Study start date: September 1, 1998

Actual date on which the first participant was enrolled.

This study will examine the role of temperature in modulating aspects of energy metabolism in human skeletal muscle. Tests will be conducted at rest and during concentric dorsiflexion exercise of the Tibialis anterior (TA) muscle using an existing custom-designed dynamometer in conjunction with mild local heating and cooling. Magnetic resonance spectroscopy (MRS), performed in a 4-tesla whole-body NMR system, will be used to non-invasively measure muscle temperature and energy-state. Specifically these tests will assess the extent to which temperature changes occur during aerobic exercise and how small temperature changes affect mitochondrial function in-vivo.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details

17 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Treatment Study

These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.
