“…Some studies have highlighted technical problems that cause errors in estimating the vertical jump height (Dias et al, 2011;Ditroilo et al, 2011;Nuzzo et al, 2011;Farias et al, 2013). However, several important factors have not really been considered and will be discussed below.…”

“…Sargent (1921), the vertical jump has been a commonly used method of assessing muscular power in the lower limbs (McLellan et al, 2011;Quagliarella et al, 2011;Shalfawi et al, 2011;Perez-Gomez & Calbet, 2013). The maximum jump height achieved by an individual, which is an indicator of leg muscular power, can often provide key information regarding their functional capacity (Ditroilo et al, 2011;Gonz alez-Rav e et al, 2011;Amonette et al, 2012;Farias et al, 2013) and performance in many sports (Gabbett, 2002;Duncan et al, 2006;Borr as et al, 2011;Ransdell & Murray, 2011). Over the years, many methods have been proposed to perform this test, including the Sargent jump (Nuzzo et al, 2011;Ransdell & Murray, 2011;Buckthorpe et al, 2012), contact mat (Dias et al, 2011;Nuzzo et al, 2011;Buckthorpe et al, 2012;Kenny et al, 2012), video camera (Dias et al, 2011;Picerno et al, 2011), force plate (Dias et al, 2011;Salaj & Markovic, 2011;Buckthorpe et al, 2012) and, more recently, optical system (Glatthorn et al, 2011).…”

The purpose of this study was to compare three methods to assess vertical jump height, to determine their limitations and to propose solutions to mitigate their effects. The chosen methods were the contact mat, the optical system and the Sargent jump. The testing environment was designed such that all three systems simultaneously measured the vertical jump height. A total of 41 kinesiology students (18 women, 23 men, mean age 23·2 ± 4·5 years) participated in this study. Data show that the contact mat and the optical system essentially provide similar results (P = 0·912) and that the correlation coefficient between the two systems was 0·972 (r(2) = 0·944). However, it was found that the Sargent jump has a tendency to overestimate the height, providing a measurement that is significantly different from the other two methods as the jumps are higher than 30·64 cm (P = 0·044). Through the design of the experiment, several sources of errors were identified and mathematically modelled. These sources include optical sensor placement, flat-footed landing and hip/knee bend. Whenever possible, the errors were quantified and solutions were proposed.

“…The height of the vertical jump was calculated using JUMPING PRO software (Sports Timing Systems, http://www.sportstimingsystems.co.uk/) from the flight time measured in each attempt. Individuals stepped on the contact mat and put their feet in a lateral position aligned with their hips, hands around the waist 25. Volunteers were asked to perform four attempts of a countermovement vertical jump with rest intervals of 40 seconds between trials.…”

PurposeTo compare the metabolic parameters, flexibility, muscle strength, functional capacity, and lower limb muscle power of elderly women with and without the metabolic syndrome (MetS).MethodsThis cross-sectional study included 28 older women divided into two groups: with the MetS (n = 14; 67.3 ± 5.5 years; 67.5 ± 16.7 kg; 1.45 ± 0.35 m; 28.0 ± 7.6 kg/m2), and without the MetS (n = 14; 68.7 ± 5.3 years; 58.2 ± 9.9 kg; 1.55 ± 0.10 m; 24.3 ± 3.8 kg/m2). Body composition was evaluated by dual-energy X-ray absorptiometry and dynamic muscle strength was assessed by one-maximum repetition (1RM) tests in leg press, bench press and biceps curl exercises. Six-minute walk test, Timed Up and Go (TUG); 30-second sitting-rising; arm curl using a 2-kg dumbbell, sit-and-reach (flexibility), and vertical jump tests were performed.ResultsThere was no difference between groups regarding age (P = 0.49), height (P = 0.46), body fat (%) (P = 0.19), systolic (P = 0.64), diastolic (P = 0.41) and mean blood pressure (P = 0.86), 30-second sitting-rising (P = 0.57), 30-s arm curl (P = 0.73), leg press 1RM (P = 0.51), bench press 1RM (P = 0.77), and biceps curl 1RM (P = 0.85). However, women without the MetS presented lower body mass (P = 0.001), body mass index (BMI) (P = 0.0001), waist circumference (P = 0.02), waist-to-height ratio (P = 0.02), fat body mass (kg) (P = 0.05), lean body mass (kg) (P = 0.02), blood glucose (P = 0.05), triglycerides (P = 0.03), Z-score for the MetS (P = 0.05), higher high-density lipoprotein-cholesterol (HDL-C) (P = 0.002), better performance on TUG (P = 0.01), flexibility (P = 0.03), six-minute walk test (P = 0.04), vertical jump (P = 0.05) and relative muscle strength for leg press (P = 0.03), bench press (P = 0.04) and biceps curl (P = 0.002) exercises as compared to women with the MetS.ConclusionElderly women with the MetS have higher metabolic risk profile and lower functional capacity, muscle strength, lower limb power and flexibility as compared to women without the MetS. The evaluation of functional capacity may help to determine the degree of physical decline in older persons with the MetS, while exercise interventions should be encouraged.

Background: Vertical jumps can be used to assess neuromuscular status in sports performance. This is particularly important in CP Football because the players are exposed to high injury risk, but it may be complicated because the gold standard to assess jump performance is scarce in field evaluation. In this case, field techniques such as mobile apps have been analysed to solve this problem. Objectives: The present study aims to evaluate the reliability of the measures of the MyJump2™ app to assess vertical jump performance in professional CP Football. Methods: We assessed 40 male CP Football athletes (28.1 ± 1.4 years, 72.5 ± 6.2 kg and 176 ± 4.2 cm) through the countermovement jump (CMJ) and squat jump (SJ) using a contact mat. At the same time, we assessed the athletes using the MyJump2 ™ application. Results: There were no significant differences between the instruments in the SJ height (P = .12) and flight time (P = .15). Additionally, there were no significant differences between the instruments for CMJ in the jump height (P = .16) and flight time (P = .13). In addition, it was observed that there were significant and strong intraclass correlations in all SJ variables varying from .84 to 0.89 (P < .05), which was classified as "almost perfect". Similar results were observed in all variables from the CMJ, varying from .91 to 0.92 (P ≤ .05). Conclusions:We conclude that the MyJump2 TM app presents high validity and reliability to measure jump height and flight time of the squat jump and the countermovement jump in CP Football athletes.

Reliability of Vertical Jump Performance evaluated with contact mat in elderly women

Abstract: In physically active elderly women, VJ evaluation using a contact mat is a reliable method and could be used to estimate jump height. Additionally, the results of this study could serve as reference values in similar samples evaluated with the same procedures.
