Relatively few studies have investigated peripheral sweating mechanisms of long-distance runners. The aim of this study was to compare peripheral sweating mechanisms in male long-distance runners, and sedentary counterparts. Thirty six subjects, including 20 sedentary controls and 16 long-distance runners (with 7-12 years of athletic training, average 9.2±2.1 years) were observed. Quantitative ...

PURPOSE This study examined the validity of a squash-specific test designed to assess endurance capability and aerobic power. METHODS Eight squash players and eight runners performed, in a counterbalanced order, incremental treadmill (TT) and squash-specific (ST) tests to volitional exhaustion. Breath-by-breath oxygen uptake was determined by a portable analyzer and heart rate was assessed te...

purpose the aim of this study was to compare the levels of serum immunoglobulin (iga, igm, igg), testosterone and cortisol in semi-endurance elite runners during general preparation and competition phase of training. methods thirteen semi-endurance elite male runners with an average age of 18.92±1.7 years volunteered to take part in this study. the runners participated in the selected training ...

BACKGROUND Despite the increasing popularity of marathons, little research has examined the training habits of nonelite marathon runners. Given that nonelite runners, particularly those with a competitive motive, have a higher risk for injury than experienced elite runners, it is important for physicians to understand the training program and features that might distinguish running performance ...

Background. Running is increasingly popular in Indonesia as a recreational and competitive sport. Training volume per week known to be associated with the cardiorespiratory fitness of runners. A straightforward method assessing by measuring resting heart rate (RHR).
 Objective. This study aimed analyze RHR its runners, non-runners city Padang, West Sumatera.
 Methods. cross-sectional ...

Moderate-intensity treadmill running can alter male Apc(Min/+) mouse polyp formation. This purpose of this study was to examine whether exercise mode differentially affects Apc(Min/+) mouse intestinal polyp development in male and female mice. Male and female Apc(Min/+) mice were randomly assigned to control, treadmill (18 m/min; 60 min/day; 6 days/wk), or voluntary wheel running (24-h access) ...

Trabecular bone of the human calcaneus is subjected to extreme repetitive forces during endurance running and should adapt in response to this strain. To assess possible bone functional adaptation in the posterior region of the calcaneus, we recruited forefoot-striking runners (n = 6), rearfoot-striking runners (n = 6), and non-runners (n = 6), all males aged 20-41 for this institutionally appr...

OBJECTIVES To investigate the effects of voluntary running on the incidence and severity of osteoarthritis (OA) and associated changes in cartilage matrix and subchondral bone in a transgenic Del1 mouse model for OA. METHODS Del1 mice and their non-transgenic littermate controls were housed from the age of 5-6 weeks to 15 months in individual cages with running wheels. The running activity of...

CONTEXT Gastrointestinal (GI) distress is common during ultrarunning. PURPOSE To determine if race diet is related to GI distress in a 161-km ultramarathon. METHODS Fifteen (10 male, 5 female) consenting runners in the Javelina Jundred (6.5 loops on a desert trail) participated. Body mass was measured immediately prerace and after each loop. Runners reported if they had nausea, vomiting, ab...

Critical physiological factors for performance in running are maximal oxygen consumption (VO(2max)), fractional VO(2max) utilization and running economy. While Kenyan and Caucasian elite runners are able to reach very high, but similar maximal oxygen uptake levels, the VO(2max) of black South African elite runners seems to be slightly lower. Moreover, the studies of black and white South Africa...
