“Walk Your Way to Knowing Your VO2max: The Rockport Test."

           The Rockport Walk Test is a submaximal exercise test used to estimate VO2max. The test is based on the relationship between VO2 and heart rate while walking. The test involves walking for 12 minutes at a self-selected pace. The heart rate is then monitored for one minute after completing the walk (Wozniak, 2020). The heart rate is then multiplied by four to estimate VO2max. The Rockport Walk Test is a safe and reliable way to estimate VO2max. VO2 max is an important indicator of your aerobic fitness and can be used to help you customize your workout intensity and duration. VO2 max can also be used to help predict your race times and monitor your training progress.

Gender has a large influence on VO2max. Men generally have a higher VO2max than women. This is due to differences in body composition, hormones, and muscle mass. Women tend to have more body fat and less muscle mass than men (Santisteban et al., 2022). This difference in body composition results in a lower VO2max. Age also has a significant influence on VO2max. Younger people generally have a higher VO2max than older people. This is because younger people have more muscle mass and less body fat than older people.

 As people age, they tend to lose muscle mass and gain body fat, which results in a lower VO2max. Body composition has a large influence on VO2max. People with more muscle mass and less body fat tend to have a higher VO2max than those with less muscle mass and more body fat. This is because muscle is more efficient at using oxygen than fat. Therefore, people with more muscle mass and less body fat can use oxygen more efficiently, resulting in a higher VO2max.

To obtain the walk value, the tester walks for 12 minutes at a self-selected pace. The tester covers as much distance as possible in 12 minutes. The walk value is the distance covered in the 12 minutes. After completing the Rockport Walk Test, the value obtained was 2.78 km, below the average of 3.2 km for my age group (18-29 years old). The result was expected to be lower than the average, as I am not a very active person.

The Rockport Walk Test is a quick and easy way to estimate VO2max. However, there are some limitations to the test. First, the test is only an estimate of VO2max and is not as accurate as more strenuous and expensive tests. Also, the test is only an estimate of VO2max during submaximal exercise, so it does not provide information about VO2max during maximal exercise.

Olympic Weightlifting Snatch Technique

Image
  Subject Identification Professional Subject: Wes Kitts is a USA Olympic Weightlifting Team member who competed in the Tokyo 2020 Olympics, demonstrating elite-level technical proficiency in the snatch lift through international competition performance. Data Collection Methods For this biomechanical analysis, I have chosen high-definition, slow-motion video clips of the Olympic snatch performance obtained from the official USA Weightlifting YouTube channel. The analysis process involves using screen capture software to extract specific frames that highlight five critical phases of the movement: setup position, first pull, transition phase, second pull, and catch position. Every phase will be recorded in the video so that we can perform a frame-by-frame analysis to allow the measurement and tracking of joint angles, bar path, and body positioning during movement. Documentation entails procedural writing whereby observations are recorded in a planned approach based on the Co...
