Objectives:
Pediatric intestinal failure (IF) patients are less physically active compared to healthy peers, exhibit an altered body composition and low bone mineral density, which can be improved through physical activity. We assessed the effects of a tailored exercise intervention on physical fitness, nutritional status, and psychological functioning in children with IF.
Methods:
Pediatric IF patients, still on and weaned off parenteral nutrition aged 6-18 years were eligible. Physical fitness ([sub]maximal exercise capacity, amount of physical activity, motor performance, strength, and core stability), nutritional status (body composition, energy expenditure, and laboratory parameters) and psychological functioning (fear, quality of life, fatigue, gastrointestinal symptoms, and self-esteem) were assessed before and after an initial control period and after a 12-week tailored exercise intervention.
Results:
Sixteen participants (median age 12.2 years [10.5-14.6]) underwent baseline assessments, and eight were weaned off parenteral nutrition. Exercise capacity was normal, but the majority (63%) did not meet physical activity guidelines. Motor skills and muscle strength were impaired. Postintervention, exercise capacity in VO2peak did not improve significantly, but workload in watt (p < 0.01), muscle strength in various muscle groups (p < 0.05), core stability (p < 0.05), and self-esteem (p < 0.05) improved. Nutritional status remained unchanged. Baseline motor skills and change in VO2peak were positively correlated (R = 0.66, p < 0.05).
Conclusions:
Our tailored exercise intervention improved muscle strength, core stability, and self-esteem. Most participants do not meet physical activity recommendations and exhibit impaired muscle strength and motor skills, while exercise capacity is normal. Notably, participants with better baseline motor skills showed greater improvements in exercise capacity.

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...

01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

01:26Exercise Stress Test
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.
