What is CAFT test?

The Canadian Aerobic Fitness Test (CAFT), formerly known as the Canadian Home Fitness Test, is unique in that it was designed to promote fitness testing at home. The CAFT was developed on a sample of 1,544 individuals (699 men and 845 women) aged 15 to 69 years. 44 The CAFT is a measure of fitness and is based on the duration of the step test and a 10-second recovery of HR ( Tabs. 3 and 4 ). Norms for the recovery HR in men and women have been reported, 44 and a “Physical Fitness Evaluation Chart” for various age groups is available ( Tab. 5 ). In addition, Jette et al 45 developed a regression equation for the CAFT to predict V̇ o2 max. A sample of 59 individuals, aged 15 to 74 years, completed the CAFT and then underwent a progressive treadmill test to evaluate V̇ o2 max.

What is submaximal exercise testing?

Compared with maximal exercise testing, submaximal exercise testing appears to have greater applicability to physical therapists in their role as clinical exercise specialists. This review contrasts maximal and submaximal exercise testing. Two major categories of submaximal tests (ie, predictive and performance tests) and their relative merits are described. Predictive tests are submaximal tests that are used to predict maximal aerobic capacity. Performance tests involve measuring the responses to standardized physical activities that are typically encountered in everyday life. To maximize the validity and reliability of data obtained from submaximal tests, physical therapists are cautioned to apply the tests selectively based on their indications; to adhere to methods, including the requisite number of practice sessions; and to use measurements such as heart rate, blood pressure, exertion, and pain to evaluate test performance and to safely monitor patients.

What are submaximal tests?

There are numerous submaximal tests from which to choose. These tests have been developed to meet the needs of people with various functional limitations and disabilities and the needs of older adults. In our opinion, however, inappropriate selection may lead to either understressing or overstressing the individual. Such understressing or overstressing of the person, in our view, can lead to invalid conclusions because of ceiling or floor effects, and the testing may be hazardous. The goal of testing should be to produce a sufficient level of exercise stress without physiologic or biomechanical strain. Factors that we believe should be considered in selecting the appropriate test include the person's primary and secondary pathologies and how these pathologies physically affect the person's daily life. Other factors include cognitive status, age, weight, nutritional status, mobility, use of walking aids or orthotic or prosthetic devices, independence, work situation, home situation, and the person's needs and wants. People who may be medically unstable and at risk for an arrest may need to be tested in the presence of a cardiologist or pulmonary specialist or by a physical therapist in a specialized setting where emergency services are on hand. The population for which a given test was developed, the degree of validity and reliability of measure-ments obtained with each test, and test sensitivity also should be considered ( Appendix ). Reports in the literature on the common submaximal tests described in this article vary with respect to the adequacy of establishing validity, reliability, and sensitivity; thus, test interpretation may be limited. These limitations should be considered in the selection of each test. Physical therapists should determine what information will be added by performing an exercise test and how that information will alter clinical decision making.

What is maximal exercise?

Maximal exercise testing has a role in the assessment of maximal aerobic capacity or functional work capacity. Because people are frequently limited by cardiopulmo-nary, musculoskeletal, and neuromuscular impairments and complaints such as exertion, dyspnea, fatigue, weakness, and pain during their activities of daily living, maximal testing is often contraindicated or of limited value. In people without cardiopulmonary or musculo-skeletal impairments, the reserve capacity of the cardiopulmonary and musculoskeletal systems is thought to be barely tapped during daily activities. 22 In people with pathology, this reserve can be greatly reduced, and a greater than usual proportion of a person's maximal capacity may be needed to perform routine activities. 23

What is the Bruce treadmill test?

The Bruce Treadmill Test and the Modified Bruce Treadmill Test are widely used, especially for the diagnosis of coronary heart disease, and , as a result, normative data are available. Compared with the original protocol, which starts with a large workload, the modified protocol has a more gradual initial workload.

What is a physical therapist?

Physical therapists are clinical exercise specialists who apply exercise as an assessment and diagnostic tool and in treatment. We believe that they should have a thorough knowledge of exercise testing, including submaximal exercise testing.

