Effect of Aerobic Interval Training With Vitamin D Supplement on Functional Capacity and Perceived Myalgia

Effect of Aerobic Interval Training Combined With Vitamin D Supplement on Functional Capacity and Perceived Myalgia in Middle Aged Obese Women

This study aimed to investigate whether there will be an effect of adding a program of aerobic interval training in managing patients suffering from myalgia associated with vitamin D deficiency.

Forty five women complaining from myalgia with vitamin D deficiency participating in this study. Their ages are ranged from 30 to 40 years. They are assigned randomly into three groups: Group (A): included 15 patients who are participating in an aerobic interval training exercise program with vitamin D supplementation (cholecalciferol 400 IU/day). Group (B): included 15 patients who are receiving vitamin D supplementation only (cholecalciferol 400 IU/day). Group (C): included 15 patients who are participating in an interval training exercise program only. The intervention will last for 12 weeks

Included 15 patients who are participating in an aerobic interval training exercise program with vitamin D supplementation (cholecalciferol 400 IU/day). The aerobic interval training is conducted for one hour, three days per week on a total period of 12 weeks.

Included 15 patients who are receiving vitamin D supplementation only . One capsule containing (cholecalciferol 400 IU) was taken every day for 12 weeks

Included 15 patients who are participating in an aerobic interval training exercise program only. The aerobic interval training is conducted for one hour, three days per week on a total period of 12 weeks.

The participants in both groups A will be instructed to perform aerobic interval exercises at 70% maxHR for 5 minutes and then decrease activity to 50% for 5 minutes and repeat for the length of the activity (the training will be done by using bicycle ergometer(Biodex LBC, Biodex Inc., New York).• Before starting training ; Maximum heart rate calculated from the following equation: maxHR= 220-age . Duration: the first five to ten minutes of each session were dedicated to warming up exercise on the bicycle in the form of slow progression exercise (to decrease the risk of hypotension, musculoskeletal injury and cardiovascular complications), followed by the active phase of exercise for 40 min., and finally cooling down phase for ten minutes. with intensity and speed decreased gradually until reaching the resting HR Frequency: 3 days/week., for 12 weeks Also all participants in this group are taking gne capsule containing (cholecalciferol 400 IU) every day .

The participants in group C will be instructed to perform aerobic interval exercises at 70% maxHR for 5 minutes and then decrease activity to 50% for 5 minutes and repeat for the length of the activity (the training will be done by using bicycle ergometer(Biodex LBC, Biodex Inc., New York).• Before starting training ; Maximum heart rate calculated from the following equation: maxHR= 220-age (Gellish ,2007). Duration: the first five to ten minutes of each session were dedicated to warming up exercise on the bicycle in the form of slow progression exercise (to decrease the risk of hypotension, musculoskeletal injury and cardiovascular complications), followed by the active phase of exercise for 40 min., and finally cooling down phase for ten minutes. with intensity and speed decreased gradually until reaching the resting heart rate (Broderick et al.,2014). Frequency: 3 days/week. The whole training lasting for 12 weeks

A 10-cm Visual Analogue Scale (VAS) was used to evaluate the patients' pain , with 0 representing no pain and 10 representing the worst pain imaginable

The Short form health survey (SF-12)is often used to compare health status between groups of patients, to indentify predictors of health status

Inclusion Criteria: Forty five sedentry women with non specific myalgia pain. The patients' ages ranged from 30 -40 years. All patients have non specific muscle pain for more than 2 months. They have vitamin D deficiency. All patients have BMI from 25 to 34.9 kg/m2. All patients were clinically and medically stable when attending the study. Exclusion Criteria: Unstable cardiovascular and chest problems. Patients with diseases which affect vitamin D level as a history of rheumatic or metabolic bone diseases and diabetes. Patients taking drugs which affect vitamin D level as steroids and anticonvulsants drugs . Musculoskeletal disorders which may affect their physical ability to do the exercises.
