This group will start the testing by attaining the medical records of the player to see if he is physically and physiologically capable to perform such strenuous activities. After that information is attained we will start by testing the player’s endurance with a two mile run and monitor the times, heart rate, Vo2 max, and try to evaluate the lactic threshold. Thereafter in the following days, we will attain the midfielder’s 1RM in all multiple joint lifts giving us a baseline for our percentages.

Age, height, and sex all have an effect on predicting lung volume. For flow rate, exercise is predicting factor. From the data, we see that males have higher PEFs and FVCs. This is most likely because of more muscles mass, height, and we have many male athletes. This supports the ideas that sex, increased height, and increased mass all increase the lung volumes.

The Wingate Anaerobic Test is used to evaluate anaerobic cycling performance. This study was undertaken to determine whether there is a relationship between peak power and fatigue index for endurance (n=9) vs power (n=4) athletes. A total of 13 subjects, including 8 males and 5 females, were included in the study. The subjects were divided into sporting types, such as endurance and power. Data collected from the Wingate test included peak power (W), mean power (W), time to peak (S), minimum power (W) and fatigue index (%). When the peak power and fatigue index were considered together for endurance athletes, a significant relationship

A persons lung capacity can determine someone’s exercise level because if you have a larger lung capacity it allows your body to take in more oxygen which gives your muscles more energy which means you can do exercise for a longer amount of time.

The prevalence of asthma has steadily grown in both the US and world populations, and continues to do so. In the US alone, 25 million people were diagnosed with asthma by 2010 (CDC, 2013). In turn, the need to accurately assess the functionality of a patient’s lung capacity is an essential step to begin diagnosis and treatment of their condition. This paper examines the mechanical peak flow meter, which was crafted for assessing lung function capacity in asthmatic patients. In addition, comparing the advantages and disadvantages of usage of the peak flow meter, as well as the proper usage. Among the various instruments used to assess a patient’s lung capacity, the mechanical peak flow meter is the most widely used and among one of the most precise measurement tools (CDC, 2013).

Participants in this study performed two types of tasks: chest wall maneuvers and speech breathing activities. The chest wall tasks consisted of many different maneuvers, including isovolume, vital capacity, rib cage capacity, abdominal capacity, and relaxation maneuvers. Isovolume maneuvers were conducted, in which the participant displaced volume back and forth from the abdomen to the rib cage with a closed larynx. In vital capacity maneuvers, the participant inspired maximally from resting expiratory level then expired maximally. The minimum and maximum rib cage volumes during the vital capacity maneuver determined rib cage capacity maneuvers, and abdominal capacity maneuvers consisted of the range of abdominal volumes while the participant held their breath. Lastly, relaxation maneuvers were performed in which the participant completely relaxed the chest wall muscles while keeping their larynx closed. Speech breathing activities consisted of two measures: extemporaneous speech and reading speech. For the extemporaneous speech activity, the participant spoke 10 to 20 breath groups about the topic of his choice. For the reading speech activity, the participant read a 12-sentence

In this lab, the focus was to study muscular fitness. In muscular fitness, there are two main components of measurements that are being taken, which are muscular strength and muscular endurance. Muscular strength is an individual’s ability to exert their maximum force. To test muscular strength, there are multiple tests such as 1 RM , Static Handgrip Strength, and Back Strength Dynamometer test. Muscular endurance is an individual’s ability to sustain prolonged muscular contractions. Tests that reveal results about an individual’s muscular endurance would be tests such as YMCA Submaximal Bench Press, Push-Up, and Plank test. It is important to remember that there is no single test for endurance and strength that will tell an

The aim of the experiment is to find out how or if height affects lung capacity

During each phase of the study, the amount of pressure being released from the lungs, along with the amount of carbon dioxide, was detected to determine whether or not there would be a negative volume produced and potential issues would be faced with

By tracking the respiratory volumes of the lungs the observations from the spirometer showed how well the lungs work when inhaling and exhaling into the device. During normal breathing approximately 500 mL of air is going into and out of the lungs. However, the average may vary due to sex, size, age, and physical condition (Gutierrez, 2014). For instance, individuals suffering from obstructive respiratory diseases, such as asthma and COPD, have narrow airways that produce an obstructive pattern of the spirometer. On the contrary, a restrictive pattern of spirometry occurs if the value for vital capacity is less than the value for an individual’s age, sex, or physical condition (Kenny,

The measuring of flow-volume loops (FVL) in laboratory settings during exercise are becoming increasingly popular to identify the limiting mechanics of ventilation (Johnson, Beck, Zeballos & Weisman, 1999a). The collection of a maximum flow-volume loop (MFVL) through a forced maximal maneuver at rest allows researchers to compare a baseline value with tidal loops obtained during exercise (Johnson et al., 1999a). Dominelli and Sheel state that MFVL provides information on an individual’s capability to produce volume and flow with respect to their mechanical ceilings (2012). Placing the respective tidal loops associated with different exercise intensities within a resting MFVL shows the difference in volumes during exercise and rest. An MFLV maneuver would yield the largest loop; whereas, the resting tidal loop would be the smallest (Johnson, Weisman, Zeballos & Beck, 1999b). Additionally, tidal loops during exercise will fit somewhere between resting and maximal tidal loops; increasing in volume as intensity increases; however, the loops still remain small in comparison to the MFVL (Johnson et al. 1999b). This aforementioned trend observed in healthy individuals during increasingly intense exercise is related to the lack of constraints on ventilation (Johnson et al. 1999b). Major factors responsible for limiting ventilation at rest and during exercise are bronchodilation and bronchoconstriction; these in turn affect total lung capacity (TLC)--a key measure with

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.

Carry out an experiment to measure the heart rate and ventilation rate before, during and after moderate exercise.