What is the SPWT 70?

The Self-Paced Walking Test (SPWT) 70 is an exercise test developed for elderly and frail individuals. It consists of free walking at 3 speeds down an indoor corridor (ie, 250 m). Various exercise responses can be assessed such as speed, time, stride frequency, stride length, HR, and predicted V̇ o2 max. The test was developed on 24 individuals aged 64 to 66 years. Ten active students aged 19 to 21 years served as a comparison group. Each subject performed the SPWT and a progressive cycle ergometer test. Only 17 elderly individuals could complete the cycle ergometery test, whereas all of them completed the SPWT.

How does a treadmill test work?

What is a single exercise test?

According to ACE, a single exercise testing session can provide an accurate indication of your current aerobic fitness level, and can be a useful tool for tracking your fitness improvements across a consistent workout program. Regular exercise can decrease your heart-rate response to a given exercise intensity.

What percentage of your heart rate is a submaximal?

The intensity level of the exercise you do before reaching 85 percent of your maximum heart rate is an indirect indication of your aerobic fitness.

What is the best method of exercise testing?

Preferred methods of exercise testing use the stationary bike and the treadmill. Many exercise test styles have been designed for each apparatus, with minor differences. During a typical graded fitness test, your weight, height, blood pressure and heart rate are recorded, and your maximum heart rate is calculated.

What muscles generate power at the knee?

Hip flexor power generation at toe-off to accelerate the leg through the swing phase. At the knee joint, muscles generate force for power absorption: Knee extensors at terminal stance. Knee flexors at terminal swing to decelerated the leg.

How to improve gait and walking?

To improve walking and gait focus on ballistic or fast exercises, and particularly target the calf because it is so important for walking. For example, if you have no resources or are in a home environment, it would be better to do a quick 'calf drop' exercise rather than a controlled calf raise – i.e. raise up onto the toes and then quickly drop down and push up again. Or with access to a mini-trampet the exercise could involve bouncing between alternate heel raises demonstrated in the video below.

What is paresis in exercise?

How long does it take to push off a muscle?

Push off represents about 0.15 seconds- this is when the achilles tendon is producing most of the power. Strength training can increase the muscle-tendon strength but not the power needed for the push off.

Where is the main power generated in the gait cycle?

At the stance phase, the main power is generated at the ankle, when the plantar flexor generates power at terminal stance for push off. A study analysed the power generated at the ankle joint and found that Achilles tendon produced the highest peak of force. Stance phase makes up about 0.6 seconds of the gait cycle.

Does walking speed affect gait?

In older adults, it has been found that a lower walking speeds reduce gait quality. A minimal level of strength is required in all muscles to generate power for walking, however, not all muscles are recruited equally.

What muscle is used in high speed running?

High speed running requires eccentric strength when the hamstring muscles are in a lengthened state. The lengthened state occurs when the hip is in flexion and the lower leg moves into extension, thus lengthening the two joint hamstring muscle over both articulations upon which they act. There is evidence to suggest that athletes who have sustained ...

What is the H test?

Dynamic hamstring flexibility test (H-test). As an alternative or compliment to the H-test the authors have developed and are currently testing the validity of a manual muscle test to examine hamstring weakness in the lengthened state. Since the hamstring muscle group is a two joint muscle, crossing both the hip and knee joint, ...

Does eccentric strength increase after hamstring injury?

Failing to increase an athlete's eccentric strength in a lengthened position after a hamstring injury may predispose an athlete to subsequent reinjury. Incorporating lengthened state eccentric training may help reduce the rate of reinjury. Level of Evidence:

Exercise is the closest thing there is to a miracle drug, 1 2 and strength training is one of the best kinds of exercise, practically like magic: more healthy and more efficient than most people realize, ...

Does corrective exercise prevent injuries?

The corrective exercise trap: strengthening does not prevent or fix injuries. Tedious, specific, “corrective” or “therapeutic” strengthening exercises are a staple and tired cliché of physical therapy. Everyone assumes their rehab montage will involve a lot of disciplined strengthening of specific muscles.
