Since players from the Professional Australian Football League were sometimes required to travel during the winter from their normal residences for training and living in southern Australia where the temperature range is 12-18 degrees Celsius /53.6-64.4 degrees Fahrenheit to northern Australia where the temperature range is 30-35 degrees Celsius/86-95 degrees Fahrenheit, their bodies go through…
Older Athletes in hot environments
Studies have shown that older adults have more of a heat challenge than younger adults with higher core temperatures, greater loss of body fluid, lower sweating rates, and higher heart rates. Some things that could affect heat tolerance independent of age would be a decreases in lean body mass, decrease in aerobic capacity, sedentary lifestyle,…
Cold Habituation on Manual Dexterity
Exposure to a cold environment will result in impaired nerve signaling for both sensory and motor neurons, this means not only are our muscles affected during exercise but so is our dexterity and coordination, which is as essential to sports as muscular endurance. How as athletes can we decrease the diminishing affects of a cold…
The Impact of Temperature on Major League Baseball
Bradley Lanier Journal Article The Effect of Temperature on Baseball My article focused on the effect that temperature has on the sport of baseball. The researchers examined how game statistics like batting average, homeruns, walks, strikeouts, and runs scored are affected by the environment in which a game is played. They collected data from 22,215…
Electrically Stimulated Antagonist Muscle Contraction Increased Muscle Mass and Bone Mineral Density of One Astronaut – Initial Verification on the International Space Station
A well know negative a effect of weightlessness, such as an astronaut staying on the International Space Station (ISS), is Musculoskeletal Atrophy. Without the presence of gravity the body of an astronaut does not experience the daily load that it would on Earth. Henceforth, muscles do not receive an adequate amount of stimuli during space…
Running Mechanical Alterations During Repeated Treadmill Sprints in Hot vs. Hypoxic Environments
Due to so many sports being played in hot environments or at altitude, it is important for us to understand the implications of heat stress and hypoxia on performance. The purpose of this study was to compare performance changes and alterations in running mechanics over a series of treadmill sprints that were performed in severely…
Prevalence of Exercise-Induced Bronchospasm in Long Distance Runners Trained in Cold Weather – Zach Noltemeyer
Exercise-induced Bronchospasm is transient airflow obstruction that results from exercise. Heat and water loss in the airways as a result of hyperventilation are thought to be the main factor in development of Exercise-induced Bronchospasm. This particular study sought to understand the relationship between cold weather and development of the condition. The study was completed in Erzurum, Turkey….
Cardiac Biomarkers at Altitude
In 2014, Mellor and colleagues conducted a study examining cardiac biomarkers at altitude, and their relationship to high pulmonary artery systolic blood pressure (PASP), as well as acute mountain sickness (AMS). Cardiac biomarkers can be used to predict and diagnose several clinical conditions. However, the authors of this study were concerned with the ability of cardiac…
Effects of Seated and Standing Cold Water Immersion on Recovery from Repeated Sprinting
A randomized controlled experiment was conducted to investigate the effects of hydrostatic pressure with cold-water immersion at strenuous levels of exercise on indicators of damage and recovery. Twenty-four males subjects of the ages 23 to 27 with body masses between 81.4 to 90.1 kg, and Vo2maxx between 57.5 to 62.4 ml/kg/min. All 24 subjects were…
High Altitude Effects on Elite Level Soccer Players
The article I reviewed documented the effects of altitude on elite level soccer matches by analyzing the scores and results of 1,460 international soccer matches played at various altitudes in 10 South American countries. The effects of altitude were determined by controlling for the individual team’s ability by using probability of a win, goals scored,…
Examining the Results of Certain Effects of High Altitude on Soldiers Using Modeling and Simulation
The article I chose to summarize was entitled “Examining the Results of Certain Effects of High Altitude on Soldiers Using Modeling and Simulation.” The researchers hoped to find the effects of altitude on soldiers engaged in combat. At the outset of the War on Terror, soldiers fighting in Afghanistan, a country that ranges in elevations…
The Effects of Elapsed Time After Warm-Up on Subsequent Exercise Performance in a Cold Environment
Warm-up is key before any athletic or exercise event, and timing is of the utmost importance to every athlete, coach, trainer, and team who competes in these types of events on a professional level. Benefits of the warm-up include increase of body temperature, enhanced metabolic reactions, faster contraction and relaxation of both agonist and antagonist…
