) physical activity (PA) groups, respectively.ResultsThe total CTT was significantly longer in the female (25.8 hours) than in the male subjects (7.4 hours) (P = 0.002). In regard to difference on PAL, although there was no significant difference among the male subjects, the right CTT in the female subjects was significantly shorter in H group than in M group (P = 0.048), and the recto-sigmoid CTT was significantly shorter in H group than in L group (P = 0.023). Furthermore, there were significant differences in total CTT between L and M groups (P = 0.022), M and H groups (P = 0.026) and between L and H groups (P = 0.002).ConclusionsThe female, but not male, subjects showed that moderate and high PAL assisted colon transit.

“…Exercise has also been shown to decrease transit time, particularly through the descending colon (74,75) . Previous reports have suggested however, that physical activity does not necessarily improve overall GI transit (76) . It may be convenient therefore to view the colon as a chemostat, a commonly used form of bioreactor, which has been applied in microbiological settings for the determination of growth parameters (Fig.…”

The multifactorial interplay of diet, the microbiome and appetite control: current knowledge and future challenges

The recent availability of high-throughput nucleic acid sequencing technologies has rapidly advanced approaches to analysing the role of the gut microbiome in governance of human health, including gut health, and also metabolic, cardiovascular and mental health, inter alia. Recent scientific studies suggest that energy intake (EI) perturbations at the population level cannot account for the current obesity epidemic, and significant work is investigating the potential role of the microbiome, and in particular its metabolic products, notably SCFA, predominantly acetate, propionate and butyrate, the last of which is an energy source for the epithelium of the large intestine. The energy yield from dietary residues may be a significant factor influencing energy balance. This review posits that the contribution towards EI is governed by EI diet composition (not just fibre), the composition of the microbiome and by the levels of physical activity. Furthermore, we hypothesise that these factors do not exist in a steady state, but rather are dynamic, with both short-and medium-term effects on appetite regulation. We suggest that the existing modelling strategies for bacterial dynamics, specifically for growth in chemostat culture, are of utility in understanding the dynamic interplay of diet, activity and microbiomic organisation. Such approaches may be informative in optimising the application of dietary and microbial therapy to promote health. OverviewThe availability of high-throughput nucleic acid sequencing technologies has facilitated a range of new approaches to analysing the role of the gut microbiome in governance of human health (1) . Modern techniques suggest a role for the microbiome maintenance of, not only gut health but also systemic conditions, including cardiovascular health (2) , mental health (3) and obesity (3) . Despite wide media focus on excess energy intake (EI), recent scientific studies suggest EI perturbations at the population level cannot account for the current obesity epidemic (4) . The microbiome is responsible for the production of a highly complex and highly dynamic metaexometabolome. Well-known components of this include the SCFA acetate, propionate and butyrate, the last of which is an energy source for the epithelium of the large intestine (5) , as well as an inhibitor of histone deacetylation (and thereby cell fate determination) (6) . The energy yield from dietary residues entering the large intestine may account for as much as 10 % of EI (7) and is therefore a significant factor influencing energy balance. The guiding theme of this review is that this contribution towards EI is governed by EI, diet composition, the composition of the microbiome and levels of physical activity. Furthermore, we hypothesise that these factors do not exist in a steady state, but rather are dynamic, with both short-and medium-term effects

“…Similar to diet, there is no unanimous opinion about the effects of increased physical activity in managing constipation, as there are a few studies in favour of it [28][29][30] and a few against it. 26,[31][32][33] To our knowledge, there has been no study looking at its efficacy in individuals with NBD.…”

Neurogenic bowel dysfunction is a severely troubling entity for patients with neurological disease or injury. The complex symptom cluster presents a challenge, not only for the patients but also for the treating clinician. Without intervention, patients are bound to have a reduced quality of life, and experience social impacts and secondary complications that come along with it. A careful initial assessment provides an idea of symptom severity and is crucial for successful rehabilitation. The mainstay of treatment remains a conservative approach of managing faecal incontinence or optimising the mechanics of defecation to improve patient’s quality of life. This article attempts to provide a comprehensive review of existing literature on pathophysiology, assessment and management of neurogenic bowel dysfunction.
