Introduction to Functional Anatomy and Exercise Physiology lab Report Name Institution Introduction The human body is made up of interconnected systems that work together to produce different body functions. The systems are interdependent of each other hence playing a significant role in every single body function achieved. The human body systems are categorized into three primary divisions; physiology, anatomy, and neurology, based on their functions. Sports and exercises play a significant role in body functioning as they involve a coordination of various body systems. The anatomy is used to understand and predict how the body responds to stimuli and how it is able to maintain conditions in a presence of changing environment. Physiology,…show more content…
One of the key requirements during sports and exercise is the source of energy which is usually derived through various biochemical processes including anaerobic, aerobic, fats, and ATP-CP. These processes require different components hence release different amount of energy over different amount of times. Lactic acid and lactate are some of the important components produced during training and exercises (Graham, 1984). At rest and in a steady-state of exercises, a balance occurs between lactate production and lactate removal in blood. Therefore, when there is an abrupt increase of lactate levels in blood due to intensified exercise it is referred as lactate threshold (Goodwin, Harris, Hernández, & Gladden, 2007). This concept has been used to consistently predict performance in enduring exercises. Due to the importance attached to the lactate production during exercises, various experiments have been conducted in line with this concept (Kravitz, & Dalleck, 2005). Therefore, this lab report will involve testing of lactate levels in blood based on the intensity of exercises carried out by the…show more content…
The Rated Perceived Exertion (RPE) was collected from the participant while the blood lactate was being measured. From the data collected it was observed that the lactate level in the blood increased gradually at the first stages and then more rapidly as the intensity of the exercise increased. The RPE was noted to increase with the the higher loading. The Borg rating was used in the measurement of the RPE which ranges between 6 and 20; 6 implying that no exertion is involved at all and 20 is maximal exertion (Borg, 1998). The RPE was used to measure the intensity of the physical exercise and use it to correlate to the lactate levels in blood. RPE level of 12 to 14 indicates that physical activity is performed at an intensity of moderate levels. RPE is based on self-assessment and therefore, the participant’s accuracy of self-assessment is an important aspect. The increased lactate measurement was as the result of the physical intensity increasing which meant that more lactate was being producing in the blood through the anaerobic process (Lagally et al., 2002). The incremental of blood lactate therefore, indicates that as the intensity of exercises increased, more blood lactate was being produced than it could be removed (Ohkuwa et al., 2009). The increased physical intensity on the body requires more energy hence the increased body functions that involves a
