Summary
Recruiting African-American and white colorectal cancer survivors for exercise programs is difficult. However, participation in supervised aerobic exercise improved quality of life and exercise capacity, with similar barriers reported by both groups.
Area of Science:
- Oncology
- Exercise Physiology
- Public Health
Background:
- African-American (AA) colorectal cancer (CRC) survivors exhibit higher rates of obesity and lower physical activity levels compared to white survivors.
- Addressing these disparities is crucial for improving survivorship outcomes.
Purpose of the Study:
- To assess the feasibility of a supervised aerobic exercise program for AA CRC survivors.
- To explore perceptions and barriers related to supervised exercise among AA CRC survivors.
Main Methods:
- A 12-week prospective supervised aerobic exercise intervention using a cycle ergometer.
- Quantitative assessments included cardiorespiratory fitness (VO2peak), 6-minute walk test (6MWT), and validated quality of life/symptom questionnaires.
- Qualitative interviews explored barriers and facilitators to exercise participation.
Main Results:
- Enrollment was low, with 4 AAs (3.2%) and 5 white survivors (4.5%) completing the intervention.
- Significant improvements were observed in peak exercise capacity (p=0.011) and quality of life (SF-36, p=0.035) post-intervention.
- Qualitative findings identified co-morbidity, motivation, and location as primary barriers for both AA and white CRC survivors.
Conclusions:
- Supervised exercise interventions show potential benefits for CRC survivors' quality of life and exercise capacity.
- Recruitment into exercise programs remains a significant challenge for CRC survivors across racial groups.
- Understanding and addressing shared barriers is essential for future exercise interventions in cancer survivorship.

Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

01:30Mixing Concrete
383
Concrete mixing ensures a homogenous blend where aggregates are well-coated with cement paste. Concrete mixing is typically done using two main types of mixers: batch and continuous. Batch mixers handle one batch at a time, thoroughly combining materials before discharging and receiving the next batch. In contrast, continuous mixers receive a steady flow of ingredients, mixing them consistently and discharging without interruption. Within batch mixers, tilting drum mixers mix with internal...

01:19Mixing Time
483
The concept of mixing time is significant in producing a uniform concrete mix with the required strength. The mixing period starts once all components are in the mixer. Initially, the mixer is charged with 10% of the water, followed by the consistent addition of solids and then 80% of the water. The remaining water is added later, within the first quarter of the mixing period. The minimum mixing time varies according to the mixer's capacity; for example, mixers with up to 1 cubic yard...

01:27Exercise and Muscle Performance
2.4K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.

01:26Ready Mixed Concrete
368
Ready-mixed concrete, also known as pre-mixed concrete, is prepared in a centralized plant and then transported in trucks to construction sites where it is ready for placement. This type of concrete is categorized into central-mixed, truck-mixed (or transit-mixed), and shrink-mixed. Central-mixed concrete is entirely prepared at a plant and moved to the site in agitator trucks that rotate at a speed of 2 to 6 rpm. Truck-mixed concrete, on the other hand, has the ingredients batched at the plant...
