To improve cardiorespiratory endurance6/30/2023 Participants were assigned to either the stair-climbing intervention ( n = 12 male/female = 3/9, age = 20.0 ± 1.8 years body mass index = 21.9 ± 5.0 kg/m 2 mean ± SD) or a nontraining control group ( n = 12 male/female = 2/10, age = 19.3 ± 1.6 years body mass index = 23.8 ± 2.6 kg/m 2) using a block randomization scheme and block size of 2 to ensure an equal number of subjects in each group. Exclusion criteria were: diagnosed cardiometabolic disease, smoker, and answering “yes” to any of the questions on the GAQ form. Inclusion criteria were deemed healthy based on the Canadian Society for Exercise Physiology (CSEP) General Activity Questionnaire (GAQ) ( CSEP 2017) and inactive as determined by a self-report of less than 1 h of structured physical activity per week using the International Physical Activity Questionnaire ( Craig et al. Twenty-four young adults were recruited primarily from the student population at McMaster University. We hypothesized that, as compared with a nontraining control group, a protocol involving 3 daily bouts of vigorously ascending a 3-flight stairwell (60 steps), with 1–4 h recovery, would enhance CRF when performed 3 days/week for 6 weeks. (2017) however, in contrast to the original protocol, the 3 bouts of stair climbing were separated by a few hours of recovery, as compared with being performed in a single session with a few minutes in between bouts. The design of the present study was modelled after work by Allison et al. It is unknown if SIT exercise snacks, or brief bouts of vigorous exercise performed as single sprints spread throughout the day, is a sufficient stimulus to improve CRF. A training program involving three ∼12-min bouts of intermittent interval exercise was superior to a single daily bout of energy-matched continuous exercise for improving blood sugar control in people with insulin resistance ( Francois et al. (2014) coined the term “exercise snacks” to describe breaking up a single session of continuous exercise into several shorter bouts spread throughout the day. Increasing your workout times in small increments every few days, or in five-minute blocs every week, after your cardiorespiratory system has become conditioned to your current workout, are both viable options for increasing your workouts.Francois et al. You may not want to increase your time each session, to give your body a chance get used to the work you're doing before trying to work harder. If you are working at an intensity level that challenges, but does not physical fatigue you, keep track of the exact number of minutes you exercise each time you work out and set goals for increasing your time. Similar to distance goals, time goals let you keep track of increases in the amount of exercise you're doing by monitoring the number of minutes you work. Many machines such as treadmills have digital monitors that let you track your distance. While you are building your cardio fitness, keep track of how many blocks you power walk, or how many miles you cycle, roller blade or workout on an exercise machine. You may be able to increase the length of your less strenuous exercise, which will help you increase endurance. If you are just starting out with exercise, you may not be able to increase the intensity of your exercise for a week or more. If you are new to exercise, use goals to help you build your endurance. This helps you perform activity during a match or game, or helps you perform a longer exercise workout, such as a 30-minute aerobic exercise routine. Endurance is your ability to perform physical activity over time. Certain types of exercise helps you improve your cardiovascular strength, or capacity, while others help you improve your endurance, or stamina.
