OBJECTIVES: I. To evaluate average percentage body weight (APBW) values and
weight-bearing distribution percentages (WBDP) between four common sports
activities in a referent adult population. II. To suggest clinical implications.
DESIGN: Original research study. SETTING: Lerner Sports Center, Hebrew
University, Mount Scopus, Jerusalem, Israel. PARTICIPANTS: Seventy-five
asymptomatic volunteers, mean age=33.5 (19-72) years SD=15.1, mean weight
(kg)=70.7 (43-113) SD=14.1. INTERVENTIONS: Four tests were conducted: 1.
Overground walking (OGW) over a 20 m distance, 2. Overground jogging (OGJ) over a
20 m distance, 3. Treadmill jogging (TJ) at a constant speed of 8.5 km/h for a
15-second interval and 4. Elliptical exercise (EE) for a 20 second period at a
resistance and incline level of 10, and a steady pace within the range of 70-95
steps/min. MAIN OUTCOME MEASURE: The Smartstep weight-bearing gait analysis
system. RESULTS: The APBW value on the entire foot in OGW was 112% (SD=15.57), in
OGJ, 201% (SD=31.24, in TJ, 175% (SD=25.48) and in EE, 73% (SD=13.8). Regarding
WBDP, the swing phase in OGJ and TJ was significantly longer than the stance
phase (p<0.05). OGW resulted in significantly less swing phase compared to OGJ
and TJ (p<0.05). CONCLUSIONS: EE significantly reduces weight-bearing as compared
to other common functional and sporting activities. These findings may assist the
rehabilitation team when considering returning individuals back to early activity
following certain bony or soft tissue pathologies or lower-limb surgical
procedures. This information is also useful from a repetitive loading standpoint
(to prevent overuse injury) or for exercise recommendations for those at greater
risk for exacerbating chronic joint pathology.
