There are eight physiological adaptations that a touch football player would experience in response to training; these include a change in stroke volume, heart rate, cardiac output, oxygen uptake, lung capacity, hemoglobin levels, muscle hypertrophy and the effect on slow- and fast-twitch muscle fibers.
A touch football player would expect to experience the benefits of training after ten weeks. The first of these many benefits includes a change in stroke volume. An athlete’s stroke volume is the amount of blood that is pumped around their body in one beat. In response to training a touch football player’s stroke volume will increase both at rest and during exercise.
This increase is a result of the increase in the size of the heart,

This decreased heart rate is just one of the physiological adaptations that a touch football player would experience as a result of training.
The third physiological adaptation that a touch football player would experience as a result of training is a change in their cardiac output. An athlete’s cardiac output is the volume of blood that their heart ejects per minute, and is therefore a direct result of the stoke volume and heart rate.
When untrained the touch football player’s cardiac output may be around 20 litres per minute, as a result of training this reading would increase to around 25 litres per minute. The formula for cardiac output is ‘stroke volume x heart rate’. As previously discussed, the heart rate heart rate of a touch football player would decrease as a result of training, whereas the stroke volume would increase.
The increase in cardiac output is therefore a result of an increase in stroke volume huge enough to slightly outweigh the decreased heart rate in the equation. As a result of training a touch football player would experience a higher cardiac output, meaning that the body’s cells are replenished more regularly, thus improving the performance of the touch football player.
The fourth, and most significant, response to training that a touch football player would experience is a change in their oxygen uptake. Maximal oxygen uptake, or max VO2, is considered by professionals to be the best guide for cardiorespiratory
Cardiac output adapts throughout a training program. The "American Council on Exercise's Personal Trainer Manual" lists exercise adaptations as increased ventricle size, decreased exercise heart rate and increased stroke volume. Therefore, your heart can maintain a high cardiac output with less effort. Most improvement to cardiac output is contributed to increased stroke volume. Positive adaptations occur in as little as three months of aerobic training.
Speed is a necessity in touch because getting past the opposing defensive line is key. Also, quick reactions with passing rucking etc will help the team’s performance. Cardiorespiratory endurance is a measurement of how well your heart, lungs, and muscles work together to keep your body active over an extended period of time. For a touch football player to be successful in the middle position several components of fitness are needed for the player to be effective. One of the important fitness components for touch football is coordination.
Physical and mental strength plays a major role in a football player’s life. Football is a twelve month process, which consists of off- season (six months), in -season (five months), and the Transition (one month). During off-season the football player’s main goal is gaining strength, size, and much power, in-season they continue to practice and work on maintaining the gains in strength during the off-season, and the transition is when they rest and recuperate their body from the physical exercise. Football players are constantly bumped and knocked down during practices
The relationship between the principles of training and physiological adaptations has a significant impact on performance. Many factors need to be addressed in a training program to make it a successful one for a particular athlete and thus improve their performance.

As heart rate increases during exercise stroke volume will decrease, cardiac output is usually well maintained and the arterial blood pressure declines. Cardiovascular drift will sometimes be associated with a slight increase in the cardiac output directed to the vasodilated skin to increase blood flow to the skin to facilitate heat loss to the environment. According to Lori Cooper with Vanguard Endurance “the amount of blood the heart pumps out per minute (cardiac output) depends on the amount of blood that enters the heart (venous return), fills the ventricles (ventricular filling) and is ejected during heart contractions (stroke volume).” During cardiovascular drift the core temperature increase as heart rate increases, causing stroke volume to decrease to keep cardiac output and oxygen uptake remain the same. In a healthy adult their resting heart rate should be between 60 and 80 beats per minute. The heart rate of a
trained athletes will have a lower heart rate during this period of exercise. Recovery heart rates –
Stroke volume is how much blood is discharged from your heart after each contraction. In an average person, stroke volume averages 50-70ml/beat and can increase up to as high as 110-130ml/beat during intense exercise. In an elite, trained athlete, such as a basketball player, stroke volume averages 90-110ml/beat and is able to increase to as much as 150-220ml/beat. It has been proven that after intense exercise, stroke volume is significantly higher. This allows the heart to pump more blood per minute, which increases the cardiac output during maximal levels of physical activity. The size and number of blood vessels increases due to this.
