Vascular Responses to High vs Low Repetition Resistance Exercise Training in Young Men

Vascular Responses to High vs Low Repetition Resistance Exercise Training in Young Men

This study evaluates the effects of two types of resistance exercise training (higher-repetition, lower load vs lower-repetition, higher load vs control) on regional and local measures of arterial stiffness in trained young men.

Inclusion Criteria:

• Male
• Aged 18-30 years old
• Non-obese (Body mass index less than 30 kg/m2)
• Non-smoker
• Healthy based on questionnaire responses
• Resistance trained (Resistance training > 2 times per week for 2 years, minimum 1 lower body exercise session per week)

Exclusion Criteria:

• Allergies to milk proteins (whey or casein)
• Any acute or chronic illness, cardiac, pulmonary, liver, or kidney abnormalities, uncontrolled hypertension, insulin- or non-insulin dependent diabetes or other metabolic disorders-all ascertained through medical history screening questionnaires
• Arthritic conditions
• Individuals who consume any analgesic or anti-inflammatory drug(s), prescription or non- prescription, chronically will be excluded
• A history of neuromuscular problems
