Introduction: In this experiment, cardiovascular fitness is being determined by measuring how long it takes for the test subjects' to return to their resting heart rate. Cardiovascular fitness is the ability to "transport and use oxygen while exercising" (Dale 2015). Cardiovascular fitness utilizes the "heart, lungs, muscles, and blood working together" while exercising (Dale 2015). It is also how well your body can last during moderate to high intensity cardio for long periods of time (Waehner 2016). The hypothesis is that people who exercise for three or more days will return to their resting heart rate much faster than people who only exercise for less than three days.

Four interval times (PR, RT, TP and RR) measured in seconds were recorded both with the subject at rest and after the subject had exercised. The PR and RT intervals remained virtually unchanged with the PR intervals remaining the same both before and after exercise with an interval time of 0.15 seconds, and the RT interval increase by 0.01 seconds from 0.37 at rest to 0.38 seconds after exercise. More substantial changes were noted in TP and RR intervals. The TP interval decreasing from 0.32 seconds at rest to just 0.08 seconds after exercise, a decrease of 0.24 seconds (just 25% of the resting 0.32 seconds). The RR interval decreased from 0.84 seconds at rest to 0.61 seconds seconds after exercise, a decrease of 0.23 seconds

Marathon runners put their body through great physical challenges, but in order to prevent physiologic harm, the normal fluid and electrolyte status of an adult marathon runner is important to know. For a normal adult male, the total body water (TBW) in relation to body weight is about 60%, and in females, the percentage is 50 (McCance, 2010). About two thirds of the TBW resides in the intracellular fluid (ICF), in other words blood, and the rest of the TBW remains in the extracellular fluid (ECF), interstitial and intravascular (McCance, 2010). Depending on the age, sex, percent of body fat and exercise status, the TBW will vary among individuals, which is very important in considering the manifestations of fluid replacement in marathon running (Duvillard et al, 2004).

The results of my pulse rate, breathing rate and temperature before and after the exercise are down below.

In the study conducted by Edward H Robinson and Jeffrey R Stout, the use of one weekly interval session at vVO₂max led to a 3% improvement in vVO₂max and a 6% improvement in running(4).The interval duration was set to be 50% of the individual time that the athletes could sustain vVO₂max (the time that VO₂max can be sustained is called tlimvVO₂max or Tmax) which averaged around 3 minutes. The optimum length of VO₂max intervals is not clear although positive results have been found with a range of different interval lengths from 30 seconds up to 3-4

The participants ran for five minutes at there own pace to warm up. To randomize the order the participants were randomly assigned which condition to complete first, barefoot vs. shod. During the experiment the participants ran for two minutes at 3.05 m*s^-1, rested for two minutes, then ran for two minutes at Then had a two-minute rest period and completed the same procedure for the other condition. Each participants stride length was assessed using the distance measured between the first and second initial contact of the left foot.

“Asthma is an example of an obstructive lung disease in which the airways obstruct the outflow of air. In contrast, pulmonary fibrosis is an example of a restrictive lung disease in which the functional size of the lung decreases” (Michael G. Miller, John M. Weiler). Exercise-induced asthma is when the airways are narrowed in the lungs when doing the high-energy activity. In the Journal of Athlete Training, it states that at least fifteen to twenty percent of athletes show evidence of having exercise-induced asthma. Athletes that are affected by exercise-induced asthma may not able to withstand high-intensity training. If not properly treated the athlete would experience symptoms that could worsen. Exercise-induced asthma in athletes requires

Ruth (30’s) and James (50’s) plan on running the Great North Run, their different training regiments giving different physiological states during the run. I will explore how each runner’s training will affect these physiological states and what implications these states will have on the runner.

including running on a treadmill to exhaustion were performed on fifteen participants to record their maximal heart rate and oxygen consumption. Participants ages ranged from 8 to 28 years, and body fat percentages from 14.9% to 33%. After the first tests were completed and the participants allowed their rates to reach normal levels then endured simulated 30 minute motocross races to measure biochemical and functional alterations caused by the racing heat. The results of that test displayed that every one of the participants spent at least 87% of the

The results of this test show that it provides a valid test to estimate aerobic capacity and shows there is a small measurement of error. A polar heart rate monitor was used to measure the heart rate with a step of 30cm in height with a metronome with a beat at 15 steps, per minute and increased by 5 steps every minute for 5 stages or until 80% of the maximum estimated heart rate was reached. The results demonstrated that the Chester Step technique is a valid predictor of aerobic capacity in males and females from a wide range of ages and fitness levels.

All participants in the study were both the experimental and control groups. The sessions were separated by four weeks; the sessions were randomly assigned to the participants. The testing sessions included an orientation with 1RM squat and practice of each test, followed by four conditions four weeks apart. The participants warmed up on the cycle ergometer then completed the DOMS protocol. Data was analyzed using magnitude-based inferences. Baker et.al

I predict that during exercise the heart and respiratory rate (RR) will increase depending on the intensity of exercise and the resting rates will be restored soon after exercise has stopped. I believe that the changes are caused by the increased need for oxygen and energy in muscles as they have to contract faster during exercise. When the exercise is finished the heart and ventilation rates will gradually decrease back to the resting rates as the muscles’ need for oxygen and energy will be smaller than during exercise.
