本研究は,サッカーの攻撃方向を伴うボールポゼッショントレーニングにおける集団変数とテクニカルプレーに対する競技水準の影響を明らかにすることを目的とした.22 名の大学男子サッカー選手を,レギュラー群(N = 11)および非レギュラー群(N = 11)に分けて,同一のオーガナイズで攻撃方向を伴うボールポゼッションを行わせた.ポゼッションのオーガナイズは,縦12m 横24m のコート内で4 対4 を行い,両端の短辺に2 人,コート内に1 人のフリーマンを配置した.テクニカルプレー(コントロールミス,パス本数,パッキングレート)は,記述分析で定量した.選手の位置は,ローカルポジショニングシステムによって記録された.選手の位置から攻撃および守備チームの面積を算出した.パッキングレートは,レギュラー群のほうが非レギュラー群よりも高かった.パス本数は,レギュラー群のほうが非レギュラー群よりも多い傾向であった.競技水準に関わらず,攻撃時の面積は守備時の面積よりも広かった.攻撃時の面積は,非レギュラー群よりもレギュラー群のほうが大きく,守備時の面積は,レギュラー群のほうが非レギュラー群よりも小さかった.本研究の結果は,攻撃方向を伴うボールポゼッションを同一のオーガナイズで実施した場合,レギュラー群のほうが非レギュラー群よりもパッキングレートが高く,それは攻撃時にボールを受けるための位置による違いである可能性が示唆された.

Here, in comparison with community-dwelling middle-aged and older men, we investigated the skeletal muscle mass and bone mineral density of a Japanese alpinist (Mr. A) who, at the age of 80 years, is to date the oldest person to have climbed to the summit of Mount Everest (8,848 m). Using dual X-ray absorptiometry, we determined the appendicular skeletal muscle mass index (SMI), total bone mineral density (tBMD), whole body fat-free mass index (FFMI) and fat mass index (FMI) of Mr. A (84.6 yr) and 209 community-dwelling middle-aged and older men (50-79 yr, mean age: 68.1 yr). The SMI, tBMD, FFMI and FMI were 8.79 kg/m2, 1.075 g/cm2, 22.3 kg/m2 and 9.8 kg/m2, respectively, in Mr. A and 7.46 ± 0.81 kg/m2, 1.020 ± 0.100 g/cm2, 18.1 ± 1.9 kg/m2 and 5.5 ± 1.7 kg/m2, respectively, in the community-dwelling middle-aged and older men. The values in Mr. A were higher than those in the community-dwelling middle-aged and older men, with z-scores for the SMI and tBMD of 1.63 and 0.55, respectively. Mr. A maintained a high skeletal muscle mass and bone mineral density even at the age of 84 years, which may have been attributable in part to his long-term training for mountain climbing.

This study was conducted to examine the reliability of three-dimensional photonic image scanning (3DPS) for measuring body surface area (BSA), and formulate equations for predicting BSA based on 3DPS. The surface area (SA) of a cylinder with known SA and BSA of 7 males were repeatedly measured by 3DPS. BSA was determined by 3DPS for 122 subjects (25–76 yrs). BSA prediction equations for both genders were developed for the validation group (16 males and 45 females) using body height and mass as independent variables, and were cross-validated for the cross-validation group (16 males and 45 females). The standard error of measurement was 2.2cm2 (0.16%). The coefficients of variation (CV) for repeated measurements of SA were less than 0.2%. The BSA of subjects did not differ significantly on any given day nor between days, with a CV of less than 1%. The coefficient of determination and standard error of estimation of the prediction equations were 0.98 and 183cm2 (1.1%), respectively, for males and 0.98 and 204cm2 (1.3%), respectively, for females. There was no significant difference between the predicted and measured values. In the cross-validation group, there was no significant difference between the predicted and measured values without systematic errors. These findings indicate that 3DPS is reliable for measuring BSA, and the formulated equations are valid and applicable to individuals within a wide age-range.

This study aimed to clarify the differences in cardiorespiratory and metabolic responses to body mass-based front lunge and squat exercises with relation to muscular activity. Seven healthy adult males performed 200 times body mass-based squat and front lunge exercises. During the exercises, oxygen uptake, heart rate (HR), blood lactate concentration (La), ground reaction force were measured. Oxygen uptake was divided by body mass (VO2). VO2 and HR was normalized to maximal VO2 (%VO2max) and maximal HR (%HRmax) obtained from an incremental load test. Electromyograms (EMGs) during the two exercises were recorded from the vastus lateralis (VL), rectus femoris, vastus medialis (VM), biceps femoris, gluteus maximus (GM). EMG amplitudes during both exercises were normalized to those during maximal voluntary contraction, and expressed as relative value (%EMGMVC). Time that cardiorespiratory parameters became stable was 4-6 min in both exercises. VO2, %VO2max, metabolic equivalent, were higher in the front lunge than the squat. No significant differences in HR, %HRmax and La were found between both tasks. %EMGMVC in VL, VM and GM were higher in the front lunge than the squat. These current findings indicate that 1) body mass-based squat and front lunge exercises are physiologically of more than moderate intensity, and 2) the cardiorespiratory responses to body mass-based front lunge are greater than those to body mass-based squat. This may be due to the difference in muscular activities of VL, VM and GM during the tasks.
