“…The severity of dyspnea was also significantly different between the 2 types of exercise and was increased during stationary cycle exercise. It has been demonstrated that interval training allows work of maximal intensity to be performed with a relatively low perception of dyspnea compared with continuous training 26 and produces similar improvements in exercise performance and quality of life. 27 The game playing used in our study involves the whole body, as opposed to stationary cycling, which involves predominantly the lower limbs.…”

Active Video Game Playing in Children and Adolescents With Cystic Fibrosis: Exercise or Just Fun?

BACKGROUND: Xbox Kinect has been proposed as an exercise intervention in cystic fibrosis (CF), but its potential has not been compared with standard training modalities. METHODS: Using a crossover design, subjects were randomized to 2 intervention groups: Xbox Kinect and a traditional stationary cycle. Heart rate, S pO2 , dyspnea, and fatigue were measured. Subject satisfaction was tested. RESULTS: Thirty subjects with CF (11 males, mean ؎ SD age of 12 ؎ 2.5 y, mean ؎ SD FEV 1 of 73 ؎ 16% of predicted) were enrolled. Xbox Kinect provided a cardiovascular demand similar to a stationary cycle, although the modality was different (interval vs continuous). Maximum heart rates were similar (P ‫؍‬ .2). Heart rate target was achieved more frequently with a stationary cycle (P ‫؍‬ .02). Xbox Kinect caused less dyspnea (P ‫؍‬ .001) and fatigue (P < .001) and was more enjoyable than a stationary cycle (P < .001). CONCLUSIONS: Subjects preferred Xbox Kinect for its interactivity. Xbox Kinect has the potential to be employed as an exercise intervention in young subjects with CF, but investigation over longer periods is needed.

“…This is a common approach to be able to train at relatively high work rates. Others have shown that COPD patients achieve higher work rates during interval training when compared with continuous training [18]. During treadmill walking, most of the patients tolerated longer blocks of continuous exercise, even with increments in walking speed and duration.…”

Exercise training is an essential component of pulmonary rehabilitation. However, the cardiopulmonary stress imposed during different modalities of exercise training is not yet known.In the present study, the cardiopulmonary stress of a 12-week exercise training programme in 11 chronic obstructive pulmonary disease (COPD) patients (forced expiratory volume in one second 42¡12%pred, age 69¡6 yrs) was measured. Pulmonary gas exchange and cardiac frequency (fC) of three training sessions were measured with a portable metabolic system at the beginning, mid-term and end of the programme. Symptoms were assessed with Borg scores.The exercise intensity was compared with the recommendations for exercise training by the American College of Sports Medicine (ACSM). Training effects were significant (maximum change in work: 14¡11 Watts, 6-min walk test: 44¡36 m). Whole body exercises (cycling, walking and stair climbing) consistently resulted in higher cardiopulmonary stress (oxygen uptake (V9O 2 ), minute ventilation and fC) than arm cranking and resistance training. Dyspnoea was higher during cycling than resistance training. Patients exercised for .70% (.20 min) of the total exercise time at .40% of the V9O 2 reserve and fC reserve (''moderate'' intensity according to the ACSM) throughout the programme.The cardiopulmonary stress resistance training is lower than during whole-body exercise and results in fewer symptoms. In addition, exercise testing based on guidelines using a fixed percentage of baseline peak performance and symptom scores achieves and sustains training intensities recommended according to the American College of Sports Medicine.

“…Health practitioners have previously avoided using interval training in the past due to concerns over increased heart rates and stress which are held at an even level during constant cardiovascular training sessions in comparison. With recent research supporting the use of interval training for increased cardiovascular effect [6,7], patients with COPD [8,9], and fat oxidation [10] health practitioners may need to reconsider the use of interval training methods in other low risk populations. The aging population is one such group of people who are looking for ways to maintain good health and participate in a range of fitness activities and evidence suggests these leisure-time activities are an important promoter of health [11].…”

Objectives: The objective of this study was to compare response; specifically oxygen consumption; of a single bout of exercise using two different (constant and interval) intensity protocols in an aged population.Design: Ten males (68.8 ± 3.7 years) and six females (66.2 ± 3.5 years) were recruited for this study. All participants were actively involved in three hours of physical activity per week and were able to use a cycle ergometer unaided. Methods:Participants completed two randomised 20 min exercise protocols on a cycle ergometer, each with equal work output. The constant intensity session was at 50% of Vo 2max , and the 1 min interval session varied from 70% to 30% Vo 2max . Oxygen consumption was measured during the following phases; resting, warm-up, exercise, cooldown and 20 mins post-exercise.Results: Similar values were found when comparing the overall oxygen consumption for the constant and interval protocols respectively. However, significant differences (p<0.05) were found between the two different intensities during the exercise phase. Conclusions:The interval training protocol consumed higher levels of oxygen during the exercise phase when compared to the constant intensity protocol, despite the participants reporting similar RPE. These age-specific differences should be considered for future exercise prescription for this at-risk population.
