Tyler Rencken U21557382 BGN 310 UNIT 3: FLEXIBILITY EXERCISE (STRETCHING) AND WARM UP A. Exercise prescription for Mrs Slow: Frequency Intensity Time Type Volume Pattern Progression Approximately 2-3 days/week Stretch to the point of discomfort. Light to moderate intensity stretches. Holding a stretch for 30-60 seconds as tolerated. For proprioceptive neuromuscular facilitation (PNF) techniques, a 20-75% maximum voluntary contraction held for 3-6 seconds followed by a 10-30 sec assisted stretch is recommended Focus on gentle static (active or passive) stretches, any dynamic stretches should avoid vigorous movement of Mrs Slow’s lower back as not to worsen pain. Holding stretch for 30-60 seconds to the point of tightness or slight discomfort. Repetition of each stretch exercise 2-4 times. Gradually increase duration of each stretch and number of sets per week as tolerated. Monitor for any changes in lower back pain and adjust accordingly. Warm up Programme: 1. 5-10 minutes of low-impact light-to-moderate intensity cardiorespiratory activities: walking on a treadmill at a speed where the patient is able to speak (talk test) in an effort to increase blood flow and thus body temperature before performing stretching exercises. 2. Followed by 10 mins of light intensity stretches targeting the lower back, such as pelvic tilts and knee to chest stretches. Very gentle exercises are prescribed due to the “moderate risk” category of Mrs Slow and her affected mobility because of her lower back pain. 3. Stretching/Dynamic movements could include knee twists and gentle trunk rotations. Avoid harsh movements of the hip, pelvis and legs such as leg swings as it may cause more harm to Mrs Slow’s lower back. Mrs Slow’s prescription of more static stretching is based off of the fact that she has a prior injury and we do not want to cause too much motion at that lumbar joint in an effort to not aggravate the joint. B. Flexibility programme: Frequency Intensity Time Type Volume Pattern Progression Approximately 2-3 days/week, daily stretching if possible Stretch to the point of discomfort. Light to moderate intensity stretches. Dynamic stretching for 30-60 seconds as tolerated. Dynamic stretching targeting major muscle groups involved in lawn bowling (shoulders, lower back and hip flexors) Holding 2-4 sets of stretches for 30-60 seconds to the point of slight discomfort. Aim to progress to 60 seconds of total stretching time for each flexibility exercise. Repetition of each stretch exercise 2-4 times. Rhythmical dynamic movements. Gradually increase duration of each stretch and number of sets per week as tolerated. Aim to improve flexibility in the hips, shoulders and lower back. Warm-up Programme 1. 5-10 minutes of low-intensity cardiorespiratory exercise: walk on treadmill at 5km/hour to get blood moving and body temperature elevated. 2. Stretching/Dynamic warm up: each set is 30 seconds, 1 minute rest between sets, total of at least 2 sets of each flexibility exercise within 10 mins – shoulder rolls to improve shoulder flexibility/range of motion, lunges for hip flexors and knee mobility, arm circles (forward and backward), as well as lower back stretches such as seated spinal twists. This is crucial as these flexibility exercises target the joints and muscles involved in lawn bowling. More dynamic movements are prescribed for the lawn bowler than Mrs Slow because he is more mobile, has some extent of range of motion, he is just looking to improve on his flexibility. His sport requires him to be more mobile than Mrs Slow who is moderate risk, thus his warm up program includes less static stretching due to his differing physical fitness goals.
