Athletes are constantly looking for ways to increase their lung capacity. The larger the lung capacity, the more air, specifically oxygen, can be taken in by the athlete. Thus, increasing lung capacity increases endurance, allowing athletes to perform at a higher level for longer periods of time without feeling tired. If lung capacity remains the same while duration or intensity of activity increases, oxygen intake remains the same and there is more stress on the heart to get more oxygen to muscles and remove waste (Rathi 2014). This study will test breath hold time and vital capacity in order to indirectly test endurance. Researchers have not previously explored the comparison between swimmers and soccer players before, so that is what this research intended to do. How long someone can hold their breath is indicative of how much oxygen they can take in which is important in improving endurance. Vital capacity is defined as the largest amount of air that can be maximally expired after a maximal inspiration (Al-Madfai Z. et al 2016). Vital capacity can be used to explain breath hold time by measuring the maximum amount of air that can be inhaled and expelled. Additionally, this study will measure respiratory rate. This study will attempt to determine whether systematic training used by swimmers does result in higher vital capacity and breath hold values compared to soccer players who use an interval style of training, and non-athletes, who have no training program. If this is true, the second phase of the study would go on to test whether systematic training is effective in increasing vital capacity and breath hold (and thus endurance) in soccer players and non-athletes. This could inform one group better ways to train and improve their vital capacity and therefore their endurance.