Touch football is a type of football in which the ball carrier is downed by touching instead of tackling. In the game of touch football, there are many different fitness components that relate to specific touch positions. This essay will evaluate the components of fitness and analysis their relevance to touch football. To complete this, a series of fitness tests were done to help determine my suitability to touch football resulting in a recommendation outlining my suitability to a specific touch football position, based on my fitness.
Several fitness tests were completed such as power, aerobic capacity, muscular endurance, agility etc., in order for us to identify our strengths and weaknesses and which certain components of fitness would be vital in a game of touch football. Fitness tests are essential in all areas of sports for many reasons, such as providing training incentive, identify strengths and weaknesses and gives feedback for the effectiveness of training. In relation to touch, a player needs agility, co-ordination, anaerobic capacity ATP PC, and aerobic capacity. Before all the fitness tests were completed, a beep test was done in order to our fitness level. My beep test just placed me into the average range therefore would be considered a weakness. Aerobic capacity is the most vital component of fitness, and is the ability to keep
By football being a full contact sport, and players always tacking each other it makes it hard on the body (Henderson 1). Bones lose density and strength. (Hobson 1) Ligaments and tendons tend to stiffen, lose circulation, and become more vulnerable. (3) Cartilage becomes stressed and susceptible to tearing.(4).It is every player’s dream is trying to make it to the next level and being the best at what they do. As players work hard to sharpen their game, their body is put through a series of injuries including tears, breaks, and sprains.
The increase in the field of strength and conditioning knowledge has transitioned American Football into a game in which success is dependent on speed and explosiveness. “Running speed over short distances would appear fundamental to success in a number of field and court sports” (2). Coaches spend large quantities of time assessing players and their athletic qualities that underlie playing ability. Strength qualities athletes are highly variable, and are the determinant of their acceleration capabilities. Acceleration demands high force production in a short time period. There is a strong relationship between strength and running speed, resulting in a high level of interest to identify performance factors for different strength
As with the previous two phases the athlete will undergo another series of assessments. This time however the assessments will be different. Whereas before we were looking at areas of explosive strength in sprinting and weighted exercises, this time the emphasis will be placed on cardiovascular endurance. The assessment we will be primarily focused on will be a 1.5 mile run for time and heart rate. The reason we are focused on heart rate is to find his optimal heart rate for prolonged distance. Using a heart monitor we will have him preform the test three time and average of the three heart rates will be the target number. He will of course be allowed a 10 beats per minute cushion to allow for factors that are beyond our control like atmospheric issues such as heat and humidity, and any delayed onset muscle soreness(fitnessschoolbook). Again once all the data has been analyzed we will begin the last phase of the training regime.
Being knowledgeable about the heart is very important, especially if one is an athlete. This experiment is significant, because it can tell us how important it is for one to keep their heart healthy. It will also tell us how playing a sport can benefit one’s health and the well being of their heart. Our hypothesis says, if the athleticism of a person increases, then the heart rate recovery time will decrease when heart rate recovery in a function of athleticism. The purpose of this project is to see which type of athlete, or non-athlete has the best heart function.
Blood comes from the heart. In order to reach the high demand for blood with oxygen, the heart pumps faster and faster in order to let enough blood come out into the body. So the basketball player’s heart rate increases. This is because the working muscle needs more oxygen to contract. The more oxygenated blood the body can supply to working muscles, the greater intensity the basketball player can play the game However, the heart rate cannot keep at a fast rate for all the time.
