AIM: pH is the direct indicator of the body reaction following the activities performed. Establishing precise correlations between pH and blood biochemical parameters might support the balancing of values during periods of marked physical activity. METHOD: We conducted a case study in a group of elite rowers. Twelve athletes were included in the study. Monitoring was carried out by collecting biological samples several times a day: in the morning, 80 minutes pre-workout, 12 hours after the last physical effort performed, at two different times, 10 days apart...

Six years ago, I was diagnosed with stage IIIA ovarian low malignant cell potential cancer. It was the most shocking situation I have ever experienced. I didn't realize I had any symptoms, except occasional back pain, which I attributed to starting a new workout program. I had scheduled an abdominal computerized tomography (CT) scan for recurrent microscopic hematuria, which my internist wanted to check. I was told I would hear the results in two days. Two hours after my CT scan, while I was eating ice cream and watching television, an on-call genitourinary doctor (who I did not personally know) called to tell me the good news-that I had kidney stones, thus the microscopic hematuria...

The complexity of the endocrine pathways during recovery related to anabolic function belie an over simplistic approach to its study. This review is to examines the role of resistance exercise (RE) on the recovery responses of three major anabolic hormones testosterone, growth hormone(s) and insulin-like growth factor-I. Each hormone has a complexity related to differential pathways of action as well as interactions with binding proteins and receptor interactions. Testosterone is the primary anabolic hormone and its concentration changes during the recovery period depending upon the up- or down-regulation of the androgen receptor...

BACKGROUND: Few studies have investigated the metabolic demands of functional exercise. We determined the oxygen cost, heart rate (HR) response, and energy expenditure (EE) both during and immediately following a loaded movement training (LMT) workout. METHODS: Ten participants (5 male, age = 23.5 ± 3.7 years, VO2peak = 53.3 ± 6.4 ml∙kg-1∙min- 1) completed baseline resting metabolic rate testing, a maximal oxygen uptake (VO2) test, and a familiarization trial...

Obscure gastrointestinal bleeding is defined as bleeding of unknown origin that persists or recurs (i.e. recurrent or persistent iron deficiency anemia, fecal occult blood test positivity or visible bleeding) after a negative initial workout that necessarily includes gastroscopy and colonoscopy. In clinical practice, small bowel capsule endoscopy is recommended as a third stage examination in these patients, since it is a simple, safe, non-invasive and reliable test. To date there are three available small bowel capsule systems that have gained FDA approval and their diagnostic yield has shown to be superior to other diagnostic modalities for the investigation of the small bowel in patients with obscure gastrointestinal bleeding...

PURPOSE: Athletes and military service members are known to undergo strenuous exercise and sometimes have to take long haul flights soon afterwards; however, its combined effect on many physiological functions is relatively unknown. Therefore, we examined the combined effects of a full-body muscle-damaging workout and transcontinental flight on coagulation and fibrinolysis in healthy, resistance trained men. We also determined the efficacy of a full-body compression garment in limiting their coagulation responses...

Since the pioneering studies conducted in the 1960s in which glycogen status was investigated utilizing the muscle biopsy technique, sports scientists have developed a sophisticated appreciation of the role of glycogen in cellular adaptation and exercise performance, as well as sites of storage of this important metabolic fuel. While sports nutrition guidelines have evolved during the past decade to incorporate sport-specific and periodized manipulation of carbohydrate (CHO) availability, athletes attempt to maximise muscle glycogen synthesis between important workouts or competitive events so that fuel stores closely match to the demands of the prescribed exercise...

Prior research has investigated the effects of either eccentric-only training or comparing eccentric and concentric exercise on changes related to strength and power expression, but no research to date has investigated the impact of altering the duration of either the concentric or eccentric component on these parameters. Therefore, the purpose of this study was to assess the duration of eccentric (i.e. 2-second, 4-second vs. 6-second) muscle contractions and their effect on muscle strength, power production, vertical jump and soreness using a plate-loaded barbell Smith squat exercise...

While music has been found to motivate exercisers during workouts, its potential as a pre-exercise motivator has rarely been investigated. This study evaluated a self-selected, pre-exercise music intervention against implementation intentions (writing down 'if … then …' sentences relating to overcoming barriers) and a control condition. A total of 50 participants (Mage = 43) took part in a longitudinal, randomised, between-participants study, from 99 recruited. For both interventions, participants had significantly more success meeting self-set exercise goals than the control group, and the music group exercised significantly more frequently than the control group...

BACKGROUND: Limited research exists on the effect of a sports dietitian (SD) on athletes' dietary habits and nutrient periodization, which is the deliberate manipulation of macronutrient intake to match training goals. Further, the difference in dietary habits between men and women collegiate athletes has been understudied. A survey questionnaire examining dietary habits and practices was administered to athletes at two universities that employed a full time SD. Not all athletes used the SD as their primary source for nutritional guidance...

BACKGROUND: In 2011, the UK physical activity guidelines were updated to include recommendations for muscle strengthening and balance & coordination (at least two sessions of relevant activities per week). However, monitoring and policy efforts remain focussed on aerobic activity. This study aimed to assess differences by gender and age in the a) prevalence of muscle strengthening and balance & co-ordination guidelines, and b) participation in guideline-specific activities. METHODS: The sample for the muscle strengthening analyses was 10,488 adult (16-64 years) and 3857 older adult (≥65 years) 2012-2014 Scottish Health Survey respondents...

CrossFit is a metabolically demanding strength and conditioning method which performance may benefit from a carbohydrate (CHO)-rich diet. This study investigated the effect of three consecutive days of high CHO intake on CrossFit performance and corresponding metabolically -related variables in strength trained individuals. Eighteen subjects with a CHO intake of <6 g/kg/day were randomly assigned into a CHO (n = 9) or control (C) group (n =9) and underwent a 9-day training protocol. During days 1, 5, and 9, performance was measured as repetitions completed during a 12 minute CrossFit workout...

We report a case of a 39-year-old healthy male presenting with an eruption consisting of evenly spaced, well-circumscribed, round, petechial macules over a discrete region on his back. A detailed history revealed that the man participated in a high-intensity combination workout routine and post-exercise massage. He reported using a regulation-sized dimpled softball in order to massage the musculature of his back. A diagnosis of traumatic petechiae was established. A growing fitness culture encouraging high-intensity training and post-exercise massage coupled with the high costs of professional masseuse services has led to the increased use of self-massage techniques using both traditional and non-traditional massage equipment...

CrossFit is a fitness program that has become increasingly popular in the Western world, but as in other sports, the risk of injury is present. Only a few studies have addressed health benefits and injuries in CrossFit. It is known that chronically overloaded tendons will thicken and increase the risk of tendinopathy. However, it remains unknown whether acute overload caused by strenuous, high-intensity exercise will exert changes in tendons and if these changes can be detected and described by ultrasonography...

BACKGROUND: Previous studies have shown that total-body resistance training (RT) performed two to three alternating days per week has positive effects on muscle strength and body composition. However, no evidence exists to determine if total-body RT workouts done on consecutive days (CD) are beneficial. Therefore, the purpose of this study was to compare the effects of a total-body RT program performed on three con- secutive or nonconsecutive days (NCD) per week for 7 weeks on maximum strength and body composition in recreationally trained subjects...
