“…The subjects were instructed to perform the lunge at the maximal speed possible. Martine et al (1997) and Knapik et al (1996) formulas. For kinematics measurements, a ten-camera system was employed (BTS SMART DX 7000, BTS Bioengineering, Milan, Italy) with a sampling frequency of 250 Virtual markers (midpoint between the ASIS, midpoint of ankle, knee, elbow and wrist, midpoint between the 1st and the 5th metatarsophalangeal joints) were computed post acquisition.…”

The teaching of the lunge technique in fencing is critical in the developmental age. The relations of anthropometrics with kinematics of lunge was studied only in adult fencers, and no study exist in young considering the different level of experience. Our aims were to assess, in young fencers, which factors, between the anthropometric and the kinematics, were mostly connected with lunge performance (speed and excursion) in different genders and expertise levels. Fifteen young fencers participated in this study. Lunge kinematics, anthropometric characteristics and force expressed in vertical jump tests were collected. Maximal lunge velocity resulted mainly correlated with the posterior knee’s extension ((r=0.56, p=0.031). The lunge distance and mean hip velocity were mostly correlated with fencers’ height (r=0.85, p=0.000 and r=0.76, p=0.001) and FFM (r=0.8, p=0.000 and r=0.73, p=0.002). Experts and non-experts show significant differences in fat free mass, area of upper arm, and of thighs (Effect Size = 1,27 – 1,33, p= 0,021-0,035). From our results it emerges that, in this age range, the analysed aspects of lunge performance are mainly correlated with participant’s anthropometry. Moreover, it is already possible in this age span, to find technical differences linked to the experience.

“…Absolute and % fat mass (FM) and fat free mass (FFM) were assessed via bioelectrical impedance (Maltron BF906, Rayleigh, GB), and the body mass index was calculated. The cross-sectional area (CSA) of the forward upper arm was calculated using the formula of Martine et al [12], while the CSA of the thighs was calculated with the formulas of Knapik et al [13].…”

Effect of Gender and Anthropometrics on the Kinematics of the Lunge in Young Foil Fencers (Lunge Kinematics in Young Fencers)

Knowledge of the kinematics of young fencers is important when teaching fencing, but it has been minimally investigated in the literature, especially in young subjects, and further research is needed. Our aims were to assess whether anthropometric factors or kinematic factors are more closely related to lunge performance (speed and range of motion) in young fencers and to investigate gender differences in relation to kinematics. Fifteen fencers participated in this study (8 females and 7 males; age 12.9 ± 2.7 years, height 157.4 ± 15.1 cm, weight 49.7 ± 11.7 kg). Lunge kinematics and anthropometrics were collected with a 10-camera optoelectronic system. Descriptive statistics, bivariate correlation, t-test, and simple regression were performed. Peak lunge velocity was mainly correlated with posterior knee extension (r = 0.56, p = 0.031). The lunge distance and mean hip velocity were mostly correlated with the fencers’ height (r = 0.85, p = 0.000 and r = 0.76, p = 0.001) and fat-free mass (r = 0.79, p = 0.000 and r = 0.73, p = 0.002). Young fencers use a lower limb-driven strategy to perform the lunge, while adults are reported to use an upper limb-driven strategy for the lunge attack. Linear and angular velocities and ranges of motion were lower in young fencers in comparison to those of adults. Based on these results, we suggest a different approach to teaching the lunge action in young foil fencers. The implications of our study are that when teaching the lunge technique to this age group, a different approach for males and females is not required, and that strength is not a discriminant physical quality for the correctness of performance.

Commercial porters of eastern Nepal: Health status, physical work capacity, and energy expenditure

et al. 2001

The purpose of the study was to compare full-time hill porters in eastern Nepal with part-time casual porters engaged primarily in subsistence farming. The 50 porters selected for this study in Kenja (elevation 1,664 m) were young adult males of Tibeto-Nepali origin. Following standardized interviews, anthropometry, and routine physical examinations, the porters were tested in a field laboratory for physiological parameters associated with aerobic performance. Exercise testing, using a step test and indirect calorimetry, included a submaximal assessment of economy and a maximal-effort graded exercise test. Energy expenditure was measured in the field during actual tumpline load carriage. No statistically significant differences were found between full-time and part-time porters with respect to age, anthropometric characteristics, health, nutritional status, or aerobic power. Mean VO2 peak was 2.38 +/- 0.27 L/min (47.1 +/- 5.3 ml/kg/min). Load-carrying economy did not differ significantly between porter groups. The relationship between VO2 and load was linear over the range of 10-30 kg with a slope of 9 +/- 4 ml O2/min per kg of load. During the field test of actual work performance, porters expended, on average, 348 +/- 68 kcal/hr in carrying loads on the level and 408 +/- 60 kcal/hr in carrying loads uphill. Most porters stopped every 2 min, on average, to rest their loads briefly on T-headed resting sticks (tokmas). The technique of self-paced, intermittent exercise together with the modest increase in energy demands for carrying increasingly heavier loads allows these individuals to regulate work intensity and carry extremely heavy loads without creating persistent medical problems.
