Resistance Training for the Reduction
of Sports Injury
Fleck and Falkel (1986) state:
"Proper technique and completion of a full
range of motion is paramount to prevent injury to connective
tissue, muscle, and joint capsules. The exercises also should
be conducted in a manner that stimulates the actual athletic
activity as specifically as possible. This may require modifying
the equipment, starting position and/or speed
of contraction. Sets and repetitions should accommodate the
needs of the particular athletic activities with emphasis on
improvement in muscular strength, muscular endurance, or muscular
power. As in any weight training session, warm-up
is essential before a session, even if the resistance training
activity will only involve a relatively light load. Finally,
need to be instituted along with the strength training in order
to keep the optimal functional range of motion throughout the
Weight Lifting Injuries
Rhea (2003) suggests there is no practical difference in injury
rate between using free weights or machines in healthy adults.

adult fitness activities. Am J Sports Med, 21(3):461-7.
Injuries sustained during weightlifting training and weightlifting
competition are substantially lower than injuries incurred from
other sports such as football, gymnastics, or basketball.

In college football players, time lost from injuries during
weight training amounted to 1% of the time lost from injuries
during football participation.

Injury Potential of Weight Training
Weight training injury rates are low.
- General Population (Powell et al. 1998)
- Athletes (Hamill 1994, Zemper 1990)
Free weights do not produce more injuries, compared to machines
(Ralph et al. 1993).
Weightlifting injuries are lower than those sustained in other
sports (Hamill 1994, Stone 1990, Stone et al. 1993).

can improve knee stability. The stresses placed upon the joints
and muscles during closed- chained movements are more functional
and offer more natural stresses on the body as compared to open-chain exercises like
extensions. See Hamstring

Upright Row Safety
shoulder width grip is suggested when performing the upright
row. The greater internal rotation required for a close grip
upright row decreases the subacromial space (area between the
greater tubercle of the humerus and acromioclavicular joint).
This may potentially impinge the supraspinatus
tendon and the subacromial bursa (a protective sac of fluid cushioning
the bone from the tendon). A wider grip allows for more space
between the shoulder joint and the head of the humerus allowing
for more clearance of the underlying structures. For the same
reason, when performing a one
arm upright row, keep the elbow pointing directly to the
side, instead of angling it slightly to the front. Shoulders
should be kept back since scapula
protraction can decrease width of subacromical space, possibly
increasing risk of subacromical impingement (Solem-Bertift E,
et al. 1993). An upright posture with chest high and shoulders
back, bar kept close to the body, and a medium to slightly wide
grip can facilitate a more ideal shoulder posture.
The subacromial space as well as other biomechanical and biometric
factors vary from person to person so some individuals may be
more prone to complications while others report no problems performing
the narrower grip upright row. Also see Over

Weight Training for Cardiac Patients
Previously, cardiac patients were cautioned against strength
training for fear that exertional blood pressure elevation would
lead to arrhythmia, or myocardial ischemia. Rehabilitation thus
consisted of mostly aerobic exercises. Multiple studies have
shown that not only is this false, but that resistance training,
as compared to aerobic training not only improved strength and
cardiovascular endurance, but also had fewer cardiovascular complications
of angina, arrhythmia, ischemia, or blood pressure abnormalities.
Moreover, the patients achieved significant muscle strength to
return to their occupational and leisure activities.
