This study will compare the effects of a unique form of cycling cross-training on running performance. Participants will be randomly assigned to one of three training groups: a control group (no cycling), traditional cycling, or cycling using the PowerCranksTM. PowerCranksTM cycling requires the user to cycle using independent crank arms, essentially performing simultaneous one-legged cycling for both legs.
The duration of this study is 9 weeks, including a familiarization week, a baseline testing week, 6 weeks of training, and a week of post-training testing. Testing weeks will require the participant to visit the Marywood Human Physiology Lab twice per week. Training weeks will require the participant to visit the Lab three times per week.
Participation is open to men and women:
· Between the ages of 18 and 45
· That have run at least 3 times and 15 miles a week for the last 6 months
· Not of an “elite” level
· That have not regularly participated in cycling the last 6 months
· Who do not have any current injuries or medical conditions that prohibit strenuous exercise
· With a VO2max between the 70th and 95th age based percentile (this will be tested in the lab before the study)
Benefits of participation include:
· Learning more about your fitness level
· Potential improvements in running performance and fitness
· Access to use the unique PowerCranksTM for cross-training
· Adding to the body of scientific knowledge of training research
This study will compare two different form of resistance training on cycling performance and functional movement ability. Participants will be randomly assigned to one of three training groups: control group (no resistance training), traditional resistance training, or a functional training group. The exercises for the functional group are tailored to the specific weaknesses of the athlete, as highlighted by the Functional Movement Screen.
The duration of this study will be 9 weeks, and will consist of a familiarization week, a baseline testing week, 6 weeks of training, and a post-training testing week. Each week will consist of two sessions. The testing sessions will last approximately 1.5 hours and the training sessions will last approximately 1 hour. All testing will be done in the Marywood Human Physiology Lab and at least one of the weekly training sessions will be supervised in the Marywood gym. If the participant has access to the necessary training equipment, the second weekly training session may be done elsewhere.
Participation is open to both men and women. You are eligible for participation if:
· You have been cycling for at least 6 months
· Have completed at least one 6 hour training week in the last 6 months
· Are between 18—45 years old
· Can commit to the 9 week duration
· You have been resistance training for at least 2 months
Benefits of participation include:
· Free exercise testing
· Potential increase in fitness and cycling performance
· Movement analysis
· Contribution to the field of exercise science
The purpose of this study is to investigate the effects of whey protein cherry juice as compared to a placebo on muscle damage and indices of recovery following muscle damaging exercise, as evidenced by changes in physiological variables in skeletal muscle and blood plasma and subjective perceptions of soreness.
It is well documented that both downhill running and long-distance running induce skeletal muscle damage. For this reason, a downhill marathon, namely the ‘Steamtown Marathon’ will represent damaging exercise in this study and serve as a model to test the intervention of whey protein cherry juice on muscle damage. The Steamtown Marathon has net downhill profile (elevation gain/ loss is – 955’) with varying degrees of long downhill stretches.
The markers used to indicate symptoms of muscle damage will include muscle soreness, muscle strength, quadricep skin temperature, quadricep circumference, creatine kinase, lactate dehygrogenase, interluekin-6, interluekin-1b, TNF-α, c-reactive protein, and oxygen radical absorbance capacity. All markers will be assessed at the following time points (1) baseline, (2) 24-h pre-race, (3) 0-h post-race, (4) 60-min post-race, (5) 24-h post-race, (6) 48-h post-race and (7) 72-h post-race.
30 subjects will be recruited from registered participants in the Steamtown Marathon and be screened for exclusion and inclusion criteria. Exclusion criteria will include elite runners, pregnant women, smokers, and those who have had a recent bacterial and viral infection and/or pre-existing chronic disease, orthopedic injury and dairy allergy. Inclusion criteria will include healthy, recreationally trained, endurance runners who are 18-45 years of age. Participants must be willing to maintain a food journal, training log, symptoms record, as well as refrain from engaging in any other form of ergogenic interventions (physiological, pharmalogical, nutritional, and some mechanical) throughout the study.Diahnn Thompkins
