We investigated EA status, nutritional and food group intake, bone metabolism using biochemical analysis, and evaluated body composition and bone parameters using dual-energy X-ray absorptiometry. Fifty-two Japanese female athletes (Age: 20.0 ± 1.2 years) were enrolled in this study. Group differences between the low EA (EA < 30 kcal/ kg FFM/d, n = 22) and moderate EA (EA ≥ 30 kcal/kg FFM/d, n = 30) groups were examined. Compared to the moderate EA group, the low EA group exhibited a lower daily intake of protein (g/kg BW), carbohydrate (g/kg BW), calcium (mg), grains (g), meats (g), milk and dairy products (g). Moreover, the bone resorption marker was significantly higher in the low-EA group. The daily intake of soybean products (g), vegetables (g), fish and shellfish (g) and milk and dairy products (g) correlated positively with daily calcium intake (mg). Female athletes with low EA and insufficient intake of milk and dairy products exhibited increased serum tar-trate-resistant acid phosphatase 5b levels. As with milk and dairy products intake, consumption of various food groups was also significantly positively correlated with calcium intake. These findings suggest that a diet with sufficient energy and multiple food groups to provide adequate calcium may benefit bone health among Japanese female athletes.","PeriodicalId":55847,"journal":{"name":"Journal of Physical Fitness and Sports Medicine","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47898083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twelve female handball players (age: 20.1 ± 1.2 years, height: 164.3 ± 4.2 cm, and weight: 61.8 ± 4.1 kg) belonging to the first division of a university league were included in the study. The training load was investigated over a nine-week period of the competition phase. The subjective load indicator was the session rating of perceived exertion (sRPE), and the objective load indicators were total distance, Player Load™, and heart rate-based training load (HRTL). We observed 20.5 ± 2.3 sessions for each player. The sRPE demonstrated significant relationships ( p < 0.05) with all objective load indicators, with correlation coefficients r = 0.73 ± 0.09, 0.73 ± 0.08, and 0.75 ± 0.10 for total distance, Player Load™, and HRTL, respectively. All the relationships were very strong (0.7 < r < 0.9). These results reveal the potential validity of sRPE use in handball and suggest that the sRPE is an indicator that reflects the characteristics of both biomechanical and physiological load indicators.","PeriodicalId":55847,"journal":{"name":"Journal of Physical Fitness and Sports Medicine","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48629631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Soccer related injury and pain data were collected daily in June 2016 25 thorough October 2017 involved in 76 amateur soccer players from two teams. Overall injury 26 incidence was 69 injuries and 2.72/1000 player hours. Acute injuries were 52 (2.05/1000 player 27 hours) and 17 chronic injuries were 0.67/1000 player hours. Most of acute injuries occurred in 28 game period (1.99/1000 player hours). In terms of body regions, ankle (27.5%) was the most 29 common, followed by knee (15.9%), and Thigh (9.0%). Pain incidence was reported 1042 30 (41.10/1000 player hours). The highest pain incidence was reported in game period (36.9/1000 31 player hours).

The purpose of this study was to investigate the effect of exercise intensity on CAR among 14 healthy male university students. Participants rested for 20 min (control condition) and exercised on a cycle ergometer for 20 min at 40% (low), 60% (moderate), and 80% (high) intensity of V・O2max on separate days. Saliva samples were collected 10 times as follows: 1) before and 2) immediately after the experimental session, 3) 10 min, 4) 20 min, and 5) 30 min into the recovery period, 6) 9 PM and 7) 11 PM in the evening following the session, 8) immediately after awakening, 9) 15 min, and 10) 30 min post-awakening the day after the session. Cortisol concentration increased after the high-intensity exercise and recovered in the evening following the session. The 30 min post-awakening sampling point the day after the session of high-intensity exercise was higher than the control condition (p = .039). In addition, the higher intensity exercise condition led to the magnitude of change in CAR (CARc) (p = .006) and the area of cortisol increased under the curve (AUCi) (p = .034), making it higher than the control condition. There were no significant differences in other confounders. These results suggest that CAR showed a higher value in healthy male university students the day after performing high-intensity exercise.","PeriodicalId":55847,"journal":{"name":"Journal of Physical Fitness and Sports Medicine","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41992500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the effect of IM on the mechanism of O2 supply to mitochondria in muscle tissue during muscle contraction is unknown, especially the contribution of myoglobin (Mb) to mitochondrial respiration. This study investigated whether IM causes a delayed response of intracellular Mb saturation (SmbO2) and decreased muscle oxygen uptake (mV・O2) due to elevated intracellular oxygen tension (PmbO2) in contracting muscles using a rat hindlimb perfusion model. Three-week IM decreased the O2 release rate from Mb at the onset of muscle contraction (IM: 3.2 ± 0.9 vs. control (Con): 7.5 ± 2.9 10-2 μmol g-1 min-1; p < 0.05) and state 3 of mitochondrial respiration in muscle tissue (IM: 0.021 ± 0.006 vs. Con: 0.030 ± 0.009 10-3 μM g-1 sec-1; p < 0.05). Despite the increase in mV・O2, the steady-state level of SmbO2 was higher during muscle contraction in the IM group, resulting in elevated PmbO2 (IM: 4.2 ± 1.0 vs. Con: 2.1 ± 1.0 mmHg; p < 0.05). In conclusion, IM decreased the O2 release rate from Mb; this alteration could be associated with mitochondrial dysfunction. These changes within muscle cells may be related to the delayed tissue response seen with near-infrared spectroscopy at the onset of muscle contraction.","PeriodicalId":55847,"journal":{"name":"Journal of Physical Fitness and Sports Medicine","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41810906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
