Summary
This study will test the difference on jump performance after isometric bulgarian split squats (IBSS) and bodyweight deep squats (BDS) in an entire program. Participants will be randomly separated into 2 different groups. One group will be going through a 3 week workout plan with specific (IBSS) designed workouts while the other group will be doing workouts designed around the (BDS). Before the test begins, participants will be tested on their maximum jump performance on the long jump in Inches. In order to measure their long jump, participants will set a line, and from a stationary position jump as far as they can and mark where their feet first landed. If the feet landed staggered from one another, the mark must be measured from the foot closest to the line. They will then be subject to the assigned workout plan and after 3 weeks, their long jump will be tested again. Upon signing up, participants will receive a workout in which they will complete in environments of their choice, and they will receive information on proper form for warm ups, and the exercise themselves. These workouts will happen monday/wednesday/friday for three weeks.
Please email a signed copy of the digital consent form to brockhay000@stu.sumnersd.org before starting. (You may have to make a copy).
You will either be assigned to the IBSS group, or the BDS group.
You will be asked to complete a workout every monday, wednesday and friday for three weeks.
On the first monday and last friday, you will be asked to measure your long jump for the research.
You must complete the warm up every day you workout.
Email me once complete and I will tell you how to report your score.
Thank you for participating, and email me if you have any questions.

Warm Up Plan
20 jumping jacks: Stand up straight. Jump and bring your legs wider than shoulder width apart while simultaneously raising your arms over your head and out making your body into an X shape. Then jump back and stand straight up again, that is one repetition.
20 high knees in place: Stand in place and at a fast pace, raise one knee up to your hip and bring it back down followed by your other knee to your hip and then bring it back down, That is one repetition.
20 side shuffle each way: In an open space, move your left leg laterally away from your body and then bring your right leg closer at a fast pace. That is one repetition and do this for 20 repetitions. Repeat going in the other direction, moving your right leg first followed by your left leg.
10 burpees: Starting by standing straight up, drop down to the floor and perform a pushup. Then return to your feet and from the lower squat position, jump off the ground as high as you can. That is one repetition.
10 lunge twist each leg: Standing in place, bring your left leg out and on the floor creating a 90 degree angle with your knee. Be sure that your left knee is not in front of your left foot. Lower yourself as low as you can without letting your right knee touch the ground. Twist your body then come back up. Repeat with your right leg. That is one repetition.
10 side lunge each leg: Standing in place, bring your right leg out laterally away from you. Leaning in the other direction, lower yourself until you are resting on top of your left leg and then come back up. Repeat with your left leg. That is one repetition.
10 body weight squats: Standing straight up, shoulder width apart with your weight on your heels, lower yourself down to create a 90 degree angle with your legs while keeping your chest up and out, and then come back up again. That is one repetition
30 second quad stretch each leg: Stand straight up, bring your right leg up behind you and grab your foot with your right hand. Hold this for thirty seconds, then repeat with your other leg grabbing with your other hand.
30 second seated figure 4 stretch each leg: Seat yourself in a chair. Plant your left foot in the ground and bring your right leg and put it over your right leg so it is resting on top. Hold this for 30 seconds and repeat with your left leg and your right foot planted in the ground.

While plenty of athletes and coaches workout their legs in various ways to perform the best they can, it is unclear on which leg workout is the most beneficial for athletes.
By understanding if a certain leg workout is vastly superior to the other, it can go on and change how athletes workout their legs, and how trainers design their workouts.
Bodyweight Deep Squat (BDS): Participants will be standing straight up with their feet shoulder-width apart. While putting their weight on their heels, participants will squat down all the way as far as they can go and come back up while being careful not to use their arms as momentum.
Isometric Bulgarian Split Squat (IBS): This is the exercise where participants will have one leg back on a raised platform and standing straight up. The participant will squat on their one leg to a 90 degree angle and will do the same thing to the other leg.
When comparing the BDS with IBSS on maximum jump performance, the IBSS will increase jump score more than BDS because the IBSS is meant to isolate the quadriceps and hamstrings vs. the BDS which resembles more of a compound workout meaning it uses muscles in relation to each other. The muscles being isolated in the IBSS are the same muscles being used in the Standing broad jump.
COVID-19 may prevent this research study from happening in person, which may prevent some of the data from being 100% accurate moving forward.
How does the isometric bulgarian split squat (IBSS) compare to the bodyweight deep squat (BDS) on the maximum jump performance of the standing broad jump (SBJ)?
Seems both squat exercise programs could be used to increase the SBJ
Athletes and trainers may be interested in including these workouts this in their workout routine.
My hypothesis was correct because I predicted that IBSS would improve jump score more and the research indicated that it did. With an average increase of 9 2/3 inches vs. 3 1/2 inches, the IBSS improved jump score in a greater amount.
Some further investigation in this field would take into account diet, hydration, sleep and stress, and how those also affect scores. Completing this research again with more participants would also help the validity of the conclusion.

Significance/important/value of the study
The findings in this study showed that IBS type squats can be more effective at improving the long jump score than BDS, which can be implemented in the fitness world when designing workouts for athletes and trainers.
Subjects were gathered via advertising and social media
Participants were randomly assigned to BDS or IBSS or control group (3 in each)
Participants began by measuring standing broad jump score in inches
Subjects were provided with a workout routine and must warm up every Monday, Wednesday, Friday for three weeks
Participants measured final broad jump score in inches on the last Friday
Results could not be statistically significant because of the small sample size
Based on these participants, IBSS performed slightly better than BDS
Physical activity over a 3 week time period increases broad jump scores more than no physical activity
