Researchers at McMaster University in Hamilton, Ontario, sent two groups of cyclists on a 30-K time trial, then put them through different 2-week training schedules (see workouts below). The first group did a 6 to 8-minute sprint workout 3 days a week, while the second group did a long 90 to 120-minute workout 3 days a week. After two weeks of training, the researchers had them do the time trial a second time. Improvement was the same for both groups.
"If people are willing to tolerate the discomfort and fatigue of sprinting, the muscle adaptations can be very profound," says Martin Gibala, Ph.D., the lead study investigator. "In no way are we suggesting to only sprint train, or only perform 6 minutes of exercise a week," he says. "The practical message is that interval-type training can be effective for the general public." According to Gibala, sprinting increases the body's production of citrate synthase, an enzyme that helps muscles use oxygen.
12 minutes of all-out cycling sprints = 10 hours of moderate cycling
GROUP 1 WORKOUT:
Four to six 30-second all-out sprints with 4 minutes of rest between; three workouts a week for 2 weeks, on a stationary bike set at the highest resistance
IMPROVEMENT IN 30-K TIME TRIAL:
About 5-6 minutes
GROUP 2 WORKOUT:
Steady, moderate cycling for 90 to 120 minutes; three workouts a week for 2 weeks, adding up to 10 hours of cycling
IMPROVEMENT IN 30-K TIME TRIAL:
About 5-6 minutes
