Ostojić","doi":"10.1249/01.MSS.0000563079.77371.F7","DOIUrl":"https://doi.org/10.1249/01.MSS.0000563079.77371.F7","url":null,"abstract":"RESULTS: All players gained weight (F: 86.1 ± 13.1 kg; S: 92.0 ± 12.8 kg, p = 0.033) by spring. The weight gain was associated with an increase in percentage body fat (F: 13.8 ± 4.6; S: 16.3 ± 4.4, p = 0.028). All players decreased total caloric intake in the spring (F: 5553 ± 1922 kcal; S: 3972 ± 1384 kcal, p = 0.0008). There were no differences in the macronutrient distribution (%kcal) at either time point (Fat: F: 37.3 ± 5.9%; S: 37.3 ± 9.1%; Carbohydrate F: 47.5 ± 6.8%, S: 46 ± 11.0% Protein F: 15.2 ± 3.8%; S:16.87± 4.5%). The player’s relative protein intake (g/kg) was lower in the off season (F: 2.60 ± 1.36; S: 1.87 ± 0.97; p = 0.036). Sodium and cholesterol consumption decreased from F to S but remained above the daily recommended intake for all players. There were no differences in total calories, macronutrient composition, relative protein intake, sodium or cholesterol between the skilled and unskilled players. A majority of the players meals were consumed at the college dining hall. CONCLUSION: Body weight and percent body fat increased from F to S with an associated increased caloric intake during the season. The players consumed large amounts of calories with a high percentage of fat during the season. All players decreased caloric intake in the off season. The change in body weight and body composition may increase health risks in the long run. It is important for players to make dietary choices to maximize performance and reduce long term health risks within the constraints of eating at the college dining hall.","PeriodicalId":18500,"journal":{"name":"Medicine & Science in Sports & Exercise","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85894428","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}

It was hypothesized that pitchers with MUCL injury would have ˃GIRLoss and TRMD compared to pitchers without MUCL injury, with no differences in IR, ER, TRM, GIRLoss, GERGain, and TRMD. METHODS: Two-hundred-sixteen-male HS, COLL, and PRO pitchers were equally divided into MUCL-injury-group (n=108) and control-group (n=108) without MUCL injury. Controlgroup was matched with the MUCL-injury-group according to number, level &age. Bilateral shoulder passive IR/ER were measured and GIRLoss, GERGain, TRM, and TRMD calculated. A two-way-analysis-of-variance (p<0.05) was employed to assess shoulder-rotational-differences among the two-groups and three-pitching-levels. RESULTS: Compared to control-group, MUCL-injured-group had ˃GIRLoss (21°±14°-versus-13°±8°;p<0.001), GERGain (14°±9°-versus-10°±9°;p=0.004), and TRMD (7°±13°-versus3°±9°;p=0.008). For all pitching levels ~60% of subjects in MUCL-injury-group had GIRLoss>18°, compared to ~30% of subjects in control-group. ~60% of subjects in MUCL-injury-group had TRMD >5°, compared to 50% of subjects in control group. No differences were observed among HS, COLL, and PRO pitchers for GIRLoss (16°±12°,17°±11°,19°±13°, respectively; p=0.131), GERGain (11°±9°,11°±10°,13°±10°, respectively; p=0.171), TRMD (5°±11°,6°±11°,5°±14°,respectively; p=0.711), throwing shoulder ER (111°±10°,111°±11°,113°±9°,respectively; p=0.427), throwing shoulder IR (50°±11°,49°±11°,48°±10°, respectively; p=0.121),& throwing shoulder TRM (162°±14°,160°±15°,161°±14°,respectively;p=0.770). CONCLUSIONS: Greater GIRLoss, GERGain, and TRMD in MUCL-injured-pitchers compared to uninjured-pitchers implies these variables may be related to increased-MUCL-injury-risk, especially since GIRLoss>18° and TRMD>5° demonstrate an increased MUCL injury risk. Shoulder rotational motion and deficits do not vary among HS, COLL, and PRO levels of pitchers.","PeriodicalId":18500,"journal":{"name":"Medicine & Science in Sports & Exercise","volume":"698 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74747875","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}

The magnitude of these effects may be dependent on compliance to the intended exercise prescription (ExRx), but few studies in cancer survivors have reported this information. This study examined breast cancer survivors’ ExRx compliance during a personal training (PT) or group-based exercise (GBE) intervention. METHODS: Women (N=26) with stage I-II breast cancer who had completed chemotherapy and/or radiation treatment within the previous year were randomly assigned to PT or GBE for 8 weeks. All participants received supervised exercise twice per week for 60 minutes a session. Participants were compliant to aerobic ExRx if they completed 20-30 minutes at 50-80% of heart rate reserve. Participants were compliant to upper and lower body resistance ExRx if they completed 2-3 sets of 8 repetitions within 50-80% of 1RM for chest and leg press. Compliance to aerobic, upper, and lower resistance ExRx was coded dichotomously (yes/no) for each session, then summed and divided by the number of sessions attended to calculate percent compliance. Independent t-tests examined differences in ExRx compliance between PT and GBE. Results are reported as mean±SD. RESULTS: Participants were aged 52±8.5 years, and 13.4±5.1 months post diagnosis. Of the N=24 who completed the intervention, exercise session attendance was 15.8±0.5 (99%) in PT, and 13.4±1.0 (82%) in GBE out of 16 possible sessions (p=.000). Compliance for aerobic ExRx was 77.2±0.17% in PT, and 70.1±0.17% in GBE (p=.41). Compliance for upper body resistance ExRx was 76.0±0.37% in PT and 82.4±0.20% in GBE (p=.597). Compliance for lower body resistance exercise was 80.2±0.23% in PT and 87.9±0.21% in GBE (p=.40). CONCLUSION: Exercise session attendance was higher in PT. Overall ExRx compliance was >70% for aerobic, >80% for resistance, and similar in PT and GBE. With growing support for establishing exercise programs for cancer survivors, it is important to determine sustainable and scalable delivery modalities. GBE may be more resource conscientious than PT, and this study suggests GBE can achieve comparable ExRx compliance to PT. Future exercise intervention studies in breast cancer survivors should examine how ExRx compliance affects health and/or fitness outcomes.","PeriodicalId":18500,"journal":{"name":"Medicine & Science in Sports & Exercise","volume":"449 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79681260","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}
