Del Coso, J, Salinero, JJ, Lara, B, Gallo-Salazar, C, Areces, F, Herrero, D, and Puente, C. Polygenic profile and exercise-induced muscle damage by a competitive half-ironman. J Strength Cond Res XX(X): 000-000, 2017-To date, it is still unknown why some individuals develop higher levels of muscle damage than other individuals, despite participating in exercise with comparable levels of physical intensity. The aim of this investigation was to analyze 7 single-nucleotide polymorphisms (SNPs) that are candidates to explain individual variations in the level of muscle damage attained during a half-ironman competition...

The Ironman triathlon began in Hawaii in 1978 with 50 participants. Since then, the race has continued to grow in popularity. Injuries are very common among triathletes. Studies have looked at the relationship between injuries and many different factors. Sex, age, and morphological characteristics, such as height, weight, and body mass index, have not been shown to correlate with injury. The association between training volume and injury has shown inconsistent results. This could be due to multiple factors in study design including definitions and evaluation of training volume...

Caffeine's ability to influence upper-body exercise (UBE) endurance performance may be related to an individual's training status. This case study therefore aimed to investigate the ergogenic effects of caffeine dose on 20 km time trial (TT) performance of an elite male Para-triathlete (wheelchair user) (age 46 y, body mass 76.9 kg, body fat 25.4%, handcycling V̇O2peak 3.45 l·min(-1)). The athlete completed four 20 km handcycling TT's on a Cyclus II ergometer under laboratory controlled conditions following the ingestion of 2, 4 and 6 mg·kg(-1) caffeine (CAF) or placebo (PLA)...

BACKGROUND: An extensive body of literature exists on the effects of training on haematological parameters, but the previous studies have not reported how hematological parameters respond to changes in training loads within consecutive phases of the training cycle in highly-trained athletes in extremely different sport disciplines. The aim of this study was to identify changes in red blood cell (RBC) profile in response to training loads in consecutive phases of the annual training cycle in highly-trained sprinters (8 men, aged 24 ± 3 years) and triathletes (6 men, aged 24 ± 4 years) who competed at the national and international level...

OBJECTIVE: High-quality training is a key determinant of performance in the Olympic distance triathlon and is potentially influenced by a unique array of context-specific biopsychosocial factors. Our objective was to explore and describe these factors among squad members of a university-based, elite Olympic distance triathlete developmental programme. METHOD: A qualitative investigation using a visual communication tool-assisted focus group and longitudinal semistructured individual interviews was conducted...

The aim of this study was to evaluate the effects of taurine and chocolate milk supplementation on oxidative stress and protein metabolism markers, and aerobic parameters in triathletes. Methods: A double-blind, crossover study was conducted with 10 male triathletes, aged 30.9 ± 1.3 year, height 1.79 ± 0.01 m and body weight 77.45 ± 2.4 kg. Three grams of taurine and 400 ml of chocolate milk (TAUchoc), or a placebo (chocolate milk) (CHOC) was ingested post exercise for 8 weeks. Oxidative stress marker levels, and 24 h urinary nitrogen, creatinine, and urea excretion were measured before and after 8 weeks of training and supplementation with TAUchoc or CHOC...

Oxygen uptake ([Formula: see text]) kinetics has been reported to be influenced by the activity mode. However, only few studies have compared [Formula: see text]O2 kinetics between activities in the same subjects in which they were equally trained. Therefore, this study compared the [Formula: see text]O2 kinetics response to swimming, arm cranking, and cycling within the same group of subjects within the heavy exercise intensity domain. Ten trained male triathletes (age 23.2 ± 4.5 years; height 180.8 ± 8...

Periostal avulsion of m. vastus medialis is a very rare injury. To our knowledge, it has not previously been described, and there is no treatment algorithm. A 32-year-old male professional triathlete experienced this type of injury during a final sprint in a competition. He achieved a good functional result after treatment with an optimal rehabilitation regimen, and approximately four months after the injury he won a medal in a major international event.

OBJECTIVE: The present study compares the effect of ingesting hydrolyzed beef protein, whey protein, and carbohydrate on performance, body composition (via plethysmography), muscular thickness, and blood indices of health, including ferritin concentrations, following a 10-week intervention program. METHODS: After being randomly assigned to one of the following groups-beef, whey, or carbohydrate-24 master-age (35-60 years old) male triathletes (n = 8 per treatment) ingested 20 g of supplement mixed with plain water once a day (immediately after training or before breakfast)...

PURPOSE: We sought to determine the effect of high- vs. low-intensity training in the heat and ensuing taper period in the heat on endurance performance. METHODS: Nineteen well-trained triathletes undertook 5 days of normal training and a 1-week taper, including either low- (HA-L, n=10) or high-intensity (HA-H, n=9) training sessions in the heat (30°C, 50% of relative humidity). A control group (n=10) reproduced their usual training in thermoneutral conditions...

Life-history theory is a cornerstone of modern evolutionary biology that addresses myriad phenomena ranging from demography and population structure to the evolution of aging and senescence. Trade-offs may arise in a number of contexts, from allocation-based (e.g., egg size vs. egg number) to genomic conflicts (e.g., intralocus sexual conflict in which genes that perform well in males perform poorly in females). Here we test for performance tradeoffs in human athletes. We show that in Ironman triathletes, swimming performance trades off with cycling and running performance...

PURPOSE: The present study was performed to determine the impact of hypoxia on working muscle oxygenation during incremental running, and to compare tissue oxygenation between the thigh and calf muscles. METHODS: Nine distance runners and triathletes performed incremental running tests to exhaustion under normoxic and hypoxic conditions (fraction of inspired oxygen = 0.15). Peak pulmonary oxygen uptake ([Formula: see text]) and tissue oxygen saturation (StO2) were measured simultaneously in both the vastus lateralis and medial gastrocnemius...

BACKGROUND: The practice of prolonged exercise with high intensity, as seen in triathlon training, can cause physiological imbalances that might result in muscle fatigue, muscle damage and changes in systemic inflammatory response, thus reduce the athletes physical performance, therefore, both adequate total caloric and macronutrient intake also the use of a specific ergogenic aid, as taurine supplementation would be an alternative to prevent inflammation and muscle damage. In order to verify the effects of 8 weeks of taurine and chocolate milk supplementation, markers of muscle damage, inflammation, and aerobic capacity were quantified in triathletes...

Triathletes need to effectively fuel during training and racing to maximize their potential for success. While most research on fueling has focused on elite male triathletes, triathlon participation encompasses a broader demographic of racers ranging from those with aspirations of winning to those whose goals are completion. Carbohydrate is the primary macronutrient for fueling endurance activities. Athletes can usually tolerate 60 to 90 mg·h in the form of multiple different carbohydrate sources. Athletes should drink as thirst dictates and consider sodium replacement of sweat loss especially in individuals with a history of exercise-associated muscle cramps...
